Which role do gametes play in reproduction?
Lesechka [4]
<span>C. Gametes are the sex cells, and each (sperm and ovum) contain half of the parent's genetic material. These cells will fuse to produce a zygote, which will usually contain the full number of genes required by an organism to live. If there is a chromosomal abnormality, such as a gamete with an extra chromosome, the offspring can either die in development or sometimes be born with physiological and/or developmental difficulties. An example of this phenomenon is trisomy 21, also known as Down Syndrome, in which the 21st chromosome bears 3 copies instead of the regular 2.</span>

When egg white is heated, it hardens and is opaque. This cooking process cannot be reversed, but hard-boiled egg white can be di
marshall27 [118]

Answer:

Generally proteins are denatured at high temperature.Therefore when  the egg is hard boiled they are denatured since eggs are protein,  the 3-dimensional  structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the  orderly arrangements of  disulphide bonds in proteins  are disrupted , which  results in the formation of inter chains bonds among   disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption  and formation of  a macro molecule.

However,   the  addition of reducing agent ,  breaks the covalent disulphide bonds.   While detergent breaks the interchain bonds among the disulphide bonds.  (The noncovalent bonds),These combined effects untangled the  mesh networks of polypeptides formed, and reduces the hardened nature,

Bees are common pollinators, and many commercially grown crops that we eat depend on bee pollination Bees' eyesight allows them
nadya68 [22]

Adaptations such as keen eyesight and ability to visualize colors allows the bees to find food while increasing the plants chances of pollination.

<h3>What are adaptations?</h3>

Adaptation refers to the special features an organism possess that enhances its chances of survival in its environment.

The adaptations in bees such as eye structure help them to easily locate flowers to obtain nectar.

The plants themselves are benefited as they can easily get pollinated by the bees.

Therefore, adaptations such as keen eyesight and ability to visualize colors allows the bees to find food while increasing the plants chances of pollination.
