Answer:
<u><em>The benefits of genetic diversity include:</em></u>
- 2- species survive despite negative mutations
- 4- species adapt to ever-changing environments
- 5-gene pool is strengthened
Explanation:
Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.
Several alleles within a population's gene pools leads to higher diversity. These may become beneficial, as the environment of the organism changes.
Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.
Agents that paralyze skeletal muscle by simple competitive inhibition of acetylcholine at muscle receptor sites are called?
a. nondepolarizing
b. depolarizing
c. antagonizing
d. repolarizing
Answer:
a. nondepolarizing
Explanation:
As the nerve impulse arrives, the synaptic end bulbs of the motor neurons release acetylcholine in the synapse. Acetylcholine binds to its receptors present at the motor endplate. This results in the opening of an ion channel in the ACh receptor to allow the movement of the Na+ into the cell. This makes the inside of the muscle fiber more positively charged, that is, depolarized.
Depolarization triggers a muscle action potential. Drugs or chemicals that paralyze skeletal muscle by competitive inhibition of acetylcholine at muscle receptor sites are called non-depolarizing as they do not allow the acetylcholine to facilitate the depolarization of the muscle fiber.
Answer:
bioluminescent-from the word you get bio-somthing with connection of biology also luminous-something deal with light hence what bioluminescent molecules are living organism eg of special chemical are luciferin and luciferase and photoprotein
