Answer:
in the geosphere
Explanation:
The drill will eventually stop within the geosphere.
- The biosphere is the region of the earth populated by living organisms.
- The geosphere is the region of the earth made up of solid rock
- The atmosphere is the gaseous part of the earth.
- The hydrosphere is the liquid part of the earth or where water dominates the earth.
The drill pierces through the geosphere as it initially passes through the hydrosphere. Eventually, the drill stops within the geosphere.
Answer:
B. decreases salivation and increases blood pressure
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.
The sympathetic nervous system is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.
Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.
The control of salivary production by the sympathetic nervous system leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.
There are 3 main processes in urine formation. These are Filtration, reabsorption and secretion.
Filtration
Blood enters the afferent arteriole and goes to glomerulus where blood is filtered and it will sip inside the glomerulus and nonfilterable components will go into efferent arteriole.
Reabsoprtion
Molecules and ions will be reabsrobed into the system. The fluid will pass into the proximal, distal and convoluted tubules, loop of henle, as water an ions are removed as the fluid osmolarty changes. Last is secretion of substance that is not filtered.
The main function of DNA polymerase is to synthesize DNA from deoxyribonucleotides, the building blocks of DNA.
