Answer:
Cell membrane is a semi-permeable membrane that surrounds the cytoplasm.
Explanation:
Archea contains only 1 cell and they are prokaryotic organisms. They have a different molecular setting, thus making them different from bacteria.
Cell membrane of Archea:
- In archeal cell membrane, isoprene chains are connected to glycerol lipid monolayer,
- The cell membrane is either lipid bi layer or lipid mono layer.
- Archeal cell wall contains pseudo peptidoglycan.
Cell Membrane of Bacteria:
- In bacteria, the fatty acid chains are linked to glycerol.
- The cell membrane is a lipid bilayer.
- Bacterial wall contains peptidoglycans.
Answer:
Option B== > Amino acid
Explanation:
KINDLY NOTE that the compound in the question is attached below as a picture.
From the diagram in the picture, the compound contains an aryl group, Amine functional group and a carboxylic functional group. An Amino acid compound is a compound that has carboxyl group and the amine group which makes the answer to the question to be option 'b' that is Amino acid.
Polystyrene has formula like this:(C8H8)n, there is no amine functional group attached and there is no carboxyl functional group either which makes polystyrene not to be the answer. This the same case with vitamin D which has which has hydroxyl functional group and not carboxylic nor does it has amine functional group. Although it has been revealed through series of researches that Amino acid are good solvent for Carbondioxide, the most correct option for this question will be on identifying the correct compounds with reference to their functional groups.
Radioimmunoassay is a test that the nurse expects the physician to order to check thyroid hormones.
The thyroid gland is an important hormone gland that regulates metabolism, growth, and development in the human body. It aids in the regulation of various physiological functions by continuously releasing a consistent amount of thyroid hormones into the bloodstream.
The thyroid gland generates hormones that control the metabolic rate of the body, as well as heart, muscle, and digestive function, brain growth, and bone maintenance.
The most frequent thyroid issues include aberrant thyroid hormone production. Hyperthyroidism is a condition caused by an excess of thyroid hormone. Hypothyroidism is caused by insufficient hormone production.

ANSWER: CASE-CONTROL STUDY
EXPLANATION:
An epidemiology expert will make use of a Case-control Study for proper determination of association or linkage between the oil spill and the disease outbreak (arthritis).
Case-control Study provides an observational experiment between two existing groups (two reservoirs) differing in outcome (affected and not affected), they are highlighted and compared on the basis of a context (disease outbreak; arthritis).
However, the known group is regarded as the control group and it provides a substantial guide to the confirm the validity of other experimental groups in relation to the general context (outbreak of arthritis).
Answer: The standard ECG has 12 leads. Six of the leads are considered “limb leads” because they are placed on the arms and/or legs of the individual. The other six leads are considered “precordial leads” because they are placed on the torso (precordium). The six limb leads are called lead I, II, III, aVL, aVR and aVF.
