Answer:
Drag
Explanation:
Drag is a force caused by air that slows objects down
Friction is a major force that slows the object down, air resistance is a type of frictional force.
What is air resistance?Air resistance is a kind of frictional force that slows down an object from moving in a particular direction.
During the movement an object has a particular speed for movement, speed depends on how friction works, more friction slows the speed of an object a low friction allows the object to at a particular speed.
Air is a mixture of gases and particles in the atmosphere, these particles create a force during the movement of an object in the air, and these forces decide the actual speed of object movement.
Therefore air resistance is a force that slows the object.

how is the mitochondrial DNA (mtDNA) transferred from generation to generation.
Answer:
maternal mtDNA
Explanation:
While nothing but the haploid nucleus remains of the sperm during fertilisation, the ovum still has its mitochondria and other organelles. Mitochondria are capable of division and will divide according to cell's needs.
So it is the maternal mtDNa that gets passed on. Spontaneous mutations can happen at any point ofcourse and get passed on in the same way.

What statement is true of channel and carrier proteins?
A. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.
B. Channel and carrier proteins always move substances from the side of the membrane with the lowest concentration to the side with the highest concentration.
C. Channel proteins undergo a shape change, while carrier proteins do not.
Answer:
A
Explanation:
Channel and carrier proteins are both considered facilitated diffusion. We also know that materials do not like to go against the concentration gradient so we can eliminate B.

The only type of human cell that is never replaced is ___. *
Answer:
The only type of human cell that is never replaced is Nerve cells.
Hope this helps you. Do mark me as brainliest.
The only type of human cell that is never replaced is nerve cell.
What is a nerve cell?Neurons are in charge of receiving sensory input from the outside world, sending action potentials to our muscles, and transforming and relaying electrical signals at every step in the process.
The nerve cell is the basic unit of communication in the nervous system (neuron). The cell body, a major branching fiber (axon), and numerous smaller branching fibers comprise each nerve cell (dendrites).
They do not divide in any way. There are only two exceptions to this rule: only two specific areas of the brain can produce new neurons. However, for the most part, the brain is unable to replenish dead neurons.
Thus, nerve cells are the ones that never gets replaced after getting injured.

Edrophonium is a drug the blocks cholinesterase from breaking down acetylcholine in the muscles. Why does this improve Annie's muscle function?
Answer:
Edrophonium is a drug used for the treatment of myasthenia gravis, a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness, which results from antibodies that block or destroy nicotinic receptors at the junction between the nerve and muscle. By blocking cholinesterase, an enzyme which demolish acetylcholine, it increases the amount of acetylcholine in the neuromuscular junction improving the muscle weakness
It improves Annie's muscle function as a result of the acetylcholine not
being able to be broken down in the muscles.
Acetylcholine is a neurotransmitter that sends signals to the brain and other
parts of the body in the activation of the skeletal muscles.
The drug known as Edrophonium which blocks cholinesterase breaking
down acetylcholine in the muscles will thereby lead to more presence of
acetylcholine and a corresponding increase in the muscle functions.

Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.

Tim does not need to factor his amino acid consumption into the total protein intake because they are components of protein, not full protein
Answer:
Yes.
Explanation:
Yes, amino acid can not be factor or broken down because it is the smallest unit of proteins. Proteins are made up of about 20 small amino acids. Proteins can be factor into amino acids but amino acids can't be factor into proteins because proteins are made up of amino acids but the amino acids does not formed from proteins so that's why Tim does not factor his amino acid into total protein.
