Explanation: A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
Answer:
A. To cause intact DNA to precipitate, so the activity of DNase can be determined.
Explanation:
The presence of DNase is special feature for some species of bacteria and can be used for identifying them. During DNase test, diluted hydrochloric acid (HCl) can be poured onto the agar plates so that there will be a clear zone close to the bacteria colonies. Each nucleotides are soluble in diluted HCl. But DNA is not soluble in the diluted HCl, thereby making the DNA to precipitate in the rest of the plate.
Answer:
This disorder/disease is transmitted by the mother
Explanation:
In humans, mitochondria are inherited from the mother. This genetic phenomenon can be used to trace mitochondrial genetic disorders, as well as to make evolutionary/genealogical studies (for example, in phylogenetics and phylogeographic analysis). In mammal reproduction, male mitochondria from sperm are transferred into the egg cell to be subsequently destroyed by internal processes after fertilization.
Answer:The corn plants draw water and nutrients from the soil and release water vapor into the air through their leaves. The air also brings rainwater to the soil.
