Almost all of the cells in your body share the same DNA as was found in that first cell. Your DNA contains all of the information needed for making you. This information is stored in the over 20,000 human genes found in almost all your cells.

Answer:

B. No

Explanation:

First, let's watch what it looks like when a population is not evolving. If a population is in a state called Hardy-Weinberg equilibrium, the frequencies of alleles, or gene versions, and genotypes, or sets of alleles, in that population will stay the same over generations (and will also satisfy the Hardy-Weinberg equation). Formally, evolution is a change in allele frequencies in a population over a very long period of time, so a population in Hardy-Weinberg equilibrium is not evolving.

E. coli belongs to the genus Escherichia

Taxonomically, <em>Escherichia coli </em>is categorized as belonging to the phylum Proteobacteria, class Gammaproteobacteria, family Enterobacteriaceae, order Enterobacteriales, and genus Escherichia (named after its discoverer, Theodor Escherich).

Escherichia coli (E. coli) are typically found in warm-blooded organisms' lower intestines. The majority of E. coli strains are not harmful, but some can seriously poison food.

A Shiga toxin-producing E. coli (STEC) is capable of causing severe foodborne illness.

Raw or undercooked ground meat products, raw milk, and fecal contamination of vegetables are the most common causes of STEC outbreaks.

The illness is usually self-limiting, but it can progress to a potentially fatal condition like haemolytic uraemic syndrome (HUS), especially in young children and the elderly.

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%
