Answer:
Chorionic villus sampling
Explanation:
Chorion is one of the extraembryonic membranes that surround the fetus and the amniotic cavity. The cells present in the chorion have the same genome and chromosomes as present in the fetus. Therefore, some of the chorionic tissues are collected from the chorionic villi. These tissues are then analyzed for any chromosomal abnormality. This process is called chorionic vill sampling. For the purpose, tissue collection can be done by inserting a catheter through the cervix or using a needle through the uterine wall.
Carbon emissions are lowering and waters are clearing
Answer:
Water obeys the Law of Conservation of Matter despite changing into different forms because when water does change forms, the amount of water stays the same. The Law of Conservation of Matter states that before matter undergoes change, be it through physical or chemical means, the same amount of matter exists. Matter cannot be created nor destroyed during the change. When water changes from a liquid to a gas the molecules change form by breaking the bonds that held them in a liquid state, but this does not create new matter. The molecules can now move more freely but are still the same as they were before. Same goes with the change from a liquid to a solid. The molecules slow down and become more compact, forming a solid. Though again, this does not create new matter nor destroy existing matter, therefore obeying the Law of Conservation of Matter.
