<h2><u>Heart and lungs:</u></h2>

The upper chamber of the heart is called atrium and lower chamber of the heart is called ventricles.

The blood circulation in the heart is basically under the functioning of three blood vessels namely:

<h3><u>Arteries: </u></h3>
  • They start with the aorta, the huge vein leaving the heart.
  • Veins divert oxygen-rich blood from the heart to the majority of the body's tissues.
  • They branch a few times, decreasing and littler as they convey blood more remote from the heart.
<h3><u>Capillaries: </u></h3>
  • These are little; flimsy blood vessels that associate the arteries and the veins.
  • Their dainty dividers permit oxygen, supplements, carbon dioxide, and other waste items to go to and from our organ's cells.
<h3><u>Veins: </u></h3>
  • These are the blood vessels that return blood to the heart; this blood needs (oxygen-poor) and is wealthy in waste items that are to be discharged or expelled from the body.
  • Veins become bigger and bigger as they draw nearer to the heart.
  • The unrivaled vena cava is the huge vein that brings blood from the head and arms to the heart, and the second rate vena cava brings blood from the mid-region and legs into the heart.

Answer:

Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!

Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.

Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.

The right answers are:

create two identical cells ==> mitosis

create four non-identical cells ==> meiosis

create haploid cells ==> meiosis

creates diploid cells ==> mitosis

occurs in all cels other tha gametes ==> mitosis

occurs in all cells related to sexual reproduction ==> meiosis

Glycogen reserves can release glucose for cellular respiration. glycogen reserves are typically found in?
avanturin [10]

Glycogen reserves can release glucose for cellular respiration. glycogen reserves are typically found in the muscles and liver.

  • The liver and muscles contain the body's "quick" source of energy, known as glycogen stores.
  • They go through further metabolism after being converted to glucose.
  • After that, glucose can be further digested to release energy both aerobically and anaerobically.

<h3>Glycogen reserves: what are they?</h3>
  • When the body doesn't need to consume the glucose for energy, the liver and muscles store it.
  • This kind of stored glucose, which is made up of many connected glucose molecules, is known as glycogen.

<h3>How long are glycogen reserves good for?</h3>
  • Utilizing the form, you can learn more about nutrition and glycogen.
  • But it's helpful to know that once glycogen stores are exhausted, it will take at least 48 hours to fully refill them.
  • This necessitates rest throughout the recovery period and a high-carbohydrate diet (60–70% of the energy must come from carbohydrates).

Please someone help me and yes it can be more then one answer but give me your best answer
Strike441 [17]

Answer:

????

Explanation:

None of those seem to be correct to me.

1. Observations are made using the five senses- sight, sound, touch, taste, and smell. So this is invalid.

2. Observations and experiments can both be done anywhere

3. See answer to 2

4. It's cut off? But observations can literally be as simple as looking at a stick and noting that it's brown, so from what I can read, it's invalid.
