Describe the ten percent rule, and explain what percentage of energy a dolphin would have after it ate a fish, that ate an insect, that ate some grass.
Answer:
The ten percent rule, also known as the law of ecological tithe, has to do with the effective transfer of energy that occurs at different trophic levels, corresponding to the use of one tenth of the energy from the immediate previous level.
Explanation:
The 10 percent rule was established by the english naturalist Charles Sutherland Elton, indicating that the transfer of energy from one trophic level to another is only 10 percent. This means that the level immediately above can only use one tenth of the energy produced by the level before it.
What percentage of energy a dolphin would have after it ate a fish, that ate an insect, that ate some grass?For example, if we say that grass produces 10000 Kcal, the insect that consumes it (primary consumer) will be able to use 1000 Kcal, the fish that consumes insects 100 Kcal and the dolphin that consumes the fish only 100 Kcal.
Grass → Insect → Fish → Dolphin
10000 1000 100 10
In the end the dolphin, a tertiary consumer, will only be able to produce 10 Kcal, when in the food web the producer had 10,000 Kcal.
The 10 percent rule is not entirely accurate, since the effective transfer can be less or more than 10 percent. However, in most cases, the average energy transfer is around 10%, which complies with the rule.

If estimates of an extinction rate 10,000 times greater than the background rate are correct, then what percentage of all species will be extinct by the end of this century
Answer:
25-50%
Explanation:
If the statistics are correct and if no changes are made, at the end of the century we will have about 25-50% extinction of the species of living beings that we know today. This will completely change the fauna and flora we know, as well as affect the availability of numerous resources which will impact human life in a drastic way.
For this reason, it is necessary to stimulate projects and attitudes aimed at preserving nature and the life of animals and plants throughout the planet, so that this situation can be reversed.
Dr. Drew is studying the effect of overexposure to UV radiation in mice. He discovers that mice that are exposed to high levels of UV radiation are much more likely to acquire cancer than mice that are not exposed to UV radiation. Which of the following best explains why high levels of UV radiation can cause cancer in mice?
Answer:
UV radiation can alter an organism's DNA molecules and cause mutations.
Explanation:
The penetration of Ultraviolet radiation into the mice will react with the DNA bases thereby causing oxidation of DNA.
However, during replications, the reactions between ultraviolet radiation and DNA bases usually fails to pair normally, hence, a mutation occurs. This is otherwise known as Oxidative mutations.
Hence, in this case, the correct answer is "UV radiation can alter an organism's DNA molecules and cause mutations."
why it is so important for the body to be protected against viral pathogens?
Answer:
Certain viral pathogens can lead to death. Viruses like Human Immunodeficiency Viruses (HIV) are not considered lethal on their own but lower your body's ability to fight infections, and over time cause Acquired Immunodeficiency Syndrome (AIDS). If infected by this virus you could be killed by the common cold. That is why it is important to be protected against viral pathogens.

Which best describes how food availability affects the carrying capacity of an area?
A . as food availability increases, the carrying capacity increases in aquatic food webs only.
B. as food availability increases, carrying capacity increases in all ecosystem.
C. as food availability increases, the carrying capacity decreases in terrestrial food webs only.
D. as food availability increases, carrying capacity decreases in all ecosystem.
Answer:
I believe your answer would be "B"
Explanation:
If the food supply increases for a spider, they will reproduce faster, creating more food for the next animal in the food chain, and then that animal will reproduce faster, creating more food for the next animal, and so on! This would create more room for more animals because they can reproduce faster and create more all together.
Have a blessed day, please mark BRAINLIEST if correct! :D
The statement that best describes how food availability affects the carrying capacity of an area is as food availability increases, carrying capacity increases in all ecosystems. Thus, the correct option is B.
What is Carrying capacity?Carrying capacity may be defined as the maximum number of individuals that can live in an ecosystem without undergoing competition.
The increase in food availability gives the organisms the energy for survival and reproduction through which they can produce their offspring in the natural environment.
Almost all types of ecosystems favor food availability when it talks to increasing carrying capacity. Because the fact behind this concept remains the same for all ecosystems.
Therefore, the correct option for this question is B.

Based on the results of this study, what questions remain unanswered? How can these questions guide future research?
Answer: One of the biggest questions is, Can we replicate these results in other plants? So, there needs to be more research to determine whether this technique is effective in food crops. It’s not known what the protein PsbS does, even though it seemed to enhance plant growth. There should definitely be more research to find out how this protein is linked to plant growth and whether boosting this protein will affect growth in other types of plants. The researchers also noted that there are numerous other ways to make photosynthesis, and there are more than 100 chemical reactions involved in the process. Investigating other possibilities might be the key to improving crop yield in a wide variety of crops.

Do analogous structures show an evolutionary relationship between two species (meaning do they show that individuals with analogous structures come from a common ancestor). Example: Flies and birds have wings. Do wings show that a fly is related to a bird?
Answer:
The correct answer is - NO.
Explanation:
To be specific to the question, the answer would be no as analogous structures do not show that two distinct come from a common ancestor. However, it shows the evolutionary relationship by stating that the species have different evolutionary origins and developmental patterns as they developed the organs with similar function and appearance but anatomically and embryological development is different.
The answer to the question "Do wings show that a fly is related to a bird?", is no it does not show the relation between fly and bird.

How does having genes on many chromosomes, rather than on just one chromosome, increase genetic variation among offspring?
Answer:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes
Explanation:
Due to the possibility of genetic material being recombined and shuffled during meiosis, having genes on several chromosomes as opposed to only one chromosome enhances genetic variety among kids.
What is genetic variation among offspring?At locations known as chiasma, the chromosomes overlap. The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
The chromosomes align in pairs and cross over during the meiotic process to exchange genetic material. This process results in novel gene pairings on the chromosomes, which can result in the birth of kids with distinctive combinations of features.
Therefore, the possibility of genetic material being recombined and shuffled during meiosis increases genetic variation among offspring.
