Bile salts decrease the surface tension of the urine sample, that’s why the sulfur will sink in a sample from an individual with impaired liver function since it contains high levels of bile salts.
Bile salts caused the sulfur powder to sink because bile salts decrease the surface tension of the urine sample.
Liver function test are test procedures that are used to diagnose and monitor liver disease or damage.
When the liver is malfunctioning, such as in cases of hepatitis and cirrhosis, high level of bile salts are present in the urine. This is as a result of high serum bilirubin.
One of the fastest methods to carry out a test for liver function is sprinkling sulfur powder onto a sample of urine.
Surface tension is the quality displayed by water that enables substances of greater density float on it.
The bile salts is able to decrease the surface tension of the urine sample causing the sulfur powder to sink.

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.

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.
In the chemical equation for photosynthesis, carbon dioxide and water are converted to glucose and oxygen.

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
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.

- 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.

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 city is considering switching to geothermal power for their electricity needs. Which of the following is an advantage of this plan?
1. It is commonly used across the entire United States.
2.It uses less land area than gas power plants.
3.It uses water to power large turbines.
4.It in inexpensive to build.
It uses water to power large turbines.
Geothermal power taps on the energy of natural steam from the earth's lithosphere.
Explanation:
The heat from deep in the the lithosphere heats up underground water into high-pressure steam trapped in within the rocks. Boreholes are sunk to tap on the potential energy of this high-pressure steam to turn large dynamo turbines that convert the steam energy into electricity.
The biggest advantage, moreover, is the fact that this method of electricity generation does not emit greenhouse emissions as compared to gas plants that burn hydrocarbons that release CO₂.

Explanation:
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.
