A mutation is a change in the DNA sequence that can be either beneficial or harmful. 1) B, false.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material that introduces new variants.

These changes are unpredictable, and occur due to the action of mutagenic agents that alter DNI sequences.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level.

Mutagenic agents cause changes in the base sequences and pairing.

Many of these mutations are eliminated, but some might succeed and be incorporated into each individual, getting to even affect the entire species.

These mutations are the ones that have been selected by natural selection.

Mutations depend on environmental conditions and ecological pressures, and accumulate in time. Mutations can be damaging or beneficial to the organism and might be inheritable or not.

Those favored by natural selection are inherited by the following generations and get to spread.

The statement is False, Option B.

Outline the four stages of the demographic transition as it occurred in Europe and North America.
Ivanshal [37]

Answer:

Stage 1—High birth and death rates lead to slow population growth.

Stage 2—The death rate falls but the birth rate remains high, leading to faster population growth.

Stage 3—The birth rate starts to fall, so population growth starts to slow.

Stage 4—The birth rate reaches the same low level as the death rate, so population growth slows to zero.

1. Based on your knowledge of how the greenhouse effect works, why does the level of carbon dioxide affect the global temperatur
vova2212 [387]

Answer:

1. Earth's temperature is maintained by re radiated infra red radiation by green green house gases and slightly by water vapors in atmosphere. These gases prevent heat from escaping to outer space, so are functionally comparable to glass panel of green house. Thus, this heating effect is referred to as green house effect. Carbon dioxide is a green house gas so increased amount of this gas in the atmosphere will result in increased atmospheric temperature and global warming.

2. Three sources of atmospheric carbon dioxide are:

  •  Volcanic eruption
  • Respiration by plants and animals
  • Decomposition of organic substance.

Explanation:

  • <u>Overall rise in temperature </u>of the Earth due to excessive amount of green house gases in atmosphere that trap heat radiating from Earth's surface is called Global warming.
  • Global warming can cause melting of ice caps, alteration of seasons, destruction of forest and increase in deserts.
  • Green house gases include carbon dioxide, methane, ozone, nitrous oxide, and nitrogen dioxide etc.
  • Among all these gases Carbon dioxide is the major component that is responsible for global warming.
  • Carbon dioxide is added to the atmosphere by burning of fossil fuels, volcanic eruption and respiration. But Burning of fossil fuels itself adds about 18 X 10¹² tonnes of CO₂ anually.
  • Global warming has become a major environmental concern now and needs to be controlled immediately.
