Answer:
Option number 2 is correct. When you talk together in a group during a laboratory exercise, you are engaging in classroom scientific communication.
Explanation:
Any type of communication that is made regarding science is described as a scientific communication. This kind of communication generally involves talks about research, recent advances in any scientific topics or techniques, observations that one might have made on a particular science topic, asking another person about any science-related topic or techniques, etc.
If a scientist talks about any science topic to the public, then it would be a public scientific communication. A scientific communication made among scientists would be termed as professional scientific communication. Any science based communication that is made and kept private would be termed as private scientific communication.
Hence, option 2 is correct. A science based communication between students in a lab would be classroom scientific communication.
Answer:
The correct answer will be option-B.
Explanation:
Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.
The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.
The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.
These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.
Thus, Option-B is the correct answer.
Interferons:
The body releases glycoproteins as the defensive response to virus are called interferons.
The interferons initiate the series of molecular changes and elicit the immune cells to fight the pathogens or foreign particles. These interferons affect the growth of cells and inflammation. Interferons are the cytokines and are responsible for intercellular signalling. The interferons does not directly affect the multiplication of virus instead, it does not let other cells allow virus to use its machinery and replicate. Interferons are of three types: alpha, beta and gamma. The gamma interferon is majorly responsible for the immune response.
