The fluid-mosaic model of membrane structure includes the following: A Option A: a lipid bilayer. B Option B: membrane proteins.
Mila [183]

Answer:

Option D

Explanation:

In 1972, the fluid mosaic model was proposed by S. J. Singer and G. L. Nicolson to describe the structure of the plasma membrane found I living cells. The model describes the plasma membrane to possess components including phospholipid, proteins and cholesterol.

The phospholipid is arranged in two layers comprising of glycerol, two fatty acids and a phosphate group. The fatty acids which forms the tail are hydrophobic (water-fearing) while the phosphate group is water-loving (hydrophobic) giving the plasma membrane an AMPHIPATHIC nature. The other component as proposed by the model are membrane proteins and cholesterol, all responsible for the fluidity of the membrane.

horrorfan [7]

Answer:

advantages of sexual reproduction:

it produces variation in the offspring

the species can adapt to new environments due to variation, which gives them a survival advantage

a disease is less likely to affect all the individuals in a population

disadvantages of sexual reproduction:

time and energy are needed to find a mate

it is not possible for an isolated individual

advantages of asexual reproduction

the population can increase rapidly when the conditions are favourable

only one parent is needed

it is more time and energy efficient as you don't need a mate

Disadvantages of asexual reproduction

it does not lead to variation in a population

the species may only be suited to one habitat

disease may affect all the individuals in a population

A species that is not native to a particular region
siniylev [52]

Answer:

A species that is not native to a particular region is called an <u>invasive species. </u>

Explanation:

In ecology, invasive species can be described as species which are introduced into an environment. These species are not native to the environment.

Introduction of invasive species in an environment can destroy a stable ecosystem. The invasive species will compete for resources like food, shelter, water etc. They might cause the extinction of the species on which they start feeding.  They might fight with predators feeding on the same prey.
