It constantly moves to readjust the position of the eye.<span>It constantly moves to maintain a steady point of fixation.</span>
The correct answer is: It enters the citric acid cycle and associates with a 4-carbon molecule (OXALOACETATE), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
The citric acid cycle is a cyclic process (part of the cellular respiration) where acetyl CoA is modified in the mitochondria to produce high-energy intermediate molecules for the oxidative phosphorilation (production of ATP).
Acetylcholine receptors<span> are embedded in the </span>sarcolemma<span> at neuromuscular junctions. A neuromuscular junction is where a motor neuron makes contact with a muscle fiber. The </span>sarcolemma<span> is the cell membrane of a muscle cell.</span>
A. direct B. indirect C. direct D. indirect
Competition occurs by direct and indirect means. Organisms interact directly by fighting (aggression) for scarce resources. Two eagles fighting over the salmon carcass and two colonies of ant clashing over a wasp are samples of aggression (direct competition)
Indirect competition happens when there is a common or limited <span>supply of at least one resource (food, water, and territory). </span>Use of this resource lessens and later depletes the amount available to others, or they compete for space.<span> Gray foxes preying on penguins and squirrels relying on nuts for food are samples of indirect competition.</span>
Survival would be correct
