if your leg was to get cut off where would you feel the pain?

Answers

The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.

Hope it helps you... pls mark brainliest if it helped you

Answer:

The nerve(s) in your leg.

Explanation:

It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.

to the surface - where on the ramp the ball starts from The students do
change the type of surface the ball rolls on. What is the independent

how does the liver help in maintaining homeostasis

Answers

Answer:

The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.

Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.  

Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.

Proteins can be denatured in many ways.
Which of the following will NOT denature
a protein?
A. pH
B. temperature
C. too many enzymes
D. salt content

Answers

Answer:

Explanation:

However, at very high salt concentration, the increased surface tension of water generates a competition between protein and salt ions for hydration. Salts strip off the essential layer of water molecules from the protein surface eventually denaturing the protein

Too many enzymes cannot denature protein.

Enzymes are a type of protein so  they will not get denatured in presence of one another.Enzymes are proteins that speed up any biochemical reaction in the body.

What is denaturation of protein?It is a process of modifying the molecular structure of a protein.It involve breakage of many of the weak bonds within the protein molecule that are responsible for the structure of protein and its order.It can happen due to high temperature, pH, salt concentration and mechanical concentration.

C) Studies show that atmospheric carbon dioxide has increased over the past 150 years.
D) The distribution of many organisms has already shifted as a result of warming.

Answers

Answer: D: The distribution of many organisms has already shifted as a result of warming.

Explanation: I just took the quiz on FLVS

The statement that supports the biological predictions as it relates to change in climate is : ( D ) The distribution of many organisms has already shifted as a result of warming

What is climate change ?

Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.  

As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.

Hence we can conclude that The distribution of many organisms has already shifted as a result of warming  is the correct statement.

Answer:

Heterotrophs

Explanation:

Heterotroph, in ecology, is an organism that consumes other organisms in a food chain. They acquire their energy by the controlled breakdown of preexisting organic molecules, or food.

¹All heterotrophs, use organic materials as their sole source of carbon. Heterotrophs use preformed organic compounds as their source of carbon. (Source: Brittanica)

Metabolic cycles in general—the extraction by organisms of useful ²energy and food molecules from environmental source material—can be described in terms of oxidation-reduction reactions

Heterotrophs can be organotrophs or lithotrophs. Organotrophs exploit reduced carbon compounds as electron sources, like carbohydrates, fats, and proteins from plants and animals. On the other hand, lithoheterotrophs use inorganic compounds, such as ammonium, nitrite, or sulfur, to obtain electrons.

A strain of bacteriophages was grown in BrdU. BrdU is a base analog, that when incorporated into DNA, causes the DNA to fluoresce yellow.
