Answer:
a) The question "Do pumpkins grow bigger when fed milk?" it is already a hypothesis, which means that to apply the scientific method, we should establish an experiment, where we would select a squash squash, feed some with milk and some without milk and wait a certain period of time. After that time, we could move on to the stage of the scientific method called "evaluation of results" where we would evaluate the differences in development and size between the pumpkins that were fed with milk and those that were not. After that we would go to the phase called "conclusion" where based on the comparison of the results we would answer the hypothesis shown above.
b) A scientific question could be "Can bean seeds germinate in sterile soil?"
Explanation:
Scientific method is a set of steps that must be followed when someone wants to prove a hypothesis based on experimental and scientific data. These steps are: visualization of something questionable, formulation of the hypothesis about it, establishment of a scientific experiment to test the hypothesis, evaluation of the results of the experiment and conclusion.
A scientific question is every question that you can perform a scientific experiment to answer it. This scientific experiment is carried out with the steps of the scientific method.
Answer:
FfPp
Explanation:
If we take the two traits to be separate alleles, we can make flowers F (F is dominant; f is recessive) and pollen as P (P is dominant; p is recessive). So a pea plant with white flowers (recessive) and long pollen (dominant) will have the genotype ffPp or ffPP (because one dominant allele will express a dominant phenotype).
For this question, we will assume that the wild type (red flowers and long pollen) is homozygous, meaning it contains two dominant alleles.
If the wild type (FFPP) is crossed with the plant with white flowers and short pollen (ffpp), we can make a table illustrating the crosses. However, because there is only one possible gamete that each parent can form (FP and fp), we can assume that the F1 progeny will have identical genotypes, which can be expressed as FfPp (because combining the gamete from the wild type and the other parent can only give one phenotype).
Answer:
At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.
Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
