It connected cities to various water routes
Answer:germinal, embryonic, and fetal
Explanation:
Germinal Stage this is the conception stage when the egg get fertilised by the sperm which occurs in women's fallopian tubes. When the egg is fertilised it is then referred to as a zygote. A zygote will then travel to the uterus which may take a week to get there. In the uterus it's where the single felled zygote will start to multiply cells and grow. It start and last from 0 - 2 weeks.
Embryonic Stage
The multiple cells are known as the embryo. This begins at the third week in which the multiple cells start to actual form something that can now be referred to as a human and not just cells. This is the crucial stage for brain development.
This is where the signal cord also develops.
Fetal stage
When cells have actual be distinct such that it can be visible that this is a human , the embryo now will move to the next stage in which it becomes a fetus. This occurs at the ninth week and until the baby is born.
The development of body system and structure continues and get more established than it was in embroynic stage.

Answer:
variables that help to increased the rate of diffusion are
1) concentration of glucose
2) by increasing the number of membrane carriers
Explanation:
variables that help to increased the rate of diffusion are
1) concentration of glucose - the rate of diffusion increased when molecules concentration outside the cell is more than internal concentration. It is all part of the concentration gradient. Higher the concentration gradient higher will be the rate of diffusion
2) by increasing the number of membrane carriers - the rate of diffusion increased by increasing concentration of solute in the cell which is increase by carrier proteins.
