Reported or indirect speech is usually used to talk about the past, so we normally change the tense of the words spoken. We use reporting verbs like 'say', 'tell', 'ask', and we may use the word 'that' to introduce the reported words. Inverted commas are not used.
Answer:
it's curve1000 for this question
The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
Answer:
Some mutagens strip DNA nucleotides (bases) of essential modifications—for example, they deaminate the bases—such that these bases resemble different nucleotides and confuse the DNA replication machinery. Subsequent rounds of DNA replication then permanently incorporate such changes.
Explanation:
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
