the breathing rate with volume of each breath increases to bring more oxygen into the body and remove the CO2 produced. the heart rate then increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced often in the form of exercise.
Explanation:
I would say B, because the others are actually molecules with other functions, and the plasma membrane is made up of lipids and proteins (mainly lipids). So, the hydrophillic parts of lipids help protect the plasma membrane.
The second law of thermodynamics says that the transfer of energy is imperfect. For example on Newton’s cradle, as GPE is transferee to kinetic energy and back, energy is lost due to gravity forcing the balls down and eventually the motion stops
The Mesozoic Era began roughly around the time of the end-Permian extinction, which wiped out 96 percent of marine life and 70 percent of all terrestrial species on the planet. Life slowly rebounded, eventually giving way to a flourishing diversity of animals, from massive lizards to monstrous dinosaurs.
The Triassic Period, from 252 million to 200 million years ago, saw the rise of reptiles and the first dinosaurs, the Jurassic Period, from about 200 million to 145 million years ago, ushered in birds and mammals, and the Cretaceous Period, from 145 million to 66 million years ago is known for some of its iconic dinosaurs, such as Triceratops and Pteranodon.
