Answer: Homeostasis
Our body temperature stays constant no matter the changes that may occur in the outer environment - for example, a hot summer afternoon or a cold winter morning. This is an example of homeostasis
Explanation:
Homeostasis is the maintenance of a stable internal environment. Hence, the body maintains a stable temperature, ph level, water-salt balance etc, necessary for healthy development based on the effects of the hormonal and nervous systems.
Answer:
C. Nucleotides
Explanation:
Nucleic acids are macromolecules which are polymers of nucleotides. There are two types of nucleic acids namely: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleotides are the building blocks of nucleic acids.
A nucleotide is made up of three components:
- A phosphate group
- A five carbon sugar called pentose sugar. In RNA the sugar is ribose sugar and in DNA the sugar is deoxyribose sugar.
- Nitrogenous bases: There are four different types of bases in DNA: adenine, guanine, cytosine and thymine. In RNA thymine is replaced by uracil. Adenine and guanine are purines whereas cytosine, thymine and uracil are pyrimidines.
Nitrogenous base and sugar together are called nucleoside and when phosphate is also attached then it is called nucleotide.
Another difference would be that DNA contains the 5 carbon sugar deoxyribose while RNA usually contains the 5 carbon sugar of ribose. One differs from the other, as ribose has an additional hydroxyl group bonded to one of the carbon atoms, where as deoxyribose does not.
I think you should put a check mark by 2, 3,
5, and maybe 6.
Hope this helps.
The answer would be, True, A chloroplast is an organelle inside of cells.
