Answer:
Voltage-gated Ca2+ channels
Explanation:
Modulation of Ca+2 channel Epinephrine also causes an increase in cAMP that stimulates PKA that is protein kinase A, which in turn phosphorylates the voltage-gated Ca+2 channel that is the L channel. This phosphorylation results in a protein conformational change that enchances the channels activity.
The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.
<span>One of the essential early steps in the inventing process is creating a prototype--which, simply defined, is a three-dimensional version of your vision. Creating a prototype can also be one of the most fun and rewarding steps you'll take. That's because developing a prototype gives you the opportunity to really tap into your creativity, using those skills that inspired your invention idea in the first place. And whether you're making your prototype at home or hiring the services of an engineer, seamstress or machinist, it's truly exciting to see your idea transformed into something tangible and real.</span>
