If a germ-line cell from a frog contains 10 picograms of DNA during G1 of interphase, then how many picograms of DNA would be pr
DIA [1.3K]

Answer:

10

Explanation:

The cell cycle is composed of three states: interphase, cell division and resting.

The interphase is composed of 3 phases: G1, S and G2 (in this order). During this state the cell prepares itself  for cell division. As part of the preparation the cell duplicates all its genetic material, that is, all its chromosomes. This duplication is done during the phase S.

During the meiotic cell division (composed of meiosis 1 and meiosis 2) a single diploid mother  cell (with duplicated chromosomes) produces four haploid daughter cells. the meiosis 1 produces two haploid cells with duplicated chromosomes, and the meiosis 2 produces 4 haploid cells with normal chromosomes (no duplicated).

If a germ-line cell from a frog contains 10 picograms of DNA during G1, then this cell will have 20 picograms of DNA before the product of the first meiotic division, and will have 10 picograms at the begining of the meiosis 2 (i.e prophase II)

What happens to the water in a poolon a hot,sunny day ?​
Keith_Richards [23]

Answer:

I'm assuming you meant pool instead of poolon, i'll take it as a grammatical error. Anyhow, the water in a pool on sunny days tend to have less chlorination then on regular days. This is because chlorine forms hypochlorite ions in the water, and these are broken down by the ultraviolet light from the sun. Rainy or shiny, the weather is always affecting the chemistry in your pool.

Now, if you want to get more complicated into it, you can add a stabilizer into the pool. The common one safely used in pools is cyanuric acid. This almost completley prevents all de-chloronification.

I hope this information was of any use to you.

Answer:

Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.

Explanation:

Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.
