At the moment humans can be at different trophic levels depending on what they eat. A vegetarian is at the second trophic level as s/he eats only plants. Someone who ate only grazing animals would be at the third level. If you eat a carnivore such as a tuna fish you are at the fourth level. Most of us eat both plants and animals so we don't really have a level. That said, if we all moved to a specific diet there would probably be gradual genetic changes to favour our coping with that. We see some evidence of this in isolated groups with restricted diets today.
Conception occurs when a sperm cell from a male fertilizes an egg cell from a female, forming a zygote. This usually happens through sexual intercourse, where the sperm is released into the female's reproductive tract and travels to meet the egg in the fallopian tube. Once fertilization occurs, the zygote begins to divide and eventually implants in the uterus to develop into a fetus.
pH is important to the body because thousands, perhaps millions of chemical reactions occur within the body. For you to LIVE, all these reactions must go fairly successfully. For this to happen, certain variables have to be satisfied. Such examples include pH, temperature, etc. So, if the pH is too high or too low, these necessary reactions may not occur as they should. Thankfully, our bodies have evolved over time so that we can usually have a wide range for the variables to be in.
If the population of one organism increased, it could lead to competition for resources among species at lower trophic levels, causing potential shifts in the food chain dynamics. This could result in either an increase or decrease in the populations of other organisms in the food chain, depending on the specific interactions and relationships within the ecosystem.
When your feet fall asleep, it is usually due to pressure on nerves or restricted blood flow, which can happen when sitting or lying in a certain position for a long time. This can temporarily disrupt the nerve signals and cause the tingling or numbness sensation in your feet. Changing positions or moving around can help alleviate this feeling.
If a gene encoding a protein is altered at the DNA level, it can result in a change in the protein's amino acid sequence. This alteration can lead to changes in the protein's structure and function, potentially affecting its ability to interact with other molecules and carry out its normal physiological roles.
Biologically it can happen, but in most places this is considered one of the vilest acts.
Because biologically, that's the whole point of sex - that's what sex evolved for.

Pole Position II happened in 7800.
They havent really changed because nothing has happen to them.
in order for reactants to be changed into products, there needs to be a chemical change.
Pole Position - video game - happened in 2600.
If you were to kill all the organisms in one trophic level, it would disrupt the entire food chain. This disruption would affect the populations of organisms in other trophic levels, ultimately leading to ecosystem imbalance and potential collapse. Each trophic level plays a specific role in maintaining the balance and stability of an ecosystem.
The world changed after Adolf Hitler whipped the Germans and Japanese into a fighting frenzy, after that the United Nations made an agreement to act apon any Genocide that may happen from then on. This was to stop another man like Adolf Hitler from gaining a position of power ever again.
A business in the defense position is defending its position within its industry. This can happen as a result of new entrants in the industry.
The mean is changed.
This is a sign of illness.
