Question
Chapter 24.1, Problem 2R
Summary Introduction
To explain:
Mark boundaries between the sites given in Figure, which were formed, during the same geological time period.
Given:
Table 1 given below shows the ratio between the 206Pb and 238U and the estimated age of the sites given.
Introduction:
The ratio of 206Pb to 238U is known as uranium and lead dating. It is a radioactive dating technique used in earlier times to date the rocks that are formed in between 1 million years to 4.5 billion years ago. The number of radioactive isotopes of uranium and amount of other materials into which the radioactive isotopes would be decompose.

- when we collect fish or mussels we record a variety of biological information, including but not limited their sex, length, weight or a scale or finray or other tissue sample. Why do we do this, and what information are we hoping to obtain from these measurements and taking these samples?arrow_forwardDraw a rough sketch of the control and experimental data using a normal dose/response curve plot: i.e. % of total bound ligand vs. concentration. Indicate Kd and Bmax on this sketch. You don’t need to use exact numbers, but the relative proportions should be closearrow_forwardName something that could be happening to glutamate transporters that could have this effect on glutamate transport (i.e. the difference in glutamate transporters between control and experimental conditions).

- a. For the control condition, calculate Kd. Include units and show your work. b. For the control condition, calculate Bmax. Include units and show your work. c. For the experimental condition, calculate Kd. Include units and show your work. For the experimental condition, calculate Bmax. Include units and show your work.arrow_forwardNow draw a rough sketch of what the control data might look like if in addition to the specific binding, there was also a considerable amount of nonspecific binding (again using a normal dose/response curve)arrow_forwarda.

- The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?arrow_forwardNonearrow_forwardQuestion #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…arrow_forward
