What happens when an antigen is introduced into an organism?
A. Myeloma cells are activated.
B. Monoclonal antibodies are produced from plasma cells
C. Polyclonal antibodies are produced from plasma cells.
D. Polyclonal antibodies are produced from somatic cells.
Answer:
B. Monoclonal antibodies are produced from plasma cells
Explanation:
An antigen is a molecule present on the surface of a pathogenic organism and they are capable of generating an immune response by binding to specific antibodies (immunoglobulins) that are secreted by lymphocytes B cells of the immune system. B cells are a type of white blood cell that plays key roles during humoral immunity of the adaptive immune system. When an antigen is introduced into the organism, a specific lineage of B cells proliferate, in a process known as monoclonal expansion.

The traits are:
Tall (T)
Green (G)
Short (t)
Might be yellow (g)
Let's make a Punnet square for it and determine the possible offspring and also their ratio!
See the punnet square.
The same genotypes are denoted by the same color.
So the ration of Genotypes are TTGG (Tall green) : TTGg (Tall green) : TtGg (Tall Green) : Ttgg (Tall yellow) : TTgg (Tall yellow) : ttgg (Small yellow) is 4:4:4:2:1:1
So, the total ratio of Tall green to Tall yellow to Small yellow is 12 : 3 : 1
Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable:
The given question is incomplete, the complete question is:
Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:
Answer:
A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.
A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.
A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.

Which of the following best expresses the concept of natural selection?
A) differential reproductive success based on inherited traits
B) inheritance of acquired characteristics
C) change in response to need
D) a process of constant improvement, leading eventually to perfection
E) survival of the fastest
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
Due to genetic changes and the environmental conditions when the organism adapts itself to the current situation for survival is called natural selection.
Natural selection means that the organism that survived over another have better traits and characteristics for adaptation.
The correct answer is:
Option A. differential reproductive success based on inherited traits.
This can be explained as:
A particular type of trait carried by an organism that is better for adapting to survival than the other organism carrying less favorable trait will have a better chance of survival and their reproductive success will be much higher.Based on the inherited characteristics the natural selection will be based on reproductive success.Differential reproductive success is an analysis in which comparison is done among the organism that survived and those that did not.Comparing their traits and characters can give an idea about the factor affecting the selection.Therefore, differential reproductive success based on inherited traits best expresses natural selection.

Leon was a relatively successful attorney before developing schizophrenia. He has now stopped working and prefers to wander the streets in preparation for an "airlift" of humans by extraterrestrials. He has lost all his property and stays on the streets. His poverty has further aggravated his psychotic symptoms. Leon's story lends credibility to which hypothesis regarding the relationship between social class and schizophrenic symptoms?
A. Social causation hypothesis
B. Milieu hypothesis
C. Downward social drift hypothesis
D. Double bind hypothesis
Answer:
C. Downward social drift hypothesis
Explanation:
In the scenario, being described Leon's story lends credibility to Downward social drift hypothesis. This hypothesis states that there is a clear relationship between mental illness and social class, in which the illness leads the individual to have a downward shift in social class. This is the case with Leon, since he was an upper-class individual until he developed schizophrenia, which ultimately caused him to drop lower and lower in social classes.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.
