Question 1

Refer to Figure 2.2. What is the atomic number of the atom shown, and what element does it represent?

Accepted Answer

Atomic number is 6; element is carbon.

Question 2

Based on Figure 2.3, which type of chemical bond is most likely to form between the two atoms shown, and why?

Accepted Answer

An ionic bond, because one atom can donate electrons to the other to achieve stability.

Question 3

Figure 3.2 shows a cell placed in a solution. Based on the appearance of the cell, what type of solution is it in?

Accepted Answer

Hypotonic solution

Question 4

Examine Figure 3.3. What type of tissue is depicted, and what is its primary function?

Accepted Answer

Stratified squamous epithelium; protection against abrasion

Question 5

In Figure 4.2, the arrow is pointing to a membrane surrounding the lung. What is the name of this membrane?

Accepted Answer

Parietal pleura

Question 6

Refer to Figure 2.2. How many electrons are present in the outermost shell of this atom, and what does this imply about its chemical reactivity?

Accepted Answer

Six electrons; the atom is likely to form four covalent bonds.

Question 7

In Figure 2.3, if the atom with 3 protons loses one electron, what will be its resulting charge?

Accepted Answer

$$+1$$

Question 8

Figure 3.2 shows a cell swelling and bursting. What process is responsible for this, and what is the direction of water movement?

Accepted Answer

Osmosis; water moves into the cell

Question 9

Based on Figure 3.3, which feature distinguishes this tissue as stratified squamous epithelium?

Accepted Answer

Presence of multiple layers with flattened cells at the surface

Question 10

In Figure 4.2, what is the function of the membrane indicated by the arrow?

Accepted Answer

To reduce friction between the lungs and chest wall during breathing

Question 11

Refer to Figure 2.2. What is the atomic mass number of the atom shown?

Accepted Answer

$$12$$

Question 12

In Figure 2.3, what is the total number of electrons in the atom with 9 protons, and what element does it represent?

Accepted Answer

9 electrons; fluorine

Question 13

Figure 3.3 shows a tissue with multiple layers of cells. Which region of this tissue is most likely to undergo mitosis?

Accepted Answer

The basal (deepest) layer

Question 14

In Figure 4.2, what type of fluid is found between the two layers of the membrane indicated by the arrow?

Accepted Answer

Serous fluid
