Which sentence best describes the logic of scientific inquiry?
(A) If I generate a testable hypothesis, tests and observations will support it.
(B) If my prediction is correct, it will lead to a testable hypothesis.
(C) If my observations are accurate, they will support my hypothesis.
(D) If my hypothesis is correct, I can expect certain test results.
Evoution connection A typical prokaryotic cell has about
$3,000$ genes in its DNA, while a human cell has almost $21,000$
genes. About $1,000$ of these genes are present in both types of
cells. Based on your understanding of evolution, explain how such different organisms could have this same subset of $1,000$ genes. What sorts of functions might these shared genes have?

in this video, we will cover nature versus nurture. So this is a hotly contested debate that has been ah, growing for centuries on it relates to what is going to beam or important in terms of development of an individual. Will it be the nature or the environment, or will it be the, um, ingrained aspects of that person's genome? And in the case of nature versus nurture, of course, this applies also to behavior and psychology. But we see this in the context of the genome as nature being, what is going to be part of your genome or part of your genes and Leo's and the Gina type that you have versus the nurture aspect, which is gonna be the environments impact on the phenotype that you produce. Well, the answer is, that is a little bit of both. Nature is going to be dictating in a guideline or a framework for what kinds of FINA types you might, uh, display. But the nurture aspect is going to determine specifically what kinds off feta types you will display. So the nature provides the guidelines, the framework for the possibilities and then nurture is going to pick out which possibility is going to be the one display and also it's important to note that although you have this set Gina type that says, well, you are going to have, let's say if this is a plant, you're going to have a large leaves. But in reality, we find that leaves there going to be all of various different sizes. And this just shows us that although yes, maybe the overall average leave size of that plant might be large, they're still going to be small leaves there. And depending on what side of the plant we're looking at, we might see larger leaves or smaller leaves. So it all comes down to the actual positioning off that individual in the environment. So it's going to be a little bit of both. And as we said, the nature aspect is going to give us the framework or the tools that we have to work with in order to ah produce a specific phenotype, whereas the nurture will choose or select which phenotype to be expressed. So this range of FINA types that will occur due to the nature due to the Gina type that you have will be named the norm of reaction. So the norm of reaction is going to relate to the range of different fino types that may be expressed by a certain individuals Gina type. So this normal reaction will differ, and that specific range will differ based on what kind of trait we're looking at. So if we're looking at a B o blood group types, well, those are going to be pretty cut and dry. If we have an A ah, Leo present, then we're going to have a androgen present and that will be our phenotype. We will be type a blood. Alright, if we're going to have, um type B A Leal's, then we're going to have type B blood. It's like, uh, this very definitive equation and if we have these certain deals, we're going to produce that certain female type. But then when we look at other factors such as blood count of red and white blood cells, this is going to vary tremendously based on the environment. So this range is actually going to be ranged, so there's going to be arranged for the range so the certain things will have a very small range of error or variability and other things. Other fino types will have even extremely large range of variability, so the range of variability, or that normal reaction will vary depending on the feta type or treat in question. So, for example, there's going to be greater variability in our A red blood cell rather than in blood type. So to answer the question of which one will be most important, what the answer is both both are going to be needed both nature and nurture. Both are going to impact the phenotype, and together they are able to produce the individuals that we are. So this is going to be a multifactorial approach where there are multiple factors at play.
