Answer:
Viruses are non living.
Explanation:
Viruses are small structures that can reproduce only in the cell of the host. That means they can’t be classified as a living thing. Their composition is very basic, they consist of only two components. One component is DNA and the other one is the protein mantel. They are not able to grow nor to do the metabolic process. Even if they are very small and simple, they are a big threat to the human organism.
Answer:
There is no question to this text.
Explanation:
Answer:
The correct answers would be:
- This is because the parents were for pea color were heterozygous
- Because there are only two options for pea color, the plants’ pea color is a case of simple Mendelian genetics.
Yellow pea plants cross to produce offspring with green pea. It is possible only when both the parents were heterozygous. Then only they would be able to produce offspring with yellow and green peas in the ration 3:1.
It is an example of simple Mendelian genetics or simple monohybrid cross as only two alleles (yellow and green) are involved in the production of phenotype (seed color).
The same is explained in the cross below.
Answer:
the answer is date of birth
Answer:
Because the probability of hemophilia would be 1:4
Explanation:
Hemophilia is a disease that comes with a sex chromosome (pair 46).
It is a recessive allele associated with chromosome X, women have two X chromosomes they can carry it, but they don't have it because they have another dominand allele non-hemophilic.
If you draw a Punnet square with a non-hemophilic father and a carrying mother, you'll found you have 1:4 chances of having a baby boy with hemophilia.
Carrying mother = X(H)X(h)
Father = X(H) Y
