Answer:
The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.
Explanation:
Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.
In scientific reasoning, a hypothesis is made before any applicable analysis has been done. A theory, on the opposite hand, is supported by evidence: it is a principle shaped as an effort to clarify things that have already been supported by knowledge<span>.
</span>For example: “It's bright outside.”
Hypothesis: A projected clarification for a development created as a place to begin for additional investigation.
Theory: A well-substantiated rationalization nonheritable through the methodology and repeatedly tested and confirmed through observation and experimentation
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:
Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.
Answer:
The correct answer is :
Independent variable: study music.
Dependent variable: test performance.
Explanation:
Independent variable in a experiment is a variable or a factor that is manipulated or changed in a particular experiment to see its the effect on dependent variable of this change. In this case classical music is variable as it is manipulated to see if it has any effect on studying.
Dependent variable is a variable which is measured in experiment to find the result and affected by the independent variable. In this case testing the performance of subject is dependent variable as it is being measured and affected by classical music.
Thus, the correct answer is: Independent variable: study music.
Dependent variable: test performance.
Question:
To code for the operating microscope, what verbiage are you looking for in the medical record?
(a)loupes were donned for magnification
(b)microdissection may be necessary
(c)due to the intricate dissection under magnification
(d)the operating microscope was steriley draped and brought into the surgical feild
<u>Answer</u>:
Option D: The operating microscope being sterilely draped and brought into the surgical field.
<u>Explanation:</u>
The loupe present is for the single vision magnifying glass, that can be frequently seen with the gold smith and with the watchmakers. The operating microscope are the binocular microscope through which small intricate parts can be observed during repairing of the watches etc. It is used in the surgery for observing the blood vessels as well as the nerves. This instrument can never be sterilized so after the use, it should be properly wrapped sterilely and kept inside the operation room.
