a predator population suddenly decreases even though the prey population stays the same. Besides disease, what could explain this change?
Answer:
hunting, the predator is in the middle of the food chain
Explanation:
hunting can WIPE OUT species as shown by the dodo bird in the past.
food chains often work as 1-2-3 or 1-2-3-4 in levels.
A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.
What happens if in a particular food web a new prey animals are introduced?If in a particular food web a new prey animals are introduced, that will most likely result in the increase of the populations of the predators in that food web. The reason why the populations of the predators would increase is that there will be more pray to hunt, and more food means that the predators can increase in numbers and not suffer from food shortage.
Still, while this the most likely scenario, it has to be taken with a little bit of reserve, as it also depends on what kind of prey animal would be introduced in the food web, and what kind of predators are there in the food web. The predators in that food web are small to medium sized predators like the serval, honey badger, than there will be no increase in the predator populations as they will not be able to hunt the introduced pray animal.
Therefore, A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

Achieving Anastasia’s Dream
Part 1
Remember Anastasia? To refresh your memory, she is a high school science teacher who has the dream of traveling the world. Anastasia decides that if she teaches a science course online, she will be able to work from anywhere in the world if she has an internet connection.
To construct her course, Anastasia needs to put together a rough course calendar. Her course is going to be on biology or the study of living organisms. The course has eight sections, with each section covering three to six subtopics. Each subtopic takes a week to cover.
Here are the sections in the course. To help Anastasia out, do some research online and find at least three subtopics for each section. (You could look at websites such as k12.com or textbook publishers such as Houghton Mifflin Harcourt or Prentice Hall to see what topics are typically covered in these types of courses).
Biology Foundations
Cells
Energy and Transport
Reproduction and Cell Division
Classical Genetics
Molecular Genetics
Human Body Systems
Ecology
That is a lot to fit in! Anastasia needs her course to consist of 36 weeks’ worth of lessons. Create a 36-week chart to help Anastasia fill in her lessons so that she knows when each topic will be covered. Fill in the subtopics that you found and spread them out evenly so that all topics are covered in Anastasia’s 36-week period. Anastasia will use your chart as a course calendar. Don’t forget that one subtopic takes a week to cover. Some sections may take more weeks to cover than others, depending on the number of subtopics included, and that is just fine!

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms include a high fever, headaches, and body aches typically occur two to seven days after infection by the virus. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is-
Answer:
lytic, due to the quick onset of symptoms after infection
Explanation:
There are two different mechanisms by which viruses can replicate: the lysogenic cycle and the lytic cycle. The lytic cycle is a reproductive cycle where viruses hijacks the host cell's machinery in order to rapidly produce new viruses, which subsequently burst out of the host cell. On the other hand, the lysogenic cycle is a type of viral reproduction characterized by the integration of the viral nucleic acid into the host cell genome, staying hidden. In consequence, this cycle (lysogenic) is slower compared to the lytic cycle because it requires an additional step (i.e., genome integration).
Answer:
lytic, because of the quick onset of symptoms after infection.

What sort of symbiotic relationship do rodents and humans share?Whether we like it or not, these rodents are called commensal, which means they have a symbiotic relationship with us humans and profit from us and our homes.
What genetic variations exist between rats and mice?Although both are rodents, they differ genetically in that mice have 20 pairs of chromosomes whereas rats have 21 pairs. The size of the faeces is often used to identify the animals. Compared to mice, rats often live slightly longer.

D. North America has no volcancus.
Explanation:
its b i think if its right your welcome if its not let me know
The evidence for continent drift theory is that places with hot climates once had glaciers. Therefore, option B is correct.
What is continental drift theory?According to the Theory of Continental Drift, the continents of the Earth move relative to one another and appear to be drifting over the ocean floor together.
Wegener constructed a ring around the south pole using the regions that had been ice-covered. The conclusion of the theory is, Over the past 300 million years, the continents have drifted to their present locations after having formerly been a single, bigger continent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift. Hence, option B is correct.
