In biological definition, a vector is a self-replicating DNA that bears the desired gene to a new cell. When this happens, it receives no reward and loses fitness. It may relate to other vectors such as a plasmid, binary, cloning, shuttle, viral and others.
C would be the best choice. Protists are eukaryotes that basically aren't members of fungi, plantae, or animalia. There is ongoing debate about their taxonomy.
In eukaryotic cells the DNA is in the nucleus.
but in prokaryotic cells, it's in the
cytoplasm
good luck
Answer:
The correct answer is: ethmoid.
Explanation:
The ethmoid is a bone that is located in the anterior part of the skull ("at the front"), between the eyes, separating the brain from the nasal cavity.
The ethmoid has 3 parts: the cribriform plate, the ethmoidal labyrinth, and the perpendicular plate. The superior and middle nasal conchae are part of the ethmoidal labyrinth.
In the conchae resides most of the mucosal tissue necessary for respiration, which also provides the humidity required for olfaction, and also plays a part in the first line response of the immune system.
