On the planet Feline, there are only cats. For one particular phenotype, Myles, there are two manifestations: either the cats like jazz music (the wild type phenotype) or they do not (the mutant phenotype). Under the assumption this phenotype is determined by a single gene with two alleles, and given that a mating of two wild-type cats produces the following number of offspring: Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123. The mode of inheritance most consistent with these data is:________
A. Autosomal dominant.
B. Two-locus inheritance.
C. Sex-linked recessive.
D. Autosomal recessive.
E. Two-locus dominant.
Answer:
D. Autosomal recessive.
Explanation:
Available data:
One diallelic gene codes for the phenotype MylesOne allele expresses the wild type phenotype → like jazz musicThe other allele expresses the mutated phenotype → don´t like jazzCross: Between two wild catsF1) Female, wild-type: 341; Male, wild-type: 369; Female, Myles: 121; Male, Myles: 123Autosomal recessive inheritance characterizes because the mutated gene locates in one of the 22 non-sexual, somatic chromosomes. To express the phenotype, an individual must carry two copies of the mutated gene. For this reason, the recessive allele must be present in both the male/father and the female/mother.
In the exposed example, the numbers among the progeny are 341:369:121:123. These values approximate a phenotypic ratio 3:1 for females, and for males. This ratio suggests that the cross was performed between two heterozygous individuals.
Let us name the alleles M and m, dominant and recessive respectively. The cross would be like follows
Cross: wild-type male x wild-type female
Parentals) Mm XY x MmXX
Gametes) MX, MY, mX, mY MX, MX, mX, mX
Punnett Square) MX MX mX mX
MX MMXX MMXX MmXX MmXX
mX MmXX MmXX mmXX mmXX
MY MMXY MMXY MmXY MmXY
mY MmXY MmXY mmXY mmXY
F1) Whole progeny
12/16 = 3/4 = 75% Wild-type cats → MMXX + MmXX + MMXY + MmXY4/16 = 1/4 = 25% Mutated cats → mmXX + mmXYFemales
6/8 = 3/4 = 75% Wild-type cats → MMXX + MmXX 2/8 = 1/4 = 25% Mutated cats → mmXXMales
6/8 = 3/4 = 75% Wild-type cats → MMXY + MmXY2/8 = 1/4 = 25% Mutated cats → mmXY

The answer is A. It is expensive to produce and transport
Explanation:
A young woman was going on a walk through the woods when she felt a mosquito bite her. She has a history of large local reactions to mosquito bites in the past. The reactions have been so severe she has even been skin tested, but the test came out negative. After the most recent bite, she went back to the doctor complaining of swelling at the site, dizziness, headache, and nausea. Benadryl is able to help relieve some symptoms. The doctor decides to try a blood test (i.e. ELISA based test) instead to test for allergies.
Required:
a. What is an ELISA test and how is it done?
b. Which antibody would they be looking for specific in this case?
c. The doctors also ran an SDS-PAGE test using the patient's serum mixed with two different antigens: lane 1 - bee venom; lane 2 - mosquito venom. What do the results show regarding the patient’s allergies?

Explanation:
If u and y are two variables such that
du
= 4v - 3. and u = 5 when v = 2,
du/dv
find u in terms of v.
Answer:
5
Explanation:
The value of u is 5 in term of v by putting the value o v which is 2 in the formula that is du = 4v - 3. Putting the value of v = 2 we get, du = 4(2) - 3. --- du = 8 - 3. ---- du = 5. we are able to solve the question due to the presence of v value. If the v value is not present then we can't find the value of u in term of v. So we can conclude that the value of u in term of v is 5 if we put the value of v in the formula.
A student is planning an investigation of the effect of population size on an ecosystem. She plans to use a five-gallon fish tank with ten goldfish for her investigation. How should the student perform her investigation? A. She should limit the amount of food given and observe the results. B. She should add a predator fish to the tank and observe the results C. She should continue to add more goldfish to the tank and observe the results D. She should change the temperature of the water in the tank and observe the results.
Answer:
C
Explanation:
Because the student is observing the effects on the population, so it would make more sense to add more fish to the tanks to see how they would get effected.
A student is planning an investigation of the effect of population size on an ecosystem, so she should continue to add more goldfish to the tank and observe the results, as in Option C.
What is the population size of an ecosystem?In the student's investigation, the goal is to observe the effect of population size on an ecosystem using a fish tank with goldfish. The student has already decided to use a five-gallon fish tank with ten goldfish for the experiment, so by adding more goldfish to the tank, the student can observe the effect of population size on the ecosystem. As the population of goldfish increases, the competition for resources such as food, oxygen, and space will also increase. This can lead to changes in behavior.
Hence, she should continue to add more goldfish to the tank and observe the results, as in Option C.

Describe the different types of traits that exist.What factors can affect these traits?
Answer:
Cardinal traits, central traits, and secondary traits.
Explanation:
There are three types of traits according to the Gordon Allport which organized traits into three levels that is cardinal traits, central traits, and secondary traits. Factors that affect these traits are the environmental factors as well as genetic factors. Some of these traits acquire by an individual through inheritance while on the other hand, other traits can get by the people through the exposure to environment that leads to the presence of that traits.

A certain lake has a volume of about 480 m³. If the total population of freshwater shrimp in the lake is 600 million, what is the population density of the shrimp in that lake?
Answer:
1,250,000 shrimps per m³
Explanation:
Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;
Population density = population (N)/volume
According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;
Population density of the lake = population of shrimps ÷ volume of lake
Population density = 600,000,000 ÷ 480
Population density = 1,250,000 shrimps per m³

I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.

The thyroid gland produces a substance
containing iodine that helps regulate growth.
Goiter is an enlargement of the thyroid gland
caused by a lack of iodine in the diet. Goiter
is uncommon in coastal areas where people
eat seafood that contains a form of iodine.
It is more common inland, where people
eat food that has been grown in soil
lacking iodine.
Which phrase restates the cause of the
disease goiter, as given in the passage?
(1) eating too much fish
(2) eating too little of foods high in iodine
(3) exposure to a bacterium found in iodine
(4) fertilizing the soil with iodine
(5) inheriting a defective thyroid gene
Answer:
eating too little of foods high in iodine
Explanation:
Iodine deficiency lead to goiter that is why it is necessary to consume food rich in iodine like taking iodized salt or sea foods which prevent this. This lead to goiter because, your thyroid gland need iodine to repair tissues, produce thyroid hormones, aid metabolism and for proper growth,therefore deficiency of it will result in non of the following functions.

Chemical reactions of fossil fuels
Difference between biomass and fossil fuels
Comparing biomass with other renewable
energy sources
Making energy choices locally
Answer:
CH4 + 2O2 -----> CO2 + 2H2O.
Explanation:
CH4 + 2O2 -----> CO2 + 2H2O is the chemical reaction of burning of fossil fuels. The main difference between biomass and fossil fuels is that biomass is biological material which can be derived from living whereas Fossil fuel such as coal, oil and gas are derived from biological material. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass is renewable just like other renewable energy sources because both can be used again and again. The energy choices locally occurs according to the availability of energy resources in that locality.
