Nataliya [291]
The organism that Michelle is studying can best be classified into the domain EUKARYA.
The three domain classification system was introduce by a scientist named Carl Woese. The classification system categorizes all living organisms into three basic domains, which are: archaea, bacteria and eukarya. The archaea and the bacteria groups represent the prokaryotes while the eurkarya group represent the eukaryotes. Eukaryotic organisms are divided into plants and animals. The eukaryotic plants, even though they are multi cellular like animals have some features, which distinguish them from the animals, these include: ability to produce their own food and inability to move around their environment.

Levart [38]

Answer:

Catabolite repression

Explanation:

Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.

It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:

  • sensory systems-detects ratios of glycolytic intermediates,
  • global regulators-control the expression of genes that encode for enzymes.

Chromosome 11 in humans is made up of over approximately 135 million base pairs. It represents about 4-5% of the total DNA in cells.

<h3>What do you mean by Chromosomes?</h3>

Chromosomes may be defined as a thin-thread-like structure that is present in the nucleus of the cells that contains genetic information.

Chromosome 11 contains about 1300-1400 genes that furnish instructions for the cells to make proteins for metabolic activities.

The genetic disorders that are associated with the chromosome 11 are:

  • Albinism
  • Thalassemia
  • Autism
  • Jacobsen syndrome
  • Beta-Ketothiolase deficiency and many more.

Each of the above genetic disorders has its own specific modes of causing symptoms and infections in the human body.

Therefore, it is well described above.

Heterozygote advantage should be most closely linked to which of the following?
BigorU [14]

The correct answer is: B) stabilizing selection

Stabilizing selection is a type of natural selection in which the population mean (non-extreme trait value) is favored over extreme values. It favors the intermediate variants such as heterozygous phenotype (more than both homozygous). This is the most common type of selection, because most traits change little over time (not by favoring extreme traits).
