D. it does not become more difficult for the cell to get enough oxygen and nutrients.
So, as you know, when a sperm cells (Male sex cell) meets the Egg cell (Female Sex Cell) it forms something called a zygote. And from that point on, the egg cell reproduces more and more (making more cells) in a type of cell called a stem cell, which can be used for anything the body needs. The newborn babies keep these cells up until birth or the incubation (growth of the baby in the mother's uterus), and then they are ready to be born.
Answer:
b)eutrophication
Explanation:
have you ever seen a lake or body of water with a layer of green on top? That's eutrophication due to heavy amounts of growth nutrients (primarily from runoffs from agriculture) in water. Simple plants utilize those and grow very fast. As they grow, they take up the oxygen and make water oxygen poor. These produce deadzones cuz the water life basically suffocates to death due to less oxygen. Eventually plants will also die
Answer: Dominant
Explanation: If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous. Determine if the chart shows an autosomal or sex-linked (usually X-linked) trait.
Experimenting. Experimenting is used in all three main branches of science, physics, chemistry, and biology, and is used in all the sub-branches of science, like marine biology, to make discoveries. Without experimenting, all we know about science would be random guesses.
