Tasya [4]

Answer: Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species. A limiting factor can be any biotic or abiotic factor: nutrient, space, and water availability are examples. The size of a population is tied to its limiting factor.  The environment, what food is there and what predators live there.

damaskus [11]
In present day assortments, rescued or gathered flying creatures might be safeguarded in various manners. The most customary readiness is an examination skin, in which practically the entirety of the body inside the skin is evacuated and supplanted with cotton so the conclusive outcome looks like a fledgling lying on its back with its wings collapsed.

Meiosis does PMAT twice! That means there is a prophase I and a prophase II. There is a metaphase I and a metaphase II. Etc… If
AURORKA [14]

Answer:

If there is homologous chromosomes (metaphase I) or duplicated chromosomes/sister chromatids (metaphase II) in the middle of the cell.

Explanation:

Meiosis involves two series of nuclear divisions grouped into meiosis I and meiosis II. Each division has the same number of stages i.e prophase, metaphase, anaphase, telophase etc. Meiosis I involves the separation of homologous chromosomes i.e similar but non-identical chromosomes from each parent.

On the other hand, meiosis II involves the separation of sister chromatids (duplicated chromosome). Since METAPHASE is generally characterized by the alignment of chromosome at the middle of the cell for separation in the anaphase stage, it means that the difference between metaphase in meiosis I and II will be whether it is homologous chromosomes that are in the middle or sister chromatids.

Therefore, according to this question, I would know if the cartoon is in metaphase I or II if:

- there are homologous chromosomes in the middle of the cell (metaphase I)

- there are sister chromatids in the middle of the cell (metaphase II).
