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

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

The myosin and actin could not connect, and the sarcomere would

be unable to contract.

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.

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.

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.

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.

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.

Extraneous Variables

Explanation:

Because they are not an independent variable, but they could affect the results of the experiment.

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."

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.

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.

The change that occurs to the food by your teeth as you chew is both Physical and Chemical. The correct option is C.

Mastication, often known as chewing, is the process of reducing the size of solid food particles so that they can be taken more readily. Teeth are typically used as the surface for biting and grinding.

Chewing masticates, or grinds, food, which aids in physical digestion in the mouth. Salivary amylase, an enzyme that converts complex carbs into simple sugars, performs chemical digestion in the mouth. After the meal has been digested in the mouth, it forms a bolus or ball of food.

In your mouth, chemical digestion begins. Your salivary glands expel saliva into your mouth as you eat. Digestion begins chemically with the help of digestive enzymes found in saliva.

Therefore, the correct option is C. Both Physical and Chemical.
