The answers would be (a.) a zygote is formed, (b.) a barrier to other sperm forms immediately and (c.) new genes are formed. The process of fertilization begins with the fusion of the ovum with a sperm that will lead into the formation of the zygote and will eventually result into the development of a embryo.

Answer:

The correct answers would be:

a a zygote is formed
b a barrier to other sperm forms immediately

Acrosomal and cortical reactions take place at the time of fertilization of egg and sperm.

Acrosomal reaction helps in penetrating the zona pellucida so that sperm nuclei can enter the oocyte.

Cortical reaction results in the hardening the zona pellucida which prevents the entry of any other sperm cell.

Post-fertilization, the oocyte completes its second meiotic division and matures into the ovum.

The pronucleus of the male moves towards the center of the oocyte in order to fuse with the pronucleus of the female. It results in the formation of a diploid zygote nucleus. It divides with the help of mitotic divisions and develops into the embryo.

Consider two enzyme reaction solutions. Solution 1 has a ratio of enzyme to substrate of 1:100. Solution 2 has a ratio of enzyme

Korvikt [17]

Answer: Solution 2 because the single substrate easily get transformed into products at the active site of any of the 100 enzymes.

Explanation:

Since Solution 1 has 1 enzyme to 100 substrate while Solution 2 has 100 enzyme to 1 substrate, catalysis of the single substrate to product will be greater in Solution 2 as the enzyme will compete to quickly transform the single substrate in its active site unlike solution 1 will 100 substrates taking more time.

Some people use paint to protect the outside of their houses. Why does a house painted a dark color get hotter than a house pain

Trava [24]

Answer:

Dark color absorb more photons and thus gets more hot

Explanation:

Dark color is dark b/c it absorbs different wavelengths of light (think about little photons of light vibrating slighting differently) .This means it absorbs a lot of photons which makes it warmer.

If a thing is white, that means it reflects all lights and absorbs none. Thus, since it does not absorb photons (little packets of energy which is light), the house does not get warm.
