A major disturbance that the ecosystem was able to recover completely from.
Hello. Your question is incomplete. However, I managed to find a question exactly like yours on the internet and managed to realize that you forgot to say that your question asks you to give an example of the statement presented above.
Answer:
A major disturbance from which the ecosystem was able to recover completely was the disease that almost wiped out all of Ireland's potato in 1840.
Explanation:
You may have heard of the Irish Potato Famine, which was a time when the Irish population lived very difficult days, after an illness that almost decimated the country's potato plantations.
The potato was the main source of food for the Irish, but in 1840, a fungus called Phytophthora infestans, managed to infect almost all potato plantations in the country, preventing the potato from being harvested and could be consumed. This created major economic and social problems in Ireland, as people suffered from hunger, poverty and the diseases that arose, which caused many Irish people to immigrate to other countries, or to die.
The fungus plagued the ecosystem for years and only started to decrease in intensity in 1850, once the ecosystem started to recover. Currently, although the pest still exists, the Irish ecosystem is completely recovered and the pest is controlled and is unable to make such an impact.

What might occur if the stoma were all located on the top of the leaves?
Answer:
It depends on the plant and its environment. In a mesic terrestrial environment, the plant wouldn’t be optimized. Natural selection would then come into play and there would be an evolutionary trend towards stomata located on the lower leaf surface.
In the case of water lily, the lower epidermis is in contact of the water, and stomata are restricted to the upper surface of the leaf. This is an optimal solution for the plant. Natural selection will work to conserve that arrangement. In this case, stomata on the lower surface would exist at a water-air interface, and the diffusion of gasses across that interface would be glacially slow. Further, the stomata on the lower surface would present an opening where pathogens can enter the leaf.

When resistant bacteria multiply, what do they pass on to the next generation?
Answer:
Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.
The resistant bacteria can reproduce rapidly because their competition (the non-resistant bacteria) has been destroyed by the antibiotic. When the resistant bacteria reproduce, they produce genetically-identical copies. These copies will all be resistant to the antibiotics.

What is the next step to take to identify a fish that has a single dorsal fin and no fin on the back near the tail?
step 5
step 2
step 7
step 6
Answer:
The next step to take to identify the fish is step 7.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
carefully observe your organism, know some technical terms or have a biological dictionary, and follow the descriptions.The dichotomous key is going to lead you to the answer. Each step states two descriptions -a and b-, that are the potential answers. You need to observe your specimen and see which of the descriptions matches the organism. Once you choose the correct description, the key leads you to the next step. In the next step, the procedure is the same. You have to repeat it until you reach the name of your organism.
So, in this example, our organism is a fish, and we know that it has a single dorsal fin and no fin on the back near the tail. So,
1. (a) Has a single dorsal fin ---------------- step 5
(b) Has a double dorsal fin ----------------step 2
We have two options, single dorsal fin or double dorsal fin. Our fish has a single dorsal fin, so the correct option is (a). By choosing (a), the key sends us to step 5. Note: In the hypothetical scenario of having a double dorsal-finned fish, the correct option would be (b), which would lead us to step 2.
5. (a) Has small fin on the back near tail ---------- step 6
(b) Has no fin on the back near tail -------------- step 7
Again, we have two options, with a back fin near the tail, or without. Our fish does not have any back fin near the tail, so we choose option (b). This option leads us to step number 7. Note: In the hypothetical scenario of having a fin in the back near the tail, we should choose option (a), which leads us to step 6. But this is not the case. So we go to step 7.
7. (a) Tail is asymmetrical --------------- step 8
(b) Tail is symmetrical ----------------- step 9
Once in 7, we need to see if our specimen has a symmetrical or asymmetrical tail. Depending on the answer, we go to step 8 or 9. And so on until we get to know the name of the fish.
Answer: The correct answer is step 7
Explanation: Confirmed correct.
2. What are the steps of the dichotomous key?
Answer:
1.list down the characteristics
2.Organnize the characteristics in order
3.divide the specimens
4.divide the specimens even further
5.draw a dichotomous Key diagram
6. test it out

Archaebacteria and eubacteria are classified into different kingdoms, but at one time they were both classified in the Kingdom Monera. Which statement best describes why the classification of these organisms was changed?
A. The kingdom became too large and had to be made into two smaller kingdoms.
B. New biochemical data showed different evolutionary relationships within the kingdom
C. The archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
D. Chromosomal analyses indicated a new genetic combination had arisen within a certain organisms in the kingdom.
Answer:
I think the option C is correct
The statement best describes the classification of these organisms was changed is the archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
What are the characteristics of Archaebacteria?Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.
Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences.
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution. bones (homologous structures) are used for similar uses if the organisms are more closely related bones (homologous structures) are used for similar uses if the organisms are more closely related sections of DNA are more similar in organism more closely related. sections of DNA are more similar in organism more closely related. organisms that are more closely related are found with similar embryonic structures. organisms that are more closely related are found with similar embryonic structures. fossils in various layers are more closely related if they are in the same layer
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.
