Explanation: In humans, meiosis is the process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis.
Answer:
The correct answer is - sporophyte and gametophyte.
Explanation:
In seed producing plants such as gymnosperm and angiosperms the sporphytic part of life cycle is more dominant than the gametophytic part of life cycle. Sporophyte life cycle arise just after the formation of the zygote formation from fertilization of the gametes. The seeds are sporophytic structure that are dispersed to grow and be a full sporophytic plant with root, stem and leaves.
In mosses and ferns the case is different as there are no seed forming present the spores that are gametophytic as has n number of chromosome disperse to produce gametophytic plants that are comparatively small to sporophytic ones.
Thus, the correct answer is - sporophyte and gametophyte.
Sequence of nucleotides that compose units of DNA.
Energy used is ATP
Molecules that need ATP are those which are large and use active transport. Usually they are Ions
