I'm strong and stiff Getting through me is tough I'm found only in plants I'm what makes sticks tough Question 10 Answer the following questions concerning the given word problem. Suppose researcher is studying how fast a new disease is spreading. Initially the researcher has 2 mL of some disease. After 2 hours the researcher has 10 mL a. Find \( P(t)=A e^{r t} \), where P(t) is the amount of disease the researcher has in mL after thours. No decimals. b. Interpret \( ' \mathrm{r} \) " from part a. Round 3 decimals in the end. c. How much disease does the researcher have after half of a day? round 3 decimals d. How many days will it take for the researcher to have 2000 mL of the disease? Do not round until the end. Round 4 decimals. Use the editor to format your answer Which type of organism are generally_considered prokaryotic? Plant Animal Bacteria All of the Above The doubling period of a bacterial population is 15 minutes. At time \( t=100 \) minutes, the bacterial population was 50000 . What was the initial population at time \( t=0 \) ? 492 Find the size of the bacterial population after 4 hours. 32243712 What happens during the link reaction, the stage that links glycolysis to the Krebs cycle? \begin{tabular}{l} All of these \\ ATP is produced. \\ \( \begin{array}{c}\text { Acetyl-CoA (the starting compound for the } \\ \text { Krebs cycle) is produced. }\end{array} \) \\ Water is formed. \\ \( \begin{array}{c}\text { Glucose is split to form two molecules of } \\ \text { pyruvate. }\end{array} \) \\ \hline\end{tabular} . The doubling period of a bacterial population is 20 minutes. At time \( t=80 \) minutes, the bacterial population was 70000 . What was the initial population at time \( t=0 \) ? Find the size of the bacterial population after 3 hours. How do protons (hydrogen ions) move through ATP synthase? \begin{tabular}{|c|}\hline They are forced through by endocytosis. \\ \( \begin{array}{c}\text { They are pumped from low to high } \\ \text { concentration, using ATP energy. }\end{array} \) \\ \( \begin{array}{c}\text { They diffuse from high to low concentration } \\ \text { passively. }\end{array} \) \\ \( \begin{array}{c}\text { They are pumped from low to high } \\ \text { concentration, using electron energy. }\end{array} \) \\ \hline All of these. \end{tabular} Abiotic factors that could affect the stability, of an ecosystem could include A. hurricanes, packs of wolves, and temperature B. blizzards, heat waves, and swarms of grasshoppers C. droughts, floods, and heat waves D. species of fish, number of decomposers, and supply of algae Includes species with the mos intelligence of all invertebrate On considère un couple de lapins nouveaux-nés, un mâle et une femelle. Les lapins sont capables d se reproduire dès l'âge d'un mois et la gestion dure également un mois. Nous supposons que la femell donne à chaque fois naissance à un mâle et à une femelle.
