Answer: B (gradual failure)

Explanation:

Fracture failure: This type of failure results when cutting force becomes excessive, leading to brittle fracture.

Gradual wear Gradual Failure: In this type of failure, failure is slow but progressive. As an machines becomes old, its performance and efficiency wear out gradually.

Temperature failure: This type of failure results when cutting temperature is too high for the tool material leading to the wear and tear of the machine.

Fracture and temperature failures are both immediate failure, but Gradual failure is most preferred because it leads to the longest possible use of the tool because it fails gradually.

What is the sequence of events that occur in order for the posterior lobe of the pituitary gland to release hormones into the bl
alina1380 [7]
  1. The anterior pituitary gland's endocrine cells are in contact with hormones that are released.
  2. Neurosecretory cells in the hypothalamus secrete hormones that are released.
  3. Release of a specific hormone into the bloodstream by endocrine cells in the anterior pituitary gland.
<h3>What is the main function of the hypothalamus?</h3>

Your body's sophisticated control and coordination center is located in your hypothalamus, a structure deep inside your brain. Its major job is to maintain homeostasis, a constant state of equilibrium in your body. It carries out its function through controlling hormones or by directly affecting your autonomic nervous system.

<h3>What are the endocrine cells?</h3>

The gut's endocrine cells are a significant source of the hormones that regulate metabolism, digestion, and appetite. They are mostly found in two places: islets in the pancreas and sporadic clusters in the mucosal epithelium of the gut.

Exercising causing ___________
goldfiish [28.3K]

Answer:

c. increase HDL levels

Explanation:

Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.

Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.
