Topic: What does an ecologist do?

To reiterate what many have said... Ecology is the study of biotic (all the organisms (plants, animals, bacteria, etc) and their counterparts) and abiotic (non-living, such as the wind, wate, climate, cycles, etc) factors in an environment/ecosystem. But as Rihan says, it is a complex word and while...

The patient, in medicine, is always L-R when looking at them, so that is important to remember. It may be your left, but you say the patient's right side. If, in another meaning of observation, you tell by the position or directionality of the Aorta, Venae cavae, etc. Normally, the heart will be fac...

Jon, I love that you actually commented on that; i think it is one of the biggest misconceptions about viruses - that they are affected by antibiotics. But that seems to stem from a misunderstanding about what actually an antibiotic is. But nevertheless... I heard recently that some scientists devel...

Topic: What is food expiry date?

It, as once explained to me by in simplest terms by a professor, is the date at which it would take bacteria, fungi, etc to defile the product, which leads to expiration. For instance, canned food lasts longer because of the intense nature of the method - anaerobic bacteria, however, can negate this...

I disagree with such a coercion/persuasion, but it was effective and potentially saved either her baby's or her life. I am fine with doctors manipulating or other minor lies, and according to some this is minor, but it'd be wrong IMHO even if a religious person, of the same faith, said it to the sam...

Given the recent necro of the topic, and I haven't touched it yet, I'd like to add on. I think there are multiple reasons for homosexuality. It can include genetic, environmental, psychological, and social, though the last three tend to go hand in hand more often than not, in my opinion. I do not th...

I have no problem with what you said, Ski. In fact, I feel that way a lot of the time. And to keep this short, the M-Theory is what is believed to caused not just one big bang, but many. That said, what developed these dimensions for the M-Theory? It''s continuously coming to the same question. &quo...

In basic biology, you are taught what constitutes life. DNA would be organic matter and a biotic factor, but it is not alive... Even if you try to bring up any abiogenesis/biopoesis theory. DNA is simply a material used by living organisms. Viruses, also, if you remember, are not alive. That's reall...

No one said anything about a goal, lol. The only remotely related thing was when I said "toward something", as in something actually being different. But in no way implied a goal.

And you reiterated what I said. I don't know if that was your intent or not.

Natural selection takes place regardless of human interaction. But humans can manipulate it to a degree that maldaptations are irrelevant, depending on which one it is. For instance, if your eyesight is incredibly poor, we can stick glasses on you to help ensure survival. But it does occur, just in ...

1) Yes. 2) There are treatments, but it's like the flu causing viruses. They mutate and we cannot control them. As for the flue viruses, we cannot predict what it will be next season. For HIV, we cannot predict how it will mutate. This is why treatment usually includes multiple medications into a co...
