The answer would be A. shivering because it<span> is a bodily function in response to early hypothermia or just feeling cold in </span>warm<span>-blooded animals(or humans). When the core body temperature drops, the </span>shivering<span> reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating </span>warmth<span> by expending energy. Hope this helps!:)</span>
CMB radiation and a very early form of helium were discovered
Redshift of distant stars and galaxies indicate the universe continues to expand.
Explanation:
After the big bang, the remnants of the explosion are perceived mainly in the microwave spectrum ( after photon decoupling phase) that continues to fade as it diffuses across the expanding universe. As the universe expands, it causes the wavelengths of the photons to increase (relative to the observer who will view the galaxies moving away from him in red-shift).
The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
the opposite make an attraction like positive and negative , and negative and positive. if it was negative and negative or positive and positive it wouldn't make an attraction.
