Answer:
The kinetic energy is transferred from the ball to the bumper. The bumper gives the same energy back and the ball eventually stops due to friction of the ground.
Explanation:
Hope this helps y'all <3
When a ball bounces off of a bumper and slowly comes to a halt. The transfer of energy takes place from the ball to the bumper and the ball keeps on bouncing until all the energy is transferred.
What is Energy transfer?Energy transfer takes place when two objects comes in contact due to collision or bouncing. The energy from the moving body is transferred to the body in rest.
In the given situation, elastic potential energy is causing the ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.
When a ball is dropped, the gravity pulls ball towards the ground, which slows the ball down so with each bounce the height becomes shorter and shorter, until eventually the ball stops bouncing. On the other hand, the force of the ball hitting the ground puts an equal force back onto the ball which bounces the ball back up.

An individual with Huntington disease has two normal parents. What are plausible explanations for this pattern of inheritance? Check all that apply. Check All That Apply A spontaneous mutation occurred in the mother's germline to produce a mutant HD allele. A spontaneous mutation occurred in the mother's germline to produce a mutant HD allele. A spontaneous mutation occurred in the father's germline to produce a mutant HD allele. A spontaneous mutation occurred in the father's germline to produce a mutant HD allele. A spontaneous mutation occurred in the individual's germline to produce a mutant HD allele. A spontaneous mutation occurred in the individual's germline to produce a mutant HD allele. Huntington disease shows incomplete penetrance.
Answer and Explanation:
The Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.
The Huntington disease characterizes for being,
Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene. Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy. Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.There are just a few cases all around the world (3% approximately) in which the disease is expressed with no family history. The progenitors are not affected by the mutation. These cases are very rare and are called "de-novo" mutations. A new mutation is spontaneously produced and it is not inherited from any of the parentals. It consists of an increase in the number of CAG repetitions. In a normal person, the number of CAG repetitions is less than 35. When there are 40 or more repetitions it occurs the disease. But when there are between 35 and 39 repetitions, the penetrance of the disease is incomplete. This is a "gray zone". Those alleles that fall in the gray zone are unstable and might produce the HD. Individuals with these unstable alleles have a tendency to increase the number of repetitions from generation to generation until the number reaches 40 repetitions and the person expresses the disease. This usually occurs in the paternal germinal line, as it is particularly unstable in sperm and probably meiosis greatly affects their instability, causing an increase in the number of CAG repeats.

One adaption to life in flowing water is what?
Answer:
Explanation:
There are many options, here are a few choices:
Fast moving water tends to be colder than slow water; some of it originates as snow melt on the sides of mountains, for example. For this, animals in fast water tend to be more cold resistant. This is why you do not see fish like freshwater trout in equatorial regions. These animals struggle and die in slow, warm water.
Fast moving water means that if the animal or plant wants to stay put, it must resist the flow. Fish tend to be far more muscular and lean in these places, while insects like stoneflies, mayflies, and other larvae have ways to secure themselves to rocks and plants while growing. Plants develop strong root systems, and algae hold fast in rocky crevices in the river. Some animals also have suction in order to stay in place where there is fast flowing water.
Some animals have to adapt their reproductive systems as well. Because finding a mate is difficult in the sweeping waters, breeding tends to happen all at one time. As an example, salmon have runs, where thousands of fish all swim upriver at once to breed, can dramatically alter the surrounding ecology of the river. Insects like mayflies have hatches, where hundreds of thousands of flies swarm into the air at once to breed and lay eggs.

Sickle cell anemia is a recessive trait in humans. In a cross between two parents who are heterozygous.a. Trueb. False
Answer:
True
Explanation:
This is because in the two hetero zygote parents the SS traits are dominated by the dominant A geneotype. Therefore in the AS parents the S-genotype could not manifest, and therefore recessive.
However,when the two recessive genes are crossed in the parents at meiosis 1,the recessive genes were randomly selected to give the SS genotype to the parents.This is an example of autosomal recessive pattern. The chances of inheritance of the gene for the two parents is 25% based on Mendelian's patterns
it is an inherited disorder in which the the percentage of normal biconcave shape Hb is low in the blood, but more of sicked shape ,therefore given the blood of the individual sickle shaped RBCs. It is due to genetic mutation due to single nucleotide substitution of amino acid Glumatic acid with Valine.
The reduction of the surface area for the transport of oxygen,leads to the deficient oxygen supplies to the tissues,and clogging of blood vessels by sickle rbc leading to pains

Fibers used in textiles can be either natural or synthetic. Cotton and Linen are different variants of cellulose fibers. Wool is natural polyamide (protein) fiber. Nylon and polyester are variants used in synthetic fibers. There are 35 kinds of amino acids used in making proteins, and most proteins have 50-1000 amino acids in the chain. What does this say about the number of different kinds of proteins available in nature
Answer:
Proteins are very varied, and the number of junctions and the arrangement in which these junctions are found depends on this.
In addition to taking into account the amount of amino acids.
Explanation:
Proteins in nature are found in great variety, this is due not only to the amount of amino acids present, but the multiple combination options between these amino acids, we must not ignore the unions, that is why some proteins are more complex what others.
Proteins have different unions and this makes it have different coformations, there are primary, secondary, tertiary and quaternary unions, if the protein has all these unions it is considered complex, whereas if it has the simplest it is considered a simple protein.

There are lots of harsh and cruel farming methods that are very harmful to crops and animals, If not well controlled these farming method could pose a very serious threat to crops and animals thereby leading to shortage in food supply.
These methods include;
- Uncontrolled dumping of waste; waste products from farm animals should be dumped properly to avoid contamination and spread of diseases.
- small farm space; a lot of farmers today do not have enough land/fields where animals can roam free, these animals are secluded to a tiny space causing cross contamination between these animals
- giving growth hormones to farm animals is also a very bad practice, these animals should be allowed to grow at their own pace.

A recessive allele inherited in a Mendelian manner causes the disease cystic fibrosis. A phenotypically normal man whose father had cystic fibrosis, and a mother who comes from a long line of non-affected people, marries a phenotypically normal woman from outside the family. If the frequency in the general population of heterozygotes for cystic fibrosis is 1 in 25, what is the chance that the couple's first child will have cysitc fibrosis
Answer:
The chance that the couple's first child will have cystic fibrosis = 1/100
Explanation:
Since both parents are phenotypically normal, it means that they are both heterozygous for cystic fibrosis.
The probability of a cross of two heterezygotes for a recessive allele to produce an offspring having two recessive alleles is 1 : 4 in accordance with Mendelian inheritance.
The initial probability of the couple's first child to be have two allelic pairs for cystic fibrosis = 1 : 4.
However, the frequency in the general population of heterozygotes for cystic fibrosis is 1 in 25.
Therefore, the chance that the couple's first child will have cystic fibrosis = 1/4 * 1/25 = 1/100
