Describe the net movement of water when a dialysis bag containing a 0.2 M sucrose solution is placed into distilled water, which contains no solutes.
a. There will be no movement of water.
b. Water will move into the bag.
c. Water will move into the beaker.
d. There will be no net movement of water.
Answer:
b
Explanation:
The correct answer would be that water will move into the bag.
The 0.2 M sucrose solution in the dialysis bad has a lesser water potential when compared to the distilled water that has no solutes. By law, water moves from the region of higher water potential to the region of lower water potential. The dialysis bag will, hence, act as a semi-permeable membrane and allow water into the bad from the surrounding distilled water.
The correct option is b.

Which compares the problems associated with radioactive waste created from generating electricity using fusion reactions to waste created from generating electricity using fission reactions?
A. The radioactive waste from fusion reactions becomes less hazardous much sooner than the waste from fission reactions.
B. The radioactive waste from fission reactions becomes less hazardous much sooner than the waste from fusion reactions.
C. Although their radioactive wastes are hazardous for the same period of time, fusion reactions produce less waste than fission reactions.
D. Although their radioactive wastes are hazardous for the same period of time, fission reactions produce less waste than fusion reactions.
Radioactive waste from fusion reactions becomes less hazardous much sooner than waste from fission reactions, nuclear fusion is much safer than fission because it leaves no radioactive waste behind.
What is the difference between the two reactions?Both processes are natural, but they can also be done in a laboratory. While fusion occurs when two atoms are "crushed" to form a single atom of a new element, fission consists of the splitting of an atomic nucleus.
With this information, we can conclude that Radioactive waste from fusion reactions becomes less hazardous much sooner than waste from fission reactions, nuclear fusion is much safer than fission because it leaves no radioactive waste behind.

Which molecule in Diagram 11 is used to transport energy to other parts of the plant?
Answer:
The answer is Sugars, or sugar molecules!
Explanation:
The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap.
The molecule is Sugar ,transported principally as Sucrose, but originally as Glucose after photosynthesis and stored as starch in plants.
The sucrose is transported in the Phloem( one of the vascular tissues, the second is the xylem. They are located adjacent o each other.)The process of transportation is called, Pressure Flow Model. The process of moving the sugar through the plants is called Translocation.
There are two regions during transport of sugar in translocation. The source where the sugar is produced, that is the green leaves, and the sink where the sugar is metabolized.
Therefore the high concentration of the sugar at the source([plant leaves) increases the solute potential of the cell in the phloem of the leaves. This set up a gradients that draw water from the adjacent xylem into the phloem by osmosis.
The water influx increases the pressure potential of the phloem sap, and which makes the phloem turgid. The creates turgor pressure because of the increases of the phloem sap (containing sugar).The pressure leads to the bulk transport of the sap contain sugar (translocation) from the source( leaves) to the Sink.
At the sink, the sugar is withdraw . Thus the solute potential rises,(with a drop in pressure potential) and water return by osmosis back to the xylem for the process to continue with another transport.

Here is what I want you to do. Create a comic strip using one of the following websites. Some of the websites you must pay for, so DON'T PAY for them, just take a screenshot and send it to me in an email.
You can also complete the project using poster board. Either way is fine. Once completed with poster board, you must send it to me by taking a picture through an email.
The key to the assignment is to make sure you will model the structures of the cell and describe their functions. You will do this by completing a table that describes the functions of structures of the cell. The table should also identify factory parts or workers that have similar functions.
The comic strip is just a way to describe the cell structures. It's a scenario (scene) describing the events. The scene is of a reporter who visits a cell “factory” and interviews someone about the structures/organelles and how their roles in the cell are similar to those of a factory and its workers.

A certain plant species has seeds that remain dormant until heat stimulates them to germinate.
• Describe the process of succession that could occur with this species after a wildfire.
• Identify whether the plant species is dependent on succession events and explain how you know.
Answer:
Explanations: primary succession will take place because these plants will dominate after a wild fire has occured in the area since their growth is stimulated by heat hence the heat will result to the widespread of this type of plant
These plants are indeed dependant on succession events because they are only stimulated to grow through heat events
Secondary succession is that process which occurs after wildfires.
What is Secondary succession?In this type of ecological succession, the plants and animals recolonize a habitat after a major disturbance such as a devastating flood, wildfire, landslide, lava flow, or human activity etc.
Yes, the plant species is dependent on succession events because that event make the environment suitable for the growth of some plants so we can conclude that Secondary succession is that process which occurs after wildfires.

Explanation:
Genes A and B are neutral. A weakly beneficial mutation arises in the population. This mutation is 100 base pairs away from Gene A and 1000 base pairs away from Gene B. If this mutation were to go to fixation within the population, which gene would be more likely to go to fixation and what is the term for this process? Is there any reason to suspect that one or both of these genes may not go to fixation? Why or why not?
Answer:
Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.
Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close will have a few recombination events and are strongly bounded.
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be.
Genes that express 50% of recombination frequency or more are not linked genes.
To analyze the recombination frequency, we have to know that
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.
And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.
1,000,000 base pairs ------------------ 1% recombination frequency
1000 base pairs -----------------------X = 0.001% recombination frequency
100 base pairs ------------------------ X = 0.0001% recombination frequency
According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.
Sugar made in the process of photosynthesis to sent to the mitochondria to produce _____.
Answer:
energy
Explanation:
i just know it. i like science
Sugar produced in the process of photosynthesis to sent to the mitochondria, is used to produce energy in the form of ATP through the process of cellular respiration.
What is Cellular respiration?
Energy is produced in the body through the food we eat. The food is broken down into simpler substances which are absorbed by the cells and in the cells are used to produce energy.
Sugar is produced by the process of photosynthesis in plants which is sent to the mitochondria to produce energy in the form of ATP (adenosine triphosphate). The process of oxidation of food to produce ATP is called cellular respiration.
The process of cellular respiration consists of three processes which include glycolysis (breakdown of glucose into pyruvate), citric acid cycle, and the oxidative phosphorylation which produces about 34-36 molecules of ATP in the mitochondria of cell.

Conservation of Energy? Explain your reasoning.
Answer:

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
The increase in the reproductive success of a species will have the greatest impact on the - size of that species’ population. competition within other communities in the biosphere.. success of other populations in the community. tissues that comprise organisms of that species.
Answer:
size of that species’ population.
Explanation:
The increase in the reproductive success of a species will have the greatest impact on the size of that species’ population.
A reproductive success rate means more individuals survive birth and get added to the existing population. The more the number of individuals added to a population, the more the size of the population of the species.
An increase in the population size of a species will only increase intra-species competition for resources but have no real impact on the success of other populations in the community.

Helping someone move her couch after she helped you study for an upcoming examThe biological relationship between cleaner fish and large predators in the ocean, in which cleaner fish keep the predatorExplanation:
Altruism is a biological concept used to describe the action of an organism which reduces its own fitness but increases the fitness of another organism. Reciprocity, on the other hand, refers to cooperation between two unrelated organisms in which the beneficial actions of one to the other is reciprocated either in the short or medium term.
Giving a few canned goods to the local food bank for its annual food drive is an action done to benefit those that patronize the food bank without any hope of it being reciprocated. Hence, it is considered altruism.
Helping someone move her couch after she helped you study for an upcoming exam and the biological relationship between cleaner fish and large predators in the ocean, in which cleaner fish keep the predator are both considered reciprocity.

Movement gives organisms the ability to move away from or towards an external stimulus depending on whether it is a detrimental stimulus or a favourable one.
Examples of stimuli are:
Light: All organisms respond to the presence of light. Some stay away from it and remain at sleep until the sun goes down. They are called nocturnal. Others gravitate towards it. Plants always grow towards light.Temperature: Some organisms favour cold environments, other the temperate parts of the earthSound: The sound of a carnivorous animal such as the lion will put a deer to flight.

If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support your survival?
Answer:
would increase
Explanation:
The pyramid of biomass is a diagram that exhibits the total biomass of the organisms at different trophic levels, which are required to support life in a given ecosystem. This pyramid usually starts with producers situated on the bottom (e.g., plants), then continues with the organisms that eat these primary consumers (herbivores), after with secondary consumers (carnivores), and so successively. The pyramid of biomass indicates the amount of mass of 1-primary producers required to support the life of the primary consumers, 2- primary consumers needed to support the life of the secondary consumers, 3-secondary consumers needed to support the life of the tertiary consumers, and so successively for each trophic level. In this diagram, the trophic level with a higher amount of biomass (and energy) is usually represented by the producers (i.e., by organisms on the bottom), and this amount of biomass decreases as long as more levels are considered. In consequence, if more food from secondary consumers is consumed, it will produce an increase in the percentage of biomass that is needed to support life.
