why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?

Answers

Answer 1

Answer: Meiosis must occur at some point in the life cycle to prevent a doubling of chromosomes in each generation.

Explanation:

Answer 2

Meiosis has to take place at some point in the life cycle in order to stop the chromosome count from doubling with each new generation.

What is meiosis?

Meiosis is a specialised kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.

Meiosis results in the formation of four haploid daughter cells, each of which has the potential to differentiate into either sperm or egg cells in the future.

Well considering there aren't really any clouds at night it would be easier to navigate and tell time at night now during the day clouds would be in the way of the sun at SOME times which is probably one out of many struggles our human kind had back then.

Active listening is the process of getting ready to listen, paying attention to the verbal and nonverbal cues being used, and then reacting accordingly to demonstrate that you are paying close attention to what is being said. This kind of listening shows that the listener and speaker are on the same page.

Because it keeps us the positively connected with the discussion partner, active listening is crucial in communication. The other person feels heard and appreciated as a result as well. In any situation—at work, at home, or in social settings which this ability is the cornerstone of a successful dialogue.

Answer:

Position the infant facedown on your forearm

Explanation:

If I remember right this should be the correct answer

The actions needed to perform aid on a choking infant are:

A. Perform the procedure in a sitting position.

B. Position the infant face down on your forearm.

E. Begin chest compressions if the blockage does not clear.

What is Choking first aid for babies?

When anything gets lodged in the airway or the throat, choking occurs. This may prevent air from getting to the brain and deprive it of oxygen. Your infant will cough ineffectively and have difficulty breathing or loud breathing.

Young babies who swallow formula or breastmilk too quickly or who have too much mucus may choke.

A little enough item can obstruct your baby's airway. Small food fragments like nuts, grapes, beans, popcorn, hotdogs, or poorly chewed food are included in this. Common choking dangers include household items like buttons, marbles, coins, rubber balloons, and beads. Your toddler may choke on little toy pieces.

Turn the infant over so their back is to you and give up to five chest thrusts. Put two fingers right below their nipples in the center of their chest. Push downward firmly up to five times. Chest thrusts may move the obstruction by sucking the baby's lungs of air.

The correct answer is A, B, & E.
