Answer:

The correct answer is A hormone local regulator synaptic signal.

Explanation:

Hormones are called chemical messengers because they carry chemical and biochemical information from one cell to another cell by a process called signal transduction.

      The hormonal signal transduction is generally mediated by endocrine signaling in which hormone is secreted from one gland and then is transported via the blood stream to binds to the receptor present in the target cell.

Mila [183]

A change in temperature affects an enzyme by causing the enzyme to change it's shape.

<h3>what is an enzyme?</h3>

An enzyme is a substance that catalyzes chemical reactions.

  • Temperature is one of the major factors that aid enzymes action.

  • Increase in temperature could increase the rate of enzyme.

  • However, at a very high temperatures, the enzyme can be denatured thereby changing it shape or structure and the enzyme may no longer bind to the substrate or function effectively this will then reduce the rate of chemical reaction.

Therefore, a change in temperature i.e very high temperature can change the shape of an enzyme.

Explain what frame shift means and is it more or less likely to cause a noticeable mutation than a substitution
harina [27]

Answer:

A frameshift mutation can be described as a genetic mutation in which a single nucleotide or more than one nucleotide is inserted or deleted from the sequence of the DNA. As the gene expresses itself in the form of triplets of a genetic code, insertion or deletion can cause devastating changes in the genetic code due to which wrong proteins will be synthesized.

Frameshift mutations can be more noticeable than the substitution mutation. In a substitution mutation, only one of the nucleotides is shifted with another. The entire genetic code is not affected by it.
