1. C. Why a handle of a metal spoon also gets hot when placed on a steamy soup.
2. D. It determines the hotness or coldness of an object.
3. D. Energy transferred due to temperature differences.
4. C. The object is a thermal insulator.
Explanation:
Convection is the transfer of heat energy through the movement of a liquid or gas from one place to another. If we place a metal object at a distance from the hot body so the fumes that comes out increase the temperature of the metal that is present on the hot body. Temperature determines the hotness or coldness of an object not the heat. The heat energy transferred from one body to another due to difference in temperature of both objects. Insulator are those materials which no ability to transfer heat energy from one place to another.

How would you expect osmosis to affect the water balance in these organisms?
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.
Study the following statements, which compare the method of fermentation preferred by yeasts to they type of fermentation that may occur in human muscle cells. i. Yeasts produce CO2 during fermentation, but human muscle cells do not. ii. Different metabolic end products result from the two types of fermentation. iii. Yeasts produce more ATP per glucose in their fermentation than do human muscle cells. Choose the correct answer from below.
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.

When a patient experiences respiratory alkalosis, the
physiological compensation will be what?
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.
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
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).
