Normal urine from a healthy person can be expected to contain all of the following except:
a. Creatine
b. Urobilin
c. Glucose
d. Ammonia
e. Magnesium

Answers

Answer 1

Normal urine from a healthy person can be expected to contain all of the following except: Glucose.

Human urine is mostly made of water (95%). The remaining ions and molecules are urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulphate, ammonium, phosphate, and other ions and molecules in smaller concentrations.

The color of normal urine ranges from clear to light yellow. However, some factors might cause the hue to shift. Foods like beets, blackberries, and fava beans, for example, can colour urine pink or crimson. Furthermore, some medications might cause urine to have vibrant colors, such as orange or greenish-blue.

Urine is often a clear solution varying in color from colorless to amber, but is frequently a pale yellow. Urination color is usually caused by the presence of urobilin. Urobilin is a byproduct of the breakdown of heme from hemoglobin during the elimination of old blood cells.

So that it causes the release of energy in a short time, making these muscles tire quickly.

What is the relationship between an increase in fossil fuel consumption and increased carbon in terrestrial plants

Answers

As we use more fossil fuels, the carbon in terrestrial plants grows until we run out of coal and oil, at which point it peaks and begins to drop.

When fossil fuels are burnt, significant volumes of carbon dioxide, a greenhouse gas, are released into the atmosphere. Greenhouse gases trap heat in our atmosphere, which contributes to global warming.

The rise in total carbon concentration causes an increase in carbon on the ocean surface, which has a detrimental impact on marine life populations. At this rate of emission, the marine fauna and flora will suffer for the next fifty years.

After enjoying a meal of fish and chips, you notice your shirt has an oily stain on it. Why won't the oily stain come out when you dab at it with just water?

Answers

Oil and water don't combine because oil is nonpolar and water is polar. Therefore, when you dab at it with just water after enjoying a meal of fish and chips, you notice your shirt has an oily stain on it.

Oil and water don't mix. They're supposedly immiscible. This is due to the fact that water is a polar molecule, which means that one end of it has a positive charge and the other a negative charge. The reason why water molecules cling together is because one water molecule's positive end is drawn to another's negative end.

A molecule of oil has a non-polar structure. Its charge does not have a positive or negative end, but is evenly balanced.

If a cell is starved for ATP, which of the following pathways would most likely be shut down? a. TCA cycle b. glycolysis c. TCA cycle and glycolysis d. pentose phosphate pathway

Answers

Answer: b. glycolysis.

Explanation:

If a cell is starved for ATP, the TCA cycle would most likely be shut down. The TCA cycle, also known as the citric acid cycle or the Krebs cycle, is a process that occurs in the mitochondria of cells and generates ATP through the oxidation of glucose, fatty acids, and amino acids. However, the TCA cycle is not essential for the production of ATP under all circumstances. In particular, if a cell is low on ATP and needs to produce it quickly, it may rely more on glycolysis, which is a simpler and faster process that can generate ATP even in the absence of oxygen.

Therefore, the correct answer would be:

energy is used, converting ____________ to adp.

Answers

Energy is used, converting ATP to adp.

When one phosphate group is removed by breaking a phosphoanhydride bond, a process known as hydrolysis occurs, releasing energy and converting ATP to adenosine diphosphate (ADP). When a phosphate is taken from ADP to generate adenosine monophosphate, energy is also released (AMP). These three phosphate groups are connected by two high-energy connections known as phosphoanhydride bonds.

This free energy can be transferred to other molecules to favourably affect undesirable processes in a cell. To store energy again, AMP can be regenerated into ADP or ATP by establishing new phosphoanhydride bonds. AMP, ADP, and ATP are continually interconverted in the cell as they engage in biological activities.
