Fossils can provide ......information about the entire evolutionary process....
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.

Answer:
Photosynthesis is the process of converting light energy into chemical energy in the form of glucose, in small structures called chloroplasts. The glucose made in photosynthesis is then used during cellular respiration.
Answer:
1. The benefits include safer and more efficient nuclear power plants. The kind of energy that is produced is clean with no greenhouse gases and the cost of operating a nuclear power plant is inexpensive. 2.In terms of the disadvantages of uranium, it can have deleterious health effects and can lead to death because of its radioactivity. Radioactive waste is also an additional issue, if it is not disposed of at a safe place and not stored properly, it can leak radiation. Such emissions can last for centuries.
3. It produces no greenhouse gases or other waste and Tides are easily predictable. 4. High tidal power plant construction costs, Negative influence on marine
Explanation:
Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
Probability is the greater or lesser possibility of a certain event occurring.
In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:
total number of possible cases= 48 + 30 + 67= 145
The number of favorable cases for a moth to be brown is: 48
Then the probability that a moth is brown is calculated as:
= 0.33= 33%
On the other side, the number of favorable cases for a moth to be yellow is: 30
Then the probability that a moth is yellow is calculated as:
= 0.21= 21%
In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
