Answer: True. Selective media can be used to separate gram negative from gram positive bacteria.
Explanation: Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms.
For example: Media containing potassium tellurite will inhibit the growth of gram negative bacteria while media supplemented with penicillin will inhibit the growth of gram positive bacteria.
Answer:
Due to change in genetic combination.
Explanation:
The results change as the number of trials increased because variation occur in the genetic combinations of chickens. It is important to breed the chickens repeatedly in this experiment in order to gain accuracy and attain best results. If the chicken is breed repeatedly, at the beginning changes occur in their offspring due to change in their genetic makeup so for accurate results repetition is necessary.
Lakes are large and loudish, whereas ponds are generally a lot more quiet and steady and small.
<h2>Answer and Explantion</h2>
Asexual reproduction is a kind of reproduction by which children emerge from a single organism and obtain the genes of that origin only, the union of gametes is not included and nearly never varies the number of chromosomes. Asexual reproduction enables people that are genetically identical to the parent plant. Plants can produce seeds without fertilization by the process of apomixis, then the ovary emerges to new seeds. Plants and fungi proliferate asexually.
