Answer:
The action of the shifting continental plates of Earth has important effects on the course of speciation of living organisms by reproductively isolating populations or allowing previously separated populations to interbreed..
Explanation:
The formation of geological barriers such as mountains special cause of allopatric type, these barriers cause isolation which prevents two or more groups from mating each other regularly and finally there is speciation. On the other hand the movement of continental masses for example can cause the union of islands that allows a new genetic crossing between populations.
Answer:
This question lacks options, the options are:
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules
The answer is B
Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
I think its A because plants need sunlight to produce its sugars.
Energy just exists.
It goes from one thing to another. It never dies out.
We get our energy from the burning mass of the energy ball that we call the sun.
Answer:
yes because their traits can combine and create a different trait i think that is why but i know for sure that the offspring can have different traits from their parents
