what is the best example of a point source pollution
Answer:
Waterborne pathogens in a local river.
Explanation:
Waterborne pathogens are the diseases that are transferred through water and are the pathogenic agents (often live organisms) that cause disease in the host. Chemical, biological, and other contaminants can all lead to water contamination.
What are the point source pollutions?Point-source Pollution is described as pollution that originates from a single, recognizable source, such as an industrial facility or sewage treatment plant output pipe.
Nonpoint-source pollution is pollution that doesn't come from a single source, or point.
Various signs of waterborne infections can occur. The most typical symptoms of a waterborne sickness are typically diarrhea and vomiting, but there may also be issues with the skin, ear, respiratory system, or eyes.
Therefore, waterborne pathogen are the best example of point source pollution.

The release of water from the vacuoles of the cells caused the plant to wilt and droop. The in the plant's cells helps the plant to maintain its structure during this period of stress.
Answer:
Vacuole; Cell wall
Explanation:
The release of water from the VACUOLES of the cells caused the plant to wilt and droop. The CELL WALL in the plant's cells helps the plant to maintain its structure during this period of stress.
Vacuoles are organelles which help in the storage of fluids which may include water, digestion and excretion(release) of excess water in the cells.
Cell walls on the other hand helps to provide structural support in plants and usually surrounds the membranes on the outer part.
Assume that cellular uptake rates and drug delivery rates of compounds 1 and 2 are identical. If the proposed mechanism of sensitization by Compound 1 is correct, what cancer cell treatment protocol is most likely to produce the most apoptosis 20 h after treatment?A.
Answer:
The correct option is B: Administration of Compound 1 followed by Compound 2 after 0.5 h
Explanation:
Administering both compounds simultaneously (as suggested in option A) would mean that some cells might be exposed to and interact with compound 2 before being exposed to compound 1. It was observed by the researchers that if the chemotherapeutic agent (compound 2) is given a half hour after giving sensitization agent (compound 1) gives better results.

what kind of bond does carbon usually form from
Answer:
The most common type of bond formed by carbon is a covalent bond in which carbon shares electrons with other atoms. There are three major types of covalent bonds: single, double, and triple bonds. A carbon atom itself can form four single bonds. Since carbon has four valence electrons, it forms covalent bonds with four neighboring carbon atoms.
Explanation:
Carbon most often forms a covalent bond with other atoms. If the bond is with another carbon atom, it is a pure covalent (or nonpolar covalent) bond. If it is with another atom, a polar covalent bond is formed.
The most common oxidation state of carbon is +4 or -4.
Less commonly, carbon forms ionic bonds with other atoms. This occurs when there is a large electronegativity difference between carbon and the other atom.
So, it usually forms covalent bonds. So D.

How might biodiversity in Area 1 change if the new bird species ate small mammals, lizards, and toads?
Knowing that Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The ecosystem will change if a new species is introduced to an unfamiliar ecosystem. If a new species of birds were to eat another animal that was supposed to be eaten by another. The food chain of the ecosystem would be changed drastically. Aka, it might make the lizards go extinct, and can possibly become abundant. Aka, overpopulating and creating havoc within the ecosystem. Thus, causing imbalance.

What accounts for the differences in the properties of the various polysaccharides in the functions/properties of starches, glycogen, cellulose and chitin?
Answer:
The differences between these are the type of union, the order of the union and the complexity.
All are polysaccharides, but their unions are stronger or more complex, thus giving rise to different functions such as structural or energy reserves.
Explanation:
The types of bonds if they are simple, double or triple also influences the different functions.

Consider the cycle of science shown in the diagram. What would most likely cause the cycle to continue? An explanation inspires new questions and the process of making new observations. A fact inspires new questions and the process of making new observations. A careful systematic process is used in experiments to gather observations and data. A fact is established and more data is needed to convince scientists that it is true.
Answer:
The correct answer is : An explanation inspires new questions and the process of making new observations.
Explanation:
New things are being found and created in a logical field due to the "Skeptical nature of people" that is posing the inquiries.
The premise of scientific revolution is that another inquiry can be gotten from the clarification of the previous addressed scientific speculation or hypothesis as the clarifications comprises of the information got after the suspicions, perceptions and related tests. This creates novel thoughts of 'if and but situations" in the psyche which prompts the arrangement of another theory subsequently proceeding with the pattern of an a logical examination.
Hence, The correct answer is : An explanation inspires new questions and the process of making new observations.

Unlike Earth, Mars has lost their atmosphere over time, causing it to become harsh and uninhabitable. What has protected the Earth's atmosphere?
Answer:23
Explanation:
Birds in a desert climate survive on soft parts of cactus. Scientists observed that during a drought, manyof the birds died. The ones that survived had larger beaks and were able to crack open and eat hardseeds that would ordinarily not be used. What trait would you expect to see in the next generation?
Answer:
Larger beaks. This question refers back to Darwin's theory of Natural Selection. "Survival of the fittest" if the birds that had small beaks all died, the only birds that would be left would be the ones with large beaks.
according to the data in model 1, how many males are 181 cm or above in height
Answer:
9 male individuals are 181 cm or above in height.
Explanation:
You will find model 1 in the attached file.
In the model, you can see a pie chart, a bar graph, and a line graph.
The pie graph shows an approximate proportion of males and females with different highs. What is wrong about this chart is that it does not show the percentages of males and females by heigh. Anyway, we can not answer the question with the given information. The bar graph expresses a comparison between males´ and females´ average height, hand length, and knuckles values. According to this graph, we can not know how many males were 181 cm or taller.The line graph shows the distribution of height in bales and females. Females are represented by a continous line, while males are represented by a pointed-line. So we need to focus on this line to answer the question. The Y-axes shows the number of individuals, and the X-axes shows the heights intervals in centimeters. According to the question, we need to look for the interval that belongs to 181 cm and above. So, the interval between 181-185 cm height corresponds to 6 male individuals. But after that interval, we also have 3 more male individuals that are between a height of 186-190 cm. So, in total, we have 9 male individuals that are 181 cm or above in height.diploid cell that contains three pairs of chromosomes designated AA , BB, and CC. Each pair contains a maternal and a paternal member (e.g., Am and Ap, etc.). *In mitosis, what chromatid combination(s) will be present during metaphase
Answer:
The combination of chromatids in metaphase will be :
AmAm
ApAp
BmBm
BpBp
CmCm
CpCp
Explanation:
Maternal and paternal chromosomes are now in metaphase so it means they would have duplicated as during prophase chromosomes split into chromatids. however, There is no tetrad in mitosis and move to the equator.
So, maternal and paternal chromatids will not mix or pair with one other. Therefore. the combination of chromatid pairs that will be present during metaphase are:
AmAm
ApAp
BmBm
BpBp
CmCm
CpCp
