Color blindness is sex linked recessive. (Use the XX and XY with superscripts in your cross) A man who is colorblind marries a woman who is a carrier for colorblindness. What is the probability that they will have a daughter who is colorblind?
Answer:
50%
Explanation:
Using a Punnett Square, we can find the probability of colorblindness. cc x Cc would be a 50% chance of being colorblind, and a 50% chance of not

Does cellular respiration happen in the chloroplast?
The first hill on a roller coaster the largest one. The potential energy at the
top of the hill gives the roller coaster train enough energy to make it through
the ride and back into the station. Which law explains this situation?
A. Law of Inverse Square
B.Law of Gravity
C.Law of Conservation of Energy
D. Law of Conservation of Momentum
Answer:
B.Law of Gravity
Explanation:
The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero).
Roller coasters are ruled by the Law of Inertia. Since an object at rest, stays at rest, at the beginning of the ride a stationary roller coaster is at rest and will need to be pushed or pulled along to get it started. Most are pulled up a large hill called a lift hill.

12. What is the function of the vacuole? *
(1 Point)
A. sac that stores water, nutrients and waste products
B. sac filled with digestive chemicals
C. jelly-like substance within the plasma membrane
D. stack of membranes that package materials
The vacuoles are the structures found inside the cells that store water, nutrients as well as waste products. So the correct option is option A.
The vacuole plays a vital role in many cells. Mature cells of all land plants, most fungi, and algae (with the exception of prokaryotes) contain vacuoles. On the other hand, animal cells and immature plant cells (as well as some highly immature plant cells (stone cells) contain no vacuoles.
These vacuoles store the essential nutrients and water that a cell needs to survive. They also contain the waste of the cell and protect it from contamination.

Polydactyly is a trait found in cats and humans in which a person (or cat) has 6 digits per
hand or paw. The allele for polydactyly is rare but dominant. If a man who is heterozygous
for this trait marries a woman with 5 fingers, what are the chances that they will have a child
with polydactyly?
Answer:
1/2 or 50%
Explanation:
This question involves a single gene coding for the number of digits per paw in cats or humans. The allele for polydactyly i.e six digits (P) is dominant over the allele for normal number of digits i.e 5 (p).
According to this question, If a man who is heterozygous (Pp) for this trait marries a woman with 5 fingers (pp), the following gametes will be produced by each parent:
Pp : P and p
pp : p and p
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Pp, Pp, pp and pp
The offsprings with genotype Pp will have polydactyl, hence, the chances that they will have a child with polydactyly is 1/2 or 50%.

Nuclei with an _____________ number of protons and neutrons possess a property called spin. Nuclear spin can be thought as either up or down with the spin states normally possessing _________ energy levels while generating equal but opposite _________ When a molecule is placed in an NMR, a large ________ field is applied making the spin states become of unequal energy, with the spin that generates a magnetic field in the same direction of the applied magnetic field being ___________ in energy. The NMR then uses _________ to 'flip the spin' of each nuclei, wherein each nuclei will require a specific energy level of radiation that corresponds to its difference in energy of spin states, this is often called the nuclei's __________ frequency, which is measured by the NMR and translated to teh final spectra.

Scenario 1: A river in North Carolina has been tested and the following data is obtained:
pH = 7.1
Dissolved Oxygen = 7 mg/L
Nitrates = 8 mg/L
Phosphates = 0.03 mg/L
Biotic Index = 3.5
What is the overall quality of this river? How do you know? If the quality is low, what do you think could be happening in the environment to cause these readings?
Answer:
Good.
Explanation:
The overall quality of this river is good because all the levels is in normal range. Healthy water should have 6.5 to 8 mg/L of dissolved oxygen concentrations, normal range of phosphorus is 0.005 to 0.05 mg/L, levels of nitrate at or below 10 mg/L and the biotic index less than 3.75 is considered normal and the data shows all value of substances comes in normal range so we can say that the quality of water is good.
