Answer:
plant growth rate will remain the same
Explanation:
Photosynthesis is the process by which green plants generate carbohydrates (sugars) and oxygen from carbon dioxide, water, and light energy.
The balanced equation is as follows: 6CO2 + 6H20 + (solar energy) → C6H12O6 + 6O2
Note that "all other factors affecting photosynthetic rates were equal, ONLY atmospheric CO2 concentration were the main factor affecting photo synthetic rates"; then time (400, 000years) and 30 degrees C in the daytime temperature of 30°c will mean nothing.
Plants' chlorophyll will only trap the solar energy required to combine 6 moles of CO2 to 6 moles of H2O. Hence,
Answer:
a. The corn borer must have or generate (by mutation) heritable variation in resistance to the toxic protein.
b. The resistant corn borers must survive better or reproduce more than nonresistant corn borers.
Explanation:
When there is a change in the surroundings of organisms, some genetic variations become beneficial to the organisms. Natural selection favors the organisms having these genetic variations.
The development of resistance in the corn borer population requires the presence of the gene for the resistance in the population. If there is no gene already present in the population, there should be a mutation to give rise to such gene/s. The corn borers having this gene should be able to survive better in the presence of the toxic protein and should leave more progeny in order to increase the frequency of the gene in the population over the generations.
Answer:
Part A: False
Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic
Explanation:
The Ames test, also known as <em>Salmonella typhimurium</em> reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).
Answer:
Qualitative data simply is the none numerical data which is simply obtained through observations and recording it. It talks about mainly quality. While quantitative data is the numerical data input. It talks about quantity, how much, how many and so on.
