Answer:

I'd say true

Explanation:

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.

Answer:

False

Explanation:

As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.

The metabolically active and growing phase of endospore forming bacteria is called the?

Paraphin [41]

The metabolically active and growing phase of endospore-forming bacteria is called the vegetative cell.

In bacteria, vegetative cells are ordinary living cells that are produced as a result of asexual reproduction.

Endospores consist of cytoplasm and DNA genome in bacteria and their formation is beneficial in many ways such as providing resistance against heat, adverse external conditions, and harmful radiation.

To put it simply, the vegetative cell is a restive stage of endospore bacteria that provides protection against harsh environments during the life cycle of bacteria by forming a protective layer.

What would happen to a sample of your red blood cells if they were placed in a hypotonic solution?

timofeeve [1]

Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm)

Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up.

The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC.

As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.

Compare and contrast genetic drift, bottlenecks and founder effect?

Pani-rosa [81]

The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful,Genetic drift can cause big losses of genetic variation for small populations, and A founder effect is an EVOLUTIONARY PROCESS THAT RESULTS FROM A FOUNDING EVENT. They are all similar because they all similar because they all effect result in a small population with a subset of the genetic diversity of the original population.

Which type of mutation results from the insertion or deletion of a nucletide into the gene?.

Artyom0805 [142]

Frameshift Mutation

A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases.

Thanks!
