The reason why we were unable to read the lab manual through the tubes containing isotonic and hypertonic solution is because the cells in those solutions remained intact, causing the solutions to be opaque, in the tonicity of red blood cells activity. The reason why we can't read the lab manual is because the cells in the solutions remained intact.
Cell -> tissue -> organ -> organ system -> organism
Answer:
The answer is B. It is an endothermic reaction.
Explanation:
Photosynthesis in an endothermic reaction. Endothermic reactions are all those chemical reactions that in their transformation process, in 2 or more different substances, consume Caloric Energy, in which, the products obtained possess higher energy levels, than the initial reagents, since they have taken part of the heat of the environment.
The eggs of the fluke are passed into water supplies from feces and urine of infected people. After hatching the parasite actively swims and invades the body of a snail, usually by penetrating through the snail's foot. The parasite requires the presence of certain species of snails (e.g., Oncomelania, Biomphalaria, Bulinus) to transform (and multiply) itself into an infective stage, called cercaria.
