Answer:
All of the above are true.
Explanation:
The structure and function of components of the nervous system are altered by the process of aging. In late adulthood, there is alteration in the neuromuscular junction and the nerve conduction velocity is also reduced.
The age-related slowed response of the nervous system is a result of the loss of nerve fibers from the peripheral nerves with aging. Both myelinated and non-myelinated nerve fibers of the peripheral nervous system are affected by aging and are lost resulting in slowed conduction of nerve impulse.
Answer: The statement which summarizes the law of segregation is as follows :
During the process of gamete formation, two different forms of a gene ( also called allele) segregate from one another in a random manner and each gamete thus formed, receives one copy of gene.
This is called the law of segregation. It was proposed by Gregor Mendel.
For example- The gene for plant height in pea exists in two forms which are T ( dominant allele- represents tall height ) and t ( recessive allele- represents dwarf height ). If a plant is heterozygous ( having different alleles Tt), it will give two different gametes ( T and t ) during gametogenesis.
These alleles are segregated in accordance with the law of segregation.
Science cannot prove or refute the existence of God or any other supernatural entity.
