Which statement would be used in an argument against the use of human embryonic stem cells for therapy?
Marizza181 [45]

The statement 'obtaining embryonic stem cells for use in therapy requires the destruction of embryos' would be used in an argument against the use of human embryonic stem cells for therapy. It is a type of stem cell therapy.

<h3>What are embryonic stem cells?</h3>

The embryonic stem cells are cells obtained from embryos that have the property to divide and specialize into different tissues.

The embryonic stem cells can be differentiated in the laboratory for the development of specific cell lineages.

The therapy using embryonic stem cells involves the use of these types of cells and the destruction of an embryo.

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. &lt; 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%

In a certain triangle ABC , A equals 30°, B equals 50°, and the side AB equals 3 in. Use a protractor and a straightedge to cons
natali 33 [55]
If you were to compute this, Angle C should be equal to 100°.

In a triangle, all angles sum up to 180°.

In triangle ABC, where the m∠A =30° and m∠50°:

m
∠A + m∠B + m∠C = 180°
30° + 50 + m∠C = 180°
80° + m∠C = 180°
m∠C = 180° - 80°
m∠C = 100°

The triangle should look like the picture attached.
