A scientist researching salamanders has obtained two different specimens. Under what conditions would he classify them as belong
mafiozo [28]
<span>This is the condition under which he would classify them as belonging to different species - the two salamanders cannot mate to produce a fertile offspring. If these two lizards belonged to the same species, they would normally be able to breed and give birth to a fertile new "child." However, given that they are not of the same species, they cannot do such a thing, which is why this scientist classified them that way.</span>

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).

Micah has straight hair. If he is homozygous for the gene that determines straight hair, what is true of his parents?
alexgriva [62]

Answer:

They have contributed same allele for straight hair.

Explanation:

There are two conditions homozygous and heterozygous. In homozygous conditions both the allele of a particular gene is same in an offspring which means the offspring got two same alleles from its parent for a particular gene and if an offspring is heterozygous for a gene that suggests that the parent has contributed two different alleles for that gene in the offspring.

So If Micah is homozygous for straight hair then it can be concluded that his parents have contributed two same alleles for straight hair genes.
