Your answer
More-resistant endospores of themophilic bacteria may survive, but wont germinate and grow under normal storage.
Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.
Explanation:
Answer:
E. bind to troponin which moves the tropomyosin
Explanation:
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction

Answer:
Isolation means that organisms of the same species are separated, and happens when there is something between the organisms that they can't cross.
Explanation:
Organisms become isolated as a result of environmental change. The cause of isolation can be gradual, like when mountains or deserts form, or continents split apart.
