Answer:
SARS- CoV- 2 is a virus that infects human by the oral-respiratory way in which the virus enters the body and these viruses have spikes on their surface made of spike proteins that allow these viruses to bind with the infected cell.
The infected cells have ACE2 receptor that is protein present on the surface of the human cells. Binding allows the structural change in the virus to fuse and enter in the cell where viruses reproduce them selves with the cell with cell system.
The cyanobacteria from places like volcanic pools so important for the production of oxygen in our atmosphere because oxygen slowly reacts with bacteria and r<span>elease Oxygen. Thank you for posting your question here at brainly. I hope the answer will help you. </span>
Answer:
The correct answer is - D) Glucose – a sugar found in blood that can be broken down to produce ATP
Explanation:
Insulin is a hormone produced by the beta cells of pancrease that takes up the glucose from the bloodstram and make gucose available to the cells of the body to produce energy by the process of cellular respiartion. Glucose is breaken down to its smaller units and produced high amount of energy in the form of ATP. Glycogen is form of sugar that is stores in the muscle and othe cell for the energy in abscence or low glucose level in blood stream. ADP is a molecule know as adesnosine pyrophosphate or diphosphate which is play role in flow of energy. ADP molecules requires energy to form ATP molecule and when ATP splits into ADP and Pi releases high amount of energy.
Answer: The current predicted doubling time is 61years which makes 50years in your option the nearest possible answer.
Explanation:The world's current (overall as well as natural) growth rate is about 1.14%, representing a doubling time of 61 years.
We can expect the world's population of 6.5 billion to become 13 billion by 2067 if current growth continues.
