Sewage and wastewater.

Explanation:

Using this framework, the three main categories of water pollution are point-source, nonpoint-source and trans-boundary.

Industrialization, discharge of domestic waste, radioactive waste, population growth, excessive use of pesticides, fertilizers and leakage from water tanks are major sources of water pollution

Answer:

wind erosion

- i know this question is older but i hope this helps anyone who may need it. :-)

The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.

Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.

Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

The best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.

Prokaryotic cells are single-celled microorganisms known to be  earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.

Difference between unicellular and multicellular.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Answer:

No, I can't conclude that because there are several factors that influence the expression of a trait (for example, gene drift)

Explanation:

There are several factors that affect the genetic variation of a phenotypic trait in populations with small sizes. Genetic drift is an important evolutionary mechanism by which allele frequencies change in populations, and it is well known that the effects of genetic drift are most pronounced in small populations. Moreover, gene flow -or migration- is an evolutionary factor (stronger in small populations) that is also potentially capable of changing allele frequencies and thus contribute to the overall genetic variation of a phenotypic trait. Finally, environmental factors (for example, abiotic and biotic stresses) may also be associated with the variation of a quantitative trait such as, in this case, ear length.

The answer is B. the number of cycles per second perceived by the human ear

I got this question right :)

The pitch is the number of cycles per second perceived by the human ear. The correct option is B.

The ability to assess sounds as "higher" and "lower" in the sense associated with musical melodies is known as pitch.

Pitch is a perceptual feature of sounds that allows their ordering on a frequency-related scale.

Pitch in physics refers to a sound wave's specific frequency, which is expressed in Hertz (Hz).

There are two ways in which these frequencies match musical notes. high tone: A high pitch is one that vibrates at a high frequency.

Pitch is a perceptual quantity that depends on the listener, but frequency is a physical quantity that indicates the number of vibrations per second. In truth, our ears perceive pitch rather than frequency.

The pitch is how many cycles per second the human ear can detect.

Thus, the correct option is B.

Answer:

Due to isolated before mammals evolve.

Explanation:

There are many endemic plants and birds in New Zealand, but no native mammals because New Zealand is an island which isolated from Gondwana which is a supercontinent about 85 million years ago. Before mammals evolved, the New Zealand splits and go away from the Gondwana. So due to water only those mammals that can swim or fly colonized in New Zealand but not the land living mammals.
