A client has been recently diagnosed with type 2 diabetes, and reports continued weight loss despite increased hunger and food c
klasskru [66]

Answer:

polyphagia.

Explanation:

  • Type 2 diabetes is diabetes which usually occurs in adults os characterized by frequent urination, increased thirst, and unexplained weight loss.
  • Usually, a person suffering from diabetes even though he has unexplained weight loss also experiences increased appetite and thus, consumes more food this is because even though the needed glucose is being wasted, the body's requirement for feel continues.
  • As a result, a person with diabetes feels hungry and eats more (polyphagia). Despite eating more, he or she loses weight as the body uses fat and protein to substitute for glucose.

liq [111]

The answers are Stabilizing selection, directional selection and disruptive selection respectively.

<h3><u>Explanation</u>:</h3>

In case of a population of a species, there exists both the homozygous alleles as well as the hybrid of the two characters. This leads to co existence of both hybrids and homozygotes together in a population.

Now because of the natural selection, there remains some characteristics in either homozygotes or in hybrids which gets special advantages over other. So nature selects the preferred race and the number of those individuals in the population increase.

If number of one of the homozygotes increase, then it's the directional selection.

If the number of the hybrids increase, then its Stabilizing selection.

And if both the homozygotes are selected, then it's divergent selection.

What is the function of the following organelles?
MrRa [10]

Answer:

Explanation:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.

The plasma membrane is the same as a cell membrane

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

​Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
