Concept explainers
Eukaryotic cells consist of several organelles, including Golgi complex, mitochondria, endoplasmic reticulum, flagella and cilia, chloroplast, microfilaments and microtubules, and lysosomes. The key reaction happening in the mitochondrion is

PLEASEEEEEE HELP MEarrow_forwardQ4: What is the antibiotic that is used in this experiment presented in the Antibiotic-Resistant Bacteria Connect Activity? Penicillin Streptomycin E. coli Agar Q11: According to the Connect activity, analogous structures do not offer evidence of evolution. However, the presence of analogous structure in two organisms does actually provide us with information about their ancestory. What is this information? the organisms share a common ancestor prior to the evolution of the structure the organisms share a common ancestor after the evolution of the structure the organisms can share no common ancestor.arrow_forwardPls help ASAParrow_forward

The mechanisms underlying the rapid evolution of drug resistance are, however, poorly understood. The heterogeneity of the environments in which bacteria encounter antibiotic drugs could play an important role. E.g., in the highly compartmentalized human body, drug levels can vary substantially between different organs and tissues. It has been proposed that this could facilitate the selection of resistance mutants, and recent experiments support this. To study the role of spatial heterogeneity in the evolution of drug resistance, we present a quantitative model describing an environment subdivided into relatively isolated compartments with various antibiotic concentrations, in which bacteria evolve under the stochastic processes of proliferation, migration, mutation and…arrow_forward
