The correct answer is (B) glycogenolysis. Glycogenolysis is the process of breaking down glycogen, which is the storage form of glucose in animals, to release glucose into the bloodstream.
Glycogenolysis occurs primarily in the liver and skeletal muscles in response to hormonal signals, such as glucagon and epinephrine, during periods of low blood sugar or increased energy demand. Glycogenolysis involves the enzymatic hydrolysis of glycogen molecules into individual glucose units. These glucose molecules can then be utilized for energy production through glycolysis or released into the bloodstream to maintain blood glucose levels. Glycogenolysis plays a crucial role in regulating blood glucose levels and providing a quick source of energy when needed.

The population of bacteria in a jar grows at a rate proportional to the number of bacteria present at time t. Initially the jar has 20 bacteria. After 8 hours, it is observed that 50 bacteria are present. How many bacteria will there be after 72 hours? You need to set up the differential equation and give an explicit solution.
Answer: Therefore, there will be 15,625 bacteria after 72 hours.
Explanation:
Let N(t) be the number of bacteria at time t. The rate of change of bacteria is proportional to the number of bacteria present, so we have:
dN/dt = kN
where k is the constant of proportionality.
Using the initial condition N(0) = 20, we can solve for k:
N(0) = 20
N(t) = N(0)e^(kt)
50 = 20e^(8k)
ln(50/20) = 8k
k = ln(5/2)/8
Now, we can find N(72):
N(72) = 20e^(72k)
N(72) = 20e^(9ln(5/2))
N(72) = 20(5/2)^9
N(72) = 15625
Therefore, there will be 15,625 bacteria after 72 hours.

The discussion of vacuolation in the human cerebral cortex and its relationship to the interval between death and autopsy and to synapse numbers: an electronmicroscopic study is written in the paragraph below-
Electron micrographs of material acquired up to 69 hours post-mortem from people with no known neurological abnormalities were used to evaluate vacuolation in the human cerebral cortex resulting from swelling of cell processes after death. Vacuolation was shown to considerably rise up to 30-35 hours after death before declining. The number of discernible synapses decreased significantly along with this alteration, which was likely caused by compression brought on by the vacuolation rather than post-mortem disintegration.

Explanation:
Speed is the change of rate in position (distance traveled) by time, it represents how fast or slow something or someone is moving. It is a scalar measure since it does not take into account direction, if direction was taken into account the resulting vectorial measure would be called velocity.
So in order to calculate the speed we would divide the distance moved by the time taken to move:
1500m/3600s = 0.416666 m/s

During production of a drug, all work area surfaces must be disinfected using sterilized disinfectants. Which of the following statements about disinfectants are true? Select all that apply. View Available Hint(s)for Part A Disinfectants destroy all microbes present on a surface. Disinfection can be used to treat work surfaces as well as workers (i.e., washing hands). Disinfection can occur by physical or chemical means. Disinfectants are used to inhibit or destroy pathogens. Endospores and viruses can resist disinfectant treatment.
Answer: The correct options are
--> Disinfectants are used to inhibit or destroy pathogens,
--> Disinfection can occur by physical or chemical means,
--> Endospores and viruses can resist disinfectant treatment.
Explanation:
To prevent infectious diseases from spreading or to sterilise work area surfaces during the production of drugs, chemicals known as disinfectants as used. These are chemicals that kill or inhibit the growth of pathogens. Other chemicals such as antiseptics can also kill and prevent the growth of mainly pathogenic microorganisms. However, disinfectants are stronger chemicals than antiseptics and so are often used on non-living things and surfaces.
Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores (endospores) and viruses, so it is less effective than sterilisation.
There are generally two methods of disinfection:
--> The chemical method: A typical example of a chemical disinfectant is the carbolic acid. It is used for disinfecting lavatories and floors.
--> The physical method: here, physical agents are use to disrupt and damage the pathogenic organisms on work surfaces. Some typical example include: UV irradiation, heat, sunlight exposure, sonic or hydrodynamic pressure and radiation.

What prevents cold air from being circulated to the heated space during the defrost cycle?
During the defrost cycle, cold air is prevented from being circulated to the heated space through a few mechanisms. One key factor is the use of a defrost control board or timer.
This component ensures that the defrost cycle only occurs for a specific duration, allowing the system to quickly and efficiently remove frost from the evaporator coil.
Another important mechanism is the use of a defrost thermostat or sensor. This device monitors the temperature of the evaporator coil and initiates the defrost cycle when it senses that the coil has become too cold and is covered in frost. Once the defrost cycle begins, the thermostat or sensor ensures that the heating elements are activated to melt the frost.
Additionally, during the defrost cycle, the system typically reverses the direction of the refrigerant flow. This helps redirect the cold air away from the heated space and back to the outdoor unit, preventing the circulation of cold air into the heated area.
Overall, these mechanisms work together to prevent cold air from being circulated to the heated space during the defrost cycle, ensuring efficient and effective operation of the heating system.
