Answer:
A. Some were already resistant and were the survivors that could reproduce
Explanation:
Both resistant and susceptible insects will be exposed to DDT, but according to the evolution theory, it is expected that those insects that are resistant to the insecticide will be selected by natural selection. In consequence, the resistant individuals will survive to reproduce in the next generation.
Lean persons may acquire a lipid profile with raised LDL- and HDL-cholesterol levels and reduced triglycerides when they follow carbohydrate-restricted diets (CRDs) (TGs). This lipid profile's intensity is correlated with BMI, therefore people with lower BMIs show greater rises in both LDL-C and HDL-C. Lean Mass Hyper-Responders (LMHR) is a subset of people who, while having normal pre-diet LDL-C, as shown by the inverse relationship between BMI and changes in LDL-C and HDL-C on CRD, respond to weight loss by increasing their HDL-C and LDL-C levels. revealed a substantial hyperlipidemic response to a CRD, with mean LDL-C and HDL-C levels rising to 320 and 99 mg/dL, respectively, in the context of mean TG of 47 mg/dL, as opposed to non-LMHR (mean values of 148 and 145 mg/dL, respectively). Again, with very normal pre-diet LDL-C and the absence of genetic evidence suggestive of familial hypercholesterolemia in those who have been examined, some LMHR may have LDL-C levels above 500 mg/dL.With carbohydrate restriction in lean individuals, the increased dependence on fat as a metabolic substrate drives increased hepatic secretion and peripheral uptake of TG contained within very low-density lipoproteins (VLDL), resulting in marked elevations of LDL-C and HDL-C and low TG, according to the Lipid Energy Model (LEM), which aims to explain this metabolic phenomenon. Here, we go through the LEM's main characteristics. We examine various lines of existing research that support the model and make recommendations for how to test its predictions.

Answer: Hope this helps!
It is useful to use light years when you have to measure a super long distance as a light is approximately 6 trillion miles. And astronomical units are known as measurements within our solar system.
The rotation of Earths axis and the tides of the ocean are what cause the daily cycles of our World.
Plants are living things because they are made of living cells and exchange gases with the air around.
