Answer:
The correct answer to fill in the blank is: glial cells.
Explanation:
<u>Glial cells are the other type of cells aside from neurons that are present in the nervous system. </u>
Glial cells are present both in the Central Nervous System and the Peripheral Nervous System, but in each of these anatomical divisions, the glial cells differ. For example, in the <u>Central Nervous System</u> there are oligodendrocytes (form myelin), astrocytes (provides nutrition for the neurons, maintains the ionic balance, repairs the tissue after damage, and forms the blood-brain barrier), ependymal cells (produces cerebrospinal fluid), and microglia (a specialized macrophage); while in the <u>Peripheral Nervous System</u> there are only Schwann cells (form myelin) and satellite cells (provide nutrients for the neurons).

The forces beneath the earths crust that makes volcano's erupt is Magma and the rocks around it, which both make its way up to a volcano by going through the cracks of the Earth's crust, when making their way up they release pressure that causes a volcano to erupt.
Answer: The regular progression of a species' replacement is known as ecological succession, or simply just succession.
Explanation: All ecosystems are not static, they change through time. All animals, plants, microorganisms, etc. (different species) create changes to their environments, but other factors such as climate change/weather, over-exploitation, human involvement, and other factors change an ecosystem.
The correct answer is B. This question relates to using a punnet square to determine the genotypes of the offspring. Two heterozygous parents expressing a polka-dot tale must have genotype Pp each.
Using a punnet square, this will produce 4 possible genotypes in equal probability:
PP - polka dot
Pp - polka dot
Pp - polka dot
pp - solid tale
Therefore there is a 75% change of getting polka dots in the offspring, and a 25% chance of solid tale.
A. is an incorrect answer because only 50% of offspring will be type Pp, another 25% will be expressing double dominant alleles for P as PP, which will still express polka dots.
