Someone who has broken an arm and has had a cast on it for months will notice a distinct shrinking of the arm once the cast is removed. why does this happen?

Answers

The answer to this question would be : If the muscles are not used they will atrophy.

Muscle cell will adapt to the intensity of the use. If someone uses the muscle to light heavyweight frequently, the muscle will become bigger so it can be used more. If the muscle is not used for a long time, it will slowly shrink.
When a broken arm had a cast, the movement of muscle is prevented so the arm muscle cannot be used until the cast removed.

How the process of natural selection canexplainhow evolution occurs?

Answers

In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.

Answers

The appropriate response is the Olfactory Bulb. It is a mind structure in charge of our feeling of smell. Situated at the tip of the olfactory projection, the knob forms data about smells in the wake of getting tangible contribution from the nose. 


The olfactory bulb is a heap of afferent nerve strands from the mitral and tufted cells of the olfactory globule that interfaces with a few target areas in the mind, including the piriform cortex, amygdala, and entorhinal cortex.
Final answer:

The olfactory stimulus travels from a receptor to the olfactory bulb, which is located at the tip of the frontal lobe. From there, the information is sent to regions of the limbic system and the primary olfactory cortex.

Explanation:

The olfactory stimulus travels from a receptor to the olfactory bulb. The olfactory receptor neurons, located within the olfactory epithelium in the nasal cavity, send signals to the olfactory bulb which is a bulb-like structure at the tip of the frontal lobe where the olfactory nerves begin. From the olfactory bulb, information is sent to regions of the limbic system and the primary olfactory cortex.

Explain why ocean acidification seems to be speeding up, give specific examples.

Answers

Ocean acidification refers to the ongoing decrease in the pH level of the earth oceans which is caused by the uptake of carbon dioxide from the atmosphere. Ocean acidification seems to be speeding up because of the increased human activities which increase the amount of carbon dioxide in the atmosphere.
An example of human activities that speed up the ocean acidification process is the burning of fossils fuels, which continuously release more carbon dioxide into the atmosphere.

How is brain tissue different from other tissues during hyponatremia?

Answers

Final answer:

In hyponatremia, brain tissue responds differently from other tissues due to the presence of neurons, the additional protection of the blood-brain barrier, and the specific osmotic balance required for its function. The excess water induced by hyponatremia causes neurons to swell which can lead to brain damage or death.

Explanation:

The difference of brain tissue from other tissues during hyponatremia is greatly influenced by the brain's unique characteristics and the way it responds to low sodium levels in the body. Hyponatremia is a condition characterised by a decrease in blood sodium levels, which can result from an imbalance of sodium in the body's fluid compartments or dilution of sodium due to water retention. This condition can trigger increased entry of water into cells via osmosis, because the concentration of solutes within the cell is greater than the concentration in the diluted extracellular fluid.

While this water influx can cause swelling or edema in various kinds of cells, it affects brain cells or neurons quite significantly. The brain, as a part of the central nervous system, is packed with neurons which are highly sensitive to changes in their surrounding environment. The excess water entering neurons during hyponatremia can cause the cells to swell. This swelling of neurons in the brain can lead to severe consequences, potentially resulting in brain damage or even death.

Furthermore, the brain is protected by the blood-brain barrier which limits the interaction of circulating materials with the central nervous system. Therefore, the impact of hyponatremia on the brain might be different compared to other tissues because of this additional layer of defence. Additionally, the osmotic balance between water and spinal fluid in the brain is crucial to its function, and any imbalance could lead to critical conditions.

Hyponatremia causes brain tissue to behave differently due to its sensitivity to changes in sodium levels and water balance. The Blood Brain Barrier emphasizes the need for stringent regulation to prevent brain damage. Timely medical intervention is crucial to avoid severe neurological consequences.


In hyponatremia, brain tissue behaves differently compared to other tissues because of its sensitivity to changes in sodium levels and water balance. When the blood sodium decreases due to conditions like water retention or congestive heart failure, water enters cells by osmosis, which can result in cell swelling. Specifically, the swelling of neurons in the brain can be dangerous, leading to brain damage or death. The brain is particularly vulnerable during hyponatremia because neurons cannot accommodate excessive swelling without causing symptoms like nausea, vomiting, headache, and even coma.

Furthermore, the presence of the Blood Brain Barrier (BBB) emphasizes the need for stringent regulation of the brain's microenvironment, including potassium and sodium ions, to maintain neuronal function and prevent brain tissue damage.

What simple chemical test is useful in the identification of the mineral calcite or any of the minerals found in the carbonate group?

Answers

Putting vinegar on it... if it’s from the carbonate group it will bubble

Final answer:

The identification of calcite and other carbonate minerals is typically done by applying a drop of dilute hydrochloric acid (HCl) to a specimen and observing whether it effervesces. Dolomite, another carbonate mineral, react more slowly and may require scratching the specimen to produce a powder. Vinegar and barium chloride solution can also be used for carbonate mineral tests.

Explanation:

A simple chemical test commonly used to identify the mineral calcite and other minerals in the carbonate group involves using dilute hydrochloric acid (HCl). When a drop of this acid is placed on a sample of calcite, it will typically effervesce or fizz. This reaction occurs because calcite, which has the chemical formula of CaCO3, reacts with the acid to produce carbon dioxide gas. If the sample does not fizz, it may be dolomite, another mineral in the carbonate group. In the case of dolomite, scratching the specimen to create a powder and then applying the dilute acid will often result in a slower, more gradual fizz, indicating the presence of this mineral.

Another option for testing is to use vinegar, which contains acetic acid. While the reaction will be less vigorous due to the weaker nature of acetic acid, it can still be used to test for the presence of carbonate minerals. This test is versatile and, in addition to field use by geologists, it is also used in mineral identification labs.

Additionally, magnetite can be identified by its magnetic properties, and distinguishing between sulfates and carbonates can be done by adding barium chloride solution to a test salt, where the formation of a white precipitate can indicate the presence of these groups.
