Answer: Skinfold testing
Explanation:
Skinfold testing, is also referred to as calliper testing and it's used to know the body fat percentage. Skinfold testing is an inexpensive, portable, and common way to assess body fat in the fitness industry.
It is typically done with the use of caliper tapes, marker pens which makes it cheap. Skinfold testing isn't usually accurate which is as a result of human errors.
A a healthy diet and exercise have an impact on the overall health of
the body. While your digestive and respiratory systems seem very
separate in their activities, in reality, the systems work together in
several ways. Which of these correctly pairs a body system with it's
function? All BUT ONE may apply.
Answer:
This would be answer choice A
The digestive system breaks large nutrient molecules into smaller ones that are absorbed into the bloodstream. So, the correct option is A.
What is meant by metabolism ?Metabolism is defined as the mechanism of the body by which the energy is produced from the food we eat, through some chemical reactions.
Here,
The overall proper health of the body is attained through having proper diet and regular exercise. In order to maintain the health, several physiological activities occurs in our body simultaneously.
Metabolism is one of the main physiological mechanism in our body, by which the food we eat is being converted into energy which is necessary for the growth and proper functioning of our body cells and organs.
Digestion is the important process of metabolism.
Digestion is the process by which the large, insoluble food molecules we consume, are broken down into smaller, water-soluble molecules, so that it can be easily absorbed into the blood plasma.
The different steps of digestion are ingestion, propulsion, mechanical digestion, chemical digestion, absorption and defecation.
Hence,
The digestive system breaks large nutrient molecules into smaller ones that are absorbed into the bloodstream.

A block slides across a flat, horizontal surface to the right. For each choice, the arrows represent velocity vectors of the block at successive intervals of time. Which of the following diagrams represents the situation in which the block loses kinetic energy?
The diagrams the question refers to is in the attachment.
Answer: Third diagram or alternative C.
Explanation: In physics, vector is a representation of magnitude and direction.
Kinetic Energy is energy made by a moving object, i.e., when an object with mass has velocity, it also has Kinetic Energy. It's calculated as:
[tex]K=\frac{1}{2}mv^{2}[/tex]
Vectors below are representing change in velocity during intervals of time.
In the first diagram, vectors doesn't change, so velocity and kinetic energy are constant.
At the second, velocity still constant, however, the "intensity" of the arrow is weaker than the first, which means velocity is less than the first diagram and so is its kinetic energy.
In the fourth diagram, the arrows grow bigger from left to right. This means velocity increases during time. If velocity grows bigger, so does kinetic energy.
In the third diagram, the arrows decrease as it goes to the right: the block's velocity decreases during the successive intervals, which means, kinetic energy diminishes through the interval.
Thus, diagram C represents the situation in which the block loses kinetic energy.
