Choose the phrase that completes the passage. When Harrison is walking home from work, he is accosted by a group of teens. Harri
In-s [12.5K]

Answer:

This is an example of Harrison's central nervous system working closely with his autonomic nervous system to give him energy and awareness to escape.

Explanation:

Harrison interprets the presence of the group of teenagers as an imminent danger and so he is on the run, which corresponds to a set of reactions that are triggered in the human body when a danger is around. At this point, the central nervous system and the subtonic nervous system are working together to get the adrenaline in Harrison's body to rise to a level that allows him to escape the group of teenagers. The central nervous system was then responsible for receiving and processing information that indicates to Harrison that he may be in danger.  On the other hand, the autonomic nervous system is responsible for regulating the body's involuntary responses, being responsible for controlling various vital functions and at this time for the release of adrenaline in response to the dangerous situation.

makkiz [27]

Answer:

Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.

Explanation:

Golgi apparatus has a flat membrane disk in varies in number in stack, the number can be in between 3 to 20, however six is found in most of them. Cisternae can be separated in four classes cis, medial, trans, and TGN.

Proteins that come from the endoplasmic reticulum in cis type of cisternae after passed through cis to cis and move the protein in order to add or remove sugars to protein.

Thus, the correct answer is - Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively. Allele 1 has a selection coe
Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q  = 0.3   ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s    ( where s is the selection coefficient)

= 1 - 0.2

= 0.8
