Answer:
Stomach Flu
Explanation:
Stomach flu—or gastroenteritis—is an infection of the stomach and upper part of the small intestine. Common symptoms are diarrhea, vomiting, stomach pain, and cramps. Rotavirus and norovirus, which affect millions of people every year, are often the cause. Gastroenteritis often clears up on its own, but you lose fluids through diarrhea and vomiting. Prevent dehydration by drinking water and electrolyte drinks.

have a difficulty of keeping koala bears alive because Koala bears are
susceptible to viral infections. There is a virus that is present to Koalas
which is called the Koala retrovirus. Koala retrovirus makes a Koala bear more
susceptible to infections and even cancer. </span>
Answer:
FALSE
Explanation:
Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.
Answer:
Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.
Explanation:
As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.
Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.
In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.

A type of a balanced stretch involves targeting a specific muscle group. When stretching, a person should be aware of the agonist and antagonist muscles being stretched in able to create a balance between the joints where the muscles are attached. Stretching is an important phase in the exercise cycle and should not be missed as this prevents injuries in the joints and increases the blood flow into the muscles that were used during the activity. Stretching also contributes to lessening the lactic acid build up that happens during physical activity.</span>
