Answer:
The correct answer is it occurs naturally by diffusion.
Explanation:
Diffusion is one of the most important passive transport mechanism which helps in the movement of small molecules and gases across the plasma membrane down their concentration gradient.
In simple words diffusion deals with the transport of small molecules and gases from the region of high concentration to the low concentration region untill the contration of both the regions become equal.
Answer:
D
Explanation:
It can't be A as nuclei must be positive.
It can't be B as nuclei must contain at least one proton, and no electrons.
Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.
Answer:
The correct answer will be- will be called "Clones" with no genetic variation thus result in less adaptability to environment.
Explanation:
Plants can reproduce by both modes of reproduction called asexual and sexual reproduction. The asexual mode of reproduction produces genetically similar offsprings in less period of time and thus helps in spreading of the species in minimum time as in the case of Kalanchoe.
The Kalanchoe can dominate a large area of the habitat using this mode of reproduction but at the cost of genetic variation.
Since asexual reproduction results in Clones with same genetic material so the descendants of the plant will be less adaptive to changing the environment as asexual reproduction does not involve genes.
