Answer: Colon cancer

Explanation:

All cancers, but especially colon and rectal cancers, commonly referred to as colorectal cancer (CRC), have hereditary factors that potentially increase one’s risk.

Genetic testing is determine if there is an increased risk of colon cancer. Apolipoprotein E (apoE) plays a major role in the metabolism of bile acids, cholesterol and triglycerides, and has recently been proposed as being involved in the carcinogenic process. Given the potential role of bile acids in colorectal cancer etiology, it is reasonable that colorectal cancer risk might be modified by apoE genotype. The absence of an e3 apoE allele significantly increased the risk of colon cancer especially for individuals above 50years.

What is the difference between the null and alternative hypotheses? Give an example of each. How would you support or fail to su
Gekata [30.6K]

Answer:

Null Hypothesis:

The null hypothesis reflects that there will be no observed effect in our experiment. In a mathematical formulation of the null hypothesis, there will typically be an equal sign. This hypothesis is denoted by H0.

The null hypothesis is what we attempt to find evidence against in our hypothesis test. We hope to obtain a small enough p-value that it is lower than our level of significance alpha and we are justified in rejecting the null hypothesis. If our p-value is greater than alpha, then we fail to reject the null hypothesis.

If the null hypothesis is not rejected, then we must be careful to say what this means. The thinking on this is similar to a legal verdict. Just because a person has been declared "not guilty", it does not mean that he is innocent. In the same way, just because we failed to reject a null hypothesis it does not mean that the statement is true.

For example, we may want to investigate the claim that despite what convention has told us, the mean adult body temperature is not the accepted value of 98.6 degrees Fahrenheit. The null hypothesis for an experiment to investigate this is “The mean adult body temperature for healthy individuals is 98.6 degrees Fahrenheit.” If we fail to reject the null hypothesis, then our working hypothesis remains that the average adult who is healthy has a temperature of 98.6 degrees. We do not prove that this is true.

If we are studying a new treatment, the null hypothesis is that our treatment will not change our subjects in any meaningful way. In other words, the treatment will not produce any effect in our subjects.

Alternative Hypothesis:

The alternative or experimental hypothesis reflects that there will be an observed effect for our experiment. In a mathematical formulation of the alternative hypothesis, there will typically be an inequality, or not equal to symbol. This hypothesis is denoted by either Ha or by H1.

The alternative hypothesis is what we are attempting to demonstrate in an indirect way by the use of our hypothesis test. If the null hypothesis is rejected, then we accept the alternative hypothesis. If the null hypothesis is not rejected, then we do not accept the alternative hypothesis. Going back to the above example of mean human body temperature, the alternative hypothesis is “The average adult human body temperature is not 98.6 degrees Fahrenheit.”

If we are studying a new treatment, then the alternative hypothesis is that our treatment does, in fact, change our subjects in a meaningful and measurable way.

Hope this helps!

Explain the process that takes place in the stroma including and reactants going in nd the products produced from these processe
nikklg [1K]
During the method of photosynthesis, daylight is employed to convert water and dioxide into aldohexose and gas. light-weight reactions convert the energy in daylight into the energy of ATP and NADPH.

a) In the bright daylight, the Calvin cycle happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are accustomed convert molecules of carbonic acid gas into high-energy sugars.

b)In the darkness, the Calvin cycle conjointly happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are used to convert molecules of CO2 into high-energy sugars.

c) <span>There will be a decrease </span>in the products ATP<span> and NADPH if the plants </span>are unbroken within the<span> dark for </span>a protracted<span> time </span>and also the<span> Calvin cycle </span>can't be continued.<span />

Why doesn't air temperature change uniformly with altitude?
babunello [35]
Altitude doesn't change uniformly because the four main layers of the atmosphere have different temperature gradients, creating the thermal structure of the atmosphere.
