When a nerve impulse reaches the end of an axon, the axon terminal released ACh into the synaptic cleft. 2. ACh diffuses across the cleft and attaches to the ACh receptors on the sarcolemma of the muscle fiber. 3. ACh binding triggers electrical events that ultimately generate an action potential.
They are kinda like catalysts
The correct answer is b. no additional nucleotides would be added to a growing strand containing that nucleotide.
<span>
Nucleotides without a 3’hydroxy group are called dideoxynucleotides (ddNTD). Dideoxynucleotides are inhibitors of DNA polymerase because after being added in PCR reaction no further nucleotides can be added as no phosphodiester bond can be created (usually 3' hydroxyl group of the previous nucleotide attaches to 5' phosphate of the current nucleotide).</span>
Answer:
<em>A. The air pressure in that section of Earth’s atmosphere decreased.
</em>
Explanation:
In the free air, the density of the air diminishes as the air is warmed. On increasing the pressure, the density also increases. The air is packed. The density increments as pressure increments.
The thickness and density of air decline with the increase of height because of that the surface area of the Earth's climate diminishes with increase in height, along these lines gas particles can spread out.
The density of the air is most minimal at a high rise on a hot day when the pressure of the atmosphere is low.
"Dave", the feathered lizard fossil is thought of as a(n)<u> </u><u>homologous</u> species, or an organism that may represent a common ancestor shared by different but related lineages of organisms.
<h3>What is homologous evolution?</h3>
Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.
Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.
