Answer: B
Explanation: So air, like most other substances, expands when heated and contracts when cooled. Radiation cooling occurs when air near the ground is cooled by the Earth's surface losing heat by radiation.
Answer: Cerebrum
Explanation:
The primary sensory areas of the cerebral cortex receives and processes the somatosensory, visual, olfactory and gustatory information.
Then along with the cortical areas, the brain regions synthesize the sensory information into the perfections of the world.
It is the largest section of the brain which lies in the front or the top of the brain stem.
It is one of the five major divisions of the brain which is most developed.
The correct answer should be (d) The Krebs cycle
After Glycolysis, the Krebs cycle begins in the matrix of the mitochondrion.
The cellular process shown in the image as x, y and z are mentioned below:
X is Replication. It is the process by which double- DNA Replication is the process by which double stranded DNA makes its own copies. Each strand on its separation, synthesizes a complementary stand.
Y is Transcription. It is the process by which copying of the information from a strand of DNA into a new molecule of mRNA, with the help of an enzyme RNA polymerase.
Z is Translation. It is the process in which genetic code on mRNA is decoded to produce the specific sequence of amino acids to form a polypeptide chain.
Answer: Food consumption and production have a considerable impact on the environment. Food production contributes
Explanation: , for example, to climate change, eutrophication and acid rain, as well as the depletion of biodiversity. It is also a considerable drain on other resources, such as nutrients, land area, energy, and water.
