sdas [7]3 years ago
4 0

Answer:

The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

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.

First of all the reason the graph would be a curve is because, as the time increases the position changes, at first the ball is at a certain point then it starts rolling off a cliff so its moving foward and then the ball starts falling, (If too confusing here is a image http://www.mazzworld.net/U11Image1.gif)
