Answer:

High Temperature, X-rays, Radiation, Some Chemicals

Explanation:

In general, mutations happen due to some error in the DNA duplication process, however, there are certain factors in the environment that can increase the incidence rate of these genetic errors. Excessive exposure to x-rays, substances present in smoke, ultraviolet light, excessive temperature, nitrous acid and some dyes present in food, for example, can favor the appearance of mutations. In general, we can say that mutations can be caused by high temperature, X-rays, radiation, some chemicals.

How can an ecosystem support a variety of organisms in a rainforest
Andrews [41]
I'm not sure what kind of answer you're looking for, but due to the great amount of sunlight, there's lots of energy in rainforests. That energy is stored in plant vegetation, which gets eaten by animals. The canopy of the rainforest also provides many places for animals to live and plants to grow. It also provides interactions between species. For example, t<span>here are some plants in the canopy called bromeliads. Frogs and some other animals use these for hunting & laying their eggs.</span>

You experimentally apply a toxin to a muscle and find that it does not contract when you electrically stimulate the motor neuron
Furkat [3]

The question provided is not complete as it lacks the group of choices, however the group of choices are given as follows:

A. A contraction fails to occur because an action potential is not generated in the muscle cell.

B. A contraction fails to occur because this toxin directly prevents ion release from intracellular stores.

C. A contraction fails to occur because neurotransmitter release by the motor neuron is blocked at the neuromuscular junction.

D. A contraction fails to occur because this toxin prevents cross bridge formation and thereby directly prevents contraction.

E. C and D are both true

Answer:

The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.

Explanation:

A muscle contraction takes place when action potential bring to muscles by nerves, which is traveled with the help of motor neuron and imitated the muscle contraction.

Acetylcholine or Ach is a chemical messenger to bring the nerve impulses between a nerve and a muscle. If the receptor is block with applying toxin muscle will not contract as ACh will not be able to propagate the nerve impulse to the muscle so there will be no action potential.

The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.
