Your friend says she does not need a flu shot this year because she got one last year. How do you respond?
A. You are incorrect because the flu virus grows and develops fast enough that your resistance to previous strains may not protect you against more recent strains.”
B. You are incorrect because the flu virus mutates fast enough that your resistance to previous strains may not protect you against more recent strains.”
C. “You are correct because viruses do not grow and develop, so there is only one strain of the flu virus.”
D. You are correct because viruses do not mutate, so there is only one strain of the flu virus.
Answer:
B
Explanation:
The answer to this question is B, because even if she got the shot last year, the flu virus grows and mutates fast enough that she may not be resistant to any new strains.
B. You are incorrect because the flu virus mutates fast enough that your resistance to previous strains may not protect you against more recent strains.
Flu ShotInfluenza vaccines, usually known as flu jabs or flu shots, are antiviral vaccines that protect against influenza virus infection. As the influenza virus evolves rapidly, new vaccine versions are generated twice a year.The flu vaccination trains your body to detect an antigen (protein) on the surface of the virus by using a deactivated or weakened version of the virus.B. It' s not correct to say that one does not need a flu shot this year because she got one last year as the flu virus mutates fast enough that the resistance to previous strains may not protect her against more recent strains.For more information:

Explanation:
Why are there craters on the surface of the moon?(1 point)
Craters formed when acidic water dissolved the surface of the moon.
Craters developed from deep waterspouts in oceans on the moon.
Craters were created when sinkholes formed after rainstorms on the moon.
Craters resulted when meteoroids crashed into the surface of the moon.
Answer:
Craters resulted when meteoroids crashed into the surface of the moon.
Explanation:
Craters resulted when meteoroids crashed into the surface of the moon. The correct option is D.
What are carters?On many solid planets and moons, craters are the most common surface features.
Craters cover both Mercury and the Moon. Numerous circular holes cover this area of the Moon. Each of these craters was formed when an asteroid or comet collided with the Moon's surface.
A crater is a bowl-shaped depression or hollowed-out area caused by a meteorite impact, volcanic activity, or an explosion. Impact craters are craters formed by a meteorite colliding with the Earth.
Scientists can study a planet's history using impact craters even when the records are buried beneath the surface.
Buried material is ejected during impact, while outward pressure pushes the rock at the crater's edge upward, forming a rim.
Thus, the correct option is D.

Is the following sentence true or false? Scientific inquiry is a process with many paths, not a rigid sequence of steps.____________
Answer:
True
Explanation:
Scientific inquiry is a process with many paths, not a rigid sequence of steps. The given statement is true.
The scientific method isn’t as monolithic as it may seem in practice. Sometimes the results of an experiment suggest that a new approach is needed; sometimes, an experiment introduces whole new scientific questions into the picture.
Scientific inquiry goes beyond the development of process competencies such as observation, deduction, classification, forecasting, quantification, inquiry, interpretation, and analysis, all of which must occur simultaneously in order for scientific inquiry to occur.
So, the given statement is true.

Assume that a 100 base pair DNA ladder contains 45 cytosines. How many guanines are there?
Answer:
45 guanines
Explanation:
In a DNA strand, each nitrogen base only pairs with one other specific base.
Adenine pairs with thymine, and cytosine pairs with guanine.
This means that the amount of adenine is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine.
So, if the DNA ladder has 45 cytosines, there will be 45 guanines.

Hope it helps you.....Identify the following observation as qualitative or quantitative
The solution turned blue in color
Hey there! I'm happy to help!
Quantitative data are data that have to with quantities (numbers).
For example, how many inches tall is the plant, what is the pH level of this fluid, what is the temperature of the meat, etc.
Qualitative data are data that can be described or that have a specific quality (qualitative).
For example, are the flowers yellow or green, is the fluid bubbling, does the meat smell burnt, etc.
We see that a solution turning blue doesn't have to do with numbers, so it is not quantitative. It is qualitative because it has to do with the quality (in this case, color) of the solution and not a numerical statistic.

explain movement in fern
Answer:
One of the most typical ways that plants like ferns move is through a process known as phototropism. Essentially, they move and grow towards light .Plants may also move or grow in response to other stimuli, in addition to light. They can grow or move in response to physical touch, in response to a chemical, or toward warmth
How much photosynthesizing material does it take to keep up with a single human’s oxygen needs?
A. 1 medium pool worth of bushes
B. ¼ acre of trees
C. 2 house plants
D. 8 bathtubs of algae
Photosynthesizing material take up 2 house plants for a single human’s oxygen needed. The correct option is C
What is photosynthesis?
Photosynthesis can be defined as the process used by plants and other organisms to convert light energy into chemical energy that through cellular respiration can later be released to fuel the organism's activities. During photosynthesis in green plants light energy is captured and used to convert water, carbon dioxide and minerals into oxygen and energy rich organic compounds.
Therefore during photosynthesizing requirements needed include Sunlight, water and oxygen where two processes occur one light dependent and another which is light independent.

Jorge is studying a pond ecosystem in his neighborhood. The pond is home to a variety of plant and animal species, as well as a stop for birds that migrate through the region.
One summer, heavy rains wash an unusual amount of fertilizer into the pond. Jorge observes the algae population growing rapidly, and quickly algae cover the pond's surface. Several weeks later, many fish and other animals die in the pond. However, within two years, the algae population has returned to its previous size, as have the populations of all the ecosystem members.
Jorge's observations provide the strongest evidence for which of the following conclusions about the pond?
A. The pond ecosystem has very high biodiversity that protects it from invasive species.
B. The pond ecosystem is resilient to changes in many abiotic and biotic factors.
C. The pond ecosystem can withstand only certain levels of algal growth.
D. The pond ecosystem may change over time, but its species will continue living there indefinitely.
Answer:
I think that the answer is C.
Explanation:
If the levels of algae were too high then it would be the reason as to why the fish died. When the algae went back to normal,the fish were able to live there again.
I hope that helps!
Answer:
C.The pond ecosystem can withstand only certain levels of algal growth.
