Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. ... Each resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell.

You are an expert paleontologist reviewing the work of Professor Bonefinder, who recently discovered the remains of a primate fo

sergeinik [125]

Answer:

The professor Bonefinder has made a mistake.

Explanation:

I't is true the Hominoid had a long snout, a large orbits that are partially enclosed, but they have no tail. This point is really critical because the morphology of an species is really important. The taxonomists use the information that morphology gave for many years to identify species, nowadays with molecular techniques some of those species are pulled apart, but the important matter is that hominoids had no tail.

So the professor Bonefinder analysis is incorrect because the hominoids have no tail.

Cells must use energy to move a substance against a concentration gradient i.e., from a compartment with a low concentration of

garik1379 [7]

Answer:

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

Explanation:

In general the concentration of sodium ion is higher outside the cell in the extracellular fluid and the concentration of potassium ion is higher inside the cell.

During an active transport, a cell uses energy to move molecules against the gradient as a part of primary active transport. In the secondary active transport, the molecules move as per the electrochemical gradient established by the primary active transport.

In primary active transport, sodium ion moves out of the cell and potassium ion moves into the cell through the assistance of sodium potassium pump. In order to maintain the stability, calcium ion from the sarcoplasmic reticulum is pumped out of the cell

Hence , the correct answers are

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.
