Answer: Enviroment
Explanation: Environmental factors or conditions influences growth, health
Answer:
Lobe-finned fish are thought to be the close relatives to tetrapods because of the fact that the fins are very flexible and potentially useful for supporting the body on land, as in lungfish and tetrapods.
Explanation:
Answer:
The correct answer is - during active cellular growth and after cell lysis
Explanation:
Endotoxins, also known as LPS, are part of the outer leaflet of the outer membrane of the cell wall of gram-negative bacteria. These LPS especially Lipid A LPA released into the circulation when there is a disruption of the intact bacteria or after cell lysis. These are present in cell-associated bacteria such as Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, and others.
Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".
<u>Answer:</u> Option B
<u>Explanation:</u>
Global circulation is defined as the global connection of winds, through which the requisite heat transport from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.
The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.
Answer:
a) the pyrimidine ring is assembled before being bonded to the ribose phosphate, whereas the purine ring is bonded to the ribose phosphate as it is formed
Explanation:
There are two ways for the synthesis of purines and pyrimidines:
- de novo synthesis-from basic simple units
- "recycling" synthesis-reuse of metabolites
Purines are synthesized directly on ribose sugar, in segments.
Pyrimidines are attached to the ribose after the synthesis of the base.
