The relative concentration of each in the plasma membrane is partly regulated by the:_______
Answer:
ion channels
Explanation:
The plasma membrane plays a critical role in regulating and maintaining ionic potential inside the cell, relative to ionic concentration present outside the cell. The ion channels are specific, in that they only recognize and allow particular ions to pass through and block the rest. Their opening and closing depends on the ionic potential during that time period.

As the adrenal gland releases glucocorticoids, which of the following effects may be observed? a) Increased blood levels of amino acids
b) Decreased blood pressure and volume
c) Decrease in immune system function
d) Lipid breakdown in the liver will increase
e) Increased water absorption in the kidney
f) Increased blood glucose levels
Answer:
The correct option is F) Increased blood glucose levels
Explanation:
The release of glucocorticoids into the body is part of the body's chemical process for managing stress and ultimately prepares the body for fight or flight.
The body anticipates that it may consume additional fuel/energy during elevated stress levels, it therefore through the adrenal cortex which is situated above the kidneys, sends glucocorticoids into the body.
The glucocorticoids trigger the body's metabolism with regard to breaking down stored fuel in order to produce the required energy that it needs.

In a fluorescence recovery after photobleaching (FRAP) experiment, a fluorescently tagged membrane protein, A, shows very little recovery of fluorescence ten minutes after photobleaching, while membrane protein B shows a rapid increase in fluorescence after bleaching, recovering nearly 80% of its original fluorescent signal by ten minutes. Based on this information, which of the following statements can be made?
A. Proteins A and B interact with each other in a complex
B. Protein A is easily denatured,
C. Protein Bis diffusing in a more fluid membrane.
D. Protein Ahas faster mobility in the membrane.
Answer:
The correct answer is option C. Protein Bis diffusing in a more fluid membrane.
Explanation:
Fluorescence recovery after photobleaching or FRAP is a technique used to examine the portability of fluorescent particles with the help of fluorescence microscopy that have been utilized since the mid-70s to evaluate the dispersion or movements of molecules in the cell membranes of the cell.
Fluorescence Recovery After Photobleaching (FRAP) is a strategy for deciding the energy of dispersion in living cells (typically) utilizing fluorescence microscopy.
In the given experiment:
The diffusion coefficient of GFP vary, based on the localization of the protein
Protein B is freely diffusing, due to which recovery is very high compared to protein A.
Protein which is less diffusing shows a slower and less rate of recovery.

How does exponential growth differ from logistic growth? R‐selected species have exponential growth rates, whereas K‐selected species always experience logistic growth. Exponential growth occurs when the population is at its biotic potential, whereas logistic growth is limited by the carrying capacity of the environment. Exponential growth is expressed as doubling time, whereas logistic growth is expressed as a percentage change. Exponential growth occurs when a population is very large, whereas logistic growth occurs when a population is at its minimum viable number. Exponential growth results in a J‐shaped curve, whereas logistic growth results in an S‐shaped curve.
Answer:
Exponential growth occurs when the population is at its biotic potential, whereas logistic growth is limited by the carrying capacity of the environment.
Explanation:
A population that exhibits a logistic growth model, depends on density, the natality and mortality rate depends on the population size, which means that there is no independence between population growth and population density.When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.
If the population size, N, is inferior to K (N<K) the population can still grow. When N approximates to K, the population´s growth speed decreases. When N=K, the population reaches equilibrium, and when N is superior to K (N>K) the population must decrease in size because there are not enough resources to maintain that size.
The sigmoid curve represents the logistic growth model. At the beginning population grow slowly. In the exposed example this occurred when the small group of 10 foxes moved to the new environment, starting a new population. In the second stage, the population size increases rapidly. Probably this happened when foxes reached a number of 40 individuals. And finally, slow and gradually, the population reaches the equilibrium point, K, which depends on resource availability. This point belongs to the stage where food starts to become harder to find, and much of the living space is occupied.
A population that exhibits an exponential growth model increases in proportion to its size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.This model is based on unlimited resource availability which means that there is no effect depending on density. There is no competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita and it is proportional to the population size.

A two-year-old weighing 25.2 lb is admitted to the hospital with fever and diarrhea. Normally the child weighs 29.6 lb. How much fluid (in liters) needs to be replaced in the child's system?a. 1Lb. 1.75 Lc. 2 Ld. 4.4 L
Answer: C.) 2L
Explanation:
Given the question :
A two-year-old weighing 25.2 lb is admitted to the hospital with fever and diarrhea. Normally the child weighs 29.6 lb. How much fluid (in liters) needs to be replaced in the child's system?
Normal body weight if the baby = 29.6lb (pounds)
Weight of baby die to fever and diarrhea = 25.2lb(pounds)
Weight loss due to diarrhea and fever :
(29.6 - 25.2)lb = 4.4 lb
Amount of fluid needed to be replaced in litres = weight loss due to sickness
Then we need to convert 4.4lbs to Litre (L)
1 pound (lb) = 0.45359 liter (l)
4.4 lb = (4.4 * 0.45359) L
= 1.995796 L
= 2L
Which of them is important in endurance race physical strength or emotional strength?
Answer:
Both
Explanation:
Endurance deals with how long you can do something that puts a physical strain on your body and not necessarily how much strain at once. That being said both physical strength and emotional strength play a big role in this. Physical strength is needed to be able to exert yourself and accomplish the initial task in the first place. While emotional strength is also needed in order to not give up and persevere as long as possible. Without will power (emotional strength) you will give up as soon as you are given the opportunity.
Meter is called a standard unit.Give reason.
Answer:
The meter is not called a fundamental unit, except informally by some people. In the International System of units (SI), the meter is one of seven base units. Base units can be defined in terms that do not depend on no units beyond other base units or natural constants (e.g., the speed of light). Using no more than those seven base units, other units can be defined and those are called derived units. No factors or coefficients other than one are used to show how they relate to each other

How does the injection of insulin affect the signal transduction pathway of type 1 diabetics?
a. Injected insulin prevents the glucose from binding to cellular protein receptor.
b. Insulin acts as a secondary messenger that cascades the message to allow glucose into the cell.
c. Insulin is absorbed into the cytoplasm and binds with the transcription factor to make it active.
d. Protein receptors on the cell bond to the insulin, which allows glucose to enter the cell.
Answer:
The correct answer is D.
Explanation:
To act on target cells, insulin binds to a specialized protein that is located on the membrane of your target cells: the insulin receptor. When insulin binds to the receptor, it activates a cascade of signals within the cell (a process called signal transduction), which is essential for insulin to have an effect on its target tissues. Insulin increases the entry of glucose into cells and causes the number of certain proteins specialized in glucose transport to increase in the membrane of their target cells, such as adipocytes (adipose tissue cells) and skeletal muscle cells.
Answer:
The correct answer is B, b. Insulin acts as a secondary messenger that cascades the message to allow glucose into the cell.

a medical reasearcher is testing a new experimental drug for a headache patients Group A consists of 100 participants who are given the new exprimental drug group B consists of 100 participants who are given a placebo or fake pill. Neither group knows which treatment they received Which is the control group?
Answer:
Group B... (the Placebo)
Explanation:
I say group B because the medical reasearchers are using group B to see the outcome and effects of the experimtal drug that they gave group A. So if in the end group A (given the experimental drug) has a better response to the headache after taking the pill then group B (given a fake drug) the medical reasearcher will know the effectiveness of the new drug.
