Answer:
The correct answer is - the placenta, the site of exchange of materials between the mother and the fetus.
Explanation:
In the given diagram there is a representation of a human embryo developing in the uterus. Different parts are numbered and the number three represents the site of exchange of materials between the mother and the fetus and this organ is called the placenta. It is the organ that develops between fetus and uterus during pregnancy that allows substances such as nutrients, to diffuse from the mother's blood to the fetus and connected by the umbilical cord.
Yes, this is True, if you didn't you or anything wouldn't be living, the genetic code is basically what makes you, from the physical features to anything else basically.
The molecular weight of glucose is approximately 180 daltons so each mol of glucose will be equal to 180g glucose. The concentration of glucose in the blood would be: 100mg/dl * 1 mol/180g= 5.55 mol/dl * 10^-4
Molar is expressed as mol per liter, so you need to change the volume into liters. The calculation would be: 5.55 mol/dl * 10^-4 * 10dl/liter= 5.55 * 10^-3 M= 5.55 millimoles
I believe that would be irritability.
The right option is; A. Prokaryotic cells have a nucleus
''Prokaryotic cells have a nucleus'' is the statement about prokaryotic cells that is NOT true.
Prokaryotic cells are cells that lack a true nucleus and some other cell organelles. Prokaryotic cells are found in unicellular organisms called prokaryotes. Examples of prokaryotes are; Bacteria and Archaea. The components of prokaryotic cells include plasma membrane, cell wall, cytoplasm, nucleoid, ribosomes, DNA (deoxyribonucleic acid). Most of the prokaryotic’s DNA (genetic material) is located in a middle area of the cell (nucleoid), and it contains a single large loop known as a circular chromosome.
