Answer:

a. deterioration of neurons that produce the neurotransmitter acetylcholine.

Explanation:

Alzheimer's disease -  

It is a disease associated with memory , it is a type of dementia .

The initial stages of the disease is the remember new things , the day to day task becomes very difficult with time .

During this disease the neurons get deteriorated day by day , which are responsible to produce the acetylcholine .

Hence , the correct statement about Alzheimer's disease is ( a ) .

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here

Describe one way in which ribosomes interact with organelles. How would having a larger number of ribosomes benefit a cell? In y
tino4ka555 [31]

Answer:

Ribosomes are the machinery of protein synthesis in the cell. They are associated with different organelle of the cell. They are also found free-floating in the cytoplasm of the cell.

The organelle which ribosomes interact are plasma membrane in prokaryotes and endoplasmic reticulum(ER) in eukaryotic cell. Ribosomes are present on the surface of the ER and helps in protein synthesis in the ER. In prokaryotes, there is no ER so it is associated with plasma membrane and perform protein synthesis.

The specialized function of ribosome is to perform protein synthesis and these proteins are necessary for cell because protein are important to make enzymes that regulate the metabolism of the cell. So if protein synthesis stops cell will not able to perform important metabolic activities to survive and it will die.

Having a large number of ribosomes benefits cells because it fastens the protein synthesis process in the cell. So large amount of protein can be produced in less time.
