In the slow block to polyspermy, sperm penetration releases an inflow of Ca2+, which in turn stimulates the cortical reaction.

<h3>What is cortical reaction?</h3>
  • A medium known as the cortical response, which is started after fertilization, stops polyspermy, or the union of several sperm with one egg.
  • The cortical response, which in numerous species serves as the top element of the slow block of polyspermy, gradationally forms a endless hedge to sperm entry in discrepancy to the rapid-fire block of polyspermy, which instantly but temporarily inhibits new sperm from fertilizing the egg.
  • This barrier is made up of the egg's plasma membrane and cortical granules, specialized secretory vesicles found in the cortex (behind the plasma membrane) of the egg.
<h3>What follows the cortical response?</h3>
  • Cortical granules (CG), a type of specific organelle in the egg, release their contents into the perivitelline region after sperm and egg fuse (cortical response), making the zona pellucida resistant to sperm adherence and penetration.

What can be a benefit of using interviews to select employees to hire?
AlexFokin [52]

Answer:

B. Accurate prediction of honesty

Explanation:

Interviews are one of the most effective tools that human resource managers use to  determine if a candidate is a match or not for a specific job. Flexibility is the key word here.  That allows both the candidate and the interviewer, the possibility of understanding what are  the skills needed for a certain job and if the candidate possesses them. When someone  answers a test, you can tell if the candidate knows about the subject or not, but when he/she is interviewed, you can ask for more detail and examples that help clarify the candidate's  ideas, expectations and capabilities.  E.g. a candidate states that he/she knows how to use WordPress very well, and the interviewer can ask him/her about specific tasks to verify if that is true.

netineya [11]

Answer:

The answer is option B) The Delphi technique is a useful way to gather opinions from experts who desire anonymity.

Explanation:

The Delphi method seeks to collate opinions from a diverse set of experts, and it can be done without having to bring everyone together for a physical meeting.

Since the responses of the participants are anonymous, individual panelists don't have to worry about the consequences of their opinions.

Consensus takes time since opinions are carefully analyzed, making the method very effective.

It is an exclusive process used to arrive at a group opinion or decision by surveying a panel of experts.

Experts respond to several rounds of questionnaires, and the responses are aggregated and shared with the group after each round.

The experts can adjust their answer each round, based on how they interpret the group response provided to them to assess.

The ultimate result is meant to be a true consensus of what the group thinks whilst retaining the anonymity of the respondents.
