A researcher wanted to know if attractive people are more likely to receive help when in need, compared to unattractive people. if the investigator randomly assigned participants to groups that involved an attractive confederate versus an unattractive confederate, such a study would involve 'imdependent' variable.
What is the factor on which physical activities depend?Physically attractive defendants will receive shorter prison sentences than physically unattractive defendants. In an experiment, the hypothesis is an assumption that the researcher makes and that will be tested during the execution of the experiment. This assumption is created from the researcher's observation about a certain situation or element.
In the case of the experiment presented in the question above, we can see that the researcher observed that physically attractive or unattractive defendants have different sentences after the trial. From this, this researcher created a hypothesis, he assumed, that physically attractive defendants will receive lower sentences than defendants who are not physically attractive.
Therefore, A researcher wanted to know if attractive people are more likely to receive help when in need, compared to unattractive people. if the investigator randomly assigned participants to groups that involved an attractive confederate versus an unattractive confederate, such a study would involve 'imdependent' variable.

Individuals from each species each have a certain set of physical traits.
One individual will have a set of traits that is more suited for their environment and will survive (where as the less suited ones will not) and very very slowly overtime that particular species will evolve into another species, or evolve.
Darwin’s point was that basically, every species that is alive today was not “created” individually, but evolved from simple life forms to more complex and diverse life forms.

How does water form during cellular respiration?
Answers
Answer:
The electron transport chain is the third and final step of cellular respiration. Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.

How is a species’ population dynamics affected by the presence of another species with the same niche?
Answers
Answer:
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.
Two species would be in direct competition for the same resources if they both occupied the same niche. According to the competitive exclusion principle, one of the species would inevitably wipe out the other.
What is niche?It defines how an organism or population responds to the distribution of resources and competitors.
(for instance, by growing when resources are abundant and when predators, parasites, and pathogens are scarce) and how it then modifies those same factors.
According to the competitive exclusion principle, often known as Gauss's law, two species that are vying for the same resource in the same habitat but occupy distinct niches cannot coexist at constant population values.
Two species can dwell peacefully in ecological niches without facing any rivalry. It encourages diversity and keeps the food chain in balance.
Therefore, population dynamics affected by the presence of another species with the same niche.

Answer: 10. Control Group
11. Identify the:
Control Group = Subject A
Independent Variable = The new and original itching powder.
Dependent Variable = The type of itchiness.
Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.
The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.
The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.

only produce grayscale images?
Answers
Answer:
See the answer below
Explanation:
The light microscope is able to produce images in their natural color because photons of visible light are utilized as a light source and color is a function of light. Both transmission and scanning electron microscopes are not able to produce images in their natural colors because they utilize beams of electrons to image specimens. They produce grayscale images instead because the regions of the specimen where electrons pass through are usually white while other regions remain black.
