Biology
1 answer:
Phantasy [73]1 year ago
6 0

The guppies evolved at a rate between 3700 and 45,000 Darwin's. For comparison, artificial-selection experiments on mice show rates of up to 200,000 Darwin's while most rates measured in the fossil record are only 0.1 to 1.0 Darwin.

Guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in guppies that colonized a high-predation

With each generation, more guppies passed on the gene for small spots to their offspring. The rocks became smaller. More guppies with small spots survived long enough to pass on the gene for small spots to their offspring the rocks became smaller.

Which behavior can reduce pollution that occurs due to the use of coal?
mixas84 [53]

Answer:

A

Explanation:

Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand.

Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and  improving natural lighting indoors.
