zavuch27 [327]

Answer:

There is no diagram provided so I will just explain the mitotic cell cycle.

Here’s a quick basic arrangement in chronological order interphase, mitosis, and finally cytokinesis.

So first you start with interphase which consist of three phases G1 phase, S phase, G2 phase. Cellular growth occurs in G1 phase of interphase this is followed by S phase which is simply when DNA replication occurs. Final this is followed by G2 phase or further growth in preparation for mitosis and/or meiosis.  

I am only going to explain mitosis but just so I don’t confuse you meiosis can also follow interphase. So mitosis consist of four phases. Prophase, metaphase, anaphase, and telophase.

Prophase: in this phase the nuclear membrane would dissipate and the chromosomes would condense.

Metaphase: then in metaphase the chromosomes would align in the center of the cell and spindle fibers or microtubules would began growth from the centrioles.  

Anaphase: by the start of this phase spindle fibers would have attached themselves to the chromosomes kinetochores. In this phase the chromatids would separate and that’s really it as you can tell this is the shortest phase in mitosis.

Telophase: finally the chromosomes would be brought to the polar opposite ends of the cell and the nuclear membrane would reform. Also the chromosomes condensed chromosomes would unravel eventually they would be invisible.

Finally the cell would enter cytokinesis were it would split at the cleavage furrow which would have started in anaphase of telophase, all a cleavage furrow is, is microfilaments “pinching the cell” which is just them pulling on either side of the center of the cell.

damaskus [11]

Answer:

c) 55 degrees

Explanation:

This inclination is also done so there is less inclination and extension of the neck since the patient ends up with the OML (orbitomeatal line) more perpendicular to the IR plane.

A twisted zipper is used as a model of eukaryotic DNA. How could the model be developed to represent DNA replication in eukaryot
san4es73 [151]

Answer:

The model of the DNA can be related to a zipper. Just like the zipper, the two strands of the DNA are joined together by the hydrogen bonds present between the nucleotides. At the time of replication, the coiling of the two strands is undone just as the zipper is open. The two strands of the DNA open and separate just as the two stands of the zipper open and separate. Each strand can give rise to anew strand.

Just as the opening and closing of the zipper can cause damages in the zipper, just like this replication can cause errors in the DNA which lead to mutations.

Which of the following structures would be considered an accessory organ to the digestive system and NOT part of the alimentary
kati45 [8]

Answer:

The correct answer to the question: Which of the folowing structures would be considered an accessory organ to the digestive system and NOT part of the alimentary canal?, would be: A: Pancreas.

Explanation:

The accesory organs to the digestive systems are defined as organs that in some part play a role in the entire process of digestion of food, but are not directly a part of the digestive tract itself. As such, the pancreas, though resposible for secreting components that are essential to the process of absorption of nutrients, and management of them, is not part of the digestive system and fufills tasks outside of the purpose of the digestive system, which is, to manage the digestion, absorption and excretion of nutrients and foodstuffs.
