Answer:

To view the mitochondria you will need a light microscope. The mitochobdria is to small to see with a light microscope. The organelles are found in tje cheeck of an onion cell bit are to small to see.

The membranes of both b cells and the cancer cells are largely composed of phospholipids. Explain how
iragen [17]
<h2>Answer:</h2><h2>when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell .</h2>

Explanation:

Cell membrane is composed of phospholipid bilayer . Cell membrane is hydrophilic at the surface of outside of the cell and inside surface of the cell thus both surface of cell membrane is a hydrophilic . Interiorly cell membrane is hydrophobic or nonpolar region because membrane composed of long fatty acid chain interiorly . Inner surface of cell membrane have no contact with water or polar molecules . When membrane binds to each other then the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell , while nonpolar parts of cell avoid water and create bilayer phospholipid where hydrophobic tails are in between the hydrophilic heads .

Cerebral Nuclei.

Explanation:

Cerebral nuclei refers to one of three components of the cerebrum. It is a composite structure of the end-brain defined on the basis of origin from the ventricular ridge of the embryonic Encephalon. It is a lusters of gray matter that contain neuron cell bodies and lie within masses of white matter.

Infer: Parrotfish rely on corals for protection and shelter. Look at the parrotfish population over time. Why did the parrotfish
Anna71 [15]

Answer:

Lack of shelter.

Explanation:

Although I cannot see the graph of the population over time, I am assuming it was exponentially rising and then began to decline. This is because the parrotfish were able to populate only until the species ran out of shelter. Once it ran out of shelter, the exposed fish began to die due to predators or the environment.

It may also be because of the drastic decline of living coral reefs. As coral reefs die, so do livable habitats for the parrotfish. As a result, the parrotfish decrease in population as fewer corals are available for the fish to live in.

6. Delete any base (between the READING FRAME, excluding the start and stop codons) and show the change in the amino acid sequen
kati45 [8]
This is the DNA. I'm going to only use the upper strand to demonstrate what this strand would code for before and after a single bp deletion (so write it as mRNA). I will also write it how it's easier to see this which is to split them up into the 3 base codon system. Note that you don't need to know the amino acid code - you use a table to find these.

ORIGINAL (mRNA on top, Amino Acid (AA) on bottom:

5'-AGC GGG AUG AGC GCA UGU GGC GCA UAA CUG-3'
    SER  GLY  MET SER ALA  CYS GLY ALA  STOP LEU 

Note that the protein would stop being made at the stop codon and the LEU wouldn't matter at the end...

Now, I will remove one bp...(I bolded it up top). Rewrite the mRNA and find the corresponding AA...

NEW
5'-AGC GGG AUG GCG CAU GTG GCG CAU AAC UG-3'
   SER  GLY  MET  ALA  HIS   VAL  ALA   HIS  ASN .....

Completely different amino acid sequence after the methionine (MET). The stop codon is gone...the protein would continue being translated until it reaches another stop codon...so not what was supposed to be made!
