- Calculate the average age of an Ovis dalli in the population occupying southern Montana in the 1850s using the data provided in TableWhat is the overall phenotypic frequency of tuskless elephants in the total elephant population of the table? Show your work.As a hypothetical example, imagine that you were studying a population of Eastern Collared-Lizards (Crotaphytus collaris). The lizards laid 2000 eggs, of which 1000 were eaten by raccoons and skunks. Eight hundred of the surviving juveniles were eaten by foxes and cats. One hundred and eighty of the young adults died during their first hibernation period. What is the indispensable mortality for each stage? If you want to increase the numbers of reproducing adults, which stage should you focus on?
- Imagine we census a population of rabbits (assume females only) that has been occupying a barn for a few decades. On June 30, 2021, we census the population right after the reproductive season. We count 650 individuals and divide them into 4 age classes: 0-‐6 months, 6 months-‐1 year, 1 year to 1-‐and-‐a-‐half-‐years, and 1-‐ and-‐a-‐half to 2 years. 350 are in the first age class, 175 are in the second, 90 are in the third, and 35 are in the fourth. We repeat the census at six months and find that none of the newborns (0-‐6 months age class) from the first census have produced any offspring, and that 15% of them have died. We find that the 2nd age class had 75% survival and produced 500 offspring. We also find that only 10% of the 3rd age class has survived, and produced 180 offspring. All the rabbits in the 4th age died and produced zero offspring. (a) What is the life table for this population?

- • select 15 animals that are endemic only to the Philippines. (native and restricted to a certain place) • describe the characteristics of these animals and create a dichotomous key for these animals. Picture below is only a sample.[itemB5] (refer to the photo below) Which has a longer life expectancy - fish or oysters?Seven sauropod dinosaurs of the same species (Apatosaurus ajax) from the same population in Montana have neck lengths of 7.3, 8.0, 7.7, 7.8, 8.3, 8.4, 7.9, and 8.0 meters. A different population of the same species from Utah has neck lengths of 8.0, 8.3, 8.3, 8.8, 8.1, 9.0, and 9.3 meters. a) Calculate the mean, median and mode for each population. b) If wanted to compare data from the two populations, what type of graph would you choose and why?
- Most species of seafood that are selected for aquaculture are herbivores. True False Farmed catfish are normally harvested at 6 months of age. True False In recent years, modern breeding methods in swine production have resulted in fewer breeds and a narrowing of the genetic base. True FalsePlease check if my answer is correct. Thank you. Assuming there is random mating, find the gene frequencies, genotypic frequencies, and the proportion of individuals with the different blood types (Type A, B, AB and O) if the population is composed of the following: Type A - 80 Type AB – 35 Type B - 90 Type O - 195In a population of 500 fruit flies, 250 are genotype RR, 100 are genotype Rr and 150 are genotype rr. Determine the allele frequencies for this gene in this population. Remember that the frequencies should add to 1. Please show your work.
