D because if the species was to be removed from an ecosystem, everything that needed that species as food, or the species ould have to adapt to the foods available in the new ecosystem they live in. Hope I helped, and let me know if you are still not 100% sure about the answer, and I'll try to clarify what I said.
Glaciers leave behind deposits known as glacial till, which are unstratified, poorly-sorted sediments. Glaciers move a wide range of sedimentary particles from small clay-sized particles to large boulders. When the glacier either melts or retreats, these poorly-sorted sediments are deposited.
Like you might have studied. Heated hair expands while colder air contracts. So, the sound isn't able to move as efficiently in cold air than it would in warmer air.
Answer:
The nervous system is composed predominantly of neural tissue.
Explanation: Anatomist study anatomy, the study of the structure of organisms or their parts. By observing the structure of the nervous system, anatomist will tell that it is composed predominantly of neural tissue. So, he observed the structure of one part of an organism.
<u>Answer</u>:
The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and FADH2
<u>Explanation:</u>
The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2. During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC) is also referred as the chemiosmotic phosphorolation.
