Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Matter is anything that has mass. everything has matter, even the air.
Answer: because every time something eats something 10% of the energy is passed on so it starts as 100% with plants photosynthesizing then the herbivore gets 10% of that energy. The carnivore that eats the herbivore gets 10% of the herbivore’s energy so by the time it gets to the top of the pyramid there is less and less energy to consume.
BMI is the calculation based on a person's weight and height.
Answer:
It helps insure the survival of a species in a whole.
Explanation:
Allows different species, for example dolphins or meerkats, to mate and ensure survival in their habitats.
