Pride can be a positive trait as it helps an individual gain confidence in their work and skills, making them more successful and happier. However, pride can be negative as it may cause one to believe they are entitled to their success, and also may cause them to treat others inferiorly. Hope this helps! :)
The right answer is C.
Classically positive interactions or facilitators between species are divided into two broad categories:
- those where the two partners involved benefit from each other: the mutualisms (symbolized by + / +)
- those where one of the two partners makes a profit or an advantage while the other gets nothing from it without being affected negatively: it is the commensalism symbolized by + / 0.
It may be that bacterial commensalism has an interest in its host (the animal) in the sense that it protects against parasites, or on the contrary, it favors their appearance.
Ecosystem and pond,
not sure though but good luck !
<span>The second statement is correct. Viruses can infect all cellular life forms, but each cellular species
can be infected by own limited specific range of viruses. Most viruses that harm
animals can not harm humans. But, some viruses can infect different species of mammals, for example both
bats and humans can be infected be rabies.</span>
