Answer:
Hydrophobic molecules in water often cluster together, forming micelles. Hydrophobic is often used interchangeably with lipophilic, "fat-loving". However, the two terms are not synonymous. While hydrophobic substances are usually lipophilic, there are exceptions, such as the silicones and fluorocarbons.

8. A scoop of ammonium nitrate is added to a beaker of water. Which is a quantitative observation of the experiment?
A. The ammonium nitrate dissolved in the water.
B. The temperature of the water decreased by 5°C.
C. A chemical reaction occurred.
D. The solution did not change color.
The correct answer is B. The temperature of the water decreased by 5°C
Explanation:
Temperature and the changes in it are part of quantitative observations because these can only be measured and understood through numbers. Indeed, the temperature is globally measured through different numerical scales such as the Celsius or the Kelvin scale. This does not occur in other qualities such as color because this is considered and analyzing using qualities or traits rather than values. According to this, the correct answer is "The temperature of the water decreased by 5°C."

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.
Suppose that 16 pairs of pintaloosa horses have one offspring per pair. How many of each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes for offspring expected to live past one week of age.
Number of:
Solid:____
Fewspot:_____
White Overo:______
Answer: Solid: 1 out 16;
Fewspot: 3 out 16;
White Overo: 0
Explanation: A pintaloosa horse is a horse which has genotype LplpOvov, i.e., it is heterozygous for overo and leopard.
Using a Punnett's square, a pair of pintaloosas can produce the following possibilities of offsprings:
Overo genotypeOv ov
Ov OvOv Ovov
ov Ovov ovov
Leopard genotypeLp lp
Lp LpLp Lplp
lp Lplp lplp
The expected phenotype for:
Solid is related to the Overo gene and its genotype is ovov, so from the Punnett's square, the possibility for a offspring is 1 out of 16;Fewspot is related to both Overo and Leopard gene. A fewspot horse is both Ovov and LpLp, so the number is 3 out of 16;White Overo is related to the Overo gene and these offspring dies at birth. Since it is asking for the number of ofspring to live past one week of age, there will 0 white overos;The number of solid overo is 2, fewspot is 3 and white Overo is 0
The question above is incomplete. The complete question is given below:
In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov.
The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots.
A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.
Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age. overo: white overo: fewspot:
The solution is given below:
It is very clear from the complete question that the number of:
Solid is 2
Fewspot is 3
White Overo is 0
What is a pintaloosa?
A pintaloosa is a type of horse which is produced from the breeding between overo and leopard.
So from the parameters given in the question, 2 different individuals possess genotype for overo (Ovov) phenotype.
This goes to say that just only out of the 16 pair will have an overo phenotype.

how is hair grown? give me a really really really detailed answer
Hair grows out of little pockets in your skin, called follicles. Here's how it happens:
Your hair begins growing from a root in the bottom of the follicle. The root is made up of cells of protein.
Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow.
The hair gets pushed up through the skin as it grows, passing an oil gland along the way. The oil gland adds oil to the hair and keeps it shiny and soft. It can make it greasy, too. That's why you need to wash your hair.
The hair dies by the time it is long enough to poke out through the skin. Yes, hair is dead. That's why it doesn't hurt to get a haircut.
Hair on the rest of your body goes through this same process, but the whole cycle only lasts for a month or so. That's why body hair does not grow very long in length like the hair on your head does.
Here are some facts about follicles and your hair:
You are born with all of the follicles you will ever have — about 5 million.
You have about 100,000 follicles on your scalp, which is the skin on your head.
Hair grows very fast and male hair grows faster than female hair. The only part of your body that grows faster is bone marrow, the soft stuff inside your bones. The hair on your head grows about 6 inches a year. So, even though it's one of the fastest-growing things on your body, it takes a while to grow it really long.
Some follicles stop growing hair as you get older. This happens more in some people than in others. That's why some people get thinner hair when they get older, or go bald.
Why does the oceanic crust sink beneath the continental crust at a subduction boundary?
A)The oceanic crust has a greater density.
B)The oceanic crust is pulled downward by Earth's magnetic field.
C)The continental crust is composed of more magnesium and iron.
D)The continental crust is pulled upward by the Moon's gravity.
The oceanic crust sink beneath the continental crust at a subduction boundary as it is pulled downward by Earth's magnetic field. The correct option is B.
What is oceanic crust?The outermost layer of the Earth's lithosphere found beneath the oceans and formed at spreading centers on oceanic ridges that occur at divergent plate boundaries.
The thickness of the oceanic crust is approximately 6 km (4 miles). It is made up of several layers, not including the sediment on top.
The oceanic crust is mostly made up of dark-colored rocks called basalt and gabbro. It is thinner and denser than the continental crust, which is composed of light-colored rocks known as andesite and granite.
Because of its low density, continental crust "floats" high atop the viscous mantle, forming dry land.
As the Earth's magnetic field pulls downward, the oceanic crust sinks beneath the continental crust at a subduction boundary.
Thus, the correct option is B.

Which best describes the advantages of food processing? control of density-independent limiting factors such as disease spread control of density-dependent limiting factors such as disease spread control of density-dependent limiting factors such as predation control of density-independent limiting factors such as predation
The statement that best described the advantage of food processing is that it controls density-dependent limiting factors such as the spread of diseases.
Processing foods through the addition of chemicals have the ability to kill off pathogens in foods, thus making the foods safer for consumption. The consumption of pathogen-free foods means that pathogenic diseases will be reduced to a minimum in a population.
The spread of diseases is a density-dependent limiting factor of a population. Density-dependent limiting factors have either positive or negative correlations with population growth. Other density-dependent limiting factors include competition and predation.

Digestive problems can occur at nearly any point in the digestive process. Some problems are minor, like occasional heartburn, indigestion, or constipation. However, other problems like ulcers or cancer can be very serious. Medical treatment may also be required if a minor problem occurs persistently. Fortunately, there are also many dietary approaches that can help manage many digestive disorders. One condition that can be managed through diet is celiac disease, a serious autoimmune disease that causes damage to the small intestines when gluten is consumed. Select all the sentences below that correctly describe the proper identification and treatment of celiac disease.
a. People with celiac disease should include foods with dietary fiber such as beans, fruits, vegetables, brown rice, and quinoa.
b. In adults diagnosed with celiac disease, full recovery typically occurs within 3 to 6 months.
c. For people with celiac disease, ingesting small amounts of gluten is okay occasionally as long as doing so does not produce severe symptoms.
d. If a person feels better after trying a gluten-free diet, further testing is not necessary.
e. Home-cooked meals are a good way to increase variety and reduce the cost of a gluten-free diet.
Answer:
a. People with celiac disease should include foods with dietary fiber such as beans, fruits, vegetables, brown rice, and quinoa.
e. Home-cooked meals are a good way to increase variety and reduce the cost of a gluten-free diet.
Explanation:
Celiac disease is an autoimmune disease, as stated above. This disease causes the defense cells of an organism to attack the stomach cells causing an inflammation that is extended and stimulated by the glutem. As a result, the individual has diarrhea, constipation, weight loss, anemia, a feeling of fullness, colic, abdominal discomfort, severe pain and may even develop ulcers and cancers.
Glutem is a protein found in wheat, barley and rye and for that reason, individuals with this disease should avoid these foods or foods derived from them. This type of diet should accompany the sick person for life and they should be encouraged to eat homemade foods that know the origin and composition. In addition, it is necessary that these people feed on dietary fibers, such as beans, fruits, vegetables, brown rice and quinoa.
