The chloroplasts had inner membrane
Explanation:
The primitive photoautotrophs utilized hydrogen sulphide as the electron donor to perform photosynthesis for energy production.
Later upon understanding the endosymbiotic relationship of cyanobacteria which resided in the mitochondria of a eukaryotic host cell, the use of chloroplasts for photosynthesis was understood.
Generations after generations led to the development of chloroplasts by the cyanobacteria due to this symbiotic relationships which developed into the chloroplasts.
The unique presence of the inner membrane and its components like the stroma, thyllakoids helped the organism to utilize water as the electron donor for photosynthesis like the present day eukaryotes. This is the main reason why cyanobacteria is considered as the ancestor for eukaryotes.
Answer:
Small intestine, liver, bile and lipase.
Explanation:
Digestion of fat occurs in the small intestine. Its digestion occurs with the help of bile, that is made in the liver. Bile breaks the fat into small drops that are easier for the lipase enzymes to change it. Lipase enzymes is a type of enzymes that works only on lipids and lipids are broken down into fatty acids and glycerol. These substances are absorbed by our body and used it for producing ATP for the body.
<span>The best method used to prevent soil depletion would be contour farming.
In contour farming, the land is tiled in consistent elevation. Contour farming is efficient in reducing soil depletion because it can conserve rain water and reduce the erosion of soil.
If there is no contour farming in your option, then choose A. Adding fertilizer. </span>
Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
