Which of the following are prokaryotic cells?

Tortoises found on the Galapagos Islands can have varied phenotypes. One of the variations in the phenotypes is with regard to

qwelly [4]

Answer: B:The drought decreased the grass and vegetation on the ground, leaving only vegetation on shrubs and trees above the ground. Natural selection selected for the tortoises with the domed shells and hoods.

How to seperate peanuts from sugar

Fantom [35]

Since the peanuts are so much bigger then granules of sugar, paper filter wouldn’t separate them sugar isn’t fine enough, there’s no magnet in either and stove wouldn’t do anything so it must be strainer

Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?

oee [108]

Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.

mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to the ribosomes of a cell, which are in charge of reading the code, one codon at a time, and chaining together the corresponding amino acids.

Pick one of anna's illnesses and explain all of the ways the illness affected three different body systems.

Rudik [331]

Heart disease affects the cardiovascular system by plaque building up on the artery walls narrowing them making it harder for blood to flow through which could lead to heart attack or probably stroke if the plaque blocks it entirely or maybe almost entirely.

Heart disease may also affect our nervous system for there is higher risk to stroke and it is due to limited flow of blood to the brain and may lead to heart failure which may happen with heart disease that puts the stress on the brain and nerves.

The digestive system is affected by heart disease that causes the system to not get the right amount of oxygen and the nutrients that it needs from the blood.

A retrovirus hijacks a cell's machinery to turn its rna into dna, which is then inserted into the cell's genome so viral protein

Doss [256]

No this virus does not follow the Central Dogma of Biology. The Central Dogma refers to the process involved in cellular replication starting from the replication of DNA, followed by transcription of DNA to RNA, and finally translation of RNA to proteins.

Viruses are special because they hijack cells and use the cell's own mechanisms in order for it replicate. Retroviruses are even more special because they go against the unidirectional flow of the Central Dogma. This is done with the use of their reverse transcriptase.
