Answer:

Our ear consists of

1 Outer ear (pinna) which passes through auditory canal leading to the ear drum (tympanum)

2 The middle ear consists of three tiny bones malleus, incus and stapes. the three bones are collectively called ear ossicals.

3 Inner ear or membranous labyrinth has two main parts-- cochlea and spiral-shaped, and semicircular canals.

The pinna collects the sound waves and conducts them through the external auditory canal. They finally strike on the ear drum which is set into vibration.

hope it helps you....

It is the filtration process in which blood is filtered and the nitrogenous waste and water moves inside the glomerulus.

Tubular reabsorption -

In this process, the molecules and ions gets reabsorbed into the circulatory system.

Tubular secretion -

The secretion process in which , substances like hydrogen ions , creatinine and drugs are removed from the blood and collected in the duct.

And the end product of this is the Urine.

Bezzdna [24]

The given question lacks the important part of the question required to answer it, however, the complete question is as follows:

Kyle is 30 years old, weighs 125 pounds, and is 72 inches tall.

Use the formula and chart below, as well as a calculator, to evaluate his weight, and then answer the question.

BMI = Weight (in pounds) ÷ [Height (in inches)]² x 703

BMI categories, general

Underweight: less than 18.5

Normal weight: 18.5-24.9

Overweight: 25-29.9

Obese: 30 or greater

Given Kyle's BMI, which statement is most likely true of Kyle's health risks?

a.high risk of diabetes and kidney disease

b. possible risk of malnutrition

c. no risk based on weight

Answer:

The correct answer is : option B. possible risk of malnutrition

Explanation:

Given:

age : 30

weight : 125 lbs

height: 72 inches

formula:

BMI = Weight (in pounds) ÷ [Height (in inches)]² x 703

solution :

by the formula, BMI of Kyle would be:

BMI = Weight (in pounds) ÷ [Height (in inches)] ² x 703.

=125/5184 x 703 = 16.95

Comparing BMI with the given chart suggests 16.95 is underweight and probablely cause due to the malnutrition or may be cause to malnutrition as underweight is breeding ground for malnutrition problems.

Thus, the correct answer is : option B.
