The cancer cells exhibit the property of metastasis. Option B is correct.
Metastatic cancer is a type of cancer that spreads from one area of the body to another. Many types of metastatic cancer are also called stage IV cancer. Metastasis is the process of cancer cells spreading to other areas of the body. The cells spread away from the place of origin of the tumor to other parts of the body.
Metastasis involves the following stages: 1. Local Inference of Tumour Cells 2. Transendothelial Migration of Cancer Cells into Vessels 3. Survival in the Circulatory System 4. Extravasation 5. Proliferation in Competent Organ Systems.

b. National coherence and solidarity is implicit in a thorough understanding of the various groups within a nation, and this lack of knowledge about the internal emotions and behavior of the minorities cannot fail to bar out understanding.
c. The fact that there is no demand for incisive and full-dress stories around Negroes above the servant class is indicative of something of vast importance to this nation.
d. I have been amazed by the Anglo-Saxon's lack of curiosity about the internal lives and emotions of the Negroes, and for that matter, any non-Anglo-Saxon peoples within our borders, above the class of unskilled labor.
e. Argue all you will or may about injustice, but as long as the majority cannot conceive of a Negro or a Jew feeling and reacting inside just as they do, the majority will keep right on believing that people who do not look like them cannot possibly feel as they do, and conform to the established pattern.
The correct answer is C. The fact that there is no demand for full dress stories and incisive which is around negroes above, whereby the servant class is indicative of something of vast importance that notion.
Neale Hurston is much confused and surprised by Anglo-saxons. He is not curious about emotions interest.
Educated African American are being perceived as a threat by the white American when author says that all men are like other animals which repels and fears by what he is not understand the difference which is made to decide for a little something.
Answer:C. The fact that there is no demand for full dress stories and incisive which is around negroes above, whereby the servant class is indicative of something of vast importance that notion.

Nutrients from fertilizers, such as nitrogen and phosphorus, can be harmful to aquatic ecosystems primarily because they promote excessive growth of algae and aquatic plants. Hence option b "The increase in algae population reduces oxygen in the water" is correct.
This excessive growth is known as eutrophication. The process unfolds as follows:
Nutrient Input: Fertilizers with nitrogen and phosphorus are often utilized in residential and agricultural settings. These nutrients may be introduced into surrounding water bodies by runoff from these locations.
Algal Blooms: Nutrients function as fertilisers for algae and aquatic plants, causing algal blooms. Algal blooms are therefore created as a result of the fast growth in the population of algae. These blooms can completely cover the water's surface, turning it green or murky.
Oxygen Depletion: The process of decomposition consumes oxygen when the algae and aquatic plants die and degrade. An higher need for oxygen results from the large amount of organic material from the deceased organisms. As a result, the amount of dissolved oxygen in the water may decrease.

Answer: Estuary
An estuary can be defined as an ecosystem where a fresh water source like stream of river get mixed with an ocean. The water in the estuary is brackish water. In estuaries, the water level and salinity rise and fall under the influence of oceanic tides, river flow and seasons. The oceanic tides creates the largest flow of saline water whereas, rivers creates largest flow of fresh water. During rainy season the rivers will flood the estuary with fresh water and in the dry season the estuary shrinks and becomes more saline. Therefore, estuary water varies in degrees of salinity.
Why does the ratio of surface area to volume increase with the decrease in cell size?
A. A larger cell has more surface area than volume.
B. A smaller cell has more surface area than volume.
C. A smaller cell has more volume than surface area.
D. A smaller cell has an equal ratio of surface area to volume
Answer:
B
Explanation:
This is a question more about understanding ratios than understanding cells.
A surface area to volume ratio (S/V) in a size-decreasing cell would increase due to a more significant loss in volume that in surface area. In reality, both decrease (surface area AND volume), but as we are talking about a ratio, this one would go up due to a more dramatic decrease in volume.
