B. An oak tree grows from the seed material in an acorn.
C. Water drips from underneath an oak tree leaf in the morning.
D. Sediment from an area where oak trees were cut down builds up alongside a stream
The example that demonstrates that all cells come from pre-existing cells is an oak tree grows from the seed material in an acorn (option B).
The cell theory is the scientific theory that all living organisms are made of cells as the smallest functional unit.
One of the components of the cell theory is that all cells come from already existing cells i.e. new cells form from cells that are already in existence in a process of reproduction.
The example of this is a tree that grow from a germinating seed. Hence, option B is correct.

b. Translation may not take place.
c. Future transcription will not take place.
d. Ribosomes may be destroyed.
I thought it was A, but again it was incorrect, Can someone help me find the correct answer and the reasoning behind it.
Answer:
b. Translation may not take place.
Explanation:
DNA transcription into RNA is the starting point for all phenotypic expression. As in replication, access to DNA is mediated by the interaction between proteins and certain regions strategically placed in relation to the segment to be transcribed; and it also requires helicases that denature the double strand to allow the "reading" of the nucleotide sequence by polymerases. But RNA polymerases, enzymes that perform transcription, use only one of the DNA strands as a template, allowing them to pair again at the end of the process; therefore, the end product of the transcription, or primary transcript, is a single-stranded messenger RNA molecule.
Although it is rare, messenger RNA can have errors. These errors are less harmful than the errors that occur in DNA, but they can prevent the translation from occurring later.

B. It prompts the kidneys to reabsorb more water into the bloodstream to dilute the salts.
C.
It inhibits the skin to sweat. This retains more water into the bloodstream to dilute the salts.
Antidiuretic hormone (ADH), also known as arginine vasopressin (AVP), is a hormone that regulates water balance in the body by managing how much water the kidneys reabsorb while filtering wastes from the blood. Option B is correct.
To dilute the salts, it causes the kidneys to reabsorb more water into the bloodstream.
The hormone ADH, also known as vasopressin, is generated in the hypothalamus and kept in the posterior pituitary gland. ADH is generated in reaction to excessive salt levels in the blood or low water levels in the blood. ADH then goes to the kidneys, where it interacts to receptors on collecting duct cells.
