Tim does not need to factor his amino acid consumption into the total protein intake because they are components of protein, not full protein

Answers

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.

Edrophonium​ is a drug the blocks cholinesterase from breaking down acetylcholine in the muscles. Why does this improve Annie's muscle function?

Answers

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.

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.

Explanation: just took this, these are the correct answers for MY quick check. could very well be different for yours. hope this helps though :)

The number of organisms exhibiting a phenotype variant near the lowest value is ; ( C ) Less than the number exhibiting a variant near the middle value.Kamara can assume that ; ( A ) Kamara mother must be either AB or B because blood types AB is considered codominant.The sample that is most likely to produce a normal distribution is ; ( A ) Grade 10-12,  Height Range 55 - 60 60 - 65 65 - 70 70 - 75 , Frequency 4 9 8 4.Various variants of a trait available to a gene are called ( A ) ; Alleles .The undercoat thickness in this population will likely ( B ); shift toward a thicker coat.

The wolves undercoat will grow towards been thicker in order to protect the wolves from extreme cold conditions posed by the winter and  this phenomena is called adaptation.

Blood types of offspring's are determined by the blood groups of both parents therefore if Kamara has a blood type AB his mother will mostly likely have either AB or B blood type.

Alleles are the different variants of a gene in living organisms but they are located at the same position on the chromosome.
