Through the use of a light microscope it is possible to observe in multicellular organisms different types of cells and organelle features, and in general, they are all very small.

They are all those forms of life whose bodies are composed of a diversity of cells organized, hierarchical, at the cellular level through organelles that are specialized cell differentiations.

The cells that make up these organisms have different shapes and sizes and, in general, they are all very small, so to see them it's needed a light microscope, an instrument that increases many times the size of samples.

Therefore, we can conclude that through the use of a light microscope it is possible to observe in multicellular organisms different types of cells and organelle features, and in general, they are all very small.

Answer:

There are 1.806×10²⁴ atoms in 3 moles of iron.

Explanation:

Step 1:

Data obtained from the question

Number of mole of Fe = 3 moles

Number of atom =?

Step 2:

Determination of the number of atom.

From Avogadro's hypothesis, we understood that:

1 mole of Fe = 6.02×10²³ atoms

Therefore,

3 moles of Fe = 3 × 6.02×10²³ atoms

3 moles of Fe = 1.806×10²⁴ atoms

Thus, 3 moles of iron, Fe contains 1.806×10²⁴ atoms.

The graph of the normal distribution of the random sample size of 24 will have the shape of a bell curve.

The value of k such that P(-2.069 < T < k) = 0.965 is 2.5

The sample size is given as:

n = 24

This means that the degrees of freedom is:

df = n - 1

df = 24 - 1

df = 23

The probability is given as:

P(-2.069 < T < k) = 0.965

This can be rewritten as:

P(T>-2.069) - P(T>k) = 0.965

The value of P(T>-2.069) at a degrees of freedom of 23 and [tex]\alpha[/tex] = 0.025 is 0.975

So, we have:

0.975 - P(T>k) = 0.965

Collect like terms

P(T>k) = 0.975 - 0.965

Evaluate the difference

P(T>k) = 0.01

The value of k that makes P(T>k) = 0.01 is 2.5.

So, we have:

k = 2.5

Hence, the value of k is 2.5

The expected value of a car worth $25,000 after 5 years will equals to $11,093.

[tex]A = P (1 + r/n)^ni[/tex] where p = $25,000, r= 0.15, i = 1, i = 5

A = 25000* (1 + -0.15/1)^5*1

A = 25000*(0.85)^5

A = 25000*0.4437053125

A = 11092.6328125

A = $11,093

Hence, the expected value of a car worth $25,000 after 5 years will equals to $11,093.

Based on the number of years, and the number of nesting sites, the exponential function that best models the data is B. n(x) = 46,797(0.93)ˣ.

You can find the correct function by testing out the options with the given x value to see if it correctly predicts the number of nesting sites.

Function n(x) = 25,956.80(1.08)ˣ

Assuming x is 3:

= 25,956.80(1.08)³

= 32,698 sites

This function does not predict the correct number of sites which is 40,513.

Function n(x) = 46,797(0.93)ˣ

Assuming x is 3:

= 46,797(0.93)³
