A hypertonic solution has:
Fewer water molecules outside the cell than are inside the cell
More water molecules outside the cell than are inside the cell
The same number of water molecules inside and outside of the cell
No water inside or outside of the cell
A hypertonic solution has:
Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.
What is hypertonic solution?The cell is in a hypertonic solution because it lost water through osmosis and shrunk.A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.Thus, option "A" is correct.

In the nebular hypothesis, why did the nebula start to collapse?
Answer:
The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

The word transcribe means 'to write out' and the word translate means 'to express in a different language'. Review the meanings of transcription and translation in protein synthesis. How do the technical meanings of these words relate to meanings of the words in ordinary language.
The word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.
What is the genetic code?The genetic code is a series of instructions that indicate how to synthesize proteins from a given gene sequence.
During transcription, the DNA gene sequence is transcribed into a messenger RNA (mRNA).
During translation, triplets of nucleotides or codons in mRNA determine specific amino acids in the growing protein sequence.
In conclusion, the word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele is 0.72. What percentage of the rats are normal sized? (3 points)
Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%

Cell theory states that all living things contain one or more cells. why do you think chill theory meets the definition of a scientific theory? Do you think it should be a scientific law? Explain your response.
The cell theory meets the definition of a scientific theory, yes because the scientific theory refers to the well-proven explanation of aspects of the natural world.
What does the cell theory claim?Cell theory states that all living things are composed of cells, the basic structural and organizational unit of all organisms, and that all cells come from pre-existing cells.
The cell theory is a scientific theory because it managed not only to theorize but also to prove in a way that supports the arguments of a scientific theory. When a theory can be proved in general, it becomes a law, so yes it could be a law.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem. All of the following must be addressed in your response to receive full credit:
a. Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer.
b. Explain what happens to the energy that is not transferred from one organism to another.
c. Explain why there are typically fewer organisms at the top of an energy pyramid.
d. Use specific numbers and calculations to support your explanation.
The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.
a)
When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain. This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next. Further deterioration will occur when these herbivores are consumed by secondary consumers. Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.b)
Additionally, the energy flow in a food chain adheres to the 10% law.This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.c)
There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms. Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.d)
For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.learn more about ecosystem here: https://brainly.com/question/842527
