Answer: C. Algae
because it is the right answer
Answer: ONLY CERTAIN SUBSTANCES CAN PASS THROUGH IT
Explanation:
1 only gases and water can pass through it.
2 substances need permission to pass through it.
3 only certain substances can pass through it.
4 substances need carrier molecules to pass through it.
5 ATP is always needed to move molecules across the plasma membrane.
The reason for this is because it is closer to water, therefor they have more events that could happen. Also there is a lot of weathering, erosion, and deposition which makes the gulf coast prairies and marshes more susceptible to changes.
I hope this helps!
Myocardium
<span>The heart has
four chambers, four valves. It is composed of cardiac muscles which all
in all pumps blood throughout the human body through the blood vessels.
When something gets injured around the heart, well it will
automatically, in high possibility stop functioning. Take not of the
valves and the most important is the sinoatrial node which is the pace
maker of the heart. It is what triggers the heart to pump itself and the
valves then function and the blood travels and then gets cleansed out
of carbon dioxide in the alveoli.<span> </span></span>
Answer:
Extension
Explanation:
Polymerase chain reaction is given by Kary Mullis and it contains three steps denaturation, annealing, and extension. In denaturation, the temperature is raised to 96° c so that the DNA can denature.
In annealing, the temperature gets reduced to 55°c so that the primer can bind to the complementary sequence. In extension, Taq polymerase is used to extend the new strand.
This enzyme is isolated from thermophilic bacteria and the temperature here is raised to 72°c so that the enzyme can extend the primer and make the complementary strand. So the right answer is extension.
