Which of the following statements about symbiotic relationships is true?
In mutualism, neither organism benefits.
At least one organism benefits from commensalism.
In parasitism, both organisms are harmed.
Both organisms benefit from commensalism.
Answer:
At least one organism benefits from commensalism.
Explanation:
The symbiotic relationship of commensalism is when one organism benefits and the other organism receives neither benefit nor harm.
So, this statement is true, because at least one organism has to benefit from the relationship, while the other will not be harmed or helped.

What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?
Answer:
Please mark as brainliest!!!
Explanation:
Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.
It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.

How many of their boys also have dimples?
Answer:
it's genetic
Explanation:
Baby cheeks are so sweet, pudgy, and pinchable. Pair those with adorable dimples and giggles and you have a baby akin to a kewpie doll.
Dimples are often seen as a desirable characteristic because they light up a face, even through smudged, terrible-two tears. They definitely seem to provide a little more personality!
But how do you know if your baby will have dimples? It’s a question that many soon-to-be parents ask themselves. The answer lies within miniscule, curly things called genes.

What process is depicted in the following image?
Conjugation
Transformation
Binary fission
Transduction
Answer:
its transformation! so option B
Explanation:
Within the image you can see the final product is a "Genetically Transformed cell" and within lesson 03.01 HONORS on flvs there are multiple dropdowns giving definitions. one of these dropdowns contains this exact image, and it is titled 'Transformation' in the lesson.
I am currently taking this course, so actually searched brainly for that answer initially. I decided to take the test and come back with the right answer to help any other students like me! A tip for taking tests on flvs: You can have flvs open on multiple tabs, so the best way to take tests like this is to have the test open on one tab, and the lesson plan on another tab. That way you can read through the lesson and look at any graphs while actively in the test! Hope I could help at least a little, have a great school year everyone.
is vinegar a solution?
There is an enzyme in your stomach. Explain how the enzyme would be affected if it was moved
the small intestines.
Answer:
It might not work as efficiently because the conditions are different
Explanation:
The stomach is highly acidic compared to the small intestine. That means the pH is higher in the small intestine. Stomach enzymes are adapted to work at low pH, but might not work at a higher pH as in the small intestine. They might not be able to efficiently catalyze reactions in the small intestine.

According to natural selection theory, Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes Adaptations beneficial at one time should generally be beneficial during all other times Well-adapted individuals have more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals. Adaptations beneficial in one habitat should generally be beneficial in all other habitats
Answer:
The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.
Explanation:
Adaption in natural selection is a species, time-specific, and habitat-specific process. So, it means if a species is adapted to genetic changes in a particular habitat, it is not necessary that all other species also adapt to similar genetic changes.
Similarly, if a species has beneficial adaption for a particular habitat, it is not necessary it will be beneficial for the other habitat as well.
Thus, natural selection leads to the well-adapted individual that leave more offspring and contribute more to the gene pool.
Scientists have a theory about the relationship between climate and biodiversity. Which best describes this theory?
Warmer climates promote higher biodiversity, allowing plants to grow year-round. This supports more organisms that rely on plants.
Colder climates promote higher biodiversity, reducing the competition among organisms for food. This supports stronger organisms that live longer.
Warmer climates promote higher biodiversity because they tend to receive more rainfall. This provides a source of water for more organisms.
Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.
Answer:
c
Explanation:
"warmer climates promote higher biodiversity because they tend to receive more rainfall. This provides a source of water for more organisms."

Describe why Canada geese migrate to meet their basic needs.
Answer:
Canada Geese migrate because when winter gets harsh the lakes, ponds, and streams all freeze over so then the Canadian Geese can't eat, so they migrate to somewhere where there is open water. ... From their original home in the North the Canadian Geese fly all the way down to the south.
Explanation:
Answer:
Canadian geese eat grass, during the winter in Canada the snow either covers all pf the available grass, or it dies. So they travel to warmer, southern regions where their grass is still abundant.

Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST
Your answer:
Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.
Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?
Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.
