Answer:

bipolar

Explanation:

Neurons are highly excitable cells that communicate with each other or with other effector cells, using basically electrical language. Most neurons have three regions responsible for specialized functions: cell body, dendrites, and axons.

Most neurons have several dendrites and one axon, so they are called multipolar. But there are also bipolar and pseudo unipolar neurons. In bipolar neurons, two extensions leave the cell body, one dendrite and one axon.

Mutations in ubiquitin lead to malfunction of what organelle in ALS that leads to buildup of mis-folded proteins?
sergiy2304 [10]

Answer:

Mitochondria.

Explanation:

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder in which the neuron died due to mutation in superoxide dismutase 1 gene. This disease is also known as Lou Gehrig's disease.

Mitochondria structure is disorganized in ALS. The ubiquitin protein mutation leads to the malfunctioning of mitochondria and misfolded proteins are made in the mitochondria.

Thus, the correct answer is option (a).

Explain how the inheritance pattern shown in figure 1 supports a role for chloroplast genes in the production of chlorphyll in t
Aloiza [94]

Answer:

Answer b) The result of the experiment identifies that the color of the egg donor branch (parent) prevailed and assigned the color of the offspring.

-The female parental branches that were pure green or pure white had children of pure green or pure white, respectively.

- The female parental branches that were variegated allow to obtain the three types of offspring.

It is evident that the chloroplast shows maternal inheritance.

The branch that is pure green will produce eggs with green chloroplasts that will give rise to a pure green offspring. Thus, a pure white branch will have offspring with ovules with an exclusive content of white chloroplasts and will give rise to a pure white offspring.

If a branch is variegated, it is combined, some with only functional chloroplasts, some with only non-functional chloroplasts, and some with a mixture of chloroplasts. All three types of cells can give rise to ovules, leading to green offspring, white offspring, and variegated offspring.
