Answer:
Diamonds cam form in the mantle because of the impact of the weight of the overlying rock which bears down on it, in combination with the high temperature of the area where they are formed (about 100 miles beneath the surface). Therefore, the correct answer is option D. The weight of the rocks above the mantle results in high pressure.
Explanation:
because of the impact of the weight of the overlying rock which bears down on it, in combination with the high temperature of the area where they are formed (about 100 miles beneath the surface)
Elements cannot be broken down into other substances
Answer:
(a) crossing over: Meiosis I, Recombination
(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II
(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II
Explanation:
Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.
Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.
Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
Food is the source of energy that is used by the organism for the process of metabolism. Maggots are the larva of flies and depend on dead and decaying matters.
Maggots are:
Option C. Decomposers
This type of organism can be explained as:
- The organism is classified into different classes according to the nature of its feeding habits.
- <u>Autotrophs </u>are called the primary producer and break inorganic compounds into organic for energy.
- <u>Producers </u>are the organism that produces their food by converting solar energy into chemical energy.
- <u>Decomposers </u>are small-sized organism that lives in soil and breaks the organic compound of dead and decayed bodies.
- <u>Heterotrophs </u>are organism that depends on other sources and producers for energy.
Therefore, maggots are decomposers.
