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.
The best answer is: introducing exotic species into
<span>
new environments. This can be actually bad, as new species can actually reduce the biodiversity in the environments to which they're introduced</span> , such when cats hunt indigenous birds.
I was a bit thinking about the last option too: making sure local people benefit from conservation efforts.
This is not one of the classical goals of the conservation efforts, but since the previous one is definitely correct, i don't this one is. (it's not that it's not a goal, but it isn't a main focus)
2and3 only are the defense
Answer:
Cells, Tissues, Organs, Organism
I hope this helps!
Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms.
<h3>Mendel's Experiments</h3>
Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.
From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.
Mendel noted traits can be divided into dominant and recessive phenotypic characteristics.
Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.
