<span>The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of </span>calcium ions.
Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.
<h2>Answer is "RuBisco"</h2>
Explanation:
- It contains high measures of fundamental amino acids, which makes it somewhat interesting among vegetable proteins. Because of its properties, RuBisCo is a generally excellent possibility for food applications. It can not exclusively be utilized as a protein source yet in addition as an emulsifier, frothing and gelling operator
- RuBisCO, and it is a type of protein, called an enzyme, that is involved in the Calvin cycle.An enzyme is a type of protein that makes reactions occur faster. For example, there is an enzyme in our body that helps transfer carbon dioxide from our cells to our blood. This reaction occurs 107 times faster with the enzyme
- Hence, the right answer for fill up the blanks is "RuBisco"
Answer:
D. predator population will decrease
Explanation:
If the population of prey species decreases then the competition between the predator population will increase and natural selection will act on them. So nature will select those individuals among predators who are more fit and adapted and less fit individuals will die.
So a few year after the predator population will decrease as there are not enough prey to support the large population of predators which was present when prey were abundant. Therefore the correct answer is D.
A . Human society is the best answer :)
A decrease in its sugar production.
