Muscle cells would contain a high number ofA. lysosomes. B. mitochondria. C. mRNA. D. Golgi bodies.
Answers
Answer 1
Answer:
The muscle is a soft tissue found in most animals. The cells in themuscle contain protein that produces a contraction that changes both the lengthand shape of the cell. They are responsible for the movement it produces in thehuman body. There are three types of muscle cell: skeletal, cardiac and smoothmuscle. Cardiac muscle contains excess amounts of mitochondria and myoglobin. Themyoglobin is responsible for the red color of the muscle. The answer is letterB.

Why might a blood cell have a different shape than a muscle cell
Answers
Blood cells carry oxygen to the rest of the cells in the body, and hemoglobin can help it do so. But in order for the hemoglobin to be effective enough, the blood cell has to be a certain kind of shape.
What happens during interphase?
Answers
the cell prepares for mitosis
the resting phase between successive mitosis divisions of a cell,basically the mother cell is resting there.

When you consider evolution, then you have to take into account where all life came from...the Ocean. Specifically micro-organisms in the ocean, they've existed for tens of Billions of years but land organisms around 5 billion years and that's to do with retreating tides etc. So from bacteria a single cell organism you make your way to minor complex organisms with the basic of physiological furniture and that's the 'digestive tract' and these guys are basically worms. Then quite a few million stages after that are the insects, as they improve upon just having only an advanced digestive tract to include other higher ordered functions as well adaptive mechanisms such as flight. But life is more diverse than just one track so it branched off before land dwelling and more than likely we as a species were developed in the ocean as multi-functioning organ-ed fish then onto land as res-pirating fish (such as lung fish, the first example of amphibians) then to higher order amphibians such as salamander types. Of course much of the stages proposed by Darwinian evolution are speculative so you decide :D ik this answer is long but its kinda hard to explain in one short sentence XD
What's so the "Central dogma" or sequence of information flow in Turing genes into proteins?
Answers
Basically it involves translations: Once you have your mRNA (which now only has exons) it then binds with rRNA (ribosomal RNA) It reads a start codon, and then the tRNA reads a complimentary anticodon which codes for a specific amino acid. Essentially the amino acids then interact elongate, and then you have a long chain of amino acids (primary structure of a protein)
Then there is a lot of folding, di-sulfide bridges and other interaction that then make the amino acids into a protein like haemoglobin (red blood cell)
