Answer:
Algae produces food and catfish also needs warm water.
Explanation:
Sunlight regulates the productivity of algae and the number of catfish in a pool because algae produces food in the presence of sunlight during the process of photosynthesis. If algae produces more food, so more food is available for the catfish and as a result the population of catfish increases. If no sunlight occur on the pool the algae is unable to produce food and the population of catfish decreases. Sunlight increases the temperature of water which makes environment suitable for the catfish because catfish needs slightly warm water for its growth. So we can say that sunlight has a great affect on algae and catfish.
Answer:Either the cell wall or the membrane
Explanation:
The cell wall proctects the cell while the membrane forms structures inside of the cell
Answer:
Explanation:
Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.
During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called chromatin.
In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides.
<span>If the krebs cycle enzymes are only produced in the mitochondria of eukaryotic cells, but throughot the cytosol of bacteria, does that mean that mitchondria are the evolutionary legacy of early eukaryote ancestors engulfing bacteria which became symbiotic?</span>
