Answer:
At least give some answers to go by, anyway, if the evidence is not yet proven then nothing, if it is proven to be true(whatever it is) it would make us change the current model to support this new evidence.
Explanation:
Don't expect a perfect answer, I haven't done the question to know the answer choices, so this is all I can presume. and if somebody comes in here and pastes the answer from A.P.E.X without stating that they copied it I am going lose my mind.
how is the structure of a leaf optimized for photosynthesis
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.

Describe how the diaphragm and the rib cage and lungs move during inhalation and
exhalation.
this is science pls help
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.
we inhale o2 and we exhale co2. carbon dioxide is produced __________.
Compare and contrast between transportation in human ànd plants.
Why transport in human is more effective than that in plants
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.

the digestive system of most animals is lined with cells through which nutrients are absorbed. what is the embryonic origin of these cells?
Answer:
Further breakdown of food takes place in the small intestine where enzymes produced by the liver, the small intestine, and the pancreas continue the process of digestion. The nutrients are absorbed into the bloodstream across the epithelial cells lining the walls of the small intestines.What is the importance of sea-floor spreading?

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