Answer:
A) both the population of rabbits and the population of grasses decreases.
Explanation:
Since there is a larger amount of rabbits, they eat the food (grass) and then the grass amount gets smaller and the rabbits start starving and dying. So both populations would suffer.

4) A hypothetical bacterium swims among human intestinal contents until it finds a
suitable location on the intestinal lining. It adheres to the intestinal lining using a feature
that also protects it from phagocytes, bacteriophages, and dehydration. Fecal matter from

being mixed with water and boiled. The bacterium is not susceptible to the penicillin
family of antibiotics. It contains no plasmids and relatively little peptidoglycan. The cell
also lacks F factors and F plasmids. Which of the following statements about the bacteria
is most probably accurate?
A) The bacterium cannot donate DNA through conjugation with another cell.

A student conducted a controlled experiment to test the affects of tea tree oil on the growth of Trichophyton rubrum, the primary cause of athlete's foot. He inoculated 10 test tubes of broth with the fungus and then added 1 mL of a tea tree oil solution to each.

results that are similar but with slightly different data.
B.

C.

D.

Answers
If the results from the controlled experiment to test the effects of tea tree oil on the growth of Trichophyton rubrum are valid, a similar experiment should produce results that are similar but slightly different data.
What is reproducibility?In science, valid results from experiments must be reproducible.
In other words, the same experiment carried out by different researchers must produce similar results with very little to no variation.
If results from an experiment are not reproducible, such results cannot be valid as far as science is concerned.

What property of water describes the molecule as acting like a tiny magnet?
Answers
Answer:
Intermolecular forces
Water is a dipole and acts like a magnet, with the oxygen end having a negative charge and the hydrogen end has a positive charge. These charged ends can attract other water molecules.
The entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each O−H bond, and therefore, the water molecules are polar in nature and act like little magnets.

A vaccine is a substance that contains all or part of a noninfectious version of a disease-causing organism. When the vaccine is administered to a person, the person's immune system attacks the noninfectious version of the organism and learns to recognize its surface proteins. The next time the immune system comes in contact with the same surface proteins, it has a defense already prepared in order to respond quickly to the invading organism. In this way, a vaccine gives people immunity to the disease-causing organism.
Vaccines can be life-saving, but there have been a few cases of people catching a disease from the administered vaccine.
How might genetically engineered organisms solve this problem?
A.
Disease-causing organisms could be genetically engineered to produce insulin instead of toxins.
B.
Harmless organisms could be genetically engineered to have surface proteins from disease-causing organisms.
C.
Harmless organisms could be genetically engineered to recognize and destroy random cells in the body.
D.
Disease-causing organisms could be genetically engineered to only be harmful to plants.

Answers
We can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.
Why did the water vaporize and then condense?As the water was heated by the electric heater, its internal temperature increased. Once this temperature reached the boiling point of water, the water vaporized or evaporated into a gas. This gas then reached the mirror, where it collected and cooled down, condensing back into a liquid in the form of water droplets.
Therefore, we can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

What happens to a species when the environment undergoes a radical change (e.g. due to climate, food source) and the organisms do not adapt? Explain your answer in not less than 3 sentences. May cite a hypothetical; situation to explain the answer.
Answers
Answer:
If an environment rapidly changes and an organism cannot adapt it will mostly die out. For example, some birds have long, thin beaks that let them reach insects inside trees. If these insects were to disappear for some reason and seeds became the main food source then the birds with long, thin beaks would not be able to eat. Other birds with different adaptations, like short, strong beaks, would be properly adapted to this new environment. So, this second species would replace the first species.
