Answer:
This is for the table at the top
<em>Plentiful roaming space</em>- increase - <u>because they</u><u> have more space they can live in.</u>
<em>Severe</em><em> </em><em>drought</em><em> </em><em>-</em><em> </em>decrease<em>-</em><em> </em><em> </em><u>because they</u><u> </u><u>wont</u><u> </u><u>have</u><u> </u><u>enough</u><u> </u><u>water</u><u> </u>
<em>abundant food </em><em>source</em><em> </em><em>-</em><em> </em>increase - <u>Because they have enough food to sustain themselves </u>
<em>Habitat </em><em>destruction</em><em> </em><em>-</em><em> </em>decrease - <u>Because they won't have a place to live in </u>
<em>Elimination of predators</em><em> </em><em>-</em><em> </em>increase - <u>Because there will be less animals hunting them for food.</u>
<em>Lack of competition</em><em> </em><em>-</em><em> </em>increase - <u>Because they won't have to compete for food which will allow them to have more.</u>
<em>Disease</em><em> </em><em>outbreak</em> - decrease - <u>Because the disease will kill a lot of them and can potentially cause birth rates to go down</u>
The correct answer is D. Both absorb carbon dioxide from the atmosphere.
The process of photosynthesis is carried out using atmospheric carbon dioxide by green plants. Many gases including carbon dioxide are dissolved in seawater. Some of the carbon dioxide gas remains in dissolved state but most of the carbon dioxide is reacts with water to form carbonic acid. Dissolved gases in seawater make balance with atmosphere by mixing of the surface by wind and waves. Therefore, both photosynthesis and sea water take carbon dioxide from the atmosphere.
an organism is resistant to a chemical if it has a gene that protects it from the chemical.
Answer:
Receptors are highly specific and only have high affinity for those ligands for whom they are specific.
Explanation:
Receptors are proteins that receive a stimulus or bind a ligand and mediate effects via receptor effector system.
Receptors are macromolecules that are highly specific.
The affinity between the ligand and the receptors is determind by the disassociation constant Kd.
The receptors produce maximun effect when an appropriate specific stimulus is present.
Different recptors types are present for different ligands.
For example, muscrinic receptors are specific for acetycholine and adrenergic receptors are specific for adrenaline/nor adrenaline.
It is important to know the specificity so that the body remains in a state of balance.
If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will them be able to reproduce therefore passing down the gene with larger incisor teeth
