Answer:
D). They move electrons to the electron transport chain.
Explanation: Just took the quiz
NADH and FADH₂ are necessities in the electron transport chain because: They move electrons to the electron transport chain. (Option D)
NADH (nicotinamide adenine dinucleotide) and FADH₂ (flavin adenine dinucleotide) are molecules that play a crucial role in the electron transport chain (ETC) of cellular respiration. These molecules are electron carriers that are generated during earlier stages of cellular respiration, such as glycolysis and the citric acid cycle.
In the electron transport chain, NADH and FADH₂ donate the electrons they have gained from the breakdown of glucose and other molecules. These high-energy electrons are then passed along a series of protein complexes embedded in the inner mitochondrial membrane. As the electrons move through these protein complexes, their energy is used to pump protons (H+ ions) across the inner mitochondrial membrane, creating a proton gradient.
The proton gradient generated by the movement of electrons is used to drive the enzyme ATP synthase, which synthesizes ATP (adenosine triphosphate) from ADP (adenosine diphosphate) and inorganic phosphate. This process is known as oxidative phosphorylation.
In summary, NADH and FADH₂ are essential in the electron transport chain because they provide the high-energy electrons needed to establish the proton gradient, which ultimately powers the synthesis of ATP through oxidative phosphorylation.

How do organisms in the rainforest compete for biotic and abiotic factors? (Emergent layer, canopy layer, understory, forest floor?) In the ecosystem. Giving brainliest.
Organisms in the rainforest compete for biotic and abiotic factor by using resources that are available in the surrounding environment.
Competition occurs when the resources are available in scarce or limited amount. When there is an abundant amount of resources, there is no competition between organisms. The organism which is stronger than other organism can use more resources i.e. water, food and space etc and increase its population.
Those organisms which feed on similar food and other resources can compete with each other and the stronger organism will use the resources in large amount.

A boy picks up an earthworm and place it on a white tile. He observed that the earthworm has difficulty in moving forward.
Explain why.
Answer:
A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.
Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.
Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.

A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.
