Answer:

Major Organs of The Human Body

Explanation:

Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver and lungs. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones.

1. heart

The heart is at the center of your circulatory system, which is a network of blood vessels that delivers blood to every part of your body. Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly.

2.Brain

The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.

3. kidneys

Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium—in your blood.

4.liver

All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

5. lungs

Every cell in your body needs oxygen in order to live. The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried through your body.

Why are NADH and FADH2 necessities in the electron transport chain?(1 point)

wolverine [178]

NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.

NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.

Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.

Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.

yulyashka [42]

number 8 is b because when you eat plants or animals, it get transfred to glucose which is then transfered to atp. Think about it this way, when you are sick, you dont just go outside in the sun to recharge and then you suddenly get better, and energy, you have to rest and eat certain foods that will restore your ATP levles.

How is plant cell cytokinesis different from animal cell cytokinesis?

denis-greek [22]

Answer:

Explanation:

Cytokinesis, which is the division of a cell's cytoplasmic content, is the final step of cell division. After which the genetic material of a cell duplicates, they move towards opposite directions in the cell. The cytoplasm of the original cell halves itself equally for the two resulting cells. Though both animal cells and plant cells go through cytokinesis, they undergo it differently due to the presence of cell wall in addition to the cell membrane in plant cells.

In plant cells, cytokinesis mainly involves the formation of a CELL PLATE at the equator of the parent cell that will soon divide into two. The cell plate, which is the future doubled cell wall that will become separated into two cells, divides the cytoplasm.

In animal cells, cytokinesis occurs in a more complex manner. A fissure called CLEAVAGE FURROW develops by the formation and contraction of the CONTRACTILE RING, which is present beneath the parental's cell membrane and made up of actin filaments. The created furrow grows deeper (as the actin ring contracts) between the two resulting cells until they meet the membrane and pinch off (inwardly), separating from one another. Hence, resulting in two separate daughter cells.

The two most basic steps of dna replication are

Shkiper50 [21]

Explanation:

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
