Answer:

The correct answers are B and C. Walter Sutton and Theodor Boveri were the first to suggest that growth of cancerous cells was a result of abnormal chromosomes.

Explanation:

The chromosomal theory of inheritance is a scientific theory that relates chromosomes with the transmission of inheritable characters. It is also called the chromosomal theory of Sutton and Boveri in honor of the two people who independently developed it in 1902, Theodor Boveri and Walter Sutton. This theory states that the alleles, the Mendelian genetic factors, are on chromosomes.

Theodor Boveri and Walter Sutton independently developed the chromosome theory in 1902, Boveri, studying embryonic development in sea urchin and Sutton in this work on meiosis in grasshopper.

Sutton and Boveri's proposition in 1902 that chromosomes are the factors of Mendelian inheritance was controversial until its demonstration in 1915 by the work of Thomas Hunt Morgan in the Drosophila melanogaster fly.

tatuchka [14]

The answer is A. The first cell is in the anaphase I and the second cell is in the anaphase II.



Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis there are two anaphases - the anaphase I in meiosis I and the anaphase II in meisosis II.

<span>
</span>

<span>In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.</span>

Why does the color of the light matter ?
notsponge [240]

Answer:

Recognizing the colors and identifying the color names is an important part of a child's development.Early identification of colors helps to create the cognitive link between visual clues and words.

Explanation:

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted.White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.~Hope this helps!
