Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.
What is a sound wave?A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.
The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.
These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.
Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

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.

Water, carbon dioxide, oxygen and some other substances can pass through the cell membrane because?
Answer:
Water, carbon dioxide,oxygen and some other substances can pass through the cell membrane because oxygen and carbon dioxide moves across the cell membranes from a simple diffusion a process that does not require any energy input and is driven by differences in concentration on the other side of the cell membrane.
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.

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.

c.) crossing over
d.) synapsis
Answer:
b.) nondisjunction......
A woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.
What do you mean by Chromosomes?Chromosomes may be defined as tiny, threadlike structures inside most cells of every organism, or living thing which carries the genetic information.
The presence of 3 X chromosomes indicates the condition of trisomy which arises as a result of non-disjunction.
When homologous chromosomes fail to separate at meiosis resulting in a germ cell containing 24 chromosomes rather than 23.
Therefore, a woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

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.
