One reason could be that there are a high number of predators killing rabbits in large quantities. Another is there may not be enough vegetation for the rabbits. They may also have a different animal competing for the same kinds of plants they eat.
Answer:
Once an organism is beyond a certain size, it cannot get essential molecules into and out of cells solely by diffusion. Diffusion is limited by the surface area to volume ratio of the organism.
1. Staphylococcus: A group of bacteria that cause a multitude of diseases.
2. Strep throat is a bacterial infection that can make your throat feel sore and scratchy.
3. Diplo refers to two cells, so diplococci are arrangements of cocci in pairs.
Answer:
Concentration gradient.
Explanation:
Diffusion may be defined as the process of the movement of solute particles down the concentration gradient. This process does not require the expenditure of energy.
The main driving force in diffusion is the concentration gradient. The molecules generally move from its region of the higher concentration towards the region its lower concentration.
Thus, the correct answer is option (3).
There are actually very few volcanoes that do not explode, but the ones that do explode with a high sound and lots of hot magma, and some are very low and don't have a lot of magma. An explosive eruption always begins with some form of blockage in the crater of a volcano that prevents the release of gases trapped in highly viscous andesitic or rhyolitic magma. The high viscosity of these forms of magma prevents the release of trapped gases.
