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.

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.

I miss him and a great friend of mine, my friend was real and not made of plastic, I couldn't hang with my brothers since they had friends over and my younger sister was at her friends house so, he would hangout with me, besides my brother he was my Angel and someone I never wanted to leave me, but he moved.

1. Why do you think hate crimes have not been reported by authorities?

2. If you could enact a law that would reduce racism and hate, what would it be?

Answers

Answer:

1. Because the authorities might not recognize them as hate crimes. Not all crimes are considered hate crimes and sometimes it's difficult to tell unless it was explicitly stated that the person who committed the hate crime did it as a hate crime.

2. I would have one to make sure all people are treated equally by the authorities. To make sure the crimes are actually investigated, and people are properly detained fairly. And to promote equalness above all because we are all mortal and not one of us is more special than the other. We all came in the game the same way we'll leave it the same way to.
