Hypertension and diabetes mellitus often occur together, and they appear to share some risk factors and causes. Lifestyle adjustments can help control blood pressure and blood sugar levels, but most people will need to follow a treatment plan for life (Barhum, 2019). Recall your learning experience related to lifestyle adjustments to prevent hypertension and diabetes mellitus through your own reading and discussions in the respective tutorial sessions and eForums. Based on the experience, develop a health reflective journal on your views and beliefs related to this issue by particularly emphasizing on the adjustment of diet and exercises.

identify the three basic requirements for efficient gas exchange in all animals. Then describe and explain why they are the basics of any gas exchange system.

if the perpendicular distance between the man's quadriceps tendon and his knee joint center of rotation remained the same (5cm), how much force would his quadriceps muscle have had to produce at this point?"

When the man's knees were at a 40 degree angle the center of mass of the man and the box was 26cm behind the knee joint center of rotation. How much torque (Nm) did this this place on his knee joint?

20) A man extends his knees as he lifts a box. When his knees reach a 80 degree angle, the center of mass of the man and the box is 20cm behind the center of rotation of his knee joint. The weight of the man (minus his lower legs and feet) is 160 pounds and the weight of the box is 40 pounds. How much torque would the mans left quadriceps muscle have to produce to maintain this position? (Hint: The man is standing on both legs. Would his left leg have to support the entire weight?)"

Tom and Alice are the parents of four children. Tom has earlobes that are not attached to the side of his head, which is a dominant trait. Alice has earlobes that are attached, which is a recessive trait. Use the two Punnett squares ("E" represents the dominant earlobe gene, and "e" represents the recessive earlobe gene) to answer the following questions.

What must be true about the earlobes of Tom's parents?

What must be true about the earlobes of Alice's parents?

Which Punnett square allows for the possibility that Tom and Alice's children have attached earlobes?

identify one disorder of the endocrine system that adults taking human growth hormone supplements could experience. List 4 symptoms of this disorder.

6. Is any ATP produced directly as electrons move down the electron transport chain? Yes or No
7. What is the name of the process, illustrated by the movement of H+ in the image above, which provides the direct source of energy to synthesize the ATP?
8. Which is the only step that ATP is produced through fermentation? b. Is this more, less or the same amount of ATP a cell would make through cellular respiration?
9. Briefly explain why fermentation is necessary for a cell to be able to continue to produce ATP through glycolysis without requiring continuing extra energy usage within the cell.

1. Using what you know about the requirements for any chemical reaction to take place, briefly
explain the need for the energy investment phase in this catabolic reaction.
2. Where did these carrier molecules come from (what previous phase(s)?
3. When the electrons are released from these carrier molecules, what else is released?
4. Is the release of electrons from these electron carriers an oxidation or reduction reaction?
5. What is formed as a product of the electron transport chain? Did the formation of this molecule involve an oxidation or reduction reaction?
