Answer:
Yes, binary fission is an example of mitosis.
Explanation:
Answer: . all of the above
Explanation:
Science has benefited the society by contributing to wide areas of scientific fields like their contribution in medical science, invention of alternative sources of energy, and technological advances.
Medical science: Scientists have conducted many research in order to determine the cause of diseases and their possible diagnostic treatments.
New energy: Scientists have found out energy harnessing technology from renewable resources like water, sunlight and biomass which can meet the energy requirement of human society when conventional resources will not be available.
Technological advances: Scientists have contributed to the development of diversity of machinery which can reduce the human labor.
A signal reaches a cell mostly in the form of a signalling molecule binding to a receptor on the cell surface. This binding activates a chain of events that amplifies the signal and transfers it inside the cell. Protein kinases phosphorylate proteins and cause their activation or deactivation, or in general modify their activity. When a signalling molecule binds to a receptor, a cascade is activated and the second messengers, such as cAMP, are synthesized. cAMP molecules activate the protein kinases, which phosphorylate specific proteins and activate them.
In this case, it is given that <em>Mycoplasma pneumoniae </em>lacks cell wall. some antibiotics such as penicillin works by interfering the synthesis of the cell walls. As these microbes do not have cell wall, the penicillin like antibiotics would not work.
In this case, the antibiotics, which interferes with the DNA (deoxyribonucleic acid) formation and replication can work. The ciproflaxin is an antibiotic, which work by inactivating the enzyme required for DNA replication in bacteria. Hence, the antibiotic ciproflaxin would be effective for treating the given condition.
I believe the correct answer would be B. Semipermeable means that it allows certain substances to pass through, and certain other ones to not pass through. So given all of your options, I would say that B makes the most sense. Hope this helped!
