Explanation:
Traditional antibiotics build immunity by exposing the memory cells of our body to inactive versions of viruses or bacteria.
True
False
Conventional antibiotics increase immunity by exposing our bodies' memory cells to dormant viruses or bacteria. So, the aforementioned is True.
What are Antibiotics?A particular class of antimicrobial agent that works against bacteria is an antibiotic. Antibiotic drugs are frequently used for the treatment and control of bacterial infections because they are the most effective type of effective antibacterial for doing so. Bacteria may be killed or have their growth suppressed.
Several types of bacterial infections are treated or prevented with the help of antibiotics. They either eradicate bacteria or stop them from proliferating and spreading.
Viral infections cannot be treated with antibiotics. This covers the typical cold, the flu, the majority of coughs, and sore throats. By introducing our bodies' immunological memory to latent viruses or bacteria, traditional antibiotics boost immunity.
Therefore, the given statement is True.

example of what type of mechanism?
Answer:
b number positive feedback
"A hole in the skin causes platelets to rush to the site and release a chemical that releases more platelets" is an example of a positive feedback mechanism. The correct option is B.
What is a positive feedback mechanism?A positive feedback mechanism is a technique of the body in which the body works or secretes something to the body that is needed more in the body, and it is secreted in the body out of league and number.
Platelets are present in the blood. They are spherical and are colorless and small. They help in blood clotting when there is a cut or bleeding, it prevents loss of blood by clotting the blood.
So, in the hole of the body, there will be blood loss, and releasing more platelets would help in blood clotting.
Thus, the correct option is B. positive feedback mechanism.

How does meiosis most benefit a species?
It decreases the number of chromosomes.
It increases genetic variation.
It increases the number of chromosomes.
It increases mutations.
Answer:
It increases genetic variation.
Explanation:
Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.
While it could increase mutations, this might not necesarily be a good thing.
However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.

web site: The de-extinction of the woolly mammoth would be an evolutionary mistake
1:As of recently, the essential contention for species de-termination was that it offered humankind an opportunity to make up for itself for the wrongs submitted north of millennia. People, one could really guarantee, have been messing up the planet since days of yore. Thus, a large number of the species that have been the objectives of de-termination endeavors have been picked on the grounds that they appear to have some essential thing right to make due. Frequently, they look similar as species that have made due until the present time. Assuming it hadn't been for people meddling with their normal natural surroundings and sensitive environments, the contention goes, they would have been prospering today.:2To get around this contention, however, a few researchers are beginning to put forth the defense that it wasn't Mother Nature who did in the wooly mammoth — it was people. When the planet began to defrost, people came into contact with the wooly mammoth in more prominent numbers, and started to chase them savagely after their meat, bones and even skin. It's basically the traveler pigeon proposal, stretched out to the wooly mammoth. De-eradication fans will most likely let you know that people bear a sort of transformative responsibility for having cleared out the wooly mammoth, quit worrying about environmental change.:3creating a highly-controlled environment (i.e. a theme park) where the wooly mammoth could conceivably flourish – it doesn’t reason that you can simply hit the “rewind” button on evolution. As some conservationists are already warning, bringing back a species like the wooly mammoth could lead to the disappearance of other species who share similar habitats. Once you bring back a new species, you have to start thinking about ecosystem effects — and about Butterfly Effects. Bringing back the wooly mammoth would require massive changes to existing ecosystems.:4Yet, that equivalent contention – an opportunity to reclaim human bad behaviors over an improper annihilation – doesn't hold on account of the wooly mammoth. The wooly mammoth, with its monstrous hair coat to save warmth, had no way for endurance once the Ice Age finished. As Darwin originally guessed, advancement resembles a calculation followed commonly. In the event that a variation assists an animal varieties with getting by and thrive, the transformation will stick. Assuming it doesn't, it will ultimately vanish from the genetic stock. For better or for more regrettable, certain species will go terminated when they can presently don't adjust to their current circumstance. It wasn't only that wooly mammoths had substantial hair coats – they had a wide range of different variations that assisted them with flourishing during the Ice Age, as enormous tusks to clean up snow and ice. Bringing back the wooly mammoth would be commensurate to bringing back an animal types that had the right to go terminated. : main idea Accepting totally effective cloning to make sound creatures, the cloned wooly mammoths would in all likelihood have hopeless existences and couldn't have ever evident freedomWhat's more not just the productive restoration of the wooly mammoth, but it's full rewilding into the Arctic." Bringing species like the wooly mammoth back into the frosty might perhaps help deferred down non-renewable energy source side-effects in the area and help with restoring lost organic frameworks, Lamm said.But think about how conceivable it is that they somehow made due. Our Arctic regions would look an incredible arrangement changed, and not because there would be huge assessed, shaggy animals meandering around. There would be less elk, moose, and caribou considering the way that the wooly mammoth would out battle them for food.Assuming absolutely viable cloning to make sound animals, the cloned wooly mammoths would probably have miserable presences and couldn't have ever clear freedomLamm said expecting the association is productive, research has shown bringing back ended species could reshape the Siberian tundra and in other Arctic regions to be more specialist of the normal game plan of the Arctic glades when it was an unrivaled carbon-sequestering areaLamm said assuming the organization is effective, research has shown bringing back wiped out species could reshape the Siberian tundra and in other Arctic districts to be more agent of the biological arrangement of the Arctic fields when it was a superior carbon-sequestering location.But imagine a scenario in which they some way or another made due. Our Arctic locales would look a ton changed, and not on the grounds that there would be enormous measured, shaggy creatures meandering around. There would be less elk, moose, and caribou in light of the fact that the wooly mammoth would out contend them for food.
