Aleksandr [31]

Answer:

The correct answer is- Resistance

Explanation:

The ability of any organism in a population to tolerate a chemical like insecticide, pesticide or antibiotic which is designed to kill it or slow its reproduction is called resistance.

For example, the antibiotic resistance is seen in some bacteria like MRSA(Methicillin-resistant staphylococcus aureus). They gain this resistance because they have some variant traits in their genome which provide them resistance against these chemicals.  

These individual are selected through natural selection when the environmental condition changes and become adverse. So the correct answer is resistance.

While grazing, a buffalo stirs up insects. These insects are eaten by cattle egrets. What type of interaction does the cattle eg
marysya [2.9K]

<u>Answer:</u>

<em>The interaction the cattle egret exhibits with the buffalo is commensalism. </em>

<u>Explanation:</u>

<em>In the type of interaction called commensalism</em> between two organisms, one organism benefits from the  other while the other <em>organism is neither benefited nor harmed. </em>

When the buffalo moves around a field grazing it disturbs the insects and they fly away from the buffalo and the cattle egret which keeps following the <em>grazing buffalo eats the insects. </em>

The buffalo doesn’t benefit from this type of interaction. <em>A commensalism relation is a positive-neutral kind of relation. </em>
