Answer:
B. From 200 m to the surface
Explanation:
Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.
In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.
Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.
Answer: 6,000/30 = 200, so 200 molecules are required.
Explanation:
The correct answer is "profound red cell hemolysis"
An Rh negative mother that has been sensitized means that the mother developed anti-Rh antibodies therefore these antibodies will attack the red blood cells of the Rh positive fetus as this fetus has the Rh antigen on his or her red blood cell. This will cause profound red cell hemolysis.
Answer:Self-assembly into a simple membrane
Explanation:
The cell membrane is the biological membrane that separates the interior of the cell to the exterior of the cell.
The cell membrane is made of lipid by-layer. The first cell membrane was made of lipids. It is so because it has the ability to assemble and form a membrane like structure.
It helps in entry and exit of the substances from inside of the cell to outside and vice versa.
