Answer:
The correct answer is - red blood cells are biconcave.
Explanation:
RBC or the red blood cells are the cells that play an important role by many means such as transferring nutrients, hormones, and oxygen throughout the body. The transfer of the oxygen is accompanied by the help of hemoglobin, a protein that carries oxygen and takes it to the different sites in the body.
These cells are biconcave which helps them to provide more cell surface area to grab or attain maximum space for hemoglobin which helpful in oxygen significant oxygen-carrying capacity of Red blood cells.
Thus, the correct answer - red blood cells are biconcave.
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:
Yes.
DNA or deoxyribonucleic acid is a thread like structure that contains Hereditary and Genetic materials such as chromosomes.
Scientists call it the 'Book of life'.
