Answer:
plasmid
Explanation:
Plasmids are small circular double or singe stranded DNA molecules that are distinct from the main chromosomal DNA. They are used in genetic engineering as vectors for replication of foreign DNA or proteins using bacteria as a host organism. The DNA strand is integrated into the plasmid DNA to form a recombinant plasmid that is then transformed into the host.
Plasmids are ideal vectors because of the following characteristics:
- High copy number per cell
- Multiple cloning sites
- Have an origin of replication
- Have antibiotic resistance gene
There are also diffrent types of plasmids:
- Degradative
- Virulence
- Resistance
- Fertility
- Col plasmid
Answer:
The correct answer is: <em>Zonosemata flies with housefly wings are attacked less frequently</em>
Explanation:
The Zonosemata experiment is a scientific experiment that was conducted to investigate how zonosemata flies are able to protect themselves from predation by jumping spiders. In this study, housefly wings were transplanted onto zonosemata flies. This made zonosemata flies protected from attack by jumping spiders. On the other hand, when zonosemata wings were transplanted onto houseflies, they were easy targets for jumping spiders. Therefore, if the sub-hypothesis that wing waving alone reduces predation by jumping spiders is proven, the logical result would be that: Zonosemata flies with housefly wings are attacked less frequently.
A neuron is a nervous system cell specialized in the communication and information processing between the nervous system and the various organs. It is present under different structures (multipolar, unipolar, bipolar ...).It consists of three main parts:
*A cell body also called soma, it is composed of the cytoplasm and the nucleus of the cell that contains the DNA to encode the proteins necessary for the function of the neuron.
*Tree extensions that are also called dendrites, its role is to receive information.
*A single axon with the ability to route information to other cells.
