Answer:
they would probably go extinct
Explanation:
All what the word tetravalent means is that carbon can form 4 chemical bonds, due to the fact that carbon has 4 unpaired valence electrons in its furthest shell, which can be used to bond to other atoms, to form linear and cyclic structures in organic compounds.
Tetravalent also tells us indirectly what the molecular geometry of the atom would be if bonded to those number of bonds, if 4, then it would be tetrahedral and have bond angles of 109.5.
The DNA molecules will have 450 thymines if a DNA molecule has a total of 1500nucleotides
A DNA molecule also known as deoxyribonucleic acid is made up of a double helix.
The DNA molecule with a total of 1500 nucleotides will contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
This shows that the DNA molecules will have 450 thymines

Answer:
The circulatory system interacts with every organ and system in the body hence, it is vital for every organ and system to function properly.
The circulatory system carries oxygen to the lungs and takes the waste materials out of it. Hence, a malfunction in the circulatory system can cause the respiratory system to not work properly. Severe damages will be caused to the body if oxygen is not taken to and from the lungs.
The circulatory system is also involved in carrying waste materials to the kidneys. It helps carry the waste materials out of our bodies. Malfunctioning of the circulatory system can cause no excretion of wastes from the body which will eventually lead to the death of the organism.
Yes it moves up , because when going down a high speed on a roller coaster you’re body moves up and so does you’re stomach
