Hi there,
Cytokinesis is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.
This is how it occurs:
Animal cells: divide by a cleavage furrow
Plant Cells: divide by a cell plate that eventually becomes the cell wall.
Hope this helped :)
Have a great day
Answer:
<u>Sister chromatids are identical forms of chromatids of a chromosomes. They are mostly formed by semi-conservative replication of DNA molecule of a single chromosome.Thus they are like </u><u>'photocopies' </u><u> of original parent chromosomes; joined together at the Centromere</u>.
They are exactly similar in all ramification; with the same gene and allele compositions..
<u>However; slight differences arise between the two identical sisters due to </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in the length of telomere repeats.</u>
Non-sister chromatids are dissimilar forms of chromatids of a chromosomes formed when each half of a chromosome at fertilisation from separate haploid sex-cells, of each parent. fused.They contain different genetic composition;because they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.
<u>However, they are genetically similar in composition; if they are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by chromosomal crossing-over between the non-sister chromatids on the chromosomes ; therefore identical genetic characteristics are shared .
Explanation:
The characteristic which was true of mendel's F1 generation plant is that they were all hybrids.
Answer: A
Explanation: None of the others Pollinate except for moths, who only do at night.
Answer:
Coniferous/boreal forest (forest consisting of evergreen and/or cone bearing trees), short summers and long cold winters; the animals there have thick fur to stay warm.
