Answer:
To present visual information to the reader along with detailed descriptions of the visual sources which are presented.
Explanation:
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

The sperm plasma then fuses with the egg's plasma membrane, the sperm head disconnects from its flagellum and the egg travels down the Fallopian tube to reach the uterus. In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
Answer: C: The total mass of glucose and oxygen formed from photosynthesis is equal to the total mass of carbon dioxide and water used up during the reaction.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
