Answer:
a. more than one pathway at the same time.
Explanation:
Basically, RTK (receptor kinase receptor) principally activate many different transduction pathways about 10 or more and many cellular response in living cells.Thus, its activates more than one signal transduction pathways at once, (compare to G-protein ), and with this mechanisms it aids in coordination of some aspects of cell growth and cell reproduction .
<span>Early
investigators thought the oxygen produced by photosynthetic plants came from
carbon dioxide. In fact, it comes from water. The water plays an important role
in the production of oxygen. The oxygen that we are breathing comes from water.
In the process of photosynthesis, water would be split into oxygen, hydrogen
ions and electrons. The oxygen product would then be released by the plants.</span>
One wouldn’t allow for passive transport. And the other would allow to much. The membrane serves as a gate. Non-permeable would be a solid wall were nothing and no one can get through or get out . Including things like water. And fully permeable would represent no gate at all and would allow to much in and out of the cell.
Answer:
When cycling of matter in the ecosystems is disrupted, the whole ecosystem will be adversely affected. Matter includes living organisms such as plants, animals and microorganisms while non living things such water, air and nutrients etc. If plants are removed from the ecosystem system, then the whole ecosystem is destroyed because plants are the producer which make food for herbivores. These herbivores are eaten by carnivores and so on.
Answer:Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. ... This process (photosynthesis) takes place in the chloroplast. ... A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. ... Animal cells simply have a cell membrane, but no cell wall.
