17. You bring a sample of flies from a natural population into the laboratory and begin selecting for high body weight by using the heaviest 20% of the population as parents each generation for five generations. If mean body weight remains the same in each generation
a) phenotypic variation is due only to effects of the environment b) phenotypic variation is due only to genetic variation among individuals c) VG > 0 d) VE = 0
18. Given the observations described in the previous question you would conclude that for body weight
a) heritability is zero b) heritability is greater than zero but less than 1 c) heritability is 1 d) heritability is greater than 1
19. The heritability of body weight in cows a) can be measured on a single individual b) is the proportion of VG which is due to VE c) is the proportion of VP which is due to VG d) is the proportion of VE transmitted to offspring e) all of the above.
20. When we say that the heritability of a trait in a particular population is zero a) the trait is not affected by genes b) the trait is not affected by the environment c) all individuals are genetically identical for genes affecting the trait d) individuals differ in genotype for the genes affecting the trait.
21. In the Hardy-Weinberg equilibrium formula (p2 + 2pq + q2), p2 and q2 are
a) genotype frequencies b) fitnesses c) allele frequencies d) numbers of individuals.
22. The reproductive fitness of an individual is determined mainly by
a) strength b) life span c) number of offspring d) owning a BMW
23. In a population with 980 AA, 840 Aa, and 180 aa individuals the genotype frequency of Aa individuals is a) 0.49 b) 0.98 c) 0.42 d) 0.81 e) 0.18
24. The frequency of the A allele in the population above is a) 0.49 b) 0.5 c) 0.6 d) 0.7.

As the Covid-19 pandemic continues around the globe, one area of active research is to identify a plausible origin of this novel coronavirus (also called SARS-CoV-2). Early genomic studies suggest that the evolutionary precursor to SARS-CoV-2 may reside in bats since the bat coronavirus and SARS-CoV-2 have many similar sequences. However, there have been no documented cases of direct bat-human transmission, which suggests that an intermediate host was likely involved between bats and humans.
There are many different species of bats, and the Chinese horseshoe bat is just one that may be linked to the Covid-19 pandemic. However, much research is still needed to support or disprove this hypothesis.
The diploid number for a horseshoe bat is 62 (i.e., 2n = 62).
Give the number of each of the following that would be present in a cell in a horseshoe bat during each of the following stages of either mitosis or meiosis.
A. Anaphase of mitosis:
I) chromosomes:
ii) chromatids:
iii) DNA molecules:
iv) telomeres:
B. Anaphase of meiosis I
I) chromosomes:
ii) chromatids:
iii) DNA molecules:
iv) telomeres:
C. Anaphase of meiosis II
I) chromosomes:
ii) chromatids:
iii) DNA molecules:

Your friend, Mona, sent you a paragraph below about Keto diet that she wrote. She knows that you are learning a lot about keto diet in Nutr 1100. Find 3 mistakes in the paragraph and replace them with the correct sentences.
"For meat lover, keto diet is for you. The keto diet is just about eating unlimited amounts of bacon, pork chop, and cheese. Keto also known as the ketogenic diet. It is a way of eating that allows the dieter to enter a state of ketoacidosis - your body is breaking down stored protein into molecules called ketones that are released into your bloodstream and flushed out in your urine. In order to get into this metabolic state, the diet consists of high-protein and very low fat foods. Studies have now shown that the diet can have benefits for a wide variety of different health conditions: hair loss and epilepsy."

what is the biological basis behind photosynthetic rate being influenced by the mass of the sprig? in other words one of the key problems you have is that if you have a bigger or a smaller sprig that weighs a different amount its capacity for photosynthesis will be based upon the sprig, why is that?
maybe this paper will help find the answer?

Superoxide dismutase is a very unique protein. It is the only protein that can catalyze faster than the rate of diffusion, which is usually a limiting rate for proteins since you cannot catalyze something faster than the amount of time it takes for your substrate to arrive at the active site. However, superoxide dismutase is able to do this. If you look at a diagram of superoxide dismutase, you will find a large cluster of basic amino acids surrounding the active site where the substrate binds. First, state the purpose of superoxide dismutase and what its substrate is. Then discuss how you think superoxide dismutase is able to have a kcat/Km that is faster than the diffusion limit.
