Hello  <span>Fernandancon7965

It is not dangerous to eat the black part of a banana. It is just either ripe or bruised. Normally people find the taste unpleasant and prefer not to eat it.


Hope That Helps!

How did Mendel's<br> experiments provide evidence for the principle of<br> independent assortment?
Mrac [35]

Answer and Explanation

Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.

He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.

He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.

He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.

There is a healthy bacterial culture growing in the exponential phase . A technician wants to make a growth curve by making cell
emmainna [20.7K]

A) WHAT IS THE PROBLEM WITH HER PLAN?

Binary fission is one of the asexual process by which most bacteria reproduce, the binary fission brings about a doubling of the number in bacterial cells that are viable.

Generation time is that time that it will require for a cell population to divide and double, it is also known as doubling time. This Generation time varies among distinct organisms and also varies among culture conditions.

Take for instance,a fast growing bacterium that is under an ideal culture conditions has a doubling time of 20minutes and for the bacteria that is grown in a condition that is not so ideal,may have a doubling time of hours.

The major challenge/ problem with her plan is that as she takes the bacterial sample every 30minutes, and then hold the sample till the last sampling is done in the day,those bacterial cells that are collected in the initial intervals will then get divided and further gives a result that is false.

However,if those bacteria that are collected aren't stored in a culture environment that is standard,the bacterial cells may die off and thus will further bring about a false result.

2) CAN SHE DO ANYTHING TO IMPROVE THE ACCURACY OF HER RESULT?

Solution for rectifying the error in her plan;

She can go ahead and add 50-100 μl of formaldehyde to all the culture suspensions that she has and has taken every 30minutes.

As the formaldehyde will fix the bacterial cells,The optical density present in all those aliquots can then be retrieved/taken at the end of the day.

Looking at it alternatively, aliquot 1ml of the culture suspension at an interval of every 30 minutes,and then take the optical density that is OD at a wavelength of 600nm making use of spectrophotometer until the reason you get becomes static.

Samantha believes that flowering plants produce more flowers when they are given fertilizer. She designs an experiment in which
ZanzabumX [31]

Answer:

I think she should try the experiment one set with fertilizer, and one without. The negative control group would be the set of rose bushes grown without the fertilizer, but under the exact same conditions as the experimental group. Then, if a difference is seen you can be sure it's accurate, since you tested with and without fertilizer under the same conditions. Sorry if i am wrong, I am not completly sure about this one. Again I might be wrong so sorry in advance.
