Answer:
This question lacks options, the options are:
A) The products of photosynthesis inhibit respiration
B) The products of photosynthesis are also the products of respiration
C) The reactants of photosynthesis are also the reactants of respiration
D) The products of photosynthesis are the reactants of respiration
The answer is D
Explanation
Photosynthesis and cellular respiration are two unique and distinct metabolic activities/processes. Photosynthesis is carried out by green plants and it involves the synthesis of glucose and oxygen using carbon dioxide (CO2) and water (H2O). Cellular respiration, on the other hand, occurs in every living organism and it involves the synthesis of energy using glucose and oxygen to produce carbon dioxide and water.
Based on the description of the two processes above, it can be observed that both processes are interrelated in the sense that the products of photosynthesis (CO2 and H2O) are the reactants of cellular respiration (C6H12O6 and O2).
The equation is as follows:
1) Photosynthesis:
6CO2 + 6H2O --> C6H12O6 + 6O2
2) Cellular respiration:
C6H12O6 + 6O2 --> 6CO2 + 6H2O

What is the percentage of Thymine if you have 18 % Guanine in a strand of DNA?
32
25
22
18
Answer: 32%
Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine, in equal amounts. That being said, the amount of cytosine is equal to the amount of guanine, meaning that it is 18% as well. Since 18+18=36, you know that the remaining 64% is adenine and thymine collectively. To figure out how much of each base there is, you could divide 64% between each nitrogenous base to get 32% each.

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer or soap and warm water for two minutes; then they dried their hands with a paper towel. The standard of comparison was rubbing hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. The sanitizer advertisement claimed to kill bacteria more effectively than any soap. After washing, hands were swabbed and then the swab applied to a culture plate and incubated. Finally, the bacterial cultures were counted. Students using the antibacterial santizer had the lowest bacterial culture count. What is the control in the experiment? A) washing with soap B) rubbing vigorously C) the time: two minutes D) rubbing hands in warm water
Answer:
The correct answer is - option D. rubbing hands in warm water.
Explanation:
The control group or the control is the variable or that is used in an experiment to check if the results are actually due to the experiment or to compare the result or effect of the experiment.
In this experiment, the independent variables are soap and the sanitizer and the dependent variable is the count of bacterial culture. To check the result or to compare the result that results are due to the experiment the control group is rubbing the hand vigorously in warm water.
A horse galloped at 40 km/hr, then it began to slow down. The horse slows down at 20km/hr. We know the kinetic energy of the horse (1 BLANK) by a factor of (2BLANK). The relationship between kinetic energy and speed is (3 BLANK).

2 blank: 2x, 4x, 1/2x, 1/4x
3 blank: directly proportional, linear OR square, nonlinear
Answer:
decreased, 1/2x, linear
Explanation:
A horse galloped at 40 km/hr, then it began to slow down. The horse slows down at 20km/hr. We know the kinetic energy of the horse decreased by a factor of 1/2x. The relationship between kinetic energy and speed is linear.
What is average speed?The average speed has been defined as the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
Kinetic energy has been defined as the energy of the object that occurs due to the motion of the object. The total work needed by the body to starts accelerating it by the help of given mass which has supplied from the rest position and its mentioned velocity.
The energy body gets due to the process of acceleration by this the body will able to main the kinetic energy of the body without changing the speed of the body. The energy which has been stored in the body or any object by the help of the particular position or the proper arrangement of the parts is known as potential energy.
There will be no effect of the outside environment on the potential energy that present inside the body. The kinetic energy decrease or increase with change in the velocity.
Therefore, A horse galloped at 40 km/hr, then it began to slow down. The horse slows down at 20km/hr. We know the kinetic energy of the horse decreased by a factor of 1/2x. The relationship between kinetic energy and speed is linear.

- nuclear Fusion of lighter elements into heavier elements
- muleteer of heavier elements into lighter elements
- radioactive decay of lighter elements into heavier elements
- radioactive decay of heavier elements into lighter elements
please I need this ASAP
Answer:
A
Explanation:
Nuclear Fusion of lighter elements into heavier elements is the process produces the largest amount of energy given off by stars. Thus option A is correct.
What is Nuclear fusion ?Nuclear fusion is process where two or more atomic nuclei fuse together and form a single heavier nucleus, here the matter is not conserved and the mass of the fusing nuclei is converted to energy.
When deuterium and tritium fuse together and form helium atom, fast neutron, the remaining extra mass is transformed into kinetic energy.
The participating nuclei should be brought together by a nuclear forces which become active and glue to the nuclei together, it shows no pollution effect with less nuclear waste.
The nuclear fusion energy used to clean and produces a minimum amount of nuclear waste compared to nuclear fission reactions and the fuel for fusion, Deuterium, and Tritium are available in nature, viable alternative power source in the coming centuries.

How does the probability of success of fertilizations change from predators? (specifically fish fertilizations and predators like turtles)
Answer:
It depends largely on environment!
Explanation:
External fertilization usually occurs in aquatic environments (fish) where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization can then take place. Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time. The release of the reproductive material may be triggered by water temperature or the length of daylight. Nearly all fish spawn, as do crustaceans (such as crabs and shrimp), mollusks (such as oysters), squid, and echinoderms (such as sea urchins and sea cucumbers). Pairs of fish that are not broadcast spawners may exhibit courtship behavior. This allows the female to select a particular male. The trigger for egg and sperm release (spawning) causes the egg and sperm to be placed in a small area, enhancing the possibility of fertilization.
When it comes to spawning, where large clutches of eggs will be fertilized at the same time it increases the probability of survival amongst the eggs, only by sheer force of numbers. If fish only fertilized small clutches there would be little to no survivors due to predator's population. Because of predators like Turtles, a lake with little predator's (turtles) will have a higher chance of egg survival rate. On the other hand, Lakes and ponds will have A lower survival rate for egg clutches with more predator's, like turtles.
Hope this helps! let me know in the comments if I need to answer any other parts of this prompt, I would be happy too.
Un carnera de lana negra se cruza con una oveja de lana blanca y tienen al menos un cordero de lana negra. El canero tiene las orejas largas y la oveja las tiene cortas. Sabiendo que el color de la lana sigue una herencia dominante para el color blanco y que esta especie puede tener las orejas Cortas, medianas o largas (herencia intermedia), deduce qué fenotipos se esperan en la F1 y su proporción. Cuadro de punnett necesito?
Answer:
Fenotipos de la F1: 50% de la progenie muestra orejas medianas y lana blanca, mientras que el otro 50% muestra orejas medianas y lana negra. En este caso en particular, el cuadro de Punnett no es necesario pero resulta de gran utilidad para visualizar la cruza.Explanation:
Datos disponibles:
El color de la lana sigue una herencia dominante para el color blancoEsta especie puede tener las orejas cortas, medianas o largasCruza: carnero de lana negra y orejas largas X oveja de lana blanca y orejas cortasProgenie: al menos un ejemplar con lana negraPodemos suponer que para el gen determinante del color de lana, el alelo dominante L determina lana blanca, mientas que el alelo recesivo l determina lana negra. También podemos suponer que para el gen que determina la longitud de las orejas, el genotipo LL expresa orejas largas, el genotipo Ll expresa orejas medianas, y ll expresa orejas cortas por tratarse de herencia intermedia. Entonces:
B--> Lana Blanca
b --> Lana Negra
LL --> Orejas largas
Ll --> Orejas medianas
ll --> Orejas cortas
Cruza: carnero de lana negra y orejas largas X oveja de lana blanca y orejas cortas
Puesto que en la progenie habia por lo menos un ejemplar con lana de color negro, podemos suponer que la oveja era heterozigota para la caracterítica en cuestión, ya que es la única forma de obtener un genotipo recesivo en la F1.
Parentales) bb LL x Bb ll
Gametos) bL, bL, bL, bL Bl, bl, Bl, bl
Cuadro de Punnet) Bl bl Bl bl
bL BbLl bbLl BbLl bbLl
bL BbLl bbLl BbLl bbLl
bL BbLl bbLl BbLl bbLl

F1) Genotipo: 8/16 BbLl
8/16 bbLl
Fenotipo: 8/16 o 50% animales de lana blanca
8/16 o 50% animales de lana negra
16/16 o 100% animales de orejas medianas
Posiblemente no sea necesario utilizar un cuadro de Punnet con la cruza mencionada. Sabiendo los genotipos paterno y materno es posible determinar las proporciones fenotipicas de la F1 sin realizar el cuadro de Punnet.
Para longitud de orejas se puede deducir que todos los ejemplares en la F1 serian heterocigotos, expresando orejas medianas. Esto se debe a que la cruza ocurre entre un homocigota dominante y un homocigota recesivo para esta característica.En tanto que para la caracteristica del color de lana se podria asumir que la mitad sería blanca y la otra mitad negra, puesto que la cruza es entre un homocigota recesivo y un heterocigota.Aun así, mientras haya pocos genes dialélicos involucrados en la cruza, el uso del cuadro de Punnet siempre resulta útil para una mejor visualización de la cruza.

If a DNA strand has 26% cytosine, what percent thymine will each new strand have after replication?
Answer: Each new strand would have 24% thymine
Remember the base pairing rules: cytosine with guanine and adenine with thymine, in equal amounts. Since you know that there is 26% cytosine, the amount of guanine is also 26%. 26+26=52, so that means that 52% is cytosine and guanine collectively, which means that the remaining 48% is adenine and thymine. Since these are also equal, you could divide 48% between the two bases to get 24% each.

What is the role of the carbon cycle? (100 points) Detailed answers please!
Answer:When new life is formed, carbon forms key molecules like protein and DNA. It's also found in our atmosphere in the form of carbon dioxide or CO2. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
Explanation:
Answer:
the carbon cycle is the process in which co2 i
travels from the atmosphere to organisms and back to the atmosphere. The four steps of the carbon cycle are photosynthesis, decomposition, respiration, and combustion. Then carbon cycle starts by carbon moving from the atmosphere to plants. The carbon then moves from plants to animals. And then it moves from plants and animals to soil. The carbon then moves from living things back to the atmosphere. Carbon also moves to the atmosphere from the burning of fossil fuels. carbon also moves from the atmosphere to the oceans. Carbon is a life sustaining element . The carbon cycle is important because it move carbon throughout different ecosystems.

HELP PLS First, Demetri will test the three solutions containing milk (lactose).
He begins the experiment by preparing the lactase enzyme solutions. In one beaker he dissolves 1 lactase tablet in 100 mL of water at room temperature. He stirs the mixture until the tablet has dissolved completely. He repeats this process in a second beaker, and then heats the beaker until the solution is boiling.
Demetri then tests these three milk (lactose) solutions for the presence of glucose:
milk in water
milk and lactase enzyme in water
milk and heated lactase enzyme in water
Test Tube 1 - Milk (Lactose): Demetri fills the first test tube one-quarter full of milk. Then, he slowly adds water to the milk until the test tube is three-quarters full. Using the stirrer, Demetri thoroughly mixes the solution. Then he inserts the test strip for 30 seconds and records its color.
Test Tube 2 - Milk (Lactose) and Lactase Enzyme: Demetri fills the second test tube one-quarter full with milk. He then adds the lactase-and-water solution until the test tube is three-quarters full. He uses a stirrer to thoroughly mix the solution. Next, Demetri inserts the test strip for 30 seconds and records its color.
Test Tube 3 - Milk (Lactose) and Heated Lactase Enzyme: Demetri fills the third test tube one-quarter full with milk. He then adds the heated lactase-and-water solution until the test tube is three-quarters full. After stirring, Demetri inserts the test strip for 30 seconds and records its color.
According to the test strips, which of these milk solutions contained glucose?
Answer:
2nd test tube, because test strip color turned to green, which indicates this test tube solution contained glucose.
Explanation:
Lactase will break down the lactose into glucose and galactose. In first test tube there is no such activity because there is no lactase presented. In 3rd test tube as the enzyme is heated so it is get decomposed so in this case also there is no activity of lactase enzyme.
The second tube is the tube that contained glucose.
We can arrive at this answer because:
Lactase is a protein.This protein has the function of breaking lactose into smaller molecules, which are glucose and galactose molecules.This protein is sensitive to high temperatures and loses functionality in very hot environments.In the case of the tests used in the question above, we can say that in the first test tube, the lactase solution was not added, so the lactose was not broken down. The lactase solution was added to the second test tube, where the lactose was broken down generating glucose and galactose. In the third test tube, the heated water prevented the lactase from acting and therefore it cannot break down the lactose.
Therefore, only the second tube has glucose.
