1. What percentage of puppies would have the same genotype as the
parents, Ww?
Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.
The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are designated male. Individuals with XO (only one X chromosome) are designated female. Identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the offspring. An XY parent with a round nose and a XX parent with a round nose have an offspring with Klinefelter Syndrome (genotype XXY) with a pointed nose.
Answer:
Explanation:
in this case female parent XX is hetrozygous for round nose. when a cross between round nose father XY and hetrozygous round nose mother takes place and suddenly a chromosomal nondisjuction occurs, the chromosomes carrying genes for pointed tip nose come togather in a gamete and a gamete (egg) with XX chromosomes is appeared having 24 chromosomes instead of 23. when this gamete fertilizes with a sperm having normal 23 chromosomes and only carry Y chromosomes, a pointed nose klienfelter syndrome case will appear.

A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

List 7 facts about a meteoroid
Answer:
https://solarsystem.nasa.gov/asteroids-comets-and-meteors/meteors-and-meteorites/overview/?page=0&per_page=40&order=id+asc&search=&condition_1=meteor_shower%3Abody_type
Explanation:
Answer:A meteoroid is a chunk of space rock. If it burns up while entering the Earth’s atmosphere it’s called a meteor and if a piece lands, it’s called a meteorite.
Millions of meteoroids travel through the Earth’s atmosphere every day, but most are small and burned up quickly. Very few reach the ground.
When a meteoroid hits the atmosphere of the Earth, they can be travelling as fast as 130,000 mph (209,215 km).
The blast caused by the shockwaves of the Chelyabinsk meteor in Russia was picked up by infrasound sensors on the other side of the world. Below is a video of that meteor.
The buying and selling of meteorite pieces in South Africa is illegal.
A meteorite that is seen or detected as it lands are called “falls”, with those that are discovered later being referred to as “finds”.
Meteoroids more than 10 metres in diameter are classified as asteroids.
Of the 500 estimated meteorites that reach the ground every year, only five or six are recovered for scientists to study.

Eutrophication both hurts and helps
aquatic environments.
true
false
Answer:
False. Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.
If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
a) true
b) false
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".

Explain how you found out that Lucy has ADA-SCID
Answer:
The first part of finding out Lucy having ADA-SCID was when I realized there were no HIV proteins in her blood, getting rid of the possibility of her having HIV. Then, I realized she had a high number of Deoxyadenosine in her blood. This proves she has ADA-SCID because when the ADA doesn't work you find excess amounts of Deoxyadenosine in the blood.

Explain how seasons are similar and different on your Uranus as compared to the Earth.
Answer:
Uranus, like Earth, has four seasons. ... For starters, the length of Uranus' seasons are different from ours. It takes Earth 365 days to orbit around the sun, but it takes Uranus 84 Earth-years, more or less. So Uranus' year is 84 Earth-years along, and each season on Uranus lasts 21 earthly years.
