In this case, a total of 50 WBC must be counted, so the findings are:

  • Neutrophils → 32 (64%)
  • Lymphocytes → 13 (26%)
  • Monocytes → 3 (6%)
  • Acidophils → 2 (4%)
  • Basophil → 0 (0%)

This question is about differential leukocyte practicum, we have to look for the type and number of leukocytes found on the prepared slide. (<em>For complete questions, see the picture</em>)

White blood cells have a nucleus so they are blue, there are 5 white blood cells namely:

  • Lymphocytes have a large nucleus that almost fills the cell with a thin rim of cytoplasm around it.
  • Basophils have a bilobed nucleus and are finely granular and therefore have a pale stain in the cytoplasm.
  • Neutrophils have a segmented nucleus with granules in the cytoplasm and are the size compared to others.
  • Monocytes have a kidney-shaped nucleus with an invaginated vacuole and thin cytoplasm at the periphery and are relatively in size
  • Eosinophils have a bilobed nucleus with large eosinophilic granules

After knowing the characteristics of the types of white blood cells, we can identify white blood cells in a given area.

Why is it important to know the average mutation rate when using DNA comparisons to determine
Svet_ta [14]

Answer:

mutation rates can be used to design molecular clocks in order to estimate divergence times among species  

Explanation:

In evolutionary biology, the substitution rates (also known as mutation rates) are used for the development of 'molecular clocks' which allow estimating the divergence times among species or among taxonomic groups. Molecular clocks can be designed by estimating the divergence rate of nucleotide sequences (either DNA or RNA) and amino acid (protein) sequences. These substitution rates can also be used to track how quickly viruses evolve (for example, in a pandemic situation).

2. What is an example of something studied on the molecular level (as opposed to the atomic level)?
Dmitriy789 [7]

Answer:

Something studied on the molecular level is the water.

Explanation:

Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.

The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.

With respect to other options:

  • <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
  • <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>

Based on what you have learned from your rankings in parts a and b, why is it generally hotter in summer than in winter?.
lesya692 [45]

We feel hotter in summer than in winter because the temperature is generally higher than in winter.

<h3>What are seasons?</h3>

There are three seasons on earth namely winter, summer, and rainy season. In the winter season, the temperature is cold and during summer the temperature is higher.

Timing and characteristic of season depend upon the location of the earth. The time of a year region experience season depends on it is northern hemisphere or southern hemisphere.

The southern hemispheres experiences winter while northern hemisphere experiences summer. The cycle of seasons is caused by earth's tilted towards the earth. The planet rotates around an axis.

Therefore, We feel hotter in summer than in winter because the temperature is generally higher than in winter.
