Answer:
Hydrogen and electrons
Explanation:
Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.
For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
Renewable energy is exactly what it says -- it's renewable. Meaning, you can continue to reuse it or make more of it in a never ending cycles. Examples of a renewable energy could be trees (wood). You can keep growing trees and harvesting them.
Fossil fuels are things like oil or petroleum, they cannot be "grown" again, and are a one-time use.
Renewable energy has more benefits then that of fossil fuels because you can reuse renewable energy and keep the never-ending circle of energy going, unlike fossil fuels which can run out.
Answer:
Explanation:
Archae and bacteria are similar to each other in that
1. They are both prokaryotes meaning they do not have membrane bound nuclei and organelles.
2. Presence of flagella in both that helps them to move in their environment by propelling them. The flawless are threadlike structures used for movement
Archae and eukaryotes are similar in that
1. At the molecular level, they use the same molecular machines eukaryotes use in DNA synthesis and other processes
2. Some eukaryotes and the archae use asexual reproduction
Both some studies noted that archea are closely related to the bacteria than to eukarya
Answer:
A protein deficiency causes such diverse symptoms because immune, nervous, and muscle system cells require proteins for structure and regulation.
Proteins are the building blocks of bones, muscles, cartilage, skin, and blood. They also help in transporting oxygen, helps in blood clotting during injuries etc.
Explanation:
Root hair cells absorb minerals and water from the soil.
The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).
I hope this helps
