fiasKO [112]

<u>Answer</u>: option B they have a random gene mutation that affects their fur colour.

<u>Explanation</u> :-

  • <em>Variation</em> is the phenomena which occurs in all populations.
  • These variations result in slight differences in the phenotypes of individuals .
  • These variations only arise due to <em>random mutations </em>that arise in the individuals’ genome and then can be inherited by their offspring.
  • There is always a probability of one particular trait to make the individuals survive better in the environment as compared to other trait.
  • The individuals having the trait that helps them to survive better in the environment tend to survive more and leave more progeny. This is termed as <em>survival of the fittest</em>.
  • Thus, according to the question it can be inferred that the dark fur colour arose due to a <em>random mutation </em>since it is the only source of variation. Since, in the given environmental conditions the mice having the dark fur colour were less susceptible to the predators they are better fitted to survive.
  • The dark brown fur coat mice, survive better, leave more progeny and hence, increase their population with time. However, the orginal source of origin of this trait was a random mutation. Had this mutation not occured, the dark coloured fur mice would not have been there.

So, a <em>random gene mutation affecting the fur colour made the dark coloured mice first appear in the population.</em>

Describes what happens as carbon cycles through the environment. What takes carbon out of the environment? What things put carbo
Citrus2011 [14]

Answer:

Carbon moves through Earth's ecosystems in a cycle referred to as the It is through carbon dioxide gas found in Earth's atmosphere that carbon enters the living parts of an ecosystem. ... To release the energy in food, organisms break down the carbon compounds—a process called respiration.

Photosynthesis removes carbon dioxide naturally—and trees are especially good at storing carbon removed from the atmosphere by photosynthesis. Expanding forests, restoring existing forests and managing forests to encourage more carbon uptake can leverage the power of photosynthesis to convert carbon dioxide in the air into carbon stored in wood and soils. The decompsition of the soil helps create a natural environment which keeps the trees healthy and continuously producing photosynthesis. Direct air capture is the process of chemically scrubbing combustionable carbon dioxide directly from the ambient air, and then storing it either underground or in long-lived products. This new technology is not unlike the carbon capture and storage technology for various emissions sources like power plants and industrial facilities. The difference is that direct air capture removes carbon from the atmosphere instead of consuming emissions.

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.If not for the greenhouse effect, Earth would be an ice ball. So, CO2 and other greenhouse gases are good—up to a point. But CO2 is so good at holding in heat from the Sun, that even a small increase in CO2 in the atmosphere can cause Earth to get even warmer.

Hope this helps :)
