<span>She is at an increased risk of osteoporosis. Girls who first experience menarche at later ages are more disposed to having a lowered bone density and osteoporosis later in life. This is due to having a reduced peak bone mass, which can increase the risks of fracture.</span>
Answer:
C. active transport driven directly or indirectly by metabolic energy
Explanation:
The intestinal mucosa is the tissue that lines the inner walls of the intestines. It is characterized by the pleated appearance, which facilitates the absorption of nutrients already deferred and the formation of fecal cake. Most nutrients are absorbed by this region through active transport directly or indirectly driven by metabolic energy.
The answer is <span>C. glycolysis, Krebs cycle, electron transport</span>
Cellular respiration includes glycolysis, link
reaction, Krebs cycle, and electron transport chain (ETC), in that order. The
main function of ETC is a production of ATP. In this series of
oxidation-reduction reactions, electrons from the previous stages of cellular
respiration are taken and transported to the oxygen which is the final acceptor
of electrons. As the result, water and ATP are produced.
A behavior must affect an organisms fitness and have a genetic basis.
The right answer is water.
A solution is a liquid containing several constituents
* The majority constituent is called solvent. Most often consists of water, the solution is called aqueous solution.
* The substances in solution are called solutes.
* The species in solution are either molecules or ions.
If we add water in the aqueous solution, we will have a dilution. On the contrary, if we add solute or remove water (pure water in solutes) we will have a concentration.
