why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?

Answers

Answer:

This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

What is the role of mitochondria in producing energy?

The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.

Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.

Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

Answers

Answer:

During inhalation, the diaphragm contracts and pulls downwards, the ribcage expands, allowing oxygen to be sucked in through negative pressure, which causes the lungs to inflate.

During exhalation, the diaphragm and ribcage relax, returning to their normal positions, allowing the oxygen out of the body, thus deflating the lungs.

Compare and contrast between transportation in human ànd plants.
Why transport in human is more effective than that in plants

Answers

Answer:

1)Plants do not have a circulatory system.

•Humans have a well defined circulatory system.

2)transportation in plants occurs through specialised tissue xylem and phloem.

•Transportation in humans occurs through a netwotk of blood vessels such as artery vein capillary.

3)In plants substances transported are water, minerals, sugars and amino acid.

•In humans substances transported are glucose, glycerol, minerals, vitamins, fatty acids, amino acids and hormones.

4)Transportation in plants in controlled by opening and closing of stomata.

•Transportation in humans is controlled by constriction or dilation of blood bessels.

-->■Transportation in humans is more effective than the plants because in humans there is a well defined circulatory system which is highly regulated.As transport occur through blood vessel , transportation can be regulated by dilation or constriction of blood vessel.But plant do not have such circulatory system.

how is the structure of a leaf optimized for photosynthesis

Answers

Answer:

- The upper epidermis of the leaf is transparent, allowing light to enter

- They have a large surface area to volume ratio, allowing more light to enter

The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.

What is responsible for photosynthesis to occur?

The mesophyll cell is responsible for photosynthesis occurs. The majority of the chloroplasts and the primary site of photosynthesis are located in the palisade layer. The area of storage and gas exchange is the airy, spongy layer. The stomata control the water and carbon dioxide equilibrium.

For gaseous exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which enable carbon dioxide to enter the leaf and oxygen to exit, they are well-equipped for photosynthesis.

Chloroplasts, which is known as the house the chlorophyll in plants, are where photosynthesis occurs. The thylakoid membrane, a third inner membrane that creates lengthy folds inside the chloroplast and is bordered by a double membrane, is present inside chloroplasts.

Therefore, The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.

as of may 2020, carbon dioxide levels have reached 417 parts per million. what level should they be at to have the world in a climate similar to that in which civilization first developed?

Answers

Given what we know about global carbon levels in the present and the past, we can confirm that in order to be at the level of early civilizations, the modern-day carbon level should be at 280 parts per million.

Global atmospheric carbon levels are measured in parts per million. What this means is that for every one million units of mass in the atmosphere, 280 of them were carbon. This means that in recent years, the global carbon levels in the atmosphere have doubled.

The primary cause of these increased carbon levels is industrial pollution. Chemicals are released into the atmosphere as a by-product of industrial processess. This began with a noticeable spike during the industrial revolution and has then increased without end.
