Answer: Option E) the products have less potential energy than the reactants
Explanation:
Though the actual graph is not displayed, but, whenever reactants occupy a position higher than the product on the graph of reaction coordinate vs time taken, it means the reactants (AB+CD) have molecules with higher energy bonds than the products AC +BD
Thus, the reaction of AB + CD to yield AC+BD will occur spontaneously with the release of energy.
Eukariotic cells have nuclei, while prokaryotic cells do not.
Answer:
The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.
Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.
For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.
In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.
Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
Hello! Your answer would be C, They regulate body temperature through behavioral mechanisms.
An endothermic animal is one which is capable of maintaining its own body temperature. They do this through physiological mechanisms, which is what the last choice is saying - these involve things such as hormones, sweating, etc.
These endothermic animals are considered warm blooded. This is because they can make their own body heat. Humans and other mammals are endothermic. We generate our own heat - we don't rely on sunbathing or shade to cool down or heat up our <u>internal</u> body temperature.
Hope this helps!
I would go with 4 that's what makes the most sense to me, and i just learned about this last year so... I hope this helps good luck..
