the first answer as blood needs to be oxygenated to be passes round the body then when its deoxgenated it will return to the heart to be pumped around the body again
They are similar a bit like this ----
It is true that the testicles are similar in shape to ovaries, but that is where those similarities end. Males do NOT start as females. All humans start out the same, asexual. When hormones are introduced during development, the s-xual organs form. If a female has too high of testosterone during development, they will be come a hermaphrodite and have what looks like both organs and same goes if males and they actually begin life as the same organ structurally anyway. That's why it's so difficult to tell the sex of a very young fetus they all have a phallus which becomes a pen-s in males and a cli-oris in females. The gonads are all internal at that time. They become ovaries in females and descend and become testicles in males.
Hey there,
Your question states: <span>Several genes interact, along with the environment, to determine a person's height. which inheritance pattern best explains how genes influence human height?
Your correct answer would be the "</span>polygenetic inheritance" because the way you are is the reason why you are. If your daddy is tall, the <span>polygenetic inheritance would make you tall. That's how it works. If your mom has a big head, you might have a big head, but It might be bigger, or it might even be smaller. So by how your family looks, you would look like them put together. So in a sense, you would be a tall boy/girl with a big head. I'm not saying that to offend anyone, that would just be an example.
