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.

Answers

Answer:

The Answer is protein.

Proteins help your body build new cells, repair old cells, create hormones and enzymes, and Kama your immune system healthy. if you don't have enough protein, your body takes longer to recover from illness and you're most likely to get sick in the 1st place. I hope this answers your question, and have a great rest of your day!

All of the nutritional classes play a role in absorbing vitamins and sustaining the immune system, but proteins are particularly important for these functions, as mentioned in the third option.

What is the immune system?

Proteins are essential for the production of antibodies, which are molecules that help the body fight off infections and diseases, and they are also involved in the production of enzymes, which facilitate the absorption and metabolism of vitamins and other nutrients. Some vitamins, such as vitamin C and vitamin E, are antioxidants that help protect the body against damage from free radicals, which can contribute to chronic diseases like cancer and heart disease. Fats also play a role in vitamin absorption, as many vitamins are fat-soluble.

Hence, proteins are particularly important for these functions, as mentioned in the third option.

Which of the following should you NOT use to put out a chemical fire?
A.
Salt
B.
Water
C.
Sand
D.
Baking soda

Answers

Answer:

B. Water

Explanation:

A: Salt

Salt disperses heat and minimizes oxygen supply to a fire. This is especially useful if you experience a grease fire on or around the oven. Salt is also one of the main ingredients found in fire extinguishers.

Total Fire Group has a list of other things that can put out a fire

B: Water

Class B fires are made up of flammable liquids. If you were to throw water on a Class B fire, you might very well remove the heat and extinguish the fire but you would be equally likely to cause the flammable liquid to spray all over the place while it is on fire.

Firefighter Inside has an amazing article on the classes of fire, how to put them out, and why certain things (like water) can't be used to put out certain types of fires.

C: Sand

Sand suffocates the fire getting rid of the oxygen supply to the fire. and when the fire has no more oxygen it goes out.

Hunker has an article on how to put out a fire with a bucket of sand

D: Baking soda

Baking soda is good for putting out small fire cause the powder suffocates it and the bicarbonate in baking soda creates a chemical reaction when it gets hot enough that it starts to produce carbon dioxide, carbon dioxide removes oxygen from the fire causing the fire to go out.

Firefighter Now has a better and more detailed explanation on baking soda.

Answer:

Many drugs are broken down (metabolized) with the help of a vital enzyme called CYP3A4 in the small intestine. Grapefruit juice can block the action of intestinal CYP3A4, so instead of being metabolized, more of the drug enters the blood and stays in the body longer. The result: too much drug in your body.
