Gases like oxygen and carbon dioxide move across cell membranes using what?
Answer:
simple diffusion
Explanation:
It uses no energy to move across the plasma (cell) membrane.
Describe how the plasma membrane controls what goes into and comes out of a cell
Answer:
The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. Passive transport does not require energy molecules and happens when a funnel opens in the membrane, letting molecules flow through.

Explanation:
we foumd out that was a thing. like red hair is recessive. black hair is dominant. that kind of thing.
Answer:

which of the following is a complementary base pair ?
A . guanine - thymine
B . guanine - guanine
C . adenine - cytosine
D . guanine - cytosine
Answer:
D is the anwser
Explanation:
I took the test and the answer was Guanine and cytosine!
A complementary base pair in DNA is guanine-cytosine (Option C).
The deoxyribonucleic acid (DNA) molecule is a double helix composed of two long (polynucleotide) opposite chains that are held together by hydrogen bonds.
In DNA, there are four types of nucleotides, each having one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).
According to the base pair rules, Guanine always pairs with Cytosine by three hydrogen bonds, whereas Thymine always pairs with Adenine by two hydrogen bonds.
In conclusion, a complementary base pair in DNA is guanine-cytosine (Option C).
