10. A woman with average height, and type A- blood, and a man with type B+ blood and achondroplastic dwarfism, have a daughter with type O- blood, average height and cystic fibrosis.

What are the genes found in the gamete the father produced that led to the child? Start with ABO, Rh, height, cystic fibrosis, and sex.

(Separate each gene by a comma, e.g. the gamete produced by a blue-eyed, hairless knuckled person would contain b, kn).

Answer:

11.A woman with average height, and type A- blood, and a man with type B+ blood and achondroplastic dwarfism, have a daughter with type O- blood, average height and cystic fibrosis.

What is the probability of the gamete the mother produced carrying the genes that led to the offspring?

Select one:

a. 1/32

b. 1/16

c. 1/8

d. 1/4

e. 0

A Photosynthesis and Cellular Respiration Lab was done: 10 algae beads were placed in cuvettes labeled LIGHT and DARK with a color indicator and then LIGHT was placed under a bright lamp and DARK was placed next to it but wrapped in tinfoil. The pH was taken per the color indicator and the Absorbance was also taken (every 5 minutes for 45 minutes).

It was calculated that the slope LIGHT is 0.1261 and the slope DARK is -0.1491. pH increased the fastest in the LIGHT all the way up to 9.0 after 45 minutes and the ph DARK began at 8.0 but then slowly decreased to 7.0 after 45 minutes

I believe that the negative number indicates CO2 rate increases in the dark but decreases in the light as seen by the positive number ---

The question asks---> 1. Look up current ocean pH values. How do the current values compare to those from previous years? ((my answer: 8.1 pH today and 8.2 pH previously (slightly basic with a 0.1 pH drop). This represents a 25% increase in acidity over the last 2 centuries.)). Next, consider what you have just learned about algae and how the chemistry of the indicator used in the experiments you just performed works. Hypothesize why oceans are at their current pH. How is the pH of the ocean changing and why? How might this affect the organisms that live in the ocean?

Imagine that you have the DNA sequences from the intron of a gene in three species called A, B, and C. Species A and B are most closely related, while C is more distantly related. The sequences of A and B differ by 18 base pairs, A and C differ by 26 base pairs, and B and C differ by 28 base pairs. Fossils show that species A and B diverged about 1.2 Mya, but there is no fossil evidence as to when the most recent common ancestor of all three species lived. Use the genetic data to estimate that date. What assumptions are you making to get this estimate?

A 55-year-old Cambodian man, who “has never seen a doctor”, was found to be mildly anemic at the time of establishing care with a community-based family medicine physician. His CBC showed: hemoglobin 11.8 g/dL, RBC 5.9 x106/µL, MCV 65 fL, MCH 20 pg, MCHC 29.3 g/dL, reticulocytes 176 x103/µL, WBC normal, platelets normal. The most likely diagnosis is:

Iron deficiency anemia

Sickle cell trait

Aplastic anemia

Thalassemia minor
