what type of tissue connects bones to other bones

ATI TEAS 7

Practice Science TEAS Test

1. Which type of tissue connects bones to other bones?

A. Tendons
B. Ligaments
C. Cartilage
D. Muscle

Correct answer: B

Rationale: Ligaments are the correct answer. Ligaments connect bones to other bones, providing stability in joints. Tendons, on the other hand, connect muscles to bones, allowing movement. Cartilage is a type of connective tissue that cushions joints and helps with smooth movements. Muscle tissue is responsible for generating force and movement in the body, not for connecting bones to each other.

2. Cartilage, found in joints and the ear, is a type of:

A. Epithelial tissue
B. Connective tissue
C. Muscle tissue
D. Nervous tissue

Correct answer: B

Rationale: Cartilage is a type of connective tissue that provides support and flexibility to various parts of the body, such as joints and the ear. It is composed of cells called chondrocytes embedded in a matrix of collagen and proteoglycans. Epithelial tissue covers body surfaces, muscle tissue is involved in movement, and nervous tissue transmits signals. The correct answer is connective tissue because cartilage serves a supportive function in the body.

3. Which of the following is an example of a salt?

A. Sodium hydroxide (NaOH)
B. Hydrochloric acid (HCl)
C. Sodium chloride (NaCl)
D. Sulfuric acid (H₂SO₄)

Correct answer: C

Rationale: Sodium chloride (NaCl) is an example of a salt. Salts are ionic compounds formed by the reaction of an acid with a base. In this case, sodium chloride is formed by the reaction of sodium hydroxide (a base) with hydrochloric acid (an acid). Sodium hydroxide (NaOH), hydrochloric acid (HCl), and sulfuric acid (H₂SO₄) are not salts because they are not formed by the neutralization reaction of an acid and a base, which is a characteristic of salts.

4. Which type of cell secretes antibodies?

A. Bacterial cells
B. Viral cells
C. Lymph cells
D. Plasma cells

Correct answer: D

Rationale: The correct answer is D: Plasma cells. Plasma cells are a type of white blood cell that secretes antibodies. Antibodies are essential components of the immune system, as they help in identifying and neutralizing pathogens. Choice A, B, and C are incorrect as bacterial cells and viral cells do not secrete antibodies, and lymph cells are involved in the immune response but do not secrete antibodies like plasma cells.

5. The adaptive immune system has two main branches: humoral and cell-mediated immunity. Which type of immune cell is primarily responsible for antibody production?

A. Helper T cells
B. Cytotoxic T cells
C. B cells
D. Natural killer cells

Correct answer: C

Rationale: B cells are primarily responsible for antibody production in the adaptive immune system. When activated, B cells differentiate into plasma cells, which are specialized to produce antibodies. Helper T cells play a crucial role in activating B cells, but they do not directly produce antibodies. Cytotoxic T cells are involved in cell-mediated immunity by killing infected cells, while natural killer cells are part of the innate immune system and target virus-infected and cancerous cells. Therefore, the correct answer is C (B cells) as they are directly involved in the production of antibodies, essential for humoral immunity.
