What would happen if photosynisis stoped happing on earth
Neporo4naja [7]

We can confirm that the absence of photosynthesis on Earth would cause a mass extinction of most of the species on the planet.

<h3 /><h3>Why would the absence of photosynthesis be so harmful?</h3>

The process of photosynthesis is extremely important as it produces oxygen as a byproduct. The absence of this process on Earth would limit the available oxygen in the atmosphere which would at some point be entirely consumed. From then on, most species on the planet would die out as they require oxygen to live. Most plant species would also die off as they use photosynthesis to sustain life.

Therefore, we can confirm that the absence of photosynthesis on planet Earth could be considered an apocalyptic event as it would cause a near-complete extinction of life on the planet.

Domestic cats have 38 chromosomes in their diploid cells. If a diploid cat cell enters meiosis, how many chromosomes and double-
sdas [7]

Answer:

Meiosis is a reduction division of diploid cells.(2n) Chromosomes numbers are reduced with each successive division stages  of meiosis 1 and 2, to haploid(n).

Cats  have  38 diploid  somatic (body)chromosome (2n) in the somatic cells  and are reduced to 19  new   varied haploid cells (n) of chromosomes in the gametes.

In cats, as in other mammals, during spermatogenesis in (seminiferous tublule of testis) and oegensis(in the ovaries);<u>meiotic  reduction division</u> reduced the diploid  somatic chromosomes to haploid chromosomes  in  sex gametes.

Therefore 38 chromosomes will be in  the somatic chromosomes, while the sex gametes, with double-helical molecules of DNA, at the end of meiosis II will  have 19 chromosomes, half of the somatic chromosomes.
