Answer:Under a microscope the cells of mushrooms, plants, and animals all have visible nuclei animals, because both animals and fungi have to consume living things to get energy and nutrients, whereas, plants use sunlight to make their food.
I would say option A, when a drug kills most of the bacteria the ones left to breed are those that have a natural resistance to the drug.
<span>Nervous System - Nucleus - control (responding to certain neurotransmitters by allowing transcription factors to be formed)
Respiratory System - Plasma Membrane (alveoli allow certain particles into the cells but want to keep contaminants out)
Reproductive System - Nucleus - DNA (determines in part the genome and developmental process of the offspring)
Digestive System - Mitochondria (want full redox reaction to occur in the organelle based on nutrients extracted from food)
Integumentary System - Cytoskeleton (for support as well as in the construction of the basal lamina)
Musculoskeletal System - Endomembrane System (think about the sarcoplasmic reticulum and the effect of increased surface area when calcium is released)
Circulatory System - Passive Transport (through capillaries especially)</span>
