Answer:
A
Explanation:
B) not all cells have a nucleus. For example, prokaryotes have no nucleus
C)Not all cells have a cell wall.(Animal cells don't)
D) not all cells have mitochondria (Prokaryotes don't)
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.Learn more: https://brainly.com/question/18628083
Which of the following best describes The change in the percent of penicillin-resistant S. Aureus bacteria since 1940
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.

Based on your experimental results, categorize each microbe as preferring isotonic environments, being halotolerant, or as a halophile.
The microbes present in the experiment were:
S. cerevisiae
S. epidermis
A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.
If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:
S. cerevisiae only grows when it is in a 1% solution.S. epidermis only grows when it is in a 1% and 7% solution.
In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

Recombination (crossing over) during prophase I of meiosis occurs when:
Answer:

show that respiratory gaseous exchange in a rabbit occurs at the level of lungs
No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.

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.

After transcription and translation, does the mutation that was in the DNA change the amino acid that the second codon specifies?
Given what we know about genetic mutation, we can confirm that unless the mutation is of the silent type (and sometimes regardless of this), it will in fact change the amino acid that the codon specifies.
Mutations are changes in the DNA sequence of a cell that occur during the replication phase. Cellular mutations can be of many types, such as:
Insertion DeletionSubstitutionInversionand so on, each of which can have varying effects on the amino acid produced.
Most mutations will affect the resulting amino acid in some way. Insertion and deletion tend to be the most harmful mutation types as they alter the way in which the genetic code is processed. Some mutations, however, can be silent, meaning they have no harmful effects due to the fact that the new sequence either encodes the same amino acid or one with a similar enough function. This is possible through mutations like substitution.
Substitution mutations change one nucleotide in a sequence for another. At times, the new sequence will actually encode for the same amino acid as before despite the change. This is one of the only situations in which the amino acid will not be changed. Most often, if a mutation occurs, we can expect the resulting amino acid to change.

the relationship between these species with regards to evolution? Select ALL that apply.

A)
The presence of the owls is a selective pressure for the rodents.
B)
Fewer rodents result in an overpopulation of owls, leading to their
evolution
o
Coevolution is occurring as each population is evolving in response to the
other.
D)
Owls that see camouflaged rodents are more likely to evolve to have
increased variation
E)
Coloration results in poorly or well-adapted rodents while eyesight level
can lead to poor or well-adapted owls.
Answer:A, C, E .
Explanation:
I just did it on USA testprep
A) The presence of the owls is a selective pressure for the rodents.
C) Coevolution is occurring as each population is evolving in response to the other.
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.
