Answer: b. reaction 3
Explanation: When an enzyme is present in a reaction acts as a catalyst, increasing velocity of reaction and decreasing the activation energy, when not present an enzyme the reaction velocity is very low and implies high activation energy, being unfavorable to the system
Answer:
It needs protein channels known as Aquaporins.
Explanation:
These Aquaporins, also referred to as water channels, are membrane proteins which serve as passageways for water. Aquaporins facilitate the transportation of water and other neutral molecules across cell membranes.
Salinity refers to the principal characteristic that determines whether an aquatic ecosystem is classified as marine or freshwater. It is the measure of all the salts dissolved in water.
<span>Dehydration synthesis involves substances combining together (synthesising) while at the same time losing water (dehydrating). The process of lipids turning into fatty acids involves dehydration synthesis.</span>
Climate variations are averaged by using weather conditions from past years. Climate variability varies by seasons, because some seasons get colder than others, and there could be more precipitation in the atmosphere, which would then make it easier to calculate future rainfall, making people aware of storms that are coming ahead of time and allowing them to prepare for it (making storm water drains, etc.).
