The correct answer of this question is option B. Natural selection acted on the variation that was present in the population. This adaptation was a result from the Industrial Revolution. The dark-colored moths have camouflaged more effectively than the light-colored ones.
Answer:
I believe that climate change is one of the most serious problems of young generations. At the current pace of greenhouse gas production global warming will increase exponentially, which will result in rising sea levels, certain animal species going extinct. Deforestation also severely adds to this problem as wood is a finite resource on Earth and the more trees we destroy the less oxygen there is relative to the amount of carbon dioxide in the atmosphere. This will continue to weaken the ozone layer which could result in catastrophe from sun flares or radiation. I do believe that in the near future drastic measures will be taken to prevent these events.
Explanation:
The most common type of bacteria that causes community-acquired pneumonia (CAP) is Streptococcus pneumoniae. Other bacteria that cause CAP include Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila. Mycoplasma pneumoniae is known to be the main cause of walking pneumonia.
The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".
<u>Option: B</u>
<u>Explanation:</u>
In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.
Chromosomal mutations are often caused by chemical agents or by mutagens.
The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.
