C. Travel at high speeds.
D. Have short wavelengths.
Answers
Answer:
Its A
Explanation:
Its A =Have high amplitudes
Low-frequency waves have long wavelengths. Therefore, option B is correct.
What are waves?
Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.
Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.
Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.

Answer:
Water will flow from microbe to the Jam.
Explanation:
Osmosis is defined as the movement of molecules from higher concentration to lower concentration of the solution across a semi-permeable membrane. In osmosis water moves from low concentration of solute to high concentration of solute.
In the given experiment, cell wall of bacteria acts as a semi-permeable membrane and sugar in jam and cytoplasm in bacteria act as solutes. Sugar in jam is strong solution means has high concentration of solute and cytoplasm in bacteria has low concentration of solute, which drives the movement of water from bacteria to the jam.
Hence, the correct answer is "Water will flow from microbe to the Jam."

Why does light from the sun melt the plastic when light from the desk lamp does not? Because the plastic can take in energy from the light from the sun but not from the light from the lamp. b Because light from the sun carries heat molecules, and light from the desk lamp does not. Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not. Because the sun gives off a type of light that carries erlergy, and light from the desk lamp does not.

This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.
Why the fossils of small skull organisms were found?This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.

Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.The Earth receives ≈174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.Since, 1PW=1000TW
Thus, 174 PW= 174*1000=174,000 TW.

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

How do plants deliver water and nutrients to other parts?Plants deliver water and other nutrients to other parts with the help of vascular tissues like xylem and phloem.
Xylem transports water, nutrients, and other minerals from the soil to all parts.
Phloem mediates the migration of foods from the leaves to the rest of the plants.
The shoot system delivers food to the root system via the vascular tissue phloem. The root system delivers materials from the soil to the shoot system via the vascular tissue Xylem.
