Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.
This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.
The human activities that could have endangered botana curus is:
Pollution: It lead to slow down the rate of growth of the plant.
Overexploitation: The over use of plant for its medicinal purpose.
Habitat: The natural habitat of the plant has been changed due to various human activities.
The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent
The answer is The ions are protected inside the lipid bilayer so that it is not pushed back to a more polar environment.
The lipid bilayer is mainly composed of lipids (phospholipids and cholesterol), and is also composed of proteins such as transporters.
The ions (which are polar) can not cross directly through the lipids because they will repel them due to their apolarity. On the other hand they can easily pass through protein channels that will protect them during their passage (the proteins are more polar than lipids).
A constant stream of charged particles flowing away form the sun
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
