Ans.

Mesozoic era is a geological era lasting about 252 to 66 million years ago. During this era, gymnosperms were present as dominant vegetation and  dinosaurs were present as dominant land vertebrates.

The first angiosperm (flowering plant) was evolved in Mesozoic era and by the end of Mesozoic era, flowering plants dominated in many regions, although other lower plants, such as ferns were also present in large number.

Thus, the correct answer is option). 'the first flowering plants appeared in the Mesozoic era, not the Paleozoic era.'

Which of the following statements about carotenoids is NOT true? Carotenoids include red, orange, and yellow pigments. Carotenoi
kvv77 [185]

       The right answer to this question is option D. Carotenoids are categorized into two major divisions: carotenes and beta carotenes

       First, let's check option A, it says that the carotenoids include red, orange and yellow pigments, that's true, we can check that on lab for example, a vegetable that can be mentioned here are carrots, it has lots of this and it's very healthy too, and remember, there isn't a single animal that can produce carotenoids, so they need to grab it from nature.

       The second option, B. says that sometimes carotenoids are sometimes called as acessory pigments, that's true too, some studies consider them acessory pigments, so, they're not alone there, there are different kinds of pigments that can be on that plant, and they're also very important for the animals. Option C refers to beta carotene as the most abundant carotene in plants, that's true too, we can also find other kinds of carotenoids on plants, but this one as it's seen in lab, is the most common one. The last one, D, isn't true, the two major divisions are: Xanthophylls and Carotenoids, beta carotenoids are a type of carotenoids, not a different group.

Chlorine in the stratosphere is believed to come primarily from cfcs rather than from natural sources such as volcanoes because:
Andreyy89

 he answer is because <span>samples of air taken over erupting volcanoes shows that volcanoes contribute a small amount of chlorine in the stratosphere compared to CFCs. Volcanic eruptions account for a large instability of chlorine from land to the atmosphere on a yearly basis. This is in addition to chlorine that enters the atmosphere from sea spray, industrial processes and biological gases which are from CFCs. All of these inputs happen near or at the base of the atmosphere. Very little of the material emitted from volcanoes makes it up into the upper reaches of our atmosphere which is the stratosphere where it could touch the ozone layer. However, most of it is believed to be deposited lower down which is in the troposphere, where it then rained out back to the surface of the earth.</span>

Which statement best describes the total energy as it moves through the water cycle?
Artist 52 [7]

The correct answer is option D

The energy in the form of heat is absorbed by the water to convert itself into vapour during the process of evaporation. This energy is then released in the atmosphere when the water vapor gets converted into clouds during the process of condensation. From the start of the water cycle , the heat energy of the sun gets converted into the kinetic energy to raise the water vapour to certain height. After reaching heights Kinetic energy is converted into potential energy and then it is finally released to atmosphere after condensation. In the entire process the total energy remains constant it is just being converted from one form to another.
