Answer:
During the days four through six the population of the dark red beans changed. The change was negative meaning that there was less dark red beans that light red beans. This happened because it was harder to see the light red beans because the color of the air changed. In result of that the zocco ate mostly dark red beans.
Explanation:
Answer:
1) Observation: "I've seen that frog eggs in ponds that receive runoff from farm fields sprayed with herbicides hatch at lower ratesthan those unaffected ponds."
2) Hypothesis: "The hatching success of frog eggs is affected by exposure to herbicides."
3) Prediction: "If frog eggs are exposed to elevated levels of herbicides the hatching success of the eggs will decrease."
4) Test: In the laboratory, raise frogs in pond water with varying concentrations of herbicide, and measure hatching successrates.
5) Result: Analysis of experiment data concludes that herbicide levels affect hatching rates.
The correct answer is - temperate rainforests of the Olympic Peninsula.
The Pacific northwest tree octopus is a fictional animal, thus it does not exist in the present, nor there is any proof that such a creature existed in the past, though there's every chance that it can evolve in the future.
According to the description of this fictional octopus species, unlike the octopuses we know, it is actually amphibious. This basically means that this octopus is able to live in the water, but also be terrestrial. It has developed from the octopuses in the East Pacific, and it started mostly to live on land, or rather on trees. It has used its eight tentacles in order to be able to have a perfect tool and easy arboreal life, swinging from one branch to another, being able to cover longer distances very easily, and manage to hunt with relative ease.
Answer: D) 
Explanation:
If we assume the shape of algae cell is round or sphere.
Given: The total number of algae cells spanning the field of view = 15
At 40x field of view is 
To calculate the diameter of one algae we need to divide
by the total number algae calls spanning the field , we get
The diameter of one algae cell :

Hence, the diameter of one algae cell
