Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves.
As baby scorpions grow larger, which process occurs in their body (somatic) cells?
A.Mitosis separates one cell into four cells.
B.Mitosis makes copies of the cell nuclei.
C.Meiosis produces all of the new body cells.
D.Meiosis splits the chromosome numbers by four.
Baby scorpions are born with fully developed bodies, each with many special parts such as stinging tails. Which process enables baby scorpions to develop various kinds of body parts from a single zygote?
A.cell breakdown
B.meiosis
C.reproduction
D.cell differentiation

The answer to the first question is B. Mitosis divides replicates cell nuclei, but does not necessarily make two daughter cells. Cytokinesis is the process by which two cells split into daughter cells.
Additionally the first question is fundamentally sound scientifically.
The answer to the second question is D. Cells differentiate to produce different cell types (variations), which allows for the large amount of cell diversity that many organisms display, including the scorpion.

You should read your material in order to answer these questions. I can tell you that question 1 is bogus. I know what they are getting at, and which answer they want you to choose, but the answer itself is not scientifically correct. The two processes of mitosis and meiosis happen in two different cell types, either somatic cells or germ cells. They are inquiring about somatic cells.
Question 2 is more clear-cut and the answer should be fairly obvious.

1: B, I think. Meiosis only takes place in cells that will be used for sexual reproduction, not body cells, and mitosis only splits a cell into 2, not 4.
2: D. Differentiation is the process by which different tissue types are formed from a single-celled zygote.

No, you're no longer extraordinary. as quickly as you strart donning it, you will consistently could desire to. My epidermis substitute into large till i began out donning makeup, now that's all mild and splotchy. desire i wouldn't in any respect began. i think of organic faces are lots prettier. in case you prefer to objective something mild without looking madeup, I even have a pal who in simple terms wears a tad of eye shadow, like a mild crimson shade, per probability some brown/black mascara (low-value kind) and lip gloss. She is alluring!
