<span>The dominant motion in the universe is the smooth expansion known as Hubble's Law. In 1929, Hubble estimated the value of the expansion factor, now called the Hubble constant, to be about 500 km/sec/Mpc.</span>

What are the three types of osmosis? What happens during each phase?

Vanyuwa [196]

An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .

A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.

A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.

In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t

Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² + 2pq+ q² = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = $\sqrt{0.35}$ = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.
