Climate change
Greenhouse effect
Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.
These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.
Increasing carbon dioxide levels
Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.
Global warming
The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.
"The basic difference between dense irregular and dense regular connective tissues is in the amount of elastic fibers and adipose cells present. "
-False Statement.
Explanation:
The basic difference between the dense irregular and dense regular connective tissue lies in the arrangement of collagen fibers in them.
The collagen fibres are arranged parallel to one another in a regular connective tissue while in irregular connective tissue, the fibers are not arranged in parallel manner.
During telophase in mitosis or meiosis II, where chromosomes which were previously distinct and condensed, de-condense and spread out into a tangle of chromatin. At the same time, the nuclear envelope re-forms around each cluster of chromosomes in each of the daughter cells, and spindle fibres disintegrate.
Chromosomes are unlikely to de-condense and spread out into a tangle of chromatin during telophase I (i.e. Telophase of Meiosis I), since Meiosis is still ongoing, and the genetic material should be in its condensed form during Meiosis II as well.
