Oxygen, the element, is recycled in a biogeochemical cycle within its three main reservoirs: the atmosphere, the total content o

f biological matter within the biosphere, and the Earth's crust. The driving force of the oxygen cycle is photosynthesis, which is responsible for modern Earth's atmosphere and life on Earth. Using the data collected, hypothesize as to which reservoir contributes least to the recycling of oxygen from year to year.

A sperm and egg are each _________. They fuse during fertilization to produce a _________ cell. A sperm and egg are each _______
blsea [12.9K]

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.
