pollution?
a. Storm water
b. Agricultural Runoff
c. Factory effluent
d. Residential posticide runoff
The BEST example of a point source of water pollution is factory effluent (Option c).
Water pollution refers to the contamination of water with pollutants. These substances (i.e., pollutants) convert water unusable to carry out different activities (e.g., drinking, cleaning, etc).
Water pollutants include, among others, herbicides, food processing waste, volatile compounds, heavy metals, organic pollutant microorganisms (e.g. bacteria, parasites), etc.
Factory effluents are well known to be harmful water pollutants for aquatic ecosystems.

O oxigênio é importante um gás na quebra de ligações entre os átomos que formam a glicose para a produção de energia. Por que a presença de ferro no nosso organismo é importante para este processo?
Answer:
It transport oxygen from lungs to the cells.
Explanation:
The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.

One end of the rope is vibrated to produce a wave with a wavelength of 0.25 m. The
Frequency of the wave is 3.0 Hz. What is the speed of the wave? *
1)3.00m/s
2)2.50m/s
3)0.75m/s
4)1.25m/s
Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.

Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices. What would be the most likely result if some of the species in the coral reef are destroyed? Other organisms would move into the coral reef area ⊝ The coral reef would be allowed to flourish without so many fish and plants living in and around it. ⊝ The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance. ⊝ The waters surrounding the coral reef will become cool with the decreasing number of organisms living there ⊝ CLEAR ALL ❮ PREVIOUS ... 6 7 8 9 10 11 12 13 14 15 ...
Answer: If some of the species in the coral reef are destroyed, (The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance)
Explanation:
CORAL REEFS is a ocean habitat that provides shelter for a variety of aquatic animals such as clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish which are just a few examples of the large variety of organisms that can be found in a coral reefs. These animals are responsible for building the reefs which takes different forms and helps in maintaining balance. This habitat is important to marine life as it provides food and shelter for them.
Recently, many human activities has posed a threat to the coral reef and it's inhabitants These activities include:
--> Pollution: this is cause any agricultural run offs, Chemical and oil spills which can damage coral growth and reproduction.
--> coastal development: an unplanned coastal development has a damaging effect on the coral reef habitat.
--> Sedimentation: This can lead to increase in turbidity of coastal waters which in turn reduces light availability to the coral reef.
--> Destructive fishing practices: inadequate management of different fishing practices has led to the depletion of key reef species and habitat damage.
From the above explanation, the aquatic species found in the coral reef are responsible for building and maintaining the reef. If they are DESTROYED due to the above mentioned human activities, the reef will begin to deteriorate.

How does carbon dioxide in the atmosphere eventually cycle through to a carnivore?
A. Plants use carbon dioxide in the atmosphere during photosynthesis, herbivores eat the plants, and a carnivore eats an herbivore.
B. Carnivores use carbon dioxide in the atmosphere during cellular respiration.
C. Herbivores use carbon dioxide during photosynthesis, and a carnivore eats an herbivore.
D. Plants use carbon dioxide in the atmosphere during photosynthesis, and a carnivore eats the plants.
Plants use carbon dioxide in the atmosphere during photosynthesis, herbivores eat the plants, and a carnivore eats an herbivore.
How carbon move from atmosphere to the biosphere?Carbondioxide gas move from atmosphere to the biosphere by absorbing by the plants in the process of photosynthesis. These plants are the food of herbivores so they eat it and carbon move from plant to herbivore. Then the carnivore feed on the herbivore.
So we can conclude that option A is the right answer.

What is the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz?
Answer:
You multiply 0.5 by 20 which will give you 10 your answer is 10
the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz is 10
what is speed ?Speed can be referred as the ratio of distance to the time in which the distance was covered which is a scalar quantity as it has only direction and no magnitude.
The speed is represented as s=d/t, Where, s is the speed in m.s-1, d is the distance traveled in m, t is the time taken in s
There are four types of speed like Uniform speed, Variable speed, Average speed, Instantaneous speed
Uniform speed is where the object covers equal distance at equal interval of time, variable speed is defined as when the object covers a different distance at equal intervals of times.
Instantaneous speed is defined as an object is moving with variable speed, then the speed at any instant of time is known as instantaneous speed.

The autonomic nervous system works without our control. Which of the following does
cardiac muscle fall under?
involuntary or
voluntary
Answer: Involuntary.
The Autonomic nervous system is a subdivision of the Peripheral nervous system and it is in charge of the involuntary processes in the body such as blood pressure, respiration and the heart rate. As such, its effectors are under involuntary control.
The Autonomic nervous system controls the smooth and cardiac muscles in the body as well as the glands. This is where it earns its other name, the Visceral nervous system.

Calculate the ratio of the size of the bacterial cell to the size of the mesophyll cell
bacterial cell is 1 micrometer
mesophyll cell is 0.05mm
Answer:20 to 1
Explanation:
]
The ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20. It means that 20 bacterial cells can fits into a mesophyll cell.
Given here,
Size of the bacterial cell = 1 micrometer
Size of the mesophyll cel= 0.05mm
Equalize the measuring unit,
1 micrometer = [tex]\bold{10^-^6 m}[/tex]
1 millimetre = [tex]\bold { 10^-^3 m}[/tex]
So the ratio will be
[tex]\bold { = \dfrac{ 1 x10^-^6 m}{0.05 x 10^-^3 m} }\\\\\bold { = \dfrac 1{20} }[/tex]
Therefore, the ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20.

B-Peces
C-Anfibios
D-Aves
es la A
Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres. Cerca de tres millones de años después se produjo la separación, a partir de un ancestro en común, de los linajes que con el tiempo darían origen a las aves y los cocodrilos. El grupo que incluye tanto a cocodrilos como aves se lo denomina Archosauria, que significa ‘reptiles dominantes’.

Landscapes with a faulted and folded surface bedrock structure, steep slopes, and high elevations are classified as
1)mountains
2)lowlands
3)plains
4)plateaus
Answer:
The correct answer is 4. Plateaus.
Explanation:
A plateau is a relatively flat, relatively high-lying part of the earth's surface that is wholly or almost wholly bounded by steeply sloping terrains. There is a pronounced slope on at least one side. The original flat area has mostly risen vertically as a whole due to geological factors. It may possibly have been cut by rivers, giving the impression of a hill or mountain landscape, but this is not it.
