disa [49]

The amount of glucose in each ml of their blood will be 0.00138 g.

<h3>Blood glucose concentration</h3>

The concentration of glucose in the person's blood is 1.38%.

This means that there is 1.38 g of sugar per Liter of blood.

1 Liter of blood contains 1.38 g of glucose, and there is 1000 mL in 1 Liter of blood.

1000 mL contains 1.38 g

1 ml contains = 1.38 x 1 / 1000 = 0.00138 g

This means 0.00138 g of glucose will be present in every 1 mL of the person's blood.

Identify early ideas about evolution?
Setler79 [48]

Explanation:

Naturalists began to focus on the variability of species; the emergence of paleontology with the concept of extinction further undermined static views of nature. In the early 19th century Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution.

In classical Latin, though, evolution had first denoted the unrolling of a scroll, and by the early 17th century, the English word evolution was often applied to 'the process of unrolling, opening out, or revealing'. It is this aspect of its application which may have been behind Darwin's reluctance to use the term.

Answer:

22 pairs of autosomes, 1 pair of sex chromosomes, I notice that the X and Y chromosomes are sex chromosomes and that they are different in length and size., The sex of this organism is male, as the genotype XY can only mean a male gender; female gender is denoted by the genotype XX., You didn't put in Karyotype A., The special circumstance is with group 21 of chromosomes. There are 3 instead of 2 in that group., This circumstance results in a condition known as trisomy 21, or Down Syndrome. Down syndrome causes a distinct facial appearance, intellectual disability, developmental delays, and may be associated with thyroid or heart disease. , Name the karyotype "Down Syndrome Karyotype?" (I'm not sure on the last one)
