Answer:
c. carbon source
Explanation:
A "carbon source" refers to processes that<u><em> hastens carbon release into the atmosphere more than what they absorb.</em></u> Example of this is the burning of nonrenewable resources like fossil fuels.
The combustion of fossil fuels<em> increases the release of carbon dioxide.</em> Carbon is then being trapped into the atmosphere. This contributes to <em>"global warming."</em>
This is<u> opposite to</u><em><u> "carbon sink,"</u></em><em> </em>which absorbs most of the carbon than they emit.
I would first measure the temperature of the water then measure the temperature of the water AFTER the sun go down .
Answer:
The presence of cholesterol in the plasma membranes of some animal cells <u>enables the membranes to stay fluid when cell temperature drops</u>.
Explanation:
Cholesterol is an essential lipid in the basic structure of cell membranes. The membranes must have a fluid structure so that the proteins integrated in them can move ''horizontally'' to interact with their ligands and with other proteins. With excess saturated fat the membranes become rigid, but only with the necessary unsaturated fat the membranes are extremely fluid, and very sensitive to changes in temperature. Cholesterol stabilizes the structure of the membranes; preventing the collapse and crystallization between lipid chains that would lead to loss of fluidity and excessive rigidity in the membrane. By decreasing the temperature; as temperatures drop, fluidity decreases, an effect that partially counteracts the presence of cholesterol.
Answer:
is the process of breeding only organisms with desirable traits
Explanation:
Step-by- step-Explanation:
- Archaebacteria are very similar to Bacteria with respect to their cell size,prokaryotic organisation,circular DNA etc.
- Archaebacteria very similar to Gram-positive bacteria on the basis of cell structure.
- Both bacteria and Archaebacteria have several similar Metabolic Pathways.
- Unlike Bacteria Archaebacteria are habitants of extreme climates like hot springs and ice capped continents.
Thus Archaebacteria are much alike to Eubacteria.
