Suppose a species lives in an ecosystem with unlimited resources and no predators. What is the shape of its population versus time graph? A. a horizontal line
B. a curve that decreases exponentially as time passes
C. a curve that increases bur flattens out as time passes
D. a curve that increases exponentially as time passes

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.

correct answer is a. and d.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
