1. What is the process of converting glucose into ATP, the cell's primary energy currency, called?

Correct answer: A

Rationale: Rationale: A) Cellular respiration is the process by which cells convert glucose into ATP, the primary energy currency of the cell. This process involves a series of biochemical reactions that occur in the mitochondria of eukaryotic cells or the cytoplasm of prokaryotic cells. Through cellular respiration, the energy stored in glucose molecules is gradually released and captured in the form of ATP. B) Fermentation is an anaerobic process that occurs in the absence of oxygen. It involves the partial breakdown of glucose to produce ATP and end products such as lactic acid or ethanol. While fermentation can generate ATP, it is less efficient than cellular respiration in terms of energy production. C) Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. This process occurs in chloroplasts and is the opposite of cellular respiration. While photosynthesis produces glucose,

2. Which of the following guidelines should be least considered in formulating objectives for

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.

3. In plant cells, what structure provides rigidity and support?

Correct answer: D

Rationale: The correct answer is D: Cell wall. The cell wall is a rigid structure found in plant cells that provides support and protection. It is composed of cellulose and other materials, forming a tough outer layer that helps maintain the cell's shape and prevents it from bursting under pressure. The cell membrane (option A) is a semi-permeable barrier that surrounds the cell but does not provide rigidity. The Golgi apparatus (option B) is involved in sorting and packaging proteins. Plastids (option C) are organelles responsible for functions like photosynthesis and storage, but they do not provide rigidity and support like the cell wall does.

4. Which of the following is a strong base commonly used in cleaning products?

Correct answer: A

Rationale: Sodium hydroxide is a strong base commonly used in cleaning products. The other choices are also bases but are not as strong as sodium hydroxide.

5. After exposure to a pathogen, the immune system develops memory. What type of immune cell is responsible for this immunological memory?

Correct answer: B

Rationale: The correct answer is A: "B cells." B cells are responsible for generating immunological memory after exposure to a pathogen. When B cells encounter a pathogen, they differentiate into memory B cells, which can quickly recognize and respond to the pathogen upon subsequent exposure. These memory B cells are crucial for mounting a faster and more effective immune response, leading to a quicker clearance of the pathogen. T cells, phagocytes, and natural killer cells play important roles in the immune response, but specifically, memory B cells are responsible for immunological memory.

6. Describe the mechanism by which genes are transmitted from parents to offspring.

Correct answer: B

Rationale: Rationale: A) Blending of parental genes, resulting in an average of their traits, is not an accurate description of how genes are transmitted. In reality, genes are not blended but rather passed down in discrete units. B) Random assortment of alleles during meiosis is the correct mechanism by which genes are transmitted from parents to offspring. During meiosis, homologous chromosomes separate, and alleles are randomly distributed to the gametes, leading to unique combinations of genes in each offspring. C) Inheritance of solely dominant alleles, masking the influence of recessive ones, is not an accurate representation of gene transmission. Offspring inherit alleles from both parents, and the expression of dominant or recessive traits depends on the specific combination of alleles. D) Direct transfer of both parental genomes, creating identical copies of the parents, is not how genes are transmitted. Offspring inherit a unique combination
