Energy needs Birds because they are warm-blooded and have powerful muscles to beat their wings. Birds must eat food with a high energy content. .the seeds soften and become easier to digest.
The correct answer for this question would be option C. The one that is not deposited by wind is TILL. Till is an <span>unsorted material deposited directly by glacial ice and showing no stratification. Hope this is the answer that you are looking for. </span>
Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.
Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.
The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.
Answer:
Explanation:
Each of these types of scientists focus on different research studies and therefore needs different tools. Field Scientists' studies mainly revolve around observations which they, therefore, need only a pen and paper, this may sometimes change when they need bigger machinery to make a certain event occur, but this machinery is dependent on the type of research. On the other hand laboratory, scientists work with different specimens within the lab and tend to use tools such as Bunsen burner, beakers, reagent bottles, petri dishes, and microscopes.
Seed plants have an evolutionary advantage for several reasons. For one, the seeds can disperse easily. Furthermore, seeds can time their germination. For example, some seeds only germinate when they experience a period of being frozen.
