Two sister chromatids exchange identical pieces of DNA processes occurs when homologous chromosomes cross over in meiosis I.

Crossing-over can take place when homologous chromosomes couple off during prophase I of meiosis I. Genetic material from homologous chromosomes is exchanged during crossing-over. On each chromosome, new gene combinations are the outcome.

Meiosis II does not include chromosomal pair crossing over or recombination, whereas meiosis I does. This happens during the prophase I of meiosis I, which is divided into five subphases and is lengthy and complex.

The equilibrium potential at 20 degrees Celsius for Na+  is approximately +61 mV, the equilibrium potential for K is approximately -77 mV, and the equilibrium potential for Cl- is approximately -61 mV.

The equilibrium potential for a particular ion is calculated using the Nernst equation:

E = (RT/zF) × ln([ion]out / [ion]in)

Where:

E = equilibrium potential (in mV)

R = gas constant (8.314 J/mol·K)

T = temperature (in Kelvin)

z = charge of the ion (for Na+ = +1, for K+ = +1, for Cl- = -1)

F = Faraday's constant (96,485 C/mol)

[ion]out = concentration of the ion outside the cell

[ion]in = concentration of the ion inside the cell

To find the equilibrium potential for Na+, K, and Cl- at 20 degrees Celsius, we can use the following values:

For NA+ given that [Na+]out = 150 mM, and [Na+]in = 15 mM

E = (8.314 J/mol·K × 293 K) / (1 × 96,485 C/mol) × ln(150 mM / 15 mM)

E = 61.5 mV

For K+ given that [K+]out = 5 mM, and [K+]in = 150 mM

E = (8.314 J/mol·K × 293 K) / (1 × 96,485 C/mol) × ln(5 mM / 150 mM)

E = -77.3 mV

For Cl- given that [Cl-]out = 150 mM, and [Cl-]in = 15 mM

E = (8.314 J/mol·K × 293 K) / (-1 × 96,485 C/mol) × ln(150 mM / 15 mM)

E = -61.5 mV

A higher response of baroreceptors in arterioles is seen with increasing age.

Older adults are more susceptible to orthostatic hypotension because their baroreceptors, which detect changes in blood pressure, respond slowly to these changes. As a result, this student nurse's remark highlights the need for additional instruction.

An example of a mechanoreceptor is a baroreceptor, which enables the autonomic nervous system to communicate information generated from blood pressure. In order to maintain blood pressure within a predetermined, normal range, information is then transferred rapidly in order to modify the total peripheral resistance and cardiac output.

As we age, the baroreceptors become less sensitive. This may help to explain why a lot of elderly persons get orthostatic hypotension, a condition in which standing up from a laying or sitting position causes a drop in blood pressure. Because of this, there is less blood supply to the brain, which results in dizziness.

When a patient has high IgG levels against the virus but low IgM levels, it indicates that the patient has had the infection for some time.

IgG plays a crucial role in the humoral immune response and is the predominant immunoglobulin found in blood, lymph fluid, cerebrospinal fluid, and peritoneal fluid. In addition to albumins, enzymes, various globulins, and a host of other proteins, serum IgG makes up roughly 15% of the total protein in healthy persons.

The first antibody the adaptive immune system produces in response to a foreign antigen is IgM. A 180 kDa heterotetramer of monomeric IgM exists.

IgG antibodies don't become detectable until 10–12 days after the infection, although IgM antibodies might be found several days after the initial infection. A positive test result could indicate that you have some immunity to the virus due to prior exposure.

The Brazelton Neonatal Blank Behavioural Assessment Scale is used to help parents and care providers assess neonates' responsiveness.

The Neonatal Behavioral Assessment Scale (NBAS), developed by Dr. T. Berry Brazelton and his associates, is regarded as the most thorough assessment of infant behavior currently available.

It is best described as a neurobehavioral evaluation scale that was created to capture the newborn infant's contribution to the emergence of the parent-child bond and to explain the newborn's responses to his or her new extrauterine surroundings.

The NBAS is built on the premise that a newborn baby is smart and intricately organized. The NBAS uses 28 behavioral items, each of which is assessed on a nine-point scale, to evaluate the newborn's repertoire of behaviors. It also includes a 20-item, four-point scale assessment of the infant's neurological condition. It is used to study the effect of prematurity, low birthweight, undernutrition, and a variety of pre- and perinatal risk factors, as well as the results of prenatal substance exposure, environmental toxins, temperament, and the behavior of newborns in various cultures, as well as results from prediction studies and research on primate behavior.

Answer:

A Nash equilibrium is a profile of strategies (s1,s2) such that the strategies are best responses to each other, i.e., no player can do strictly better by deviating. This helps us to find the (pure strategy) Nash equilibria.

To start, we find the best response for player 1 for each of the strategies player 2 can play. I will demonstrate this by underlining the best responses:

ABCA1–,10,101–,−10B10–––,01,11,10C−10,110–––,11,1

Player 1 is the row player, player 2 is the column player. If 2 plays column A, then player 1's best response is to play either row A or C, which gives him 1 rather than 0 as payoff. Similarly, the best response to column B is row A, and to column C it is row B.

Now we do the same for player 2 by underlining the best responses of the column player:

ABCA1–,1–0,10–––1–,−10B10–––,01,11,10–––C−10,1–10–––,11,1

So, if player 1 plays row A then player 2 best responds either with column A or column C, giving him 1 rather than 0. We also find the best responses for row B and C.

Now a pure strategy Nash equilibrium is a cell where both payoffs are underlined, i.e., where both strategies are best responses to each other. In the example, the unique pure strategy equilibrium is (A,A). (There may also be mixed strategy equilibria.) In all other cells, at least one player has an incentive to deviate (because it gives him a higher payoff).

EDIT: How to compute mixed strategy equilibria in discrete games?

In a mixed Nash strategy equilibrium, each of the players must be indifferent between any of the pure strategies played with positive probability. If this were not the case, then there is a profitable deviation (play the pure strategy with higher payoff with higher probability).

Consider player 2. He plays column A with probability p, B with probability q, and C with probability 1−p−q. We need to find p,q such that player 1 is indifferent between his pure strategies A,B,C. He is indifferent between row A (left hand side) and row B (right hand side) if p,q are such that

p+10q−10(1−q−p)=q+10(1−p−q).

He is indifferent between B and C if

q+10(1−p−q)=p+q+1−q−p=1.

You just have to solve the first condition for q as function of p, substitute q in the second condition and you have p. Inserting p again in the first gives you q.

Now we do the same with strategies for player 1 such that player 2 is indifferent. Player 1 plays A with probability x, B with probability y and C with probability 1−x−y. The two conditions that follow are

1x+10y−10(1−x−y)=x+10(1−x−y)x+10(1−x−y)=1

Solve this again to find x,y. This is a mixed-strategy equilibrium, because neither player has a profitable deviation. Remember, we constructed the profile (x,y;p,q) such that the other player is indifferent between his pure strategies. So, no matter how the other player unilaterally deviates, his expected payoff will be identical to that in equilibrium (x,y;p,q). In general, depending on the game and solutions x,y,p,q, there may be infinitely many mixed Nash equilibria, or none. The more pure strategies there are, the more tedious it is to compute mixed strategy equilibria, since we solve for N−1 variables for each player (N being the number of pure strategies of the other player).

Moreover, to find all equilibria, if there are more than 2 actions for a player, then every possible combination of actions has to be checked. Here, a player has 3 actions, and a mixed strategy equilibrium could entail mixing over all three or just any two of them. Since such a player would not have to be indifferent regarding the strategy played with probability 0, the equations you have to set up are different. In summary, manually checking for all possible mixed strategy equilibria if at least one player has more than two actions can require a lot of effort.
