During the cortical reaction, enzymes are released from vesicles in the oocyte. <span>The cortical reaction is a reaction for preventing polyspermy, the fusion of multiple sperm with one egg. It is a process which occurs during fertilization by the release of cortical granules from the egg. Cortical granules contain components which establish a permanent barrier to sperm entry.</span>
Answer: Individuals with bad traits die, because of survival of the fittest. Organisms who have better traits can reproduce and not be eaten the longest. So organisms who have bad genes will die quickly.
Answer:
they help to remove carbon dioxide through calcification
Explanation:
The correct answer would be that <u>they help to remove carbon dioxide through calcification</u>
<em>Shell-building marine creatures play important roles in regulating climate because they help to remove carbon dioxide from the environment through the process of calcification.</em>
Carbon dioxide is a major driver of climate change because the gas is among the greenhouse gases that absorb radiation from the sun thereby causing the warming of the planet. The more the carbon dioxide in the atmosphere, the more the amount of heat trapped and the more the increase in the global temperature. An increase in the global temperature causes the general climatic factors to become erratic.
Hence, the removal of carbon dioxide through the process of calcification is important for regulating climate change.
