Answer:

An object’s velocity will not change unless it is acted on by an external force

Explanation:

An external force changes the velocity of an object when in motion irrespective of the direction. It propels it to be in motion, hence; act as an additional force which helps to change its velocity

The graph above displays the heights of an average population of humans. Use C.E.R. (Claim, Evidence, Reasoning) to answer the f

sladkih [1.3K]

Answer:

The graph shows the height in inches of determined human population and the pattern it shows is due to the height variations that exist between individuals, due to different factors, where the average height in the population is close to 69 inches, and most of the population has heights between 67 and 72 inches.

Explanation:

The height of individuals is the measurement, from head to toe, which is made standing up and barefoot.

The graph shows the frequency of people who have a specific height, where:

Claim: According to the graph, most people are between 67 and 72 inches tall. Heights below 63 and above 72 inches are less frequent and the average person is about 69 inches tall.

Evidence: The data provided by the graph support the claim that there is variation in height in the human population. When data on anthropometric parameters are to be obtained, a sample is chosen, measured under the same conditions and then taken to a graph showing the results.

Reasoning: variations in human height respond to several factors, mainly genetic and environmental factors.

Inheritance plays an important role in determining an individual's height, although it is a polygenic pattern of inheritance, where multiple genes determine the height an individual will have.

In general, the height between men and women differs but, in addition, the inheritance of this parameter is linked to race. There is no single gene that determines whether a person will be tall or short, nor are there dominant or recessive alleles.

The combination of information from several genes will result in the phenotypic expression of height in an individual and can increases the genetic variability for this trait. It should also be taken into account that genetic disorders can affect the development of normal height.

Environmental factors and habits, especially food and family environment, are determinants of the height a particular individual will have.
