Over 1 million species of animals have been named and described by biologists. These species arose __________. View Available Hi
yuradex [85]

Answer:

through years of evolution as natural selection shaped animal adaptations to Earth's environments.

Explanation:

Over the years, biologists have been able to successfully name more than one (1) million animal species across the world. These species arose through years of evolution as natural selection shaped animal adaptations to Earth's environments.

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

Which molecule in animal plasma membranes reduces the permeability of the membrane to most biological molecules?
kvasek [131]

Answer:

The correct answer is option 'e' : Cholesterol

Explanation:

The ease at which materials can be transported across a membrane depends on the membrane permeability. Membrane permeability is basically the ease at which materials are transported across membrane . As we know that upon increasing the viscosity of any fluid it's resistance to deformation increases or it applies a greater resisting force if we try to change the shape of the membrane thus reducing the permeability of the membrane. the increase in cholesterol increases the viscosity of the membrane thus reducing it's permeability.
