PLEASE HELPPPPP I WILL GIVE BRAINLIEST
Nostrana [21]

Answer:

The correct answer is - because 3×3×3 has the highest Surface area to volume ratio, diffusion in and out of the cell would be faster.

Explanation:

It is known that if the size of a sphere or cell increases, the volume is a cube, and the surface area is squared therefore volume increases faster than the surface area. If the volume is more and the surface area is less than diffusion will be less effective. diffusion takes longer and is less effective.

The decrease in the surface-to-volume ratio leads to diffusion to get less efficient. The Surface-to-volume ratio of a sphere decreases as the sphere gets bigger.

Cardiac muscle cells are striated like skeletal muscles but their contractions are
professor190 [17]

Answer:

True

Explanation:

Cardiac muscle cells appear striated. However, they are involuntary, unlike skeletal muscle cells, because they contract outside of human control. For example, you do not have to think about contracting your heart muscles as the already contract for you. On the other hand, skeletal muscle cells are controlled by humans as they decide which body movement to perform, such as walking or pointing.

Why do so many (~30%) gorilla babies die within the first few months of their lives?
katrin2010 [14]

(30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

What is inherited disease?

Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.

Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.

Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.
