Which type of explanation would describe eating in terms of the hypothalamus affecting insulin production which affects the availability of glucose in cells?

Which type of explanation would describe eating in terms of the hypothalamus affecting insulin production which affects the availability of glucose in cells?

a) physiological

b) ontogenetic

c) evolutionary

d) functional

a) physiological

Explanation:

Physiology is one of the several branches of biology. In physiology, functions of several body parts are explained. It explains how various cells, tissues, organs and the organ systems of an organism work cooperatively to perform specific functions. For instance, the physiology of the digestive system would explain how an organism intake food which is then digested by the enzymes and juices released by several organs of this system.

Similarly, physiology explains that insulin is a hormone secreted by the pancreas. Insulin makes the body cells to absorb glucose present in the blood. The secretion of insulin is regulated by the hypothalamus. As the blood glucose level rises after digestion of carbohydrates eaten in food and the absorption of glucose in the small intestine, the hypothalamus signals the pancreas to release more insulin into the blood. This increases the availability of glucose to body cells.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
