Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
Explanation:
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
Answer:
The primary succession process can take hundreds of years to happen, even in medium amounts of rain and temperature.
Explanation:
The primary succession occurs when a community of plants begins to sprout in areas that have never been occupied by any type of living being. The primary succession occurs, for example, with the sprouting of vegetables in rocky outcrops. These plant species are known as primary species and although they are able to survive, these environments offer few resources for the development of living things. Generally, it takes hundreds and even thousands of years for primary succession to occur, even in environments with average temperature and precipitation.

SARS, Ebola, swine flu, rabies
Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.
<h3>How are fossils dated?</h3>
The process of dating fossils is done by analyzing the sedimentary rocks that are formed around the animal for thousands of years, an analysis is also made of the atoms of the fossil of the animal, to give a certain accuracy to the research data.
With this information, we can conclude that Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.
