Answer:

B. axon hillock

Explanation:

The axon hillock is the junction where the cyton connects with the axon. There is only one axon hillock in the neuron and it is a triangular depression of cell boy to the axon. The axons receives impulse from cyton carry to the different parts of the body. The axon hillock is also called initial segment. Because action potential starts here.

Myelin sheath is the cover or layer around the axon and helps in saltatory movement of impulse. The propagation of impulse is fast in myelinated neurons than the non-myelinated neurons.

The neurolemma is the neural membrane of the neurons. It is like the plasma membrane of the cell. The outer covering of neurons is called neurilemma.

Axon collateral is the end of the axon where axon terminals arise. They carry impulse and transmit to the synapse.

Which question will best help a student determine whether an organism is a member of Kingdom Archaebacteria or a member of Kingd

exis [7]

Answer:

Do the organism's colls have nuclei?

Explanation:

Protists represent eukaryotic organisms whose cells contain a nucleus and organelles delimited by membranes, whereas Archaea and Bacteria are unicellular prokaryotic organisms that lack a cell nucleus, in which the genetic material (chromosome) is localized in a part of the cytoplasm named nucleoid. Eukaryotic organisms include protists, animals, plants, fungi, and most algae. Most protists are unicellular, although there are species that are multicellular.

Prochlorobacteria are primitive, photosynthetic bacteria that are used in the manufacture of dairy products.

lesya692 [45]

Answer:

(b) - False

Explanation:

Prochlorophyte bacteria are photosynthesizers and have the same chlorophyll found in algae and vegetables, studies claim that these bacteria are the most abundant beings on the planet, accounting for half of all photosynthesis performed in the oceans.

Prochlorophyte bacteria can be divided into Prochloron, Prochlotrix and Prochlorococcus genera.

However, prochlorobacteria are not responsible for the production of dairy products, in which the most associated bacterial genera are Lactobacillus and Streptococcus. This last statement implies that alternative b is the correct one.
