The answer is A.

Twins form in one of two ways:
Identical twins occur when a single fertilized egg splits into two.

<span>I suspect this question should read "How long does a red blood cell live." A red blood cell lives for between 100 and 120 days. It takes 7 days for a new red blood cell to develop from stem cells. Stem cells are similar to base cells. They can also be seen as a general template from which specialized cells are made. Stem cells can be taken from a newborn baby's umbilical chord or extracted from an adult blood donor's blood.</span>

Which synapse(s) are specifically responsible for the habituation of the withdrawal response?
fredd [130]

<u>Sensory neuron to motor neuron</u> are specifically responsible for the habituation of the withdrawal response.

  • The withdrawal reflex, which is the automatic withholding of a limb from a painful stimulation, is what is known as this automatic reaction.
  • Humans are shielded by this reflex from tissue necrosis brought on by exposure to noxious stimuli like pain or heat. Either the upper or lower limbs may experience it.
  • A somatic reflex, like the withdrawal reflex, and a visceral reflex, an autonomic reflex, differ in that the latter has an efferent branch.
  • The lower motor neuron in the ventral horn of the spinal cord, which immediately projects to a skeletal muscle to produce its contraction, is the output of a somatic reflex.

A researcher is studying different mutations in yeast. He isolates one yeast strain that fails to properly form replisomes. When
olga nikolaevna [1]

Answer:

The correct answer is "both Cdc6 and Cdt1"

Explanation:

The replisome is a complex molecular system that allows for the replication of DNA in yeast. There are multiple genes that participate in the replisome function, however if a researcher finds out that a yeast strain fails to properly form replisomes it is very likely that the genes that might be mutated are both Cdc6 and Cdt1. Cdc6 and ORC are the genes that send the signal to the yeast to start the replisome formation, and Cdt1 is a DNA replication factor that if it is mutated it could cause that yeast is not able to form the replisome.
