Answer:
The options are not given but they are gotten from another websites.
A. Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.
B. Capillaries surrounding the brain have pores and are surrounded by membranes of astrocyte cells.
C. Capillaries surrounding the brain have no pores and are not surrounded by membranes of astrocyte cells.
D. Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.
The correct answer is option A.
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.
Explanation:
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells because
Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells while capillaries in the periphery Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.

Explanation:
This is the answer for plato users.
Proteins are polymers of amino acids. There are a fixed set of amino acids that are involved in the making of a protein. These amino acids are varied in number and type to give rise to different combinations in a polymer. This creates a diversity of protein molecules.
The amino acids link to other amino acid in the polymer through the formation of a peptide bond between them. It forms when the carboxylic group of one amino acid molecule reacts and binds to the amino group of the other molecule.
Answer:
Asexual reproduction can be described as a process in which daughter cells are produced which are 100% identical to the parent cells. Unlike the process of sexual reproduction, no recombination occurs in asexual reproduction. Hence, no variability is produced when organisms reproduce by this method.
<u><em>As there will be lack of variability in asexual reproduction, the whole of the particular species might become endangered or extinct due to a disease or due to other factors like pests.</em></u>
