Answer:

B

Explanation:

A nucleosome is a section of DNA that is wrapped around a core of proteins. Inside the nucleus, DNA forms a complex with proteins called chromatin, which allows the DNA to be condensed into a smaller volume. When the chromatin is extended and viewed under a microscope, the structure resembles beads on a string. Each of these tiny beads is a called a nucleosome and has a diameter of approximately 11 nm. The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4. The chain of nucleosomes is then compacted further and forms a highly organized complex of DNA and protein called a chromosome.

PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

Answer:

Animal cells tend to do best in an isotonic environment, plant cells tend to do best in

a hypotonic environment. This is demonstrated in the attached PDF.

Explanation:

A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst)  when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.

I hope this helps. If not I am really sorry!

What type of communication coordinates actions between neighboring cells?
bija089 [108]

Answer: A. Chemical signal

Explanation:

Chemical signal is the type of communication which coordinates actions between neighboring cells .

This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma  membrane and  changes  are brought about within the cell in response to this message.
