Natural selection, adaptations, genetic variation, and population evolution are all related in terms of changes in phenotypes over
time. Evaluate which statement appropriately describes the relationship between the concepts of natural selection, adaptations,
genetic variation, and population evolution and select the best choice.
A)
8)
Genetic variation exists in a population. Some of the genetic variation
results in different phenotypes. The phenotypes that enhance survival are
called adaptations. Individuals with well-adapted phenotypes are more
Likely to survive and reproduce, leading to population evolution over
generations.
Adaptations exist in certain individuals in a population. The increase in
adaptations causes an increase in genetic variation. The adaptations that
enhance survival lead to larger populations, which further increases
genetic variation. Individuals with well-adapted phenotypes are more
Likely to survive and reproduce, leading to population evolution over
generations.
Genetic variation is high in a population, but random events cause it to
decrease. Populations with fewer individuals and lower genetic diversity
are able to undergo natural selection when selective pressures are high.
The increase in selective pressure causes an increase in adaptations that
are better suited for survival This results in an evolutionary change of a
population
Selective pressures exist in nature and cause changes in a population.
Populations with high selective pressures have higher rates of genetic
change, leading to an increase in genetic variation, Increased genetic
variation leads to some individuals having well-suited adaptations. The
presence of these new adaptations is evidence that the population has
changed, or undergone evolution
o
D)
Answer:
A is the answer
Explanation:
I'm just guessing
Genetic variation exists in a population. Some of the genetic variation results in different phenotypes. The phenotypes that enhance survival are called adaptations. So, the correct option is A.
What is Genetic variation?Genetic variation among members of the same species is called genetic variation. This variation may be due to variations in gene expression, DNA sequence and epigenetic changes. Mutation, genetic recombination, and genetic drift are causes of genetic variation, which can be altered by environmental variables including exposure to chemicals or climate changes.
Genetic diversity is important because it gives natural selection a starting point to work from, helping organisms to adapt and change over time. There is genetic diversity within a population. Different phenotypes are the result of some genetic variation. Adaptations are traits that improve survival.
Therefore, the correct option is A.

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.
The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.
Hope you could get an idea from here.
Doubt clarification - use comment section.
Carbon cycle is a biogeochemical cycle in which the carbon atom continously moves in the atmosphere through different forms and processes.
What is Carbon cycle?The carbon cycle is the biogeochemical cycle which describes the process through which carbon atoms continually travel from the atmosphere to back to the Earth and then back into the atmosphere. This cycle goes on repeatedly. Since our planet and its atmosphere forms a closed environment, the amount of carbon in this system does not change, it only transforms from one form to another.
The processes which takes place in carbon cycle include photosynthesis, decomposition, respiration, and combustion. Carbon cycles from the atmosphere into the plants and living things. For example, carbon is a pollutant in the atmosphere which is present as carbon dioxide gas.
Carbon moves from the plants and animals to soil. When the plants and animals die, their bodies, wood, and leaves decays which being carbon into the ground. Some of this carbon is buried and become fossil fuels in millions of years. Carbon moves from living things to the atmosphere through respiration in which they inhale oxygen gas and exhale carbon dioxide gas.

How is the ecosystem made up?The ecosystem in which we live is coexisting with different types of population. Biotic and abiotic organisms coexist, interdependent organisms that share the same habitat. Through different processes such as predation, symbiosis, parasitism, they will disintegrate and reform to give themselves the energy and nutrient cycle.
The relationship that occurs between the community and its environment will be a flow of matter and energy in the ecosystem. There will also be different types of ecosystems such as marine, terrestrial, microbial and artificial. In all of these there will be food chains between the different species.

Answer:
Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

Photograph of a coal fire.
Carbon is both the foundation of all life on Earth, and the source of the majority of energy consumed by human civilization. [Photographs ©2007 MorBCN (top) and ©2009 sarahluv (lower).]
Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.
Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.
Draft diagram of the carbon cycle.
This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon. (Diagram adapted from U.S. DOE, Biological and Environmental Research Information System.)
Over the long term, the carbon cycle seems to maintain a balance that prevents all of Earth’s carbon from entering the atmosphere (as is the case on Venus) or from being stored entirely in rocks. This balance helps keep Earth’s temperature relatively stable, like a thermostat.
This thermostat works over a few hundred thousand years, as part of the slow carbon cycle. This means that for shorter time periods—tens to a hundred thousand years—the temperature of Earth can vary. And, in fact, Earth swings between ice ages and warmer interglacial periods on these time scales. Parts of the carbon cycle may even amplify these short-term temperature changes.
Graph of oxygen isotope ratios in the deep ocean for the past 67 million years.
The global carbon cycle model describes the evolution of carbon mass in the mantle (Cm), the combined reservoir of ocean and atmosphere (Co+a), the continental crust (Cc), the ocean crust and floor (Cf), the kerogen (Cker), and the biosphere (Cbio).
What are the steps of carbon cycle?Carbon on the dynamic planet can move from one of these realms to another as part of the carbon cycle.
Carbon is transferred from the atmosphere to plants.Carbon is transferred from plants to animals.Carbon is transferred from plants and animals to soils.Carbon is transferred from living things to the atmosphere.When fossil fuels are burned, carbon is released into the atmosphere.Carbon is transferred from the atmosphere to the oceans.Thus, above-mentioned are the steps involved in a carbon cycle.
