Answer:

B. strand separation of the double stranded DNA occurs.

Explanation:

When mammalian DNA is heated to about 95°C, the hydrogen bonds between the A-T and G-C base pairs in the DNA double strand will break apart, unwinding the double-stranded DNA.

Which process takes CO2 out of the atmosphere
mihalych1998 [28]

Answer:

Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen.

Explanation:

Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen. By respiration, O2 is removed from the atmosphere and replaced with CO2. However, these processes are not balanced. Some organic matter is not oxidized. (I'm very sorry if I'm wrong but I believe it's that)

29. What conditions would cause a molecule to diffuse from the outside of the structure shown to the inside?
dmitriy555 [2]

Answer:

The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.

Explanation:

The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.

<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated .

The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.
