Oxazolidinones, Ansamycins, and Tetracyclines
These class of antibiotics are mean't to disrupt bacteria that are gram positive.
Answer:
A. Based on our results, students who do 1 hour of chores per night
have grades that are on average 0.2 points higher than students
who do no chores.
Explanation:
In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.
From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.
The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.
Transpiration<span> is the process which moisture is carried through plants from roots to small pores on the under part of leaves, where it changes to water vapor and is released to the earth. </span>Transpiration<span> is essentially evaporation of </span>water<span> from plant leaves.</span>
Explanation:
Surface area and pores play important roles in the cell.
Pores are the tiny holes on the surfaces of a body. They help to facilitate movement of materials in and out of the cell.
The surface area is the amount of space the surface of a cell occupies.
- Pores in a cell needs to be in proper shape in order to facilitate movement of materials.
- When the pores in a cell are too large, too much materials are bound to leave the cell. Tiny pores makes it difficult for the cells to have enough materials to function properly well.
- The surface area of a cell allows for the diffusion of materials in and out of cell.
- The larger the surface area of a cell, the more and better reactions takes place because they will receive important life sustaining resources.

Nucleic acids, proteins, carbohydrates, and lipids are the four major types of biomolecules that form all living things. These biomolecules consists of monomers linked together by covalent bonds to form polymers.
- Nucleic acids, proteins, carbohydrates and lipids can be classified according to their basic elements, monomer constituents, and functions.
Basic elements:
- Nucleic acids: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Phosphorous (P)
- Proteins: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Sulfur (Z)
- Carbohydrates: Hydrogen (H); Carbon (C); Oxygen (O)
- Lipids: Hydrogen (H); Carbon (C); Oxygen (O); Phosphorous (P)
Monomer constituents:
- Nucleic acids: nucleotides
- Proteins: amino acids
- Carbohydrates: monosaccharides
- Lipids: fatty acids and glycerol
Functions:
- Nucleic acids: contains the hereditary information to synthesize proteins
- Proteins: regulate metabolic processes (enzymes), the main biomolecule of cellular structures
- Carbohydrates: store energy (short term); form cellular structures
- Lipids: store energy (long term); the main component of biological membranes
Examples:
- Nucleic acids: DNA and RNA
- Proteins: lactase; collagen
- Carbohydrates: starch (polysaccharide); glucose (monosacharide)
- Lipids: phospholipids; cholesterol
