Answer:
Endangered
Explanation:
Endangered species are organisms that are at risk of extinction if deliberate efforts are not made to conserve them due to a rapid decrease in their population.
<em>Hence, if a marine biologist writes an article about saving whales and labels them as </em><em>endangered species</em><em>, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem. Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable. </em>
Answer:
The correct option is <em>A) Carry out DNA cloning of the desired sequence into a plasmid vector and then put that into bacteria and wait for the bacteria to copy the gene every time the cells divide.</em>
Explanation:
The DNA can be easily cloned by the help of vectors like plasmids. Plasmids can be described as an extra-chromosomal ring which is present in bacteria. The plasmid has many multiple cloning sites where the desired DNA can be incorporated. the plasmid with the foreign DNA is then incorporated back into a bacterial cell. As bacterial cells like E.coli divide in a short period of time, many copied of our DNA could be obtained whenever the bacterial cell replicates.
Answer:
c
Explanation:
it weakens an ecosystem.biodiversity is the slight changes of one organisim to the next inside a species. when a species looses biodiversity, the traits that the one organisim had are gone and none of the others can adapt this trait. adaptation is what keeps speicies alive. thus, loss of biodiversity is bad and weakens an ecosystem.
Answer:
False
Explanation:
-Carbon has 4 electrons in its outer shell
-It can achieve a full outer shell by forming Covalent Bonds
Top right one, metaphase is where the chromosomes are lined up in the middle (metaphase=middle)
