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.
Answer:
Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms. It can also be defined as the study of energy relationships and energy transformations and transductions in living organisms.
Hypertension also known as high blood pressure is a condition in which blood pressure in the arteries is highly increased. Mexicans Americans have lower levels have lower level of awareness on hypertension and its treatment than whites and African Americans. The Mexican Americans are therefore less likely to receive treatment for hypertension and have lower rates of blood pressure control. Africans Americans have the highest hypertension prevalence in the world.
Answer: The balanced chemical equation is Pb(NO3)2 + 2KI ——-> 2KNO3 + PbI2
Explanation: A chemical equation is a condensed statement of fact about a chemical reaction which shows the kinds and number of atoms that took part in the reaction.
In writing chemical equations, the reactants are written on the left hand side of the equation with their correct formulae while the products are written on the right hand side of the equation with their correct formulae with an arrow in the middle showing the direction of the reaction.
In balancing a chemical reaction, the total mass of the reactants (number of atoms of reactants) must be equal to the total mass of the products (number of atoms of the products) formed because according to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction.
Pb(NO3)2 + 2KI ——-> 2KNO3 + PbI2
In the above equation, the number of atoms on both sides of the equation are equal.
Pb is 1 on both sides.
N is 2 on both sides.
O is 6 on both sides.
K is 2 on both sides while
I is 2 on both sides.
