Which of the following is not a difference between mitosis and meiosis?

Which of the following statements about muscle is/are TRUE?

DanielleElmas [232]

Answer:

Option I

Explanation:

Muscles are able to use glucose, fatty acids and ketone bodies as a source of fuel. Option 2 is false as if glycogen degradation and synthesis rates are equivalent, there will be no net release of glucose of synthesis of glycogen which would be a 'waste' or resources in the muscles cells. Do note that this does not happen in a muscle cell as normally either one of the processes are dominant, not both at the same time. Option 3 is incorrect as muscles cells do not have glucagon receptors and hence cannot respond to glucagon nor perform gluconeogenesis (only happens in the liver). Glycogenolysis in the muscles are to supply energy to the muscles for movement, not release glucose to the bloodstream hence it will not respond to glucagon in the bloodstream.

Which parts are included in a scientific name? Select all that apply.

lorasvet [3.4K]

Answer:

Genus and species name

Explanation:

Scientific names are created to help decrease confusion in the naming process of animals and plants. The first part is the genus which is the origin of the organism and the second part is the species which is what identifies it as plant, animal, and other stuff.

Hope this helps :)

Human albinism is an autosomal recessive trait. Suppose that you find a village in the Andes where 1/4 of the population is albi

Aleks04 [339]

Answer:

500

Explanation:

According to the given information, the total number of albino people in the population= 1000/4 = 250.

Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.

The frequency of recessive allele (q) = square root of 0.25 = 0.5

Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5

Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%

Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500

if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it

Olenka [21]

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.

When a presynaptic cell sends information, a neurotransmitter is released.

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space <em>instead of binding to its receptor. </em>

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.
