When we think about the effects of air pollutants we immediately think of respiratory issues. Exposure to one criteria
air pollutant has harmful effects on the cardiovascular system including increased occurrence of heart attack and
stroke. These effects can result in emergency department visits, hospitalizations and, in some cases, premature death.
As expected, exposure to this pollutant is also linked to harmful respiratory effects, including asthma attacks. What is
this pollutant?
Explanation:
This pollutant is ozone, carbon dioxide, sulphur dioxide, carbon monoxide.
If grasshoppers were removed from this food web, which organism would suffer the most, the bird or the baboon?
Answer:
If the grasshoppers are removed from this ecosystem the bird will suffer the most.
Explanation:
On the presented food web we can see a food web that is complex and typical for the African savanna. As in all food webs, one organism is important for the survival of another organism or for the survival of numerous organisms. In this case, we have the grasshopper and its importance in the ecosystem, and which animal will be the most affected if it suddenly was not in this ecosystem anymore.
The bird and the baboon both feed on grasshoppers, but there is one big difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well. This means that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving, and if it doesn't adapt quickly enough to feed on something else it will probably go extinct. The baboon, on the other hand, will be affected but not so dramatically as it will continue feeding on the other food sources, though it might suffer some smaller losses in its population.
If the grasshoppers are removed from this ecosystem the bird will suffer the most.
Why bird will suffer the most?The bird and the baboon both feed on grasshoppers, but there is one major difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well.
This signifies that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving and if it doesn't adjust quickly enough to feed on something else it will probably go extinct.
Thus, birds will suffer the most.

What is a sarcomere muscle?Sarcomeres are rather stereotyped and are repeated in the course of muscle cells, and the proteins inside them can trade-in periods, which reasons the overall length of a muscle to trade. A character sarcomere consists of many parallel actins (thin) and myosin (thick) filaments.
What is the difference between sarcomere and myofibrils?Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide beyond each other when a muscle contract or relaxes.

a cell is placed in solution which has the same solute concentration as the inside of the cell isotonic. because the concentration is the same on both sides of the membrane which direction will the water move via osmosis
Answer:
If a cell is in a medium with the same concentration of solutes with respect to intracellular space —isotonic— there will be no movement of water because there is no osmotic gradient or osmosis.
Explanation:
Osmosis implies the passage of water through a semi-permeable membrane from a place with a lower concentration of solutes to one where the concentration of solutes is higher. This difference in solutes concentration on both sides of the membrane produces an osmotic gradient, where the water will move towards the space with the highest concentration of solutes.
If a cell is in an isotonic medium —the same concentration of solutes inside and outside the cell— there is an equilibrium and the osmotic gradient is non-existent, so there is no movement of water or osmosis.

Which of the following is an example of haploid cells? cardiac cells nerve cells gametes muscle cells
Answer:
Gametes is an example of haploid cells.
Explanation:
Haploid cells are cells that contain a single complete set of chromosomes. Haploid cells in humans and other mammals, are usually the sex cells (egg and sperms) which are also called gametes that are produced during meiosis (a type of cell division). When the egg is fertilized by a sperm, it produces a diploid cell. Gametes contain 23 chromosomes in humans.

what product of the light dependent reaction of photosynthesis is utilized in the light independent reaction
Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.In other cases, researchers use natural experiments in which the dependent variable (typically a measure of organism health) is measured under differing contexts that are not manipulated. Say, for example, that an accidental chemical spill contaminates five ponds. To determine the possible effects of the toxic chemical on frogs, a researcher could compare the hatching rate of frog eggs laid in those five ponds to the hatching rate of eggs laid in five uncontaminated ponds nearby. This would be an example of a natural experiment because concentrations of the toxic chemical in the ponds were not controlled by the experimenter, but rather resulted from the chemical spill.
Drag type of experiment on the left to the example of experiment on the right.
A. Natural
B. Manipulative
1. ______: Blood concentrations of BPA in college students are compared to their recent consumption of canned food items
2. _____: The feeding behavior of fish in streams that receive acidic runoff from strip mines is compared to the feeding behavior of fish in unaffected streams.
3. _____: The deformity rate in baby birds from nests in pesticide-sprayed fields is compared to the deformity rate in birds from nests in unsprayed fields.
4 ______: Tumor development is compared in mice exposed to five dosages of a known carcinogen in the laboratory.
5. ______: Foraging activity levels are compared in tadpoles exposed to four concentrations of toxic metals in the laboratory.
6. ______: Growth of corn plants is compared in field plots sprayed with three different dosage:s of weed killer 7.
7. ______: BPA concentrations in the urine of people with diabetes are compared to BPA concentrations in the urine of people without diabetes
Answer:
1. Natural
2. Natural
3. Manipulative
4. Manipulative
5. Manipulative
6. Manipulative
7. Natural
Explanation:
1. Checking the blood concentration of BPA in college students in relation to their recent consumption of canned food items is a natural experiment because BPA concentration in blood is not artificially controlled by any means.
2. Comparing the feeding behavior of fish in streams with acidic runoff to that of fish in an unaffected stream is a natural experiment due to the fact that the acidity of the stream is not artificially controlled in any way by the experimenter.
3. Checking the deformity rate in baby birds from nests in pesticide-sprayed fields and that from unsprayed fields would require some manipulations except a sprayed and unsprayed one already existed long before the experiment was given birth to. Otherwise, the sprayed field might need to be artificially created just for the purpose of the experiment.
4. A known carcinogen would need to be administered to a group of the mice. This is manipulative.
5. The tadpoles would need to be artificially exposed to the toxic metals in the laboratory. Manipulative
6. The spraying would need to be carried out artificially in order for the comparison to be made. Manipulative
7. People with diabetes cannot be artificially created. They must have existed naturally long before the experimental design. Natural
why does a person living at a high altitude need large amounts of red blood cells
Answer:
The effects of high altitude on humans are considerable. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 meters (6,900 ft) above sea level, the saturation of oxyhemoglobin begins to decrease There’s oxygen in the air at high altitude. An increase in red blood cells in their bodies allows people to increase their body oxygen levels, especially when they perform strenuous exercise at high altitudes. Many athletes will train at high altitudes in preparation for competitions at lower altitudes. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 meters (26,000 ft) as the death zone, where it is generally believed that no human body can acclimatize

What areas can act as carbon sinks?
the atmosphere
O the Arctic and Antarctic
O oceans, soils and forests
O all of these
Answer:
O oceans, soils and forests
Explanation:
A carbon sink absorbs carbon from the environment. They do not release carbon to the environment.
The atmosphere is a good carbon source since it contains a significant amount of carbon dioxide gas.
Carbon is found in the ocean in dissolved form. Soils are also good carbon sinks. Forest trees use carbon for their life processes One very integral process where carbon is used up is at photosynthesis. The carbon is used to make food materials.i need help with 5-10 please
Answer:
5. C. C6H12O6 + O2 ➡️CO2 + 02 + ATP
6. D. It breaks down glucose to form ATP.
7. D. All autotrophs are producers
8. D. All 4 statements are correct.
9. False
10. False
Explanation:
The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.
In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.
How is the process of photosynthesis essential to sustaining life on Earth?
Answer:
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
... The importance of photosynthesis in our life is the oxygen it produces.
Answer:
without the process of photosynthesis, plant would not be able to provide glucose (the food they consume) and in turn, they would die. Plants also produce )2 as a byproduct of photosynthesis which humans depend on so they we breathe.

Does anyone have an answer for this???
Answer:
because the truck is moving
Explanation:
the force of the engine is bigger than the fractional force so the truck keep moving and do not stop.
Answer with Explanation:
The forces are unbalanced because the engine force (bigger force) and the friction force (smaller force) are not equal. Their difference in force is 40 N. This makes the truck move forward or in the direction of the bigger force. Its movement is being slowed down by the friction force.
Both of the forces are acting in opposite directions, but they are not equal in magnitude. Such occurrence can make an object either slow down or speed up. It could also change its direction. This is in accordance to "Newton's First Law of Motion."

Describe the circumstances of a solar eclipse.
A solar eclipse happens when the Moon passes in front of the Sun and casts a shadow across Earth.
For a total eclipse to take place, the sun, moon and Earth must be in a direct line. The second type of solar eclipse is a partial solar eclipse. This happens when the sun, moon and Earth are not exactly lined up. The sun appears to have a dark shadow on only a small part of its surface.
