Answer:
Plants need chlorophyll to conduct photosynthesis
Explanation:
Fossils are the preserved remains, or traces of remains, of ancient animals and plants
Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.
D. The daily release of hot water into the pond from a local factory.
Explanation:
The daily release of hot water into the pond from a local factory would most likely affect the health of fish in a local pond.
Fishes are cold blooded animals. They derive their temperature from the water around them. They need a fairly stable daily temperature.
If the temperature of the water varies to a large extent too much daily, they will suffer.
Hot water will affect the fish population badly. It will cause the fishes to die off and suffer from too much increase in temperature.
Other factors listed in the options will improve the fish life.
