Heterotrophs or heterotrophic nutrition .
The second option is the right one.
For DNA replication to occur, an existing double-stranded DNA (dsDNA) must be “unzipped” to form two strands of single-stranded DNA (ssDNA). The ssDNA then serves as the scaffold onto which a complementary strand of DNA is built by adding nucleotides one by one. At the end of this process, there are two identical strands of dsDNA, which then move into the daughter cells.
Answer:
Mutualism
Explanation:
Mutualism is also referred to as inter specific cooperation, a phenomenon in which two organisms from two different species co-exist in such a way that both get benefit from each other, either from their activities or from their fitness. Such behavior is commonly termed as cooperation.
Here in example, we see that saguaro cactus provides food for the white-winged dove through its large fruit. The bird eats that fruit but along with fruits it also ingests the seeds present in fruits. SO, when the bird flies to some new location, it drops the seeds there. In this way cactus can colonize new lands and spread offspring in new places while birds get their food. Both get benefit so it was a mutulalistic relationship.

Carbon dioxide is transported in the blood from the tissue to the lungs in three ways:1 (i) dissolved in solution; (ii) buffered with water as carbonic acid; (iii) bound to proteins, particularly haemoglobin. Approximately 75% of carbon dioxide is transport in the red blood cell and 25% in the plasma.
