PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each
Grace [21]

Answer:

There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.

Explanation:

Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.

Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.

Which of the following populations would be considered r-selected? Black Widow Spiders - they produce 1000s of offspring and few
belka [17]

Answer:

Option 1.

Explanation:

r-selected species may be defined as the species that has higher growth rate, shows less parental care and the rate of survival of the off spring is low as compared  with k selected species.

Black widow spiders have the ability to produce 1000 offspring. Their chances of survival are extremely low and only few species of black widow spiders survive. Hence, black widow spider is r-selected species.

Thus, the correct answer is option (1).

What would the result be if a drug that blocks the action of rna polymerase was introduced into a virus-infected organism?
Svetllana [295]

Answer:

The correct answer is: viral replication would stop.

Explanation:

Drugs that block the action of RNA polymerase in viruses are called antivirals and are used to cure viral infections like Hepatitis and Herpes.

<u>Antivirals do not destroy the virus but rather mess with its development by inhibiting its replication</u>.

Viruses do not have the capacity to replicate or synthesize proteins by themselves, so they need a host that can "lend them" the structures needed to perform those processes. If the drug blocks the RNA polymerase, the virus won't be able to replicate itself.

A brick is lifted above the ground and then dropped,
xeze [42]
The answer is C, gravitational potential to kinetic, but just a side note beware of posting questions that are that kind of evaluation. People can track you down for using any sort of site for help. So just keep in mind just send in the picture but not type in the entire question so that way you don’t get detected or have to retake the entire thing. Good luck btw
