Biology
1 answer:
WINSTONCH [101]3 years ago
6 0

Answer:

a) genetics and heredity: Genetics can be described as the study of genome or DNA of an organism. Heredity refers to the traits which are passed on from the parents to the offsprings. Not all of the genome of an individual is similar to the parents. Hence, genetics refers to the genome of an individual and heredity refers to the traits which pass from the parents to the child.

b) Dominant and recessive trait: A dominant trait is caused due to a dominant allele. A dominant allele is the allele which can mask the effect of the other recessive allele. Hence, a person can be homozygous or heterozygous for the dominant trait. A recessive trait arises due to the recessive allele. A recessive allele is the allele which gets masked by the dominant allele.

Pure and hybrid: A pure offsprings contains the same genetic character for a trait. It is a homozygous offspring. A hybrind offspring contains different alleles or genetic characters and is heterozygous.

In some cascades, calcium acts via a calcium-binding protein
slavikrds [6]

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.

Organic sediment on lake bottoms and the ocean floor is broken down by microbes into inorganic forms of phosphorous in a process
murzikaleks [220]

Answer: Mineralization

Explanation: Phosphorous cycle moves through the rocks, water, soil, sediments and organisms.

The weathering of rock releases phosphate ions and other minerals. Plants take up the phosphate from the soil. Phosphorous is present in the form of organic phosphate which is broken down by the help of microorganism in the form of inorganic phosphate.

This process is known as mineralization.
