Answer:
A. DNA replication
B. Two haploid daughter cells
C. Four haploid daughter cells
D. No, they are not the same
E. Gametes
Explanation:
A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.
B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.
C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.
D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.
E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.
Answer:
Answer is A
Explanation:
Urea consists of carbon, nitrogen and oxygen. You can find it in urine, sweat, blood and milk in mammals. In its most concentrated form, it is urine. Urea is a crystalline compound, and the nitrogen content is always at least 46 percent when dry.

Answer:
The liquid would be equivalent to Cytoplasm
The particles would be equivalent to orgnaelles
Explanation:
Cytoplasm is the liquid-like substance in the form of a gel that is also referred to as the protoplasm which is found outside the cell of living things. It is majorly mad up if dissolved molecules and water, as well as several cell organelles that carry out specific functions.
Comparing salad dressing to a cell, the liquid in the salad could be likened to the cytoplasm of a cell, while the particles in the salad could be likened to the organelles in a cell which performs various functions.
The answer is (3) an increase in the proportion of offspring <span>that have favorable characteristics.
</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Peppered moth color variation is a good example of natural selection.<span>During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.
Therefore, the </span>proportion of offspring <span>that have favorable characteristics in such environment will increase.</span>
