Answer:

1) Every planet's orbit is an ellipse with the sun at a focus.

2) A line joining the sun and a planet sweeps out equal areas in equal time(s)

3) The square of a planet's orbital period is proportional to the cube of semi major axis of it's orbit

More solar energy reaches the equatorial regions than the polar regions because the equatorial regions

The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator changes very little through out the year and has summer like conditions for most of the year.

However the other regions may receive direct sun rays but for far more limited periods. In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most direct rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.

List two additional populations (other than those listed in the lab) for which

Indirect methods like mark and recapture become a strong tool to estimate population size or density in species on which it is impossible to apply a direct methods. Because of their biological and ecological characteristics, the Gypsy moth and the Green lizard populations are good examples for which mark and recapture would work well.

------------------------------------------------------

There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the Mark-Recapture technique.

The Mark-Recapture technique assumes that

the population is closed during the sampling season, there is no mortality nor natality,
marks in the individual last the whole sampling season, and they do not affect the marked individual or their behavior.
marked individuals are randomly distributed in the population, and
all the individuals have the same probability of being sampled.

The method consists of capturing a sample of individuals belonging to the population under study. After capturing the individuals, the researcher marks and releases them again. The third step is to sample again: The researcher captures new individuals and counts how many of them are marked. These marked individuals belong to the first sample.

Indirect methods like this become a strong tool to estimate population size or density in species on which it is impossible to apply a direct method such as counting individuals.

For instance, if we need to estimate insects population density (Gypsy moth population) or reptiles population density (Green lizard population) because of their biological and ecological characteristics, the best way of doing it is by applying indirect methods. These species characterize as small-sized, fast to escape, they can hide in small inaccessible places, they have nocturnal habits, their reproductive rate is too high, and their distribution rate is wide. Among many other characteristics, their population density can not be estimated by direct methods. Mark-Recapture technique is the most suitable one.
