List the events of the sodium potassium pump in the correct sequence, starting at the TOP.
marishachu [46]

<u>Answer</u>:

<em>Sodium potassium pump works by following several steps. </em>

<u>Explanation</u>:

<em>1. Carrier protein binds three molecules of Na+ </em>

<em>2. ATP is split, phosphate bonds to carrier. </em>

<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell. </em>

<em>4. Carrier binds two molecules of K </em>

<em>5. Phosphate is released. </em>

<em>6. Potassium is released inside the cell </em>

Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.

It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.

<em>Thus it is an active transport mechanism. </em>

A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR).
igomit [66]
So I don’t see answer choices here, but your answer is 50% of the offspring will be homozygous dominant with RR, and 100% of them will carry a homozygous dominant gene of Rr

If you take the two sets and put them into a punnett square, it would look like this (image attached):

When the two sets of alleles are crossed, you would end up with half of your pairs being fully dominant (RR), and the other half being dominant while containing a recessive gene (Rr). Since there’s only one recessive gene in these pairs, it gets overridden and the pair itself is dominant.

So your answer is 50% will be homozygous dominant with RR!
