A wave hits an object as shown.
Which kind of wave interaction is shown?
Answers
Answer:
Refraction
Explanation:
The wave interaction shown is called refraction.
Refraction occurs when a wave crosses the boundary between two mediumIn this process the ray becomes bent. The density difference between the two medium accounts for the bending of the rays. When a ray crosses the boundary from a less dense to a denser medium, it is deflected to the normal as the ray slows down.Answer:

Clostridium Difficile (C. difficile) is a type of bacteria that increases its activity with most antibiotic use, and is therefore very difficult to treat. Research shows that the most effective way to prevent the spread of infection is frequent handwashing. However, many people have flat-out refused to wash their hands in hospitals. The government is contemplating passing a policy to make it mandatory for people entering hospitals to wash their hands or else risk not being seen by doctors and being escorted out of the building against their will. Do you think the government should go ahead with this plan?
Consider and discuss the legal, ethical or practical problems that exist for each action option and conclude with a persuasive argument supporting your decision.
Answers
Answer:
The government should not go ahead with this plan.
Explanation:
If the government decides to proceed with its plan to pass a law that authorizes the management of a hospital to force people who refuse to wash their hands out of a hospital and deny them medical care against their will, then the government will be infringing on people's right to life. While it is necessary to prevent the spread of Clostridium Difficile (C. difficile) , any law that is made to that effect must not abuse the right of access to medical care which is a fundamental right of citizens. This action will be ethically incorrect because it amounts to a government using a high handed approach in discharging its duties.
However, the intention of such a law is to protect the citizenry from the bacteria Clostridium Difficile (C. difficile) . If such a law is not passed, more people may become infected by the bacteria owing to the carelessness of other people. This situation is made worse because the organism is resistant to antibiotics.
However, since prevention of the spread of Clostridium Difficile (C. difficile) is Paramount, I opine that the government should continue to enlighten citizens and appeal to them on the need to practice regular hand washing in order to protect themselves and other people. Passing the said law is a draconian approach to the problem hence it is not in line with the ethics of modern civilization.
It is more civil to continue to appeal to citizens and sensitize them on the importance of regular hand washing as it affects the spread of Clostridium Difficile (C. difficile) .

In tomatoes, red fruit color is dominant, R, to yellow fruit color, r. A farmer has tomatoes that produce either red or yellow tomatoes. He has signed a contract with a large seed company to provide pure, RR, and pure yellow seeds, rr. They do not want any hybrids. How could the farmer tell if his tomatoes are pure or hybrid?
Answers
Answer:
He should perform a "testcross" by crossing the tomatoes in question with yellow-fruited plants.
If they are pure, all offpsring will be Red: RR x rr = all Rr
If they are hybrids (heterozygous), half the offspring will have yellow fruits: Rr x rr = 1:1 (red to yellow)

Projected values are only estimates. Can you think of either a natural or artificial factor that could increase or decrease the actual amount of wind energy the United States produces in the future?
Edmentum sample explanation:
Technological advancements in the future could lead to the production of higher-efficiency turbines, which could generate more electricity than originally predicted. Climate changes over time could affect wind speeds in a region, leading to higher or lower energy production.
The factors that would exert influence through the process of natural selection are a natural selection: diseases; artificial selection: and genetic engineering. The correct option is C.
What is natural selection?The strongest survive through natural selection, and the most favored traits endure through evolution. Natural selection is the result of selection pressure on a population's frequencies of a specific allele. Evolution is the process through which, over an extended period of time, new sets of naturally selected organisms emerged.
Future technological developments might result in the creation of turbines with a higher efficiency, which might produce more electricity than was initially anticipated. Wind speeds in a place may alter as the climate shifts through time, which could result in increased or decreased energy output.
Therefore, the correct option is C. natural selection: diseases; artificial selection: genetic engineering.

a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These
Answers
Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Answers
Answer:Cladistics (/kləˈdɪstɪks/, from Greek κλάδος, kládos, "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.
Explanation: Modern taxonomists seek to employ classification schemes that are consistent with the underlying evolutionary relationships among species. As shown below, phylogenetic analyses present a way to test existing Linnaean classifications (some of which predate widespread acceptance of the fact of evolution) and to determine which classifications are consistent with evolutionary history, and which require modification.
The pancreas is a human body organ that produces digestive enzymes and two very important hormones : insulin and glucagon. These two hormones work together to regulate the level of the sugar glucose in the bloodstream. If glucose levels in the bloodstream are too low, the pancreas secrets glucagon which causes the glucose level to increase. if blood levels are too high, the hormone insulin will lower the glucose level. if a person has just eaten a meal containing a large amount of sugar and other carbohydrate, which statement best describes how the pancreas will respond.

Cells are the basic unit of structure of living things.
Cell parts such as chloroplasts are self-replicating.
Answers
Answer:
Cells such as chloroplasts are self replicating
Explanation:
a chloroplast is not a cell its an organelle.
Cell Theory is a scientific theory proposed by Schwann in the year 1839. The cell theory has primary three postulates, which are used to describe the functioning of cells.
The correct answer is:
Option D. Cell parts such as chloroplasts are self-replicating.
The postulates of the cell theory are:
1. The cell theory states that all living cells arise from pre-existing cells.
2. The cells are the basic structural and functional unit of life.
3. The hereditary information is passed on from cell to cell, and the energy flows within the cell.
Thus, the statement that is not a part of cell theory is that chloroplast are self-replicating.

Answers
Explanation:
1. The population of the pray that snakes feed on would grow
2. The predators that feed on snakes may die out
if the snake was removed from this food chain, the population of the prey that snakes feed on would grow and the predators that feed on snakes may die out. Remains of other organisms build up in an ecosystem if the decomposers are absent.
How each organism is important for the food chain?Each creature in the food chain depends on an earlier link in the chain. When a creature is eliminated from the food chain, the ecosystem's energy and nutrient cycles are disrupted.
The stability of the food chain is upset. As a result, the species that rely on other organisms for nourishment will starve to death.
The remains of other organisms build up in an ecosystem if the decomposers are absent.
Therefore, the ecosystem becomes unbalanced because the nutrients are not returned to the source to be used by the producers.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.
Answers
Answer/Explanation:
It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

A hand sanitizer was advertised to be more effective at killing bacteria than any antibacterial soap. Students were split evenly into 4 groups to test this claim. Groups 1-3 washed their hands using the assigned hand sanitizer or soap (see table) and warm water for two minutes, and then dried their hands with a paper towel. Group 4 rubbed their hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then dried their hands with a paper towel. After washing, each student’s hands were swabbed and the swab was applied to a culture plate and incubated. Finally, the bacterial cultures were counted. what is the independent variable?
Answers
Answer:
Group 4
Explanation:
The control group in this case would be those students in group 4.
The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.
In this case, group 4 only used warm water for washing their hands instead of the hand sanitizer/soap used by the other groups. Whatever differences found out in the bacterial count in their respective culture swabs can be attributed to the effects of the hand sanitizer/soap.

What are Mendel' law?The following is an outline of Mendel's laws of inheritance:
The principle of dominance is the foundation of the laws of inheritance. The law specifies that hybrid offspring will only inherit the dominant phenotype. The alleles that do not show in an individual are referred to as recessive traits, whereas the alleles that do manifest are referred to as dominant traits.
The alleles for each gene separate from one another during the process of gamete creation, ensuring that each gamete carries just a single copy of each allele for the genes that it contains. This is known as the law of segregation.
The law of independent assortment states that genes for various characteristics might segregate in an unrelated fashion while gametes are being formed.
