Answers

Answer 1

Answer:here the symbol M stands for the mass of the object, and V the volume. Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l). A block of wood has a mass of 8 g and occupies a volume of 10 cm3.

Explain the contribution of antigenic determinant in false negative and false positive tests

Answers

Answer:

Contribution of antigenic determinant in false negative -: Popular causes of false-positive ELISA include: flu vaccine administration, presence of HLA-DR antibodies in women with multigravity, presence of rheumatoid factor. Contribution of antigenic determinant in false positive tests -: Positive RPR exam, hypergammaglobulinemia and autoimmune hepatitis (e.g. multiple myeloma).

Explanation:

Much attention has been paid to the specificity and sensitivity of this assay since regular ELISA screening of blood donors for anti-HIV antibodies was implemented. It was found that inadequate coating of the microtitre plates with HIV-antigen could lead to false negative results. It is important that the ELISA test kit manufacturers use control systems that guarantee adequate antigen coating.

Earth is currently in a state of climate change because average global temperatures are slowly but steadily increasing. If this trend continues, what changes would you expect to see in the cicada life cycle? Use information from the article to support your argument

Answers

Answer: Cicadas will emerge from underground earlier in the year. Based on current patterns, they emerge earlier in the south than in the north because it’s warmer in the south, so the soil warms sooner. If global temperatures increase around the world, cicadas will emerge from the ground in all areas earlier than expected.

Explanation:

In neuroscience, depolarization is an "all or nothing" response; what does that
mean?
The neuron's intracellular charge must get more negative to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire

The neuron will either accept all signals, or none of the signals received. If the
neuron is ready to receive signals, then it automatically depolarizes and sends the
signals to the next neuron.

The neuron's intracellular charge must get more positive to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire

The neuron decides how much of the electochemical signals to send to the next
neuron; all or nothing

Answers

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

Runners only have enough stored ATP in their muscle cells to run for about five seconds. Which answer correctly explains how the runner's body adjusts to the longer distance, for example, a marathon (42.1 km)?

Answers

Answer Options:

A: The runner's body will convert stored fat molecules into energy.

B: The runner's body will create the needed energy by breaking down proteins.

C: The runner's body will supply the needed energy by producing starch.

D: The runner's body will produce the energy by activating the Golgi apparatus.

Answer:

A: The runner's body will convert stored fat molecules into energy.

Explanation:

When the body needs energy to power cells, it uses ATP. ATP is generated by cellular respiration, which involves the breakdown of (usually) sugars by aerobic respiration.

If you exercise for a longer period such as during long distance running, your body will use more fat and less glucose in an attempt to conserve the limited glucose stores in case exercise intensity increases and oxygen availability is is reduced.

 

The runner's body will convert stored fat molecules into energy.

Which of the following is true of the Celsius scale A.) 212° is the boiling point of water b.) 0° is absolute zero c.) 0 degrees is the freezing point of water or D .) 32° is the freezing point of water

Answers

Answer:

The correct answer is C., or ¨0 degrees is the freezing point of water¨.

0 degrees is the freezing point of water is true about the Celsius Scale. Therefore, option (C) is correct.

Water freezes at "zero degrees" on the Celsius scale. Under ordinary climatic conditions, water's freezing point is 0 degrees Celsius and its boiling point is 100 degrees Celsius. Many countries use this scale to measure temperature.

However, the Fahrenheit scale, used mostly in the US, has different freezing and boiling points for water. Water freezes at 32 degrees Fahrenheit and boils at 212. Therefore, option (C) 0 degrees is the freezing point of water is correct.

Which of the following statements about the action potentials in contractile myocardial cells (cardiac muscle) is INCORRECT? Compared to skeletal muscle cells, contractile myocardial cells have a lower (more negative) resting membrane potential. Action potentials are propagated between adjacent cardiomyocytes through gap junctions. The duration of an action potential in a contractile myocardial cell is greater than the duration of an action potential in a typical neuron. During the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium.

Answers

Answer: During the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium.

Explanation:

Apart from the fact that contractile cells conduct impulses, it also helps in contractions which are needed for pumping of blood. It should also be noted that the myocardial conducting cells serves as the heart's conduction system. They also have a lower resting membrane potential.

Of the options given, the answer is the last option i.e. during the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium. This is wrong.

Repolarization occurs due to a rise in the permeability of potassium and during repolarization, the calcium channels close.

Answer:

It should be A. If the pesticide is released, then they die, and the consumers of the grasshopper (snake) dies due to no grasshoppers, then the animal that consumes the other animal (hawk eats snake) that eats the grasshopper will die because there aren't enough of that animal for it to eat. the only thing that lives is the grass.

The Wright brothers used a wind tunnel to test there model planes. The reason it has limitations is there is no wind is space because there is no gravity which means there is no particles that make up weather and wind.
