In detail what are the main differences in the 3 domains

Biology
1 answer:
DedPeter [7]2 years ago
8 0

Answer:

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.

What is the purpose of the electron transport chain in the thylakoid membrane?
Feliz [49]

Answer:

To produce energy in form of ATP

Explanation:

The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors.  These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP.  Later on these electrons will reach the other photosystem, to produce reducing power.  This is in plants.

Cyclic photosystems also exist, in some bacteria, for example,  and only produce energy as ATP.  They also have an electron transport chain.

A diagnostic test that would be used to determine the amount of protein being excreted and to estimate the kidneys
stiks02 [169]
<span>The type of diagnostic test that is used to tell how much protein is being excreted by the kidneys and to estimate the filtration abilities of the kidneys is a twenty-four-hour urine collection. This test collects urine over a 24-hour period to be sent to a lab for analysis, and the components of the urine sample can be used to detect certain diseases.</span>

what is the meaning of phosphoryl transfer potential and what does it mean to have a high or low phosphoryl transfer potential?
makvit [3.9K]

Phosphoryl-transfer potential is the ability of an organic molecule to transfer its terminal phosphoryl group to water which is an acceptor molecule. It is the “standard free energy of hydrolysis”.

Explanation:

This potential plays a key role during cellular energy transformation by energy coupling during ATP hydrolysis.  

A compound with a high phosphoryl-transfer potential has the increased ability to couple the carbon oxidation with ATP synthesis and can accelerate cellular energy transformation.  

A compound with a high phosphoryl-transfer potential can readily donate its terminal phosphate group; whereas, a compound with a low has a lesser ability to donate its phosphate group.

ATP molecules have a high phosphoryl transfer potential due to its structure, resonance stabilization, high entropy, electrostatic repulsion and stabilization by hydration. Compounds like creatine phosphate, phosphoenolpyruvate also have high phosphoryl-transfer potential.

Biological control methods for managing insect pests are effective for reasons that include which of the following? They promote
Semenov [28]

Answer:

Option B, They generally focus on one target insect to ensure that the target insect population remains low.

Explanation:

Biological pest control methodologies are focused towards a specific species of pest and do not harm the non-targeted species. These methods are environment friendly and do not produce any harmful residues. Also they do not develop any kind of resistance in species due to which the same bio pesticide can be used again and again. Since these methods have high specificity, they may require usage of two or more bio pesticides all together.  

Hence, option B is correct
