4. How do current levels of plant and animal biodiversity on Easter Island compare with past biodiversity levels?
shtirl [24]

Answer:

The Easter Island once used to be extremely diverse in biodiversity. It had abundant amount of plant and animal species living there.

Biodiversity in the past was extremely high due to favorable conditions there. The temperature and climate of Island was favorable for the growth of plants and animals.

It has mild climate with fertile soil which favored growth but now the scenario is different as it is now barren land with lots of sand and no diversity among plants and animal species is found there.

Explain the method of passive transport that moves molecules across the plasma membrane of a cell
ElenaW [278]
Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
