Answer:
G. The star is cooler than a blue star
Explanation:
If the star the astronomer observed is similar in color and size to our sun, then it's impossible for it to be a white dwarf star because they are white and much smaller, while the star the astronomer observed had to have been some shade of yellow or orange and is similar in size to our sun.
A blue star is hotter than our sun by approximately 5000 kelvin. If the star observed is similar in color to our sun then we know that it hasn't reached a temperature hot enough to surpass a blue star, for colors of star change depending on temperature.
Our sun is not as bright as a red giant star. If the observed star was similar in color and size to the sun, then it couldn't have been as bright either.
There is no evidence that supports the star is farther away from other stars in the solar system.
Therefore, the option that makes the most sense is option G.

The greatest health risk from food today is contamination via Multiple Choice parasites. prions. viruses and bacteria. fungi.
We can confirm that the greatest health risk from food today is contamination via viruses and bacteria.
Why are we at risk of contamination from these sources?Viruses and bacteria are the greatest threat to humans at the current time, as far as food contamination. These organisms are microscopic and thrive in many of the most common human foods. While parasitic infections are rare and fungi can often be spotted on food, viruses and bacteria are nearly impossible to notice and much more common in food.
Therefore, we can confirm that the greatest health risk from food today is contamination via viruses and bacteria.

Clausen and colleagues proposed two hypotheses to explain this variation within a species: (1) There are genetic differences between populations of plants found at different elevations. (2) The species has developmental flexibility and can assume tall or short growth forms, depending on local abiotic factors. If you had seeds from yarrow plants found at low and high elevations, what experiments would you perform to test these hypotheses
A possible experiment to test these hypotheses would be to plant the seeds at different elevations and verify the differences in these.
What is an experiment?This is a scientific procedure that aims at testing hypotheses or potential explanation for a phenomenon.
What should be considered when designing a hypothesis?Make sure the factors tested can be measured.Control variables.Design an experiment that can test the hypothesis.What is the best experiment?There are two possible experiments:

Why is daily muscle strengthening activity not recommended?.
Daily muscle training is not recommended as it will lead to injury and fatigue.
Why does daily training lead to injury?Muscle training is an intense activity for your muscles. Training every day can cause injuries such as muscle tears or tendonitis from overusing the muscle in an intense manner for too long. For this reason, it is best to allow the muscle to rest at least one day before attempting to train again or undergoing intense activity.
Therefore, we can confirm that daily muscle training is not recommended as it will lead to injury and fatigue due to overusing the muscle in an intense manner.

According to Ernest Hilgard, hypnosis is the result of the effects of a hidden observer in the unconscious. Hypnosis is a state of loss of voluntary functions in the conscious state.
What do you mean by Hypnosis?Hypnosis may be defined as a state that corresponds to sleep but is caused by a person whose directions are readily accepted by the subject.
The hypnotic individual lacks the power of voluntary actions and is positively responsive to directions, suggestions, and reccomendation. Although, it is a state of consciousness.

What occurs at the ATP synthase?
Answer:
Phosphorylation of ADP, i.e. ATP synthesis
Explanation:
Long answer: The protons from the inter-membrane space flow into the matrix of the mitochondrion through ATP synthase. As they are moving down the concentration gradient, energy is released and this is used by ATP synthase to phosphorylate ADP, i.e. add inorganic phosphate to ADP in order to create ATP.
The dna polymerase extends the primers into a new dna strand by.
Answer:
adding nucleotides one by one
Explanation:
A typical primer is about five to ten nucleotides long. The primer primes DNA synthesis, i.e., gets it started. Once the RNA primer is in place, DNA polymerase "extends" it, adding nucleotides one by one to make a new DNA strand that's complementary to the template strand.
A person dies from sudden cardiac arrest every _______ seconds.
Answer:
315.36 seconds
Explanation:
A person dies from sudden cardiac arrest every 315 seconds. This is a heart condition which results into unexpected stoppage of heart beats.
What is Cardiac arrest?Cardiac arrest is a condition in which the heart suddenly and unexpectedly stops beating. It is a medical emergency which without any immediate medical intervention, could result in sudden cardiac death of person within minutes. Cardiopulmonary resuscitation (CPR) is one method which could save the patient and possibly defibrillation are the needed treatments until further treatment can be provided to the patient. Cardiac arrest results in a rapid loss of consciousness in a person, and breathing may be abnormal or absent in this case.
Some of the most common causes of cardiac arrest involve an already underlying heart problem like coronary artery disease which decreases the amount of oxygenated blood supplying the heart muscles.

What is evolution?Evolution refers to a series if gradual and cumulative and transferrable changes which occur in organisms that resulted in the formation of new species from existing species.
Factors affecting evolution include;
gene flow,the rate of mutation andnatural selection.When there is less gene flow between populations as well as higher rate of mutation, evolution of species will be most like likely.
