Answer:
Insulin is an hormone that keeps blood glucose levels from getting too low or too high. After digestion, insulin is released from the pancreas into your bloodstream. What systems are involved in maintaining blood sugar levels?
Circulatory and Endocrine
Explanation:
Circulatory and Endocrine are the ones involved in maintaining blood sugar levels where the endocrine secrets the hormone while the circulatory ensure the delivery to the targeted organ or part of the system
Answer:
The correct answer is (a). The brown beetle migrated to island #1 and gave rise to the colored species on island #2 through adaptive radiation.
Explanation:
As there are no brown beetles on the island 1, and island 2 has less biodiversity of plants, it's possible to think that the brown beetle migrated to island 1 where there are many kinds of different plants, which would lead to the adaptation of these organisms resulting in many different species.
Answer:
Digestion including hydrolysis
Explanation:
In the process of digestion, bigger food molecules are broken down into smaller macro molecules. These macro-molecules in later stage are absorbed or accumulated by cell and further broken down to release energy. It is during the process of hydrolysis,
Where big macro-molecules are broken into smaller polymers and further into monomers thereby releasing energy. This chemical process is assisted by an enzyme in the presence of water molecules.
Answer:
The correct answer is B. Worms move through changes in body structure caused by contraction of muscles compressing their watery fluid.
Explanation:
The hydroskeleton consists of a fluid-filled cavity, surrounded by muscles. The fluid pressure and the action of the muscles that border it, serve to change the body's shape and produce a movement such as digging or swimming. The successive contraction of various metamers, which are provided with bundles of circular and longitudinal muscle fibers, stretching and thickening parts of the body, allow it to move horizontally. Hydrostatic skeletons have a role in the locomotion of annelids, nematodes and other invertebrates. The hydroskeleton has similarities with the hydrostatic muscles.
