The correct answer is option C, that is, one may become dehydrated because the kidneys will not hold onto enough water.
Hypothalamus monitors the functions like hunger, thirst, respiratory and cardiac function, and regulation of internal temperature. It also plays an essential function in the modifications of mood and emotions.
Thus, if hypothalamus is not functioning properly, then the mentioned functions of the gland may get hampered like the kidneys would not be able to hold enough water and may lead to dehydration.
It is B organs- organ systems- organism
Answer:
Reproductive isolation, as well as taxonomic and genetic differences, can be used to discover and classify new species
Explanation:
According to the biological concept of species, "the species can be recognized to be reproductively isolated by morphological, behaviors and physiological processes that prevent interbreeding with other groups". These differences can include taxonomic changes and the lack of homology between conserved genes, which enable us to discern that two individuals belong to different species. In genetics, for example, the mitochondrial gene Cytochrome Oxidase I (COI) is widely used to differentiate between species because it is evolutionarily conserved, thereby important sequence differences may indicate that two individuals belong to different (even cryptic) species.
Answer:
A. pH
Explanation:
Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.
However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.
The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.
