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’m not sure of my answer I think it’s false
<span>Because by the time it burns it self out, in a couple billion years, it won't matter. The fact that it will destroy the earth at this point also makes it not matter</span>
Cyanobacteria are primitive organisms where chloroplasts are believed to be originated. These phototrophic organisms benefit the environmental and the clinical aspects because of their unique physiology. For instance, they contribute to energy attainment from sunlight which helps other organisms gain energy when this is consumed. Another is the contribution to biogeochemical cycles. And lastly, how these can aid in many medical discoveries and treatments.
Answer:
B. Black Squirrels have a survival advantage over gray squirrels
Explanation:
Using the information provided, it can be inferred that there is a difference between how many Gray squirrels and how many Black squirrels are being naturally selected.
This means:
Black squirrels have an advantage that reduces the amount of squirrels being selected from their environment.
Hope this helps!
