Answer:

1 - some animals may fall into more than one living environment.  

2 - I would put a penguin in the water since they need it to survive even though they don't live in it all the time.   A number of birds that live by the ocean also have dual environments they need to survive

Explanation:

hope this helps

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)

Can someone help please?
sergij07 [2.7K]

uhm, though the graph doesn't match the problem, I remember doing this when I was in bio. If you are looking for the genome, it would be something along the lines of Gg, or GG (G=green dominant, g=yellow recessive)

I hope this is what you need!

Which parts of the nephron does adh act on to regulate water reabsorption?
Mashutka [201]

Distal Convoluted Tubule and Collecting Duct are parts of the nephron does ADH act on to regulate water reabsorption. ADH acts throughs G-protein coupled receptor in order to increase transcription and the insertion of Aquaporin–2 channels for the apical membrane of the CD and DCT cells. Therefore, the permeability of CD and DCT cells to the water increases.

A Distal Convoluted Tubule (DCT) is a short nephron segment, a portion of kidney nephron between Henle or macula densa and the collecting tubule loop. It plays an important role in regulating extracellular fluid volume and electrolyte homeostasis. In DCT, Sodium absorption occurs, which is mediated by the hormone aldosterone.
