Answer: The image formed by a plane mirror can only be the same size as that of the object.
Explanation :
A plane mirror consists of a highly reflecting surface. This surface reflects a large portion of light. One of the surfaces is polished with red lead oxide.
The image formed by the plane mirror is of the same size as that of the object. The distance between the object and the mirror is equal to the distance between the image and the mirror.
Out of given options, the correct one is (d) " The image can only be the same size as the object ".
Answer:
recombinant DNA
A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA
Explanation:
Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.
Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.
This single DNA is known as Recombinant DNA
Answer:
D. Small population size
Explanation:
Hardy-Weinberg equilibrium requires the presence of a large randomly mating population. Small population size makes the population more likely to deviate from the Hardy-Weinberg equilibrium due to sampling error or chance events occurring during the genetic drift. Large population size ensures that the population maintains the constant allele frequencies over generations, that is the Hardy-Weinberg equilibrium.
Answer:
B. surface runoff
Explanation:
Surface runoff is the flow of water that occurs when excess storm water, melt water, or other sources flow over the Earth's surface.
