The choices can be found elsewhere and as follows:
<span>atural and synthetic
metabolites and nonmetabolites
proteins, carbohydrates, lipids, and nucleic acids
organic compounds and inorganic compounds
I think the correct answer from the choices is the third option. The c</span>lassifications of matter used In the 1800 are proteins, carbohydrates, lipids, and nucleic acids. Hope this helps.
This increase in volume leads to a decrease in intra-alveolar pressure, creating apressure<span> lower than atmospheric </span>pressure<span>.

Answer:
Label A: Nucleus
Nucleus can be described as the organelle in which the DNA is enclosed. The nucleus is found in every eukaryotic cell.
Label B: Vacuole
Vacuole can be described as an organelle which is used to store material such as waste. Hence, vacuole is known to be the storage house of a cell.
Label C: Ribosomes
Ribosomes can be described as structures which are present usually on the rough endoplasmic reticulum. The process of translation occurs in the ribosomes and they are hence known to be the protein manufacturing units if a cell.
Label D: Centrioles
A centriole is a cylindrical organelle which is usually made up of the protein tubulin.
Answer:
FALSE
Explanation:
An exchange of chromosome segments between non-sister homologous chromatids occurs is called crossing over.
Isopropyl alcohol causes the DNA to precipitate. When DNA is emerged in the solution, when it comes out it will ideally clump together, making it visible. Isopropyl alcohol is a key ingredient when isolating DNA. Ethanol also can be used to achieve this.
