as acid has pH value between 0 to 7.
A baby's immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus's immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. If gene pair contains a dominant allele, the the offspring will show this dominant trait
Answer:
An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population. Natural selection results in organisms that are more likely to survive and reproduce.
Answer:
Option D, Zero out of four (0%)
Explanation:
As we know, achondroplasia is an autosomal dominant pattern. Now a girl having normal stature mate with a partner who also has a normal stature.
Thus let us assume -
Allele for disproportionately short arms and legs be represented by "A"
while allele for normal stature be represented by "a"
Now genotype of parents would be
Female - aa
Male - aa
Thus,
aa x aa
aa, aa, aa, aa
Thus, option D is correct.
