1. Pseudoscience and nonscience differ in that:
A. nonscience is not valuable and pseudoscience is valuable.
B. pseudoscience deceives, misleads, or misinforms and this is not a primary characteristic of nonscience.
C. nonscience forms hypotheses and pseudoscience does not.
D. pseudoscience has led to major changes in intellectual thought and nonscience has not.
is it B
2. Metabolism refers to:
A. chemical reactions such as photosynthesis.
B. the process of reproduction.
C. the formation of heterotrophs.
D. a collection of hypotheses.
im confused between A n D

is it D

For question 1, to determine the correct answer between options A, B, C, and D, we need to understand the difference between pseudoscience and nonscience. Pseudoscience refers to claims, methods, or practices that are presented as scientific but lack scientific evidence or validity. It often involves deception or misinformation. On the other hand, nonscience refers to subjects or areas that are not within the scope of scientific study.
Option B states that pseudoscience deceives, misleads, or misinforms, which is a primary characteristic that distinguishes it from nonscience. This is an accurate explanation of the difference, so yes, the correct answer is B.
For question 2, we need to determine the correct definition of metabolism. Metabolism refers to the chemical reactions that occur within an organism to convert food into energy or building blocks for growth, repair, and reproduction.
Option A states that metabolism refers to chemical reactions such as photosynthesis. However, photosynthesis is a specific metabolic process in plants, not metabolism as a whole. Therefore, option A is not the correct answer.
Option D states that metabolism is a collection of hypotheses. This is incorrect, as metabolism is a biological process, not a collection of hypotheses. Therefore, option D is not the correct answer.
Based on the explanation above, the correct answer is not A or D.
For question 3, we need to arrange the levels of organization from simple to more complex.
Option A lists levels of organization starting from the biosphere, ecosystem, community, and population. This order is from larger to smaller scales, so it does not follow the sequence from simple to complex. Therefore, option A is not the correct answer.
Option B lists levels of organization starting from atoms, cells, molecules, tissues, and organisms. This sequence is correct, as it starts from the simplest unit (atoms) and progresses to more complex structures. Therefore, option B is the correct answer.
Therefore, the correct answer is option B for question 3.
