Answer:
In general, the shapes of viruses are classified into four groups: filamentous, isometric (or icosahedral), enveloped, and head and tail. Filamentous viruses are long and cylindrical. Many plant viruses are filamentous, including TMV (tobacco mosaic virus).
Explanation:
1- The following are the examples of mechanisms which help maintain homeostasis:
- Increase heart rate in response to exercise.
- Insulin secretion in response to high blood sugar.
- Antibodies binding to virus.
2- Correct order is as follows:
- Body temperature exceeds 98.6 degrees F
- nerve cells send message from skin to the brain
- temperatures regulation center in the brain sends out signals
- sweat glands throughout the body activate to cool off skin surface
- body returned to normal temperature around 98.6 degrees F
3- Low blood sugar would likely a stimulus that would cause the body to initiate feedback mechanisms. Because If blood glucose gets too low, the body releases glucagon, which causes the release of glucose from some of the body’s cells. And this is an example of feedback mechanism.
Insert dna in plasmid
plasmid multiply
target cells reproduce
cells produce proteins
Full question:
Which of these is unlikely to happen during the process of sugar breakdown in a cell? A) The products formed are carbon dioxide, water, and energy. B) Energy is released and is used for cell’s life functions. C) Carbon dioxide formed is used by the cell for various activities. D) The starting materials in the process are glucose (sugar) and oxygen.
Carbon dioxide formed is used by the cell for various activities.
<u>Explanation:</u>
The human cells are responsible in making ATP by the process of breaking glucose and the energy is converted into ATP. this process is called as cellular respiration. The main components that are essential for the cellular respiration to take place are oxygen and glucose.
When these components are broken down during the cellular respiration, carbon dioxide, water and energy are produced. This energy is converted into ATP and it is used by all the cells for its function. Thus cells are very important unit in a human body. Carbon dioxide is only a by product during cellular respiration and it is not used by the cells for any activities.
