Answer: Option A) Double-stranded DNA

Explanation:

First, the presence of thymine infers that the genome is DNA.

Then, to determine whether it is single or double stranded, we check if the sum of all nitrogenous bases is equal to 100%

A + C + G + T = 100%

28% + 35% + 20% + 17% = 100%

Since all bases makes 100%, we can conclude that the genome is a double stranded DNA

In order for plants to make their own food, they must go through a process called photosynthesis. This process occurs in the chloroplasts of a cell. To begin this process, all items needed must go to the cells of a plant. Water and nutrient are absorbed from the soil through the roots. A tube called the xylem carries only water up the stem to the rest of the plant. Gas exchange in the plants occur in the tiny pores of a leaf called the stomata. This is opened and closed by the guard cells. The food produced by this process is called ATP and it is a macromolecule known as a nucleic acid.

Match each leukocyte to its normal percentage in a differential cell count. A. 50-70% B. 20-40% C. 2-8% D. 1-4% E. < 1% basop
Vsevolod [243]

Answers:

A. 50-70% - neutrophils

B. 20-40% - Lymphocytes

C. 2-8% - monocytes

D. 1-4% - eosinophils

E. < 1% -  basophils

Explanation:

The blood differential test is used to estimate the percentage of each class of white blood cell (WBC) present in the blood and to indicate the presence of abnormal or immature cells.

The Test is Performed by taking of blood sample which is smeared onto a glass slide, then it's stained with a unique dye to indicate the class of white blood cells.

The Five class of white blood cells are

Neutrophils

Lymphocytes (B cells and T cells)

Monocytes

Eosinophils

Basophils

The different class of white blood cells are given as a percentage:

Neutrophils: 40% to 60%

Lymphocytes: 20% to 40%

Monocytes: 2% to 8%

Eosinophils: 1% to 4%

Basophils: 0.5% to 1%

Band (young neutrophil): 0% to 3%
