Answer: haploid, 23 chromosomes and 23 chromatids of
Explanation:
Meiosis takes place in two divisions meosis 1 and meosis 11.
Meiosis 1 is reduction division, because two new daughter nuclei are formed with haploid chromosomes number of the parent nucleus.
Therefore based on this question; the 46(2n) chromosomes in example the ovary will be halved to (23)n. 2n ⇒ n .
So far chromatids, are newly formed chromosomes there will be 23 chromatids, since the haploid chromosomes are 23 in number
However, so far the entire new daughter cells contains half the total chromosome number of the parents they are haploid.
False, because chromosomes are architecturally very compact and genetic code for them, they are not responsible for the specific features we witness.
Contrary to appearance, chromosomes are very compressed physically, allowing for the containment of these enormous DNA structures within the cell nucleus. A human's chromosomes. The genetic code refers to the set of guidelines that living cells employ to convert data from genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. The ribosome does translation by linking genetic code amino acids in the order dictated by messenger RNA (mRNA) and employing transfer RNA (tRNA) molecules to transport amino acids.

The right answer is A.
Insecticides are active substances or phytosanitary preparations with the property of killing insects, their larvae and / or their eggs. They are part of the family of pesticides, themselves included in the family of biocides, both of which are regulated in Europe by specific directives.
Some pestiids such as organoclorides are broad-spectrum, ie they act on several insects at the same time (whether they are good or bad).
I think it would be both (man-made or natural disaster)
By natural selection, the nature of species gradually changes to become adapted to the environments. This variation of traits in a population is what gives the organisms the ability to survive environmental changes. If not the species becomes extinct.
