The answer is gonna be A ecosystem
Answer:
This is because fluids have a polar nature, so they couldn´t cross the lipidic bilayer that constitutes the plasma membrane
Explanation:
Plasma membranes are contituted by lipid bilayers. These kind of compounds are hidrophobic (they reject water) and don´t permit the freely passage of hidriphilic molecules that can disolve in water, constituing fluids. Because of that cells developed transport mechanism like endocytosis.
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.
Answer:
B) expression of inappropriate gene products
Explanation:
Most of the cancers are caused when a normal gene that code for one or other proteins involved in the regulation of the cell cycle is mutated. The mutated gene may cause the production of the faulty gene products. For example, the overproduction of products of the protooncogene that push cells through the cell cycle leads to tumor formation. Likewise, when the tumor suppressor genes are not able to produce enough product to prevent progression through the cell cycle, cancer may develop.
Phosphorus. It's not abundant, but it's important. There are traces of it in our bones and in the "phospho-lipid bilayer" of the membrane.
Hope that helps!
