Answer:
Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
Explanation:
Answer: A)Consumer
Explanation:
The snake consumes animals like mice thus it is a consumer. If u want more explanation comment
It's for sure not A because having thick fur will only make you hotter, and thus you will suffer a heat stroke. It's not C because small ears would not be long enough to provide you with cooling. That one does not make sense. It could be D, but the species would need to have alot of muscles in order to be consistently flapping there ears for the constant hear. Answer is B because it is the most logic, and the fewer amount of fur, the less hotter you will be, especially if your fur provides insulation.
Answer is B. Species B because fur would provide insulation.
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 .
