Use the picture below to answer the question. Comparing the two waves, wave B has a...A) higher frequency.B)

Answers

Answer: D) longer wavelength.

Explanation:

A) higher frequency and C) a shorter wavelength.

As far as I know, you calculate frequency on a graph using the number of peaks you can see. Since the wavelength is shorter (the distance between two peaks on the wave), the frequency should also be higher as more fit on the graph.

What is the importance of energy conversion in everyday life?

As an example, food is consumed by humans to store potential chemical energy. When we walk or move in any way, as well as when we speak, we use this energy by converting it to usable kinetic and sound energy. We constantly produce heat energy as a waste, and when we work harder or are under more stress, this heat radiates from our bodies much more.

What does an energy conversion function?

Energy transformations are operations that change one sort of energy (such as chemical, kinetic, or gravitational potential energy) into another. Energy transformation must be a part of every type of energy consumption.

Which of the following is a factor in natural selection?
A. Individuals of species compete with one another to survive.
B. Individuals better able to adapt to changes leave more offspring.
C. All species are genetically diverse.
D. All of the above.

Answers

Answer:

D.

Explanation:

Although all of these answers are similar, it seems that all three are the answer. I am sorry if the answer ends up being B but I'm pretty sure the answer is D. Charles Darwin's evolution theory "evolved", get it, from the natural selection theory. The theory is described as "the process whereby organisms better adapted to their environment tend to survive and produce more offspring." However, some factors that effect natural selection are competition, selection and variation. I believe all three fit the answer and therefore I believe answer D is correct.

The factors in natural selection are Individuals of species compete with one another to survive, Individuals better able to adapt to changes leave more offspring and all species are genetically diverse. The correct option is D.

What is natural selection?

The process in which organisms have adapted to their environment and tend to survive and produce more offspring.

In the natural selection, the species have competition with each other to survive in their adaptation. The diversity in species have their different adaptations. They generally adapt to new changes in their habitation.

Thus, the correct option is D.
