Answer:
Acetylocholine
Explanation:
Acetylocholine is a neurotransmitter and a neuromoderator.
It is a chemical that that is released by nerves or neurons and has functions in enabling muscle contraction,activates pain responses and plays an important role in learning and memory processes in the hippocampus.
Alzheimer disease is characterized with loss of memory.
Research suggests that the decline in memory is due to a deficiency in Acetylocholine in an individual's brain

Explanation:
Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.
Answer:
D
Explanation:
Conjugation is one of the processes employed by bacteria cells for genetic exchange. It involves the transfer of genetic material from one bacterium (donor) to another bacterium (recepient) via direct contact.
The donor bacterium carries a DNA sequence called Fertility factor or F-factor, which allows it to synthesize a tube-like stucture known as pilus (plural - pili). The pili that performs this function in bacteria is called CONJUGATE PILI. The pilus draws the mating pair (donor& recepient cell) close to each other to form a wall-wall contact triggering the formation of a mating bridge. This bridge enables the transfer of genetic material, usually in form of a plasmid (a small circular piece of DNA capable of replication independently of the bacterial chromosome).
In bacterial conjugation, the process involves a small portion of the genome of the donor cell getting inculcated into the complete genome of the recepient cell. Hence, conjugation is of immense importance to bacteria, as it is an avenue to confer certain genes e.g. antibiotic-resistant genes.
