how enzymes inhibitions studies in the formulation and development of drugs
Answers
Answer:
Enzyme inhibitors may alter the elimination rate of a particular drug or inhibit detoxication pathways
Explanation:
An enzyme inhibitor is a chemical compound capable of binding to an enzyme in order to reduce its activity. An enzyme inhibitor may bind to an active site and thus decreases the rate of reaction (direct inhibition). Enzyme inhibitors may act 1-to Inhibit detoxification enzymes and 2-reduce the elimination rate of enzyme drugs, thereby having dose-dependent toxicity effects. For example, many medicines are based on the inhibition of Cytochromes P450 (CYPs) proteins, which are a superfamily of enzymes required for drug metabolism.

Do you think this indicates that humans are the pinnacle of evolution? Are they? Explain.
Answers
Answer:
Yes, humans are the pinnacle of evolution.
Explanation:
Adaptability to the change environment by the human is the only reason for the survival of human beings as compared to other hominids. The human survival also occurs due to evolution that changes the physical structure of humans and they are able to survive in that environment condition in which no other hominids survives so we can say that humans are the pinnacle of evolution.

Scientists can learn all of the following by studying fossils EXCEPT:
Question 2 options:
How life forms have changed over time
How the environment has changed over time
How the surrounding rock layers have changed over time
How the Erath's surface has changed over time
Answers
Answer: How the surrounding rock layers have changed over time
Explanation:
I’m taking a minion quiz in science class and I submitted it and we’ll that’s the correct answer
The changes in surrounding rock layers over time cannot be studied by fossils. So the correct option is C.
What are the uses of fossils?We can learn a lot about the Earth's history of life thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.
Important evidence for evolutionary and the environmental adaptability of plants and animals may be found in fossils. Fossil evidence shows how organisms developed and how a "tree of life" may be used to illustrate this process, demonstrating the interconnectedness of all species.
Rocks can also be dated using fossils. Geologists may use fossils to study geological history because different types of fossils appear in rocks of various ages as a result of evolution. Fossils are one of the most crucial instruments for age correlation in geology.
Ammonites, for instance, are great reference fossils for stratigraphy because they may be used to compare the relative ages of two or more strata, or layers of rock, that are located in various locations across the same nation or elsewhere in the world.
Therefore, the correct option is C.
