When a patient experiences respiratory alkalosis, the
physiological compensation will be what?
Answers
Answer:
Respiratory alkalosis results from excessive ventilation (hyperventilation). In respiratory alkalosis, Pco2 falls, leading to an increase in pH (alkalosis). If the alkalosis persists for more than 12 hours, the alkalosis may be partially compensated by decreased renal H+ excretion. During respiratory alkalosis, HCO3− may fall acutely owing to equilibration with depleted CO2. There is a 2 mEq/L decrease in HCO3− per 10 mm Hg decrease Pco2 that is chemical and not part of the renal compensation. Common causes of respiratory alkalosis include hyperventilation from voluntary effort (anxiety) or stimulation of central respiratory centers secondary to meningitis or a fever.

Energy extraction and the complete oxidation of foodstuffs requires three stages. The energy extracted from fuels is converted to ATP. Select the statements that are true for the different stages required for energy extraction and complete oxidation of foodstuffs.
A. In the first stage, macromolecules are converted to monomers, and a small amount of ATP is produced.
B. In the first and second stages the majority of ATP needed for cellular processes is produced.
C. In the third stage, fuel molecules are completely oxidized to CO2 , and most of the ATP needed for cellular processes is produced.
D. In the third stage, fuel molecules are completely oxidized to CO2 , and a small amount of ATP is produced.
E. In the second stage, monomers are broken down, and a small amount of ATP is produced.
F. In the third stage, fuel molecules are completely oxidized to CO2 , and no ATP is produced.
Answers
Answer:
C. In the third stage, fuel molecules are completely oxidized to CO2 , and most of the ATP needed for cellular processes is produced.
Explanation:
The three stages in the generation of energy from the oxidation of foodstuffs are given below:
First stage - This stage is the preparation stage and no useful energy is produced in this stage. In this stage, large molecules in food are broken down into smaller units. Proteins are broken down to amino acids, polysaccharides to simple sugars such as glucose, and fats are broken down to glycerol and fatty acids.
Second stage - In this stage, the various small molecules from the first stage are degraded to simple units (mostly acetyl-CoA) that are useful in metabolic activities of the body. Few ATP molecules are generated in this stage.
Third stage - In this final stage, most of the ATP required for cellular processes is produced from the complete oxidation of the acetyl unit of acetyl CoA to CO₂ in the citric acid cycle as well the oxidation of the electron carriers NADH and FADH₂ in oxidative phosphorylation.
For the voltage-gated sodium channel to allow sodium into the cell:_______.
a. the activation and inactivation gates must both be open
b. only the activation gate must be open
c. only the inactivation gate must be open
d. the inactivation gate must be closed shortly before the activation gate opens
e. the activation and inactivation gates must both be closed
Answers
Answer:
The correct option is - (a) the activation and inactivation gates must both be open.
Explanation:
Option (a) is correct because of the following reason -
The axonal membrane is at its natural resting potential until an action potential occurs, and [tex]Na^+[/tex] channels are deactivated and blocked on the extracellular side by their activation gates. The activation gates open in response to an electric current, allowing positively charged [tex]Na^+[/tex] ions to flow into the neuron through the channels. When enough [tex]Na^+[/tex] has penetrated the neuron and the membrane potential has reached a certain level, the [tex]Na^+[/tex] channels inactivate themselves by closing their inactivation gates at the height of the action potential. The inactivation gate can be thought of as a "plug" tethered to the intracellular alpha subunit's domains III and IV. When the inactivation gate is closed, the flow of [tex]Na^+[/tex] through the channel is stopped. As a result, both the activation and inactivation gates must be open to enable sodium ions to enter the cell.
Hence , the correct option is (a).

These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the former relies on manually removing the woods, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the woods but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide
1. Which of the following is the likely reason the weed has remained?
a. The weed needed to be resistant in order to survive, so it became resistant
b. A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
2. Which of the following is likely to happen if that weed stays in place?
a. The trait will spread to nearby weeds
b. The weed will survive long enough to reproduce
c. In time, the herbicide will no longer be effective on that field.
Answers
Answer:
1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )
2) The weed will survive long enough to reproduce ( B )
Explanation:
1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now
2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce
The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation

The human body needs minerals to survive. Without
minerals, the body could not function properly. The minerals
that make up rocks are the same minerals that someone
might eat in a bowl of cereal! The body needs about 80
different types of minerals to function properly. Iron enriches
the blood, salt maintains fluid balance, calcium fortifies the
bones, and fluorine strengthens the teeth. Most vital
minerals can be absorbed into the body from eating plants
and lean meats. However, many food manufacturers add
minerals to their products to make them more desirable to
consumers. Eating a balanced diet can ensure that the
proper amount of these essential minerals is ingested.
Question:
The passage tells us that "many food manufacturers add minerals to their products to make them more desirable to consumers." Do you think that this is a good idea? What are the pros and cons?
Answers
Answer:
You have to put down what you think and not what other people thing
Explanation:
You can simply answer this question yourself by doing research or just thinking if its a good idea
Eating vegetables and lean meats can help the body absorb the majority of essential nutrients. However, many food producers add minerals to their products to increase customer appeal.
What are nutrients?Chemical elements known as nutrients are present in all living things on Earth. They are essential to the survival of all living things, including humans, animals, and plants.
The breakdown of food by nutrients provides energy for living things. They are utilised in every bodily function of an organism.
The majority of vital nutrients can be more easily absorbed by the body when veggies and lean meats are consumed.
To boost consumer appeal, several food companies do, however, add minerals to their products.
Although processing has many advantages, it can also be harmful and reduce the nutritional value of food.
For instance, blanching causes vitamin and mineral leaching losses. Additionally, during processing, milling and extrusion might result in the physical removal of minerals.
Thus, these are some pros and cons of the given scenario.

How would you expect osmosis to affect the water balance in these organisms?
Answers
Answer:
The water balance is the relation or balance between the amount of water entering the organism by intake liquids and food and the total output or loss of water lost from the body by different ways such as the kidneys, lungs, bowels, and skin.
Other than water there is the constant input of electrolytes also occurs into the system. Osmotic pressure and the process of osmosis help in ensuring that optimal concentrations of electrolytes and non-electrolytes are maintained in the cells. The excess water or electrolytes, move out of the cells by the osmosis through the semi-permeable membrane that is the cell membrane here.

What happens in crossing over? Why is it important for sexually reproducing organisms, and what is one of the consequences of errors in crossing over?
Answers
Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.

Yeasts produce more ATP per glucose in their fermentation than do human muscle cells. Choose the correct answer from below.
Answers
Answer:
Only one of the three statement is true; and that is,
(ii.) Different metabolic end products result from the two types of fermentation
Explanation:
Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.
Fermentation is carried out by many organisms including man.
In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.
In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.
From the options provided in the questions, the correct option is:
Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.
