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.

What evidence is there that the 15 species of finch all evolved from one common ancestor?
antoniya [11.8K]
Darwin’s Finches: Darwin observed that beak shape varies among finch species. He postulated that the beak of an ancestral species had adapted over time to equip the finches to acquire different food sources. This illustration shows the beak shapes for four species of ground finch: 1. Geospiza magnirostris (the large ground finch), 2. G. fortis (the medium ground finch), 3. G. parvula (the small tree finch), and 4. Certhidea olivacea (the green-warbler finch) the Grants measured beak sizes in the much-reduced population, they found that the average bill size was larger. This was clear evidence for natural selection of bill size caused by the availability of seeds. The Grants had studied the inheritance of bill sizes and knew that the surviving large-billed birds would tend to produce offspring with larger bills, so the selection would lead to evolution of bill size. Subsequent studies by the Grants have demonstrated selection on and evolution of bill size in this species in response to other changing conditions on the island. The evolution has occurred both to larger bills, as in this case, and to smaller bills when large seeds became rare.

Translation ends when
Y_Kistochka [10]

<span>Translation

</span>Remember that transcription happens in the nucleus as it changes from DNA to mRNA.  In translation,
    the mRNA first has to leave the nucleus and go into the cytoplasm of the cell.  The process of translation actually occurs in the cell’s ribosomes.

<span>
</span>The process of translation uses the genetic code on the mRNA strand to direct the construction (making) of a protein molecule. <span>
</span>1.  A ribosome attaches to an mRNA molecule in the cytoplasm.<span>
</span>2.  As each codon passes through the ribosome, tRNA molecules bring the matching amino acids into the ribosome.  Each tRNA has a set of 3 unpaired nitrogenous bases called an anticodon which matches up with the codon coming through the ribosome.  So one end of a tRNA has an anticodon and the other end carries the amino acid which is how the code is translated.<span>
</span>3.  The ribosome and the rRNA molecules it contains attach the amino acids together as they are being translated.  The protein chain will keep growing until the ribosome reaches the stop codon on the mRNA.  At that point, translation is done and the ribosome lets go.


Hope this helps!!!

With respect to angiosperms, which of the following is incorrectly paired with its chromosome count?
Ierofanga [76]

Answer:

Megaspore—2n.

Explanation:

Angiosperms are the fruit bearing plants and reproduce by the process of sexual reproduction. The chromosome number are specific at each stage of the cell cycle of the angiosperms.

Microspores , egg are haploid. Zygote is diploid in nature. Megaspores get germinate into the female gametophytes and these are haploid in nature. Megaspores are also haploid in angiosperms.

Thus, the correct answer is option (b).
