Answer:
The big cause in the extinction of many terrestrial vertebrates species is the hunting while the second cause is the habitat change. ... Hence if the habitat change, they are unable to survive and their population size will decrease.
Explanation:
The gel like substance inside the cell but outside of the nucleus is known as <em>Cytoplasm </em>
I assume the second option because the half sun half shade situation would provide the nutrients for the plants and at the same time nit half too much( since some plants need indirect sunlight and this is a good compromise) also glass is typically used in greenhouses and therefore would be my container of choice and fertilizer will assist in plant growth
Answer:
6 chromosomes each
Explanation:
Meiosis is the cell division that results in daughter cells with a reduced number of chromosomes (by half). Meiosis is used only by sexually-reproducing organisms to produce gametes. Since meiosis reduces the chromosomal number, it occurs in a two-step division process viz: Meiosis I and Meiosis II.
Meiosis I involves separation of homologous chromosomes (similar but non-identical chromosomes received from each parent). In the Anaphase stage of meiosis 1, each homologous pair of chromosomes that makes the organism diploid (2n) is separated. Hence, the resulting cells of meiosis I will have a reduced chromosome number (haploid,n).
In this case of a diploid frog with 12 number of chromosomes. If a germline cell or reproductive cell divide by meiosis, in meiosis I, each pair of the 6 pairs of homologous chromosomes of the frog will separate into opposite cells. Hence, at the end of meiosis I, each daughter cell will have 6 chromosomes in a haploid state.
In meiosis II, sister chromatids (replicated chromosomes) separate instead. Each separated chromatid becomes a full chromosome in each gamete.
