Kisachek [45]

Answer: Placebo effect

John is experiencing placebo effect where the pill that contains no pain killing medication has given pain relief to John. A placebo is a substance with no therapeutic effect but sometimes improves patient’s condition. This is due to patient’s expectation that the pill they take can help or ease the pain they have even if no active ingredient is present.

Therefore, the effect is more than positive thinking or believing that a treatment will work by creating a stronger connection between the brain and body as they work together.

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.
