Answer:
<em>D) lining up of chromosomes in the cell</em>
Explanation:
Prophase can be described as the first stage of cell division. During this phase, The chromatin material condenses and becomes compact so that the chromosomes become visible. The nuclear envelope disintegrates and the nucleolus disappears. Hence, the choices mentioned in option A, B and C occur by the end of prophase.
Metaphase is the third phase of cell division. During this phase, the chromosomes line themselves in the centre of the cell. Hence, the lining of the chromosome does not occur by the end of prophase. This occurs during the third stage.
I would say sexual selection
If you have options though I would feel more confident giving you my answer, if not, that's fine too.
Hope this helps :)
Answer:
a.) Biomass is the total mass of biological material, both living and recently dead, in a defined area.
b.) The Sun's light is the original source of these energy forms. Both are formed into original material by photosynthesis, sunlight combining carbon dioxide and water into plant matter.
c.) Coal, oil and natural gas (or methane).
d.) Non-renewable resources cannot be naturally replaced in a small enough timescale for us to have an unlimited supply. When we have run out, it will take natural processes millions of years to form them again.
This statement is false.
When two small parts of a species population are separated geographically the phenomenon of founder effects occurs. Both of these two newly formed populations have the same probability of acquiring neutral mutations. Due to the geographical separation, the number of alleles for some genes in the parent population is larger than the two new populations.
Answer:
, mitochondria appear to originate only from other mitochondria. They contain their own DNA, which is circular as is true with bacteria, along with their own transcriptional and translational machinery.
