Answer and Explanation:

Some pathogens and pests usually survive and reproduce even when they are exposed to the antibiotics and pesticides repeatedly. These instances show that within the population soe individuals possess the gene for resistance or acquire it through mutation hence survives the chemical. Those that survive transmit this characteristic to their offsprings thus establishing a new population of resistant forms.

Antibiotic resistance in bacteria provides evidence that supports Darwin’s theory of evolution.

<u>Explanation:</u>

Darwin’s theory of evolution mentions about the theory of natural selection by which the nature selects the fittest individuals. It is always the survival of the fittest that takes place in any ecosystem. If there is an external pressure or threat , the organisms that have evolved to overcome this only gets the chance of survival.

Antibiotic resistance that some bacteria show is an example of natural selection. In the initial periods many bacteria would have died out due to the action of antibiotics. In the process of evolution a mutation might have occurred that confers the bacteria resistance to antibiotics.

The process of natural selection allows the bacteria with this mutation offering antibiotic resistance to survive. Since this is a mutation ensuring survival the mutant gene would have been passed over generation producing a species of antibiotic resistant bacteria.

Igoryamba

Answer:

The correct answer is ''All of the choices are correct.''

Explanation:

Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.

Provide at least three reasons why friction is needed.
Oduvanchick [21]

Answer:

Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses.

Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding. In those cases, there is an advantage of having friction.

Quite often uses of frction can be seen from how things would be without friction. Without friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work.
