Answer:
Option (4)
Explanation:
The earth is comprised of numerous lithospheric plates. This lithosphere is comprised of dozens of major plates and a few minor plates. These plates are constantly in motion over the less dense asthenosphere layer where the rocks tend to flow during deformation. This plate motion takes place due to the creation of convection current in the mantle region as a result of which the plates move under the influence of uprising magma. These currents are formed because of the heat supplied from the core of the earth.
Some of the major plates are Indo-Australian plate, North American Plate, South American plate and the Pacific plate.
Some of the minor plates include the Cocos plate, Nazca plate, and Caribbean plate.
Thus, the correct answer is option (4).

Explanation:
Because people who answer first tend to rush their answers and not do a clear explanation, they often get less recognition than the second person, who usually puts more effort into their answer. The example you gave is an example for that, as the second person has an explanation and more words.
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
Answer:
The paraphrase consists in saying with simpler words and with less technical words those obtained from a text. In this way, it facilitates its understanding, because the original information extracted is expressed in a simpler way.
The correct way to paraphrase is 2. Every organism must acquire and use energy to build new structures, repair old ones, and reproduce
Explanation:
That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation
