Was the streak plate method effective at diluting the population size in all 4 plates?
Inessa05 [86]

Answer:

"Yes" The streak plate method is very effective in diluting the population size in all 4 plates.

Explanation:

The streak plate method is effective because it is one among the rapid isolation method which further allows for easy observation of the bacteria. This method is also being used for getting the color of the certain substances. Its main principle is to isolate the specific bacteria from the sample of various microbes. It dilutes the microbes number and often reduces their density. It is useful in separation of organisms from the group. These are isolated in the agar plate.

5 facts about the reproductive system
svp [43]
<span>After you ovulate, your egg is fertile for between 24 to 48 hours and a man’s sperm can survive in the female body for 48 hours. There have actually even been documented cases of live sperm surviving in the female reproductive system for eight days after intercourse!One breast is always larger than the other. Most of the time, it goes without notice but it is typical for breast size to be slightly mismatched. Some women can be born with two uteruses or two vaginas and have no idea until they notice abnormal menstruation or excessive bleeding. You are born with all the eggs you will ever have in a lifetime which can be anywhere from thousands to millions however, only about 300 to 400 of these eggs will mature and be released for fertilization. <span>You ovaries take turns each month releasing eggs.</span></span>

Every spring, each mature female fish of a particular species produces several million eggs. however, the total population of th
lidiya [134]
One of the reasons why the fish population remains approximately the same from one generation to the next is because not all the eggs laid will survive to adulthood. There are several factors which bring about elimination of the the newly hatched eggs. Examples of these are predators and diseases which eliminate the young offsprings at different stages before they develop into adulthood. 
Secondly, production of many eggs by the different fish species leads to competition for survival. Resources such as water, food, oxygen and shelter have to be fought for and its only the fittests that will be able to survive till the reproduction stage.

Rudik [331]

Answer:

transformation is carried out by random uptake of DNA, and transduction by a bacterial virus

Explanation:

Transformation and transduction are two of the three processes bacteria uses in genetic recombination (the third being conjugation). As rightly stated in the question, both processes establish that DNA is the genetic material of most living organisms and they both involve transfer and expression of DNA from cell to cell.

However, both processes are different in the way they get the foreign DNA into the bacteria cell.

- Transformation involves the random uptake of foreign extracellular DNA by the host bacterial cell.

- Transduction involves the transfer of foreign DNA into a bacteria cell via a virus called BACTERIOPHAGE. N.B: A bacteriophage is a virus that infects a bacteria host.
