Answer:
(B) calmodulin
Explanation:
Calcium in cells acts as second messenger molecule which regulates the very important physiological and cellular process of cell-like neurotransmission, cell migration, secretion, fertilization and many others.
Calcium acts as a messenger by binding to a calcium-binding protein called calmodulin. Calmodulin forms complex with 4 calcium ions through the side amino acids present in the structure of calmodulin.
Thus, calmodulin is the correct answer.
Answer:
A) 1:2:1
Explanation:
Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles. Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.
In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.
Thus, Option-A is the correct answer
A sea sponge is what mimics a synthetic sponge
The mailman could not be the father.
The mother did not give the baby its B type blood, and a type O father could not have given this blood type. Therefore, the mailman did not father the baby.
The both decrease genetic variation
