Explanation:
Anorexic individuals have trouble maintaining normal body temperature because of?
Anorexic individuals have trouble maintaining normal body temperature because of the loss of body fat as insulation and lack of appropriate weight-loss strategy.
Anorexia nervosa patients (ANs) have significantly lower core temperatures (T-core) compared to healthy controls (HCs). This reduced temperature represents a reset T-core that needs to be maintained.
The development of anorexia nervosa (AN) is attributed to psycho-social causes. Anorexic individuals have night sweats because the low body weight interrupts the body's normal hormonal functions, which may halt ovulation. Excessive exercise and stress can cause similar problems.
It also effects the body if a person with anorexia becomes severely malnourished, every organ in the body can be damaged, including the brain, heart and kidneys. This damage may not be fully reversible, even when the anorexia is under control.

Shaun has pneumonia. Pneumonia is a lung infection that causes the alveoli to accumulate pus and/or fluid. How does this effect the diffusion of oxygen into the blood
In pneumonia, the accumulation of pus and/or fluid will thicken the respiratory membrane and slow down the diffusion rate. This would decrease the amount of oxygen taken up by the blood.
How does pneumonia affect diffusion in the alveoli?Pneumonia is caused by an infection, and a wide variety of microbes can infect the lungs. Pneumonia is typically brought on by bacteria or viruses, but it can also be brought on by fungus and other organisms. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing.
In alveoli, blood is given oxygen and carbon dioxide is expelled. Pneumonia causes the alveoli in one or both lungs to swell with fluid and pus (exudate), obstructing normal gas exchange. Consolidation and collapse of the lung is another name for this. Diffusion is the method used for gaseous exchange at the alveoli.

What is the most likely effect of a mutation that changes the repeat sequence found in terc from 3’-cccaau-5’ to 3’-ucaggacg-5’?.
If the repeat sequence of telomere changes from 3’-cccaau-5’ to 3’-ucaggacg-5’ due to any mutation in TERC gene then the telomerase enzyme will be unable to attach to the 3' overhung of the telomere sequence and cannot elongate new DNA strand [telomeric part]. As a result, the telomeres of chromosomes cannot be elongated and the entire chromosome or the cell will be lost after a few rounds of division.
Telomere: They are short repeating sequences found at the end of the chromosome whose function is to save the chromosomes from degradation. But after each round of replication, the length of the telomeres becomes shorter than the previous and after a certain number of cell divisions, the telomeres become so short that they trigger the cell to stop dividing or to self-destruct (undergo apoptosis).
So, to prevent the shortening of telomeres, the TERC gene codes a telomerase enzyme which is a type of reverse transcriptase made up of two components: an RNA part that is complementary to the repeated telomeric sequence and a protein part that can add the nucleotides to the 3' end of the telomere.
After every cell division, the telomerase enzyme gets attached to the 3' end of the shortened telomere end and synthesizes the complementary DNA to the RNA part of the enzyme until the length of the telomere is restored again.

Which current is produced inresponse to a hyperpolarizing stimulus in a giant axon of a squid?
The giant axon of a squid, shows that hyperpolarizing stimulus is followed by transient inward capacitive current and lasting outward capacitive current.
Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.
Hyperpolarization can be caused, for instance, by opening channels that allow positive ions to move out of the cell (or negative ions to move in).
The hyperpolarization-activated current is an inward current activated by hyperpolarization from the resting potential and is an important modulator of action potential firing frequency in many excitable cells.

It may be easy for two neighbors to agree to drain a meadow, which they possess in common, to grow crops. However, when the meadow is much larger and reaches thousands of people, the solution is more difficult because of the free rider problem.
What is the free-rider problem:
The free-rider problem arises when people enjoy the benefits of a common resource without making any contributions towards it, resulting in market failure. Market failure refers to when a good or service gets distributed inefficiently in a market.
When only two neighbors share a meadow, they can easily hold each other accountable for draining the meadow on time. However, when the meadow can be accessed by thousands of people, it is difficult to hold one person accountable for draining it. Everyone will want to use the meadow to grow their crops. However, none will be willing to take the responsibility of draining it since they know that if they wait for someone else to drain the meadow, they can benefit from it without having to do any work themselves.

What do having the measles and being vaccinated against the measles have in common?
They are both forms of active immunity.
What is active immunity?When our own immune system defends us against a pathogen, this is known as active immunity. Our immune system develops active immunity when exposed to a potential disease-causing substance (i.e., pathogen). Active immunity is crucial since it not only "fights off" these pathogens but also lasts a very long period in the form of immunologic memory.
B and T lymphocytes with the ability to recognize a particular pathogen make up immunologic memory. These cells circulate at low levels in human bodies, but if they become "activated" by encountering the pathogen while traveling, they rapidly begin to multiply and send signals to other immune system components to do the same. There are two reasons memory cells are important. They first help our immune systems react swiftly. The immune response is prepared the moment the infection is contacted since they are secondly pathogen-specific.
