Answer:
The hamsters were all brown because one side gave all dominant genes.
Explanation:
In the question, it tells you that one group of hamsters all had the genotypes BB. The other group had the genotype bb. In biology, capital letters represent dominant traits and lowercase represent recessive traits. Using this knowledge, we now know that one hamster has all dominant genes, while the other had all recessive genes. In this example, we will only need to use one law of inheritance: the law of dominance. In the law of dominance, if an individual inherits two different alleles (B & b) and only one phenotype is visible (the brown of B), then that allele is dominant. That explains why the hamsters are all brown! Each hamster has one dominant allele that came from the hamster that had BB. Now, you might wonder where the Punnett Square ties into this. A Punnett square is used to track the alleles of organisms. If you draw a Punnett square, you'll be able to see that each box has Bb inside of it. This means that each hamster offspring carries one dominant and one recessive gene inside of it. While they all have a b, the dominant B gene is also there, so the hamsters are all brown. I'm sorry this is so wordy, but I hope this helps!
Answer:
An insertion changes the number of DNA bases in a gene by adding a piece of DNA. As a result, the protein made by the gene may not function properly. Deletion. ... This type of mutation occurs when the addition or loss of DNA bases changes a gene's reading frame.
Answer:
reservoir.
Explanation:
The reservoir is a component of the biosphere that serves as a long term storage unit for the nutrients or the water. It is a storage space for fluids.
Much of our understanding of human sex-ual response came from the early studies of<u> </u>Masters and Johnson research.
<h3>
What is the Masters and Johnson technique?</h3>
The Masters and Johnson technique begins with a se-x history and medical tests of the couple to rule out any physical issues. To assist the couple get past their se-x phobias, therapists then use activities that emphasize giving and receiving sensuous pleasure—not necessarily se-x-ual pleasure.
<h3>
What Research Did Masters and Johnson Conduct?</h3>
Particularly for their theory of a four-stage model of se-x-ual response (also known as the human se-x-ual response cycle) and their investigation of se-x-ual response in the elderly, William Masters and Virg-inia Johnson have received widespread acclaim for their contributions to se-x-ual, psychological, and psychiatric research.

Answer:
6 CO2 + 6H20 + light – C6H1206+6 02
Explanation:
The conservation law states that the number of atoms stay the same before and after a reaction. Consider the following reaction:
6 CO2 + 6H20 + light – C6H1206+6 02
There are 6 atoms of carbon before the reaction, after the reaction also the number of carbon remains 6.
There are 18 atoms of oxygen before the reaction. The number of oxygen remains 18 after the reaction.
There are 12 atoms of hydrogen before the reaction. The number of hydrogen remains 12 after the reaction.
Hence, this reaction is the proper evidence of the conservation law.
