Answer:

Cells of skin, for instance, have highest mitotic index.

Explanation:

Many cells are capable of dividing rapidly. <u>For example</u>, in plants, the cells near the root tip in the apical meristem divide rapidly to push through the soil because the root cap detects the gravity and direct rapid division and growth of cells near the tip.

If we take muscle, skin, kidney, and lung as examples that are given in real question, <u>skin cells have the highest mitotic index because they need to get replaced most frequently</u>.

Functions of astrocytes include all of the following except
Neporo4naja [7]

The question is incomplete. The complete question is as follows:

Functions of astrocytes include all of the following, except

A) performing repairs in damaged neural tissue.

B) guiding neuron development.

C) functioning in action potential transmission.

D) maintaining the blood-brain barrier.

E) creating a three-dimensional framework for the CNS.

Answer:

Functioning in action potential transmission.

Explanation:

Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.

Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.

Thus, the correct answer is option (c).

Colony collapse disorder that has been decimating bee colonies was first reported around 2006. Massive numbers of honey bees wer
BigorU [14]

This information can be useful to agriculture because bees are major pollinators of crops, so it is important to know which pesticides to manage in order to avoid risk to bee survival. That is option B.

Bees are one of the social insects that lives in societies that are based on a caste system.

Each caste performs a special task or series of tasks that serves as an economic importance to the agricultural system.

Pests such as parasitic mites cause poor agricultural yield. By using pesticides, which are protective chemicals, farmers have greatly improved crop yield.

The bee workers while in search of pollen from crops can be harmed from the pesticides that is being used to control parasitic mites. This can lead to Colony collapse disorder of the caste system of bees.

Therefore,  it is important to know which pesticides to manage in order to avoid risk to bee survival.

Condensation often gathers in the bottom of agar slants. why is it important in this exercise to limit condensation on plates bu
vekshin1
<h2>Answer:</h2>

Because condensation on the slant effects the bacterial growth in the test tube.

<h3>Explanation:</h3>
  • When agar is solidify in the test tube tilted, it takes a shape of slide on one side of the tube which is known as slat.
  • Slant is used instead of petri dishes because they provide more surface area for growth.
  • Water in the slat can invade the test tube, making agar unstable and the bacterial growth on the slat will be affected by moisture in bottom of slant.
  • In petri dishes, it is no big problem of moisture condensation.
