1. Gravity also increases

2. Gravitational attraction also decreases

3. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Which of the following best describes The change in the percent of penicillin-resistant S. Aureus bacteria since 1940

Answers

According to the information provided in the graph it can be inferred that the percent of resistant S. aureus doubled from 1950 to 1960.

The graph shows the evolution of the resistance of the Streptococcus aureus bacteria to penicillin from 1940 to 2010. The percentage of resistance evolved as follows:

1940 - 0% 1950 - 40% 1960 - 80% 1970 - 83% 1980 - 88% 1990 - 90% 2000 - 97% 2010 - 100%

According to this information, it can be inferred that the correct answer is option B because the percentage of resistance of S. aureus doubled from 1950 (40%) to 1960 (80%). Additionally, the other options are not because:

A. Between 1980 and 2010, resistance growth was lower than in previous years. C. Resistance peaked in 2010 (100%). D. Loading capacity was reached in 2010.

Note: This question is incomplete because the graph, options and some information is missing. Here is the missing information:

Pneumonia is a lung infection that can be caused by a species of bacteria, Streptococcus aureus. The antibiotic penicillin has been used historically to treat bacterial pneumonia. In recent years, doctors have observed that penicillin is less effective as treatment for pneumonia.

Doctors collected data about the percent of S. aureus bacteria that were resistant to penicillin. The graph shows the percent of penicillin-resistant S. aureus from 1940 to 2010 in one hospital.

A. The percent of resistant S. aureus grew exponentially from 1980 to 2010.

B. The percent of resistant S. aureus doubled from 1950 to 1960.

C. The percent of resistant S. aureus reached its peak in 1960.

D. The S. aureus population reached its carrying capacity by 1990.

A) all cells contain DNA, and DNA is all composed of adenine, thymine, guanine, and cytosine.

Living things are those organisms that have life and they possess the basic characteristics that enable them to be termed as living. This include growth, reproduction, irritability etc.

The property listed in the options shared by cells of all living things is the cell contain DNA composed of adenine, thymine, guanine and cytosine.

All living things contain the genetic material (DNA) that carry the needed information essential for their cells to function. Although some living things do not have a membrane bound nucleus eg prokaryotic cells. Many differences therefore exists that differentiates the living things from one another bringing them into groups.

Explanation:..

Answer: B

Explanation: The International Space Station ISS (assume that the weight of the ISS, if it were on the surface of the earth, is approximately 990,000 pounds) orbits the earth at an altitude of approximately 250 miles above the surface of the earth. Assuming a circular orbit, what is the attractive force that the earth exerts to keep it in orbit? An object's mass does not change from place to place, but an object's weight does change because the gravitational acceleration ge depends on the square of the distance from the center of the Earth. Let's do a calculation and determine the weight of the Space Shuttle in low Earth orbit. On the ground, the orbiter weighs about 250,000 pounds.

Memory is___; therefore, ___.

1) an exact replica of an event; we should be confident about the accuracy of people's memories

2) like a video cassette recorder; we should wonder about the accuracy of people's memories

3) reproductive; we should wonder about the accuracy of people's memories

4) reconstructive; we should wonder about the accuracy of people's memories

5) reconstructive; we should be confident about the accuracy of people's memories

Answers

Memory is reconstructive and we should therefore wonder about the accuracy of people's memories.

Recalling an event via memory has the tendency to be influenced by other cognitive processes, including perception, beliefs, ideologies, imaginations, etc. This phenomenon, known as reconstructive memory, is one of the key theories of memory recall.

This is one of the reasons 2 people who witnessed an event will have different reports for the same event. Thus, the reconstructive memory theory leaves no other option but to wonder about the accuracy of people's memories.

What is predator?

A predator is an organism that hunts, kills, and feeds on another organism known as the prey. Predation is a biological interaction between two species, where one species benefits by consuming the other species, and the other species is harmed or killed.

These two statements correctly evaluate the relationship between the predator and prey species in terms of evolution. The presence of owls as predators creates a selective pressure for rodents, where those with traits that allow them to escape predation are more likely to survive and pass on their genes.

This leads to the evolution of better-adapted traits in the rodent population over time. The interaction between owls and rodents can also be considered an example of coevolution, as changes in one population can drive changes in the other population, leading to a reciprocal evolutionary response.

Overall, the relationship between predator and prey species is complex and constantly evolving, with each population influencing the other's evolution over time.

Describe solution concentration outside the cell in terms of hypotonic, hypertonic and isotonic.

Answers

Answer:

see below

Explanation:

Hypotonic solution is a very dilute solution to the more concentrated solution. Hypo means under . A solution with a lower concentration of solutes than the cytoplasm of a cell, that solution is hypotonic to the cytoplasm. The cell expands as water moves in.

Hypertonic solution is a more concentrated solution to cytoplasm. Hyper means above. A hypertonic solution has higher concentration of solutes than the cytoplasm of the cell. The cell shrinks as its cytoplasm loses water.

Isotonic solution is when two solutions of equal concentration are separated by a semi permeable. Iso means equal. Therefore, in isotonic solutions, water movement out of a cell balances the water movement into it. Cells in the body are usually surrounded by a fluid. The cytoplasm in the cell is usually isotonic to the fluid outside the cell. Hence, no net gain or loss of water by cells.

So, basically, if a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.

What will be the total number of thymines if a DNA molecule has a total of 1500nucleotides?

The DNA molecules would be given and it have 450 thymines if the DNA molecule has the total of 1500 nucleotides and the DNA molecule also have been known as the deoxyribonucleic acid has been made up of the double helix. The DNA molecule with the total of 1500 nucleotides would contain 750 cytosine and Thymines and 750 guanines and adenine.

Hence, we can have the expression:

C + T = 750

If there are 300 cytosines, hence;

300 + T = 750

T = 750 - 300

T = 450

A nucleotide has the monomer constituting DNA or RNA biopolymer molecules and the double-stranded DNA molecule posseses two strands of DNA made up of the nucleotides.

Therefore, If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.
