<span>False. E.coli is generally about 2 micrometers in size compared to white blood cells which are around 13 micrometers in size. Also, white blood cells have a characteristic segmented nucleus with two to five lobes joined by fine strands of chromatin.</span>
Ans.
Cell differentiation is defined as a process, by which less specialized cells, such as embryonic cells become more specialized. The process of cell differentiation is regulated by gene expression. Gene expression involves a specific group of genes that are turned on (expressed) or turn off (repressed) and dictates a cell's function.
A fertilized egg represents a single, non-specialized cell that develops into a complex, multicellular organism by cell differentiation. Thus, a adult rabbit looks so much different as compared to a single fertilized cell or zygote, due to cell differentiation, which is regulated by gene expression.
Below are the options:
Having two phases of meiosis allow for more unique cells to be produced.
Meiosis is a form of asexual reproduction which leads to more genetic variation.
Meiosis produces 4 haploid daughter cells which all contain identical DNA segments.
<span>Crossing over during metaphase allows segments of DNA from 2 parents to SWAP and produce non-identical haploid cells.
</span>
The answer <span>Meiosis is a form of asexual reproduction which leads to more genetic variation</span>
Answer: B!
Explanation: This simply makes the most sense, as the population will go down when individuals die, and grow when more are born
A simple question, but I hope this helps you :)
