Which of the following statements is not true about body composition? a. Too much body fat can lead to joint or bone disorders. B. Body composition is influenced by numerous factors. C. Body composition refers to a person's overall weight. D. Lean body mass is the nonfat component of body composition. Please select the best answer from the choices provided. A b c d.

Answers

Answer:

Too much body fat can lead to joint or bone disorders.

The statement that is incorrect is body composition refers to a person's overall weight. The correct option is C.

What is body composition?

The relative proportions of fat, muscle, bone, and other tissues in the human body are referred to as body composition.

It is a measurement of how much of a person's body weight is made up of fat, lean tissue (like muscle and bone), and other types of tissues.

Body composition, rather than a person's overall weight, refers to the relative proportions of fat and non-fat mass (such as muscle, bone, and organs) in the body. As a result, option C regarding body composition is false.

Option A is correct because excess body fat can put extra strain on joints and bones, resulting in joint or bone disorders.

Option B is correct because body composition is influenced by a variety of factors, including genetics, age, gender, diet, and physical activity.

Thus, the correct option is C.

which of the following situations describe exponential growth? check all of the boxes that apply. the number of butterflies in an area increases by 10% per year. the population of a city increases by 500 people per year. kristy bought a collector’s coin for $2.15 and its value increases at a rate of 3% per year. the number of people who have heard a rumor increases because every person tells 2 other people.

Answers

The situations that describe exponential growth are;

1 ; The number of butterflies in an area increases by 10% per year.

3; Kristy bought a collector’s coin for $2.15 and its value increases at a rate of 3% per year.

4; The number of people who have heard a rumor increases because every person tells 2 other people.

Exponential growth generally can be represented by the formula;

f(n) = a(1 + r)ⁿ

where;

f(n) = exponential growth function

a = initial amount

r = growth rate in %

n = number of time intervals

1) The growth rate of the butterflies increase by 10% every year;

This can be modelled by an exponential growth function because we are given growth rate.

2) The population of a city increases by 500 people per year; This can't be modelled by exponential growth function because the growth rate is not in percentage.

3) Kristy bought a collector’s coin for $2.15 and its value increases at a rate of 3% per year;This can be modelled by an exponential growth function because we are given growth rate in %.

4) The number of people who have heard a rumor increases because every person tells 2 other people; This can be modelled by an exponential growth pattern because the rate of increase is 2 for every one person which is exponential in nature.

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. The only problem is that you do not know what element will form. By your previous calculations you know that you will have 6. 3 moles of product. When it is complete, you weigh it and determine you have 604. 4 grams. What element have you produced?.

Answers

Answer:

molybdenum (Mo)

Explanation:

For this question you need to understand what the concept of molar mass is.

Molar mass is the exact mass by which you will obtain a mol of that specific element. For example the molar mass of H2O is 18g/mol, so it means that in 18 grams of water, you exactly have 6.022x10²³ molecules of water or one mole.

So here you know the number of moles you produce and its conversion to grams. The problem is basically stating that in 604.4 grams of x element you have 6.3 moles of that element.

All you have to do is divide the number of grams by the number of moles:

604.4grams/6.3 moles=95.94 g/moles,

You obtained the molar mass of that X element, and in fact the molar mass corresponds the molecular mass of all elements, that is an information provided by the periodic table. So all you have to do is look for the element with a molecular mass of 95.94 uma or a very close approximate.

Molybdenum has a molecular mass of 95.95. So that's the answer.

Which ion/molecule in the saliva allows you to taste sugar as sweet weegy.

Answers

Saliva is made up of 99% water, the water molecules helps dissolve food and allows to perceive flavors through the sense of taste.

The food that is introduced into the mouth is dissolved in the saliva, penetrating the taste buds through the pores in the tongue.

The aqueous content where the water molecules represent more than 99% allow the taste receptors to be reached and there is ion exchange for the flavor to be captured.

The individual molecules to perceive the sweet taste are released after moistening the food with saliva, this function is determined by the water.

Therefore, we can conclude that saliva acts on the taste function since the water content can determine the level of dilution of basic flavors such as sweet.

The life span of a battery is the amount of time the battery will last. The distribution of life span for a certain type of battery is approximately normal with mean 2. 5 hours and standard deviation 0. 25 hour. Suppose one battery will be selected at random. Which of the following is closest to the probability that the selected battery will have a life span of at most 2. 1 hours?.

Answers

The probability that the selected battery will have a life span of at most 2.1 hours is 5.48%.

z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x\ is\ raw\ score, \mu\ is\ mean,\sigma\ is\ standard \ deviation[/tex]

Given that μ = 2.5, σ = 0.25.

For x < 2.1:

[tex]z=\frac{2.1-2.5}{0.25}=-1.6[/tex]

From the normal distribution table, P(x ≤ 2.1) = P(z < -1.6) = 0.0548 = 5.48%
