You have a large bottle of 2% saline solution in the lab (2% NaCl, which is sodium chloride). You need 5 ml of 0.1% saline for a

zvonat [6]

Answer:

volume of 2% saline (V₁) = 0.25ml

volume of water = 4.75ml

Explanation:

The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:

C₁V₁ = C₂V₂

where:

C₁ = initial concentration = 2%

V₁ = initial volume = ?

C₂ = final concentration = 0.1%

V₂ = final volume = 5ml

C₁V₁ = C₂V₂

calculating for V₁

∴ V₁ = (C₂V₂) ÷ C₁

= (0.1% × 5) ÷ 2%

V₁ = 0.25ml

Now, let us calculate the volume of water needed:

V₁ + Volume of water = V₂ (volume of 0.1% NaCl)

0.25 + volume of water = 5

volume of water = 5 - 0.25

volume of water = 4.75ml

Define transpiration:

Nataly [62]

Answer:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

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.
