Answer: B
Explanation: I think the answer is B because natural selection leads to evolution because they happen in a line or like a chain reaction.

Answer:
In vitro fertilization (IVF)
Explanation:
In vitro fertilization is conducted when infertility is perceived in sexual partners trying to have a baby. It is the process whereby matured ova/eggs are removed from the female's reproductive system and is fertilized externally in a laboratory (usually in a glassware) using a male's sperm cell. It can be thought of as a procedure where the normal fertilization process that occurs in a female's reproductive tract (fallopian tube) is carried out outside the body, specifically in a laboratory.
In order for this procedure to be employed, the male and female must be able to produce their respective gametes. The female's ovary is usually stimulated by fertility drugs in order to yield numerous eggs, which are then extracted from her ovary and fertilized by a sperm externally (in a laboratory). The resulting fertilized egg called embryo is placed back into the female's womb to carry it as a normal pregnancy.
Answer:
Rate of photosynthesis will be increased
Explanation:
Photosynthesis is a process whereby plants manufacture their food (in form of carbohydrates) in the presence of sunlight. The photosynthetic process, which occurs in the chloroplast of plant cells, require carbon dioxide (CO2) as one of the reactants, from the atmosphere. The general photosynthetic equation is given below:
6CO2 + 6H2O → C6H12O6 + 6O2
Based on the above equation, it shows that carbon dioxide (CO2) as a reactant can either increase or decrease the rate at which photosynthesis in plants occur depending on whether it is increased or decreased in the atmosphere respectively.
According to this question, the concentration of carbon dioxide in the atmosphere has been increasing for many years. This means that the rate at which photosynthesis by plants occur will also be INCREASED.
Answer:
adding a catalyst
