Explanation:
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms.
Key steps of the phosphorus cycle:
# Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water.
# Plants take up inorganic phosphate from the soil. The plants may then be consumed by animals. Once in the plant or animal, the phosphate is incorporated into organic molecules such as DNA. When the plant or animal dies, it decays, and the organic phosphate is returned to the soil.
# Within the soil, organic forms of phosphate can be made available to plants by bacteria that break down organic matter to inorganic forms of phosphorus. This process is known as mineralisation.
<span># Phosphorus in soil can end up in waterways and eventually oceans. Once there, it can be incorporated into sediments over time.</span>
Answer:
3. haploid; diploid
Explanation:
Sperm is male gamete or often called male reproductive cell. During the process of spermatogenesis, reductional division (meiosis) occurs in the spermatocytes and spermatids are formed which further mature to sperms. Thus as a result of meiosis, their chromosome number is reduced to half and thus they become haploid cells. During oogensis, eggs are also formed as a result of meiosis which reduces the chromosome number and so eggs are also haploid.
When during fertilization, these two haploid nucleus of these cells fuse together, they form a diploid zygote.

Out of the following given choices;
a. fructose
b. glycogen
c. sucrose
d. starch
The answer is; B.
Glycogen is only found in animals, bacteria and some fungi. It is analogous to starch (amylopectin) in plants and is also made up of glucose and sucrose polymers. It is highly branched and compact in structure than starch. Glycogen is used as a storage reserve for excess glucose in animals and is stored mainly in the liver and muscles.
