The correct answer is option A , C and D
The earths material is recycled and this can be visualized from the different chain cycles such as nitrogen cycle, carbon cycle , sulphur cycle, water cycle etc. These basic components which constitute all the matter existing on earth are continuously recycled and reused. Likewise the energy obtained from sun is neither created nor destroyed; it is only converted from one form of energy to the other form. Such as heat energy obtained from sun is converted into kinetic energy when it converts water into water vapor.
Ocean I contains about 97% of all water on earth
The right answer is B) gene.
A gene, in genetics, is a basic unit of heredity which in principle predetermines a specific trait of the form of a living organism, as defined in 1909 by Wilhelm Johannsen. From the physical point of view, a gene is a fragment of the determined locus of a DNA sequence.
A gene "parameter" the synthesis of a given RNA, by predefining its structure and, therefore, that of the possible protein or possible polypeptide synthesized from this RNA: this is what molecular biology studies .
These two aspects of the notion of gene are supposed to correspond, one at the physical and molecular level, the other at the level of principle and heredity.
Explanation:
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Is there a right or wrong answer or can it be your opinion?
