How is The environment on Mars different from that of Earth’s?
Pavlova-9 [17]

Answer:

  • Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth's. The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide.
  • The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth's is rich in nitrogen and oxygen.
  • Because of the differences in atmospheric densities and distances from the sun, the temperature within the atmosphere are also wildly different. Earth generally ranges from 14 degrees Celsius to 70.0 degrees, whereas Mars ranges from -146 degrees C to -140 degrees C.
  • Both planets have a silicate mantle surrounding their cores and a surface crust of solid material.
  • Earth and Mars’ both have terrains that varies considerably from place to place.

When conducting a population sampling study, on the first capture attempt, we _______ the captured individuals.
deff fn [24]

When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.

<h3>What is the mark-recapture method?</h3>

This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.

Thus, option "D" is correct.
