This class of studies is generally used in developmental psychology.
Which nerve is responsible for weakness in climbing stairs or jumping?
A. Tibial
B. Superior gluteal
C. Inferior gluteal
D. Obturator
E. Femoral
Answer:
C. Inferior gluteal
Explanation:
The inferior gluteal nerve has a rich concentration in the gluteus maximus muscle. This muscle is located in the hip region. These nerves are primarily responsible for the ability of the gluteus maximus to move and performs some functions during motion.
An example of such function involves the extension of the hip to the thigh in movements such as climbing stairs, hiking, squatting etc.

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.

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.
Which event might occur if the populations of producers in an ecosystem became unstable? A) The direction of energy in the food web would change directions and flow toward the producers. B) Decomposers would become the primary energy source. C) The number of primary consumers would decrease dramatically. D) The energy flow into the food web would decrease or increase along with changing populations of producers. THANK YOU !!! :-)
Answer:
If the populationsl of producers in an ecosystem became unstable the energy flow into the food web would decrease or increase along with changing populations of producers.
Answer:
Answer: option D.
Explanation:
Hey, there!
Reason: The reason is, when the number of producers are unstable, the flow to enegry from abiotic components to biotic components will be destructed. There will not be proper flow of enegry in whole ecosystem, which usally changes the flow of enegry as per the number of producers.

A mutation occurs, and cytosine is replaced with adenine. What impact do you think this will have on the DNA structure?
Adenine is larger than Cytosine base pair which make it unable to base pair properly with the guanine on the opposing strand. This will cause the DNA to bulge.
What is Mutation?Mutation refers to a sudden change. It is a change in the nucleic acid sequence of an organism's genome. This results in changes to the cell's DNA sequence that can be caused by mistakes during cell division, or by exposure to DNA-damaging agents in the environment.
There are two major types of mutations which are:-
1. Germline mutations
This type of mutation occur in gametes
2. Somatic mutations
This type of mutation occur in other cells of the body.
There are also some types of mutations that are found. They are
1. Base substitutions
2. Deletions
3. Insertions.
Thus, Adenine is larger than Cytosine base pair which make it unable to base pair properly with the guanine on the opposing strand. This will cause the DNA to bulge.

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

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 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.

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.

g What are the three basic assumptions of Darwinian evolution? Group of answer choices Presence of phenotypic variation, some phenotypic variation due to genetic variation, the given trait has an impact on fitness Presence of phenotypic variation, environmental variation, the given trait has no impact on fitness Presence of phenotypic variation, environmental heritability, the given trait has an impact on fitness Presence of phenotypic variation, trait present in only the mitochondrial DNA, the given trait has an impact on fitness
Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.
