In the United States, most racial discrimination comes in the form of ________ discrimination.
A. Direct
B. overt
C. indirect
D. extra
Answer:
C, indirect because most people do not admit that they are racist and claim that they didn't do things because they're racist.
Explanation:
In the United States, most racial discrimination comes in the form of indirect discrimination. Therefore, option C is the correct option.
What is indirect discrimination?Indirect discrimination involves the policies or practices that appear neutral on the surface, but deep down have adverse effects on the people belonging to a particular race.
Indirect discrimination can be seen in various areas, such as employment. During a job vacancy, the job applicant requires to speak a high level of proficient English which appears to be a reasonable requirement for the job, but it can lead to a significant impact on non-native English speakers.
Indirect discrimination can be seen in the education field where schools give admissions to only those students who will qualify for a specific education test which may seem unfair to students belonging to a specific race, and having different educational backgrounds.
Therefore, indirect discrimination is the most common form of discrimination observed in the United States.

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults
An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result.
Which best describes what occurred?
- Continental shifting resulted in a tsunami.
- Continental shifting resulted in a volcano erupting.
- Tidal activity in the subduction zone caused a tsunami.
- Tidal activity in the subduction zone caused a volcano to erupt.
Answer:
An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result. Which best describes what occurred? Continental shifting resulted in a tsunami.
Explanation:
The best thing that describes the scenario that occurred is tidal activity in the subduction zone caused a tsunami. The correct option is C.
What is tsunami?The violent breaking of rock during an earthquake releases energy that travels through the earth in the form of resonance known as seismic waves.
These seismic waves radiate from the hypocenter in all directions, becoming weaker as they travel further away from the hypocenter.
Tsunamis are a series of large waves with extremely long wavelengths and periods that are usually caused by a violent, impulsive undersea disturbance or activity near the coast or in the ocean.
When a large earthquake ruptures, the faulting can cause vertical slip large enough to disturb the overlying ocean, causing a tsunami to travel in all directions.
Thus, the correct option is C.

explain how darwin's journey to the galapagos islands contributed to his creation of the theory of evolutions.
Explanation:
During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.
Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.

Pls answer now I am giving 40 points
Answer
:proteins
The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.
Explanation:
Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.
Answer:
Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses
