The sodium - potassium pump usually pumps
ololo11 [35]

<u>Answer</u>:

Potassium inside the cell and sodium out of the cell

<u>Explanation</u>:

The presence of the pump can be seen in plasma membrane of the animal cell. Which can be followed by the ATP, this pump pushes sodium and potassium in completely opposite direction that can be said as against the concentration gradient. In one cycle of this pump, two potassium are ingested inside the cell and three sodium are taken out from the cell. Due to  more number of negatively charged proteins inside the cell, potassium ion contains more positive charge so pushed inside the cell. The potassium  is pumped through the channels.

What is the structure not present in early elephants?
Alexus [3.1K]
<span>It is a common misconception that elephants existed the same time as the dinosaurs did when in fact they have evolved 3 or 5 million years after these creatures.

The tusks of the elephant would probably be the structure not present in early elephants. It is only through evolution that these tusks grew. Some scientists have hypothesized that these tusks develop from the elephants' incisors.

Which statement best describes human eye color?
PtichkaEL [24]

Answer:

The most appropriate answer would be option 2.

In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.

A set of 15 genes is responsible for the color of the eyes. Two genes out of these 15 are OCA2 and HERC2 which are present on chromosome 15.

Thus we can conclude that eye colour is polygenic trait which does not follow Mendelian genetics.
