Answer: i think it's the first one and coexist is not in the dictionary
Answer:
D:) sunlight
Explanation:
Sunlight is one of the resources that are available in limited quantity in water bodies as compared to the land habitats since sunlight can penetrate up to a certain depth in water. However, land habitats have ample of sunlight available for plants. During early colonization of land habitats, dense forests were not present on land which in turn made even more sunlight available to the land plants of all height. Sunlight is one of the required factors to support plant growth and development.
Answer:
Graph D
Explanation:
Enzyme activity will be highest at its optimum temperature.
At temperatures far below the optimum, the enzyme does not possess enough energy to work (i.e. the molecules aren't moving fast enough because of the higher temperature to increase collisions). This is called the activation energy.
At high temperatures, the enzyme can become denatured, warping its shape and catalytic activity. This means its activity will drop quite quickly until it can no longer function.
These features are all displayed in graph D.
Answer:
c) Electron flow from ETC generates proton gradient.
Explanation:
The true statement among the given options is “Electron flow from ETC generates proton gradient.”
(As indicated to its name, electron transport chain is responsible for the transfer of electrons and eventually it triggers the protons transfer transverse the membrane. This transfer of electron creates an electrochemical proton gradient that triggers the synthesis of ATP. Hence, at certain point electron flow from ETC is responsible for generation of proton gradient.)
