Which situation is in equilibrium

Biology
2 answers:
Vikki [24]3 years ago
3 0

Answer: D) The amount of air in a room never changes.

Explanation: Equilibrium is defined as the state in which the concentration of reactants and products is constant or the rate of forward direction is equal to the rate of backward direction.

a) The percentage of nitrogen gas in a room decreases steadily: the amount decreases that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

b) A blade of grass grows taller : the plant gets taller that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

c) The amount of water in a cup decreases as it evaporates: The amount of water is decreasing that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

d) The amount of air in a room never changes: the amount of air does not change as the amount of air leaving the room is same as that of the air entering the room and hence the  reaction is in equilibrium.

Answer:

Option B, a generation

Explanation:

A pedigree is a tree diagram that represents the relationships between different individuals based on certain facts and medical(genetic evolutionary) histories. Basically , the branches of the tree represents the generations which allows the researcher understand how certain genetic characteristics or traits are transmitted with in a family

Such as transmission of any genetic diseases from one generation to the other.  

Hence, option B is correct

When working with radioactive materials you must use radiation detection instruments. Which of the following instruments require
vampirchik [111]

Geiger-Muller tube is instruments requires you test three times the background of the work area.

<u>Explanation</u>:

These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds

Glycolysis
dolphi86 [110]

Answer:

E) can usually make enough ATP for skeletal muscle function

Explanation:

Glycolysis is the main process by which cells obtain energy. During glycolysis, glucose is fully oxidized to obtain ATP, this is the 'fuel' for cellular function. Glycolysis is oxygen dependant, meaning that in order to successfully complete the process, enough oxygen must be available.

There are a few exceptions in which glycolysis is unable to provide enough ATP, an example is strenuous exercise. In this case the speed of oxygen consumption is very high, therefore at some point the oxygen intake is not enough. There are several mechanisms that regulate the production of ATP. In case of strenuous exercise, different process are activated to supply the cell with the necessary energy to keep on functioning.

Among the latter mentioned processes, there is anaerobic production of the oxidation of lactate, that does not require oxygen. Other example is the usage of creatine phosphate to obtain energy. Therefore, muscular cells have many ways of obtaining energy, but this secondary mechanisms are only activated in specific situations.
