The endocrine system is responsible for maintaining homeostasis of the body via rapid transmission of electrical signals. This system is the group of glands that are responsible of producing hormones that functions to regulate growth and development, metabolism, tissue function, sleep, reproduction and other processes in the body. The glands are being controlled by stimulation of the nervous system and by the chemical receptors that are in the blood. It consists of the thyroid gland, parathyroid gland, pituitary gland, adrenal gland, ovaries for females and testicles for males and the pancreas. This system affect almost all of the organs and cells in the body.
Answer:
A
Explanation:
A. The optimum pH of the enzyme is 6.6. - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)
B. The optimum pH of the enzyme is 5.8. - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80
C. The enzyme's activity is greater around pH 8.0 than around pH 5.0 - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.
D
. The enzyme's activity continually increases as pH increases from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.
Answer:
convergent evolution.
Explanation:
When organisms of distantly related species or groups are found in similar environmental conditions, they develop some similar features which are otherwise not present in their ancestral species. This is called convergent evolution. Convergent evolution also results in the development of similar traits in the distantly related organisms that are found in distantly located geographical regions having similar environmental conditions. Therefore, the presence of the same features in rodents and flying squirrels represent convergent evolution.

The two European countries that were the biggest winner in the race to seize African colonies were BRITAIN AND FRANCE.
In the early 18th century, seven different European countries held African colonies, of these seven, Britain and France were the biggest holders. The major reason reason behind the colonization is the empowerment and the advancement of the colonizing countries. It was only two African countries, Ethiopia and Liberia that remain uncolonized during this period.
