Answer:
10%
Explanation:
The parental crossings = Cd/Cd x cD /cD
The distance the genes C and D = 20 map units
Determine the percentage of cd / cd recombinants that will be formed
the distance shows that there is only 20% recombinant progeny
The recombinants are : CD/CD and cd/cd = 20%
i.e. each recombinant progeny = 20% / 2 = 10%
hence % of cd/cd recombinant = 10%

Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.
Answer:
The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.
Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.
Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.
It is observed that constipation is more common among people in the western countries who eat more meat and processed food than us. What could be the reason for this? What should be changed in their diet?
I already know this answer, just checking, it's cuz of roughage
Answer:
yes your answer is correct
Explanation:
Constipation happens when the colon absorbs too much water, this can occur if the muscles in the colon are contracting slowly or poorly, causing the stool to move too slowly and lose more water. As meat need much water to digest, so they leads to problem of constipation. Hence, they should eat sufficient amount of water to cure constipation.
Constipation is common among people in western countries who eat more meat and processed food because there is no enough roughage in their bodies which prevents constipation .Fruits and vegetables like like corn etc contains lot of roughage.

A degraded ecosystem is replaced with a different but productive ecosystem type, one that might even include some nonnative species. For example, a degraded forest might be replaced with a productive pasture.a. passive restoration b. remediation c. partial restoration d. rehabilitation e. complete restoration
Answer:
d. rehabilitation
Explanation:
Technology-associated rehabilitation is an ecological practice that allows a degraded area to be restored, rehabilitating all its degraded habitats. However, this restoration is not done naturally, but is caused by human intervention, which can cultivate the entire plant population in the area, even adding non-native species, which are selected to leave the productive area, but ecologically harmonious.

Contrast potential and kinetic energy. Give an example of potential being changed to kinetic energy.
Answer:
First, the raised hammer has more potential energy since it has the potential to go higher or lower. Second, when you hit the hammer on the table, the stored potential energy is converted to kinetic energy as the hammer is falling. (It's the falling hammer that has kinetic energy)
Explanation:
Another example-When rolling a ball down a ramp the ball at its highest point has potential energy but when it rolls down the ramp it converts to kinetic energy

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimilatory or dissimilatory manner?
a. low concentration or ammonia
b. low concentration of sulfate
c. oxygen present
d. low temperature
e. oxygen absent
f. high concentration of nitrite
Answer:
Dissimilatory- oxygen absent
Assimilatory- high concentration of nitrite
Explanation:
In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes
When blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. What does this process best exemplify
Answer:
homeostasis
Explanation:
Homeostasis has to do with processes that maintain the internal balance within an organism. It can succinctly be defined as the process of regulating an organism's internal environment. The process of homeostasis is very important in the maintenance of important indicators of balance in the body such as body temperature, body pH, etc.
Hence, when blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. This is a homeostatic response.

The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?
Answer:
The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).
Explanation:
Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.
In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.
In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..

A solid reactant is placed into a beaker of a warm water. The liquid vigorously bubbles as the solid dissolves into the solution. What will most likely happen if the temperature of the liquid is slightly reduced?
More bubbles will be produced because the solution is becoming more concentrated.
Fewer bubbles will be produced because of fewer collisions of reactant molecules.
The solid will get smaller at a faster rate because of more collisions of reactant molecules.
The solid will get larger at a slower rate because precipitate is coming out of the solution.
Answer: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
Answer:
B: Fewer bubbles will be produced because of fewer collisions of reactant molecules.

A population of snails is experiencing disruptive selection in terms of their shell patterns.
Which statement about the population is most likely true?
Two different shell patterns are combining into one very common pattern.
Snails with two different shell patterns are surviving in greater numbers than snails with the most common shell pattern.
Snails with a new shell pattern are surviving in greater numbers than snails with all other shell patterns.
Snails with the most common shell pattern are surviving in greater numbers than snails with all other shell patterns.
Answer:
Snails with the most common shell pattern are surviving in greater numbers than snails with all other shell patterns.
Explanation:
This is because of the natural selection process. The better adaption of the most common shell pattern makes it easier for the snails to survive the natural habitat.

Senario: 2 years ago, a fruit was smuggled into California on a plane from an exotic, far away land. The homeowner saw that the fruit had maggots and tossed it into the backyard, hoping the seed would grow. The larvae hatched out and moved throughout the area. This fictitious insect will destroy fruit and has the possibility of spreading disease killing the trees. The insect consumes plants in the Prunus species of stone fruits? Look up the plant genus Prunus.
Discussion: The insect has spread over a large area of Southern California, discovered at UC Riverside. What steps would you do to control or eradicate the destructive exotic insect?
Answer:
To destroy this insect, a chemical should be used or made that will fight the main power of the insect. Also the food that is targeted should be removed.

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer
Answer:
The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.
