Answer:
As you move from red to violet, the wavelength decreases and energy increases.
Explanation:
Here are the 7 from shortest to longest wavelength. Violet - shortest wavelength, around 400-420 nanometers with highest frequency.
hope it helps :)
Answer:
Out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Explanation:
As we all know, that rate of diffusion is linked to the surface area--to--volume ratio. Larger surface area--to--volume ratio depicts that the surface area of an object is higher that than of its volume. The higher surface area provides higher area for diffusion.
Thus, any smaller object with larger surface area--to--volume ratio will provide higher diffusion rate and hence the time for diffusion will decrease.
While any object with smaller surface area--to--volume ratio will provide lower diffusion rate and hence the time for diffusion will increase.
Thus, out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Answer:
D) Endocrine system
Explanation:
In some cases, the nervous system directly stimulates endocrine glands to release hormones, which is referred to as neural stimuli.

Answer: Fossil records help provide clues to the history of Earth's organisms. They've have given scientists clues needed to determine a present day organism's ancestry by comparing them with fossils. Fossil records also show that life has evolved from simple to complex; for example, fossils deeper into the ground (older ones) are much more simple than the ones at the top (newer ones), again supporting the idea of evolution. Fossils additionally show us how behaviors have evolved, how long individuals lived, and how features evolved over time.
