Answer: A

Explanation:

Our universe was born from the Big Bang about 13.5 billion years ago. ... Our solar system began forming about 4.6 billion years ago within a concentration of interstellar dust and hydrogen gas called a molecular cloud. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center.

A science club has 16 members. How many ways can a president, a vice president, and a treasurer be selected from the members?
boyakko [2]

Answer:

The answer would be D. 3,360

Explanation:

The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.

In response to a stimulus, the membrane slowly depolarizes until the membrane potential reaches a particular value, called thres
Leni [432]

Answer:

The Question is incomplete. Here should be the complete question.

Based on what you have learned about how cells ensure that proteins end up in the right place (Chapter 7), what type of signal would you expect to be exposed on a cytosolic receptor after a steroid hormone changes the receptor's conformation?

Amino acids required for transport through the nuclear pore complex

Initiating an action potential

Under most circumstances, once an axon's membrane potential reaches threshold (about -55 mV in mammals), an action potential is automatically triggered. The graph below shows the changes in membrane potential that occur in an axon membrane that is initially at resting potential.

In response to a stimulus, the membrane slowly depolarizes until the membrane potential reaches a particular value, called threshold. At threshold, a rapid depolarization of the membrane occurs and an action potential is initiated.

Drag the labels onto the flowchart to show the sequence of events that occurs once

the membrane potential

-1. membrane potential reaches threshold

-2. Na+ ions rush into the cell

-3. membrane potential rises (depolarizes) rapidly

-4. many Na+ voltage-gated channels open

The ANSWER WILL SURELY BE

membrane potential reaches threshold ---> many Na+ voltage-gated channels open ---> Na+ ions rush into the cell ---> membrane potential rises (depolarizes) rapidly

(1--->4--->2--->3)
