Biology

1. Which type of transport allows for the movement of large molecules, such as proteins and polysaccharides, across the cell membrane?

Correct answer: A

Rationale: Rationale: A) Endocytosis is the process by which cells engulf large molecules or particles by wrapping the cell membrane around them to form a vesicle that is brought into the cell. This mechanism allows for the movement of large molecules, such as proteins and polysaccharides, across the cell membrane. B) Exocytosis is the opposite process of endocytosis, where cells release large molecules or particles by fusing vesicles with the cell membrane to expel their contents out of the cell. C) Active transport is a process that requires energy to move molecules across the cell membrane against their concentration gradient. While active transport can move large molecules, it is not specifically designed for the transport of proteins and polysaccharides. D) Facilitated diffusion is a type of passive transport that involves the movement of molecules across the cell membrane with the help of transport proteins. While facilitated diffusion can assist in the movement of

2. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

Correct answer: A

Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.

3. Antigen-antibody binding is the principle behind:

Correct answer: A

Rationale: Rationale: Antigen-antibody binding is the principle behind vaccination. When a vaccine containing antigens (weakened or killed pathogens) is introduced into the body, the immune system produces antibodies that bind to these antigens. This binding triggers an immune response, leading to the production of memory cells that provide immunity against future infections by the same pathogen. Vaccination helps the body develop immunity without causing the disease itself, thereby protecting individuals from infectious diseases. Disinfection and sterilization involve different processes to eliminate or reduce pathogens on surfaces or objects. Antibiotic resistance is a phenomenon where bacteria evolve to resist the effects of antibiotics and is not directly related to antigen-antibody binding.

4. What is the atomic number of an element?

Correct answer: B

Rationale: The atomic number of an element is a fundamental property that defines the identity of an element. It is the number of protons in the nucleus of an atom. The number of protons determines the element's position in the periodic table and its chemical properties.

5. What is the function of the underlined phrase "with a mischievous grin" in the sentence "He approached her with a mischievous grin, his eyes twinkling"?

Correct answer: C

Rationale: The underlined phrase modifies the verb "approached" by describing his manner, making it an adverbial phrase.

6. Based on the information provided, which statement is LEAST likely to be supported by the author?

Correct answer: B

Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.
