Explanation: the ice age posed a new chalenge to deer mice and on the ice the preadators could spot the darker deer mice better than the light deer mice.
1) The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure. The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene DNA encoding it.
Answer: receives the thermal energy
Explanation:
The cryosphere can be defined as the land which is covered with the surface of ice in the solid form in the form of sea ice, river ice, snow, ice glaciers, ice sheets, frozen water, and others. When the ice on the land receives the thermal energy from the sun or any other source like radiation then it melts into water and it becomes the part of the water body in the form of the hydrosphere.
There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity.
Assigning each example to the universal muscle characteristic being described;
Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber.
Contractibility; Shortens when stimulated
Elasticity; Returns to its original resting length after being stretched,
Extensibility; capable of being stretched between contractions.
Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
For the answer to the question above, the answer is simply a "Scientific Theory"
<span>it is a well-substantiated and well-presented explanation of the natural world, it is based on repeatedly confirmed through observation and experiment of the said phenomena. These are not the wild guess but reliable facts of the real world events.</span>
