Answer:
option a. streak, pour
Explanation:
The best method to isolate single bacterial colonies is the "streak-plating" method.
The "streak-plate" procedure is used to isolate pure cultures of bacteria or also colonies, from mixed populations by mechanical separation. Millions of cells form a colony, they grow in a cluster on an agar plate. With this method, a mixture of cells is spread over the surface of a agar-based nutrient in a petri dish, that makes that less bacterial cells are deposited at widely separated point on the surface and, after incubation, they develop into colonies.
On the other hand, the best method to count colonies is the pour plate method. It helps to enumerate bacterial cells in a mixed sample, often used to count the number of microorganisms in those samples, which are added to a molten agar medium before its solidification occur. The result is colonies uniformly distributed throughout the solid medium when the appropriate sample dilution is plated.
A) Lipase would be inactivated
Hope this helps!
uracil
Explanation:
because the rest are part of the DNA strand
~ C. Population
Population is all the inhabitants of a particular town, area, or country.
Answer:
The correct answer would be option D) no gametes.
Explanation:
The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.
Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.
The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.
Thus, the correct answer would be option D) no gametes.
