Determine whether a nail would be chiral or achiral.

Biology

weeeeeb [17]3 years ago

A nail may be considered as an achiral object because it can be superimposed when it is faced in a mirror image where in it may look exactly the same rather than chiral when they are in a mirror image, it wouldn’t be superimposable.

Based on the data, what is the probability a randomly chosen cell will be observed undergoing cell division? You may use the cal
dexar [7]

Answer:

A

Explanation:

<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>

Total number of cell in division = 20+4+2+4

                = 30

Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>

     = 30/200

          = 0.15 or 15%

The correct option is, therefore, A.

The answer is; Varicosities are recognized by the enlargement of the veins. Superficial veins are most likely involved because they have little support from surrounding tissues. The veins have become tortuous and dilated because of incompetent valves that allow the blood to pool, stretching the vein walls. The likely cause in this patient's case is her pregnancies, because the enlarged uterus exerts download pressure on groin vessels, restricting return blood flow to the heart.

A phenotypic ratio for a dihybrid cross is predicted to be 9:3:3:1. The experimental values are:
Maslowich
Two traits that we are examining are the color (purple/white) and the smoothness. 
In our sample, we have 135 individuals ( 75 +28+24+8= 135).

Since we know that expected ratio of a dihybrid cross, is <span>9:3:3:1 we can calculate what is the expected values of each phenotype is.

So, for the white wrinkled phenotype, we expect that there will be one-sixteenth of the whole sample ( there are 16 parts of the whole sample 9+3+3+1=16).
So, we multiply the whole sample- 135 with one-sixteenth (or </span>0.0625) and get 8,4375.
When you calculate the values for all phenotypes you get results shown in the attached excel table.
When you have your expected and experimental values you compare them with a chi-square test. (The test determines if the difference between the expected and experimental results is statistically significant).

Which statement is true about the environment of urban areas
emmasim [6.3K]

The promise of jobs and prosperity, among other factors, pulls people to cities. Half of the global population already lives in cities, and by 2050 two-thirds of the world's people are expected to live in urban areas. But in cities two of the most pressing problems facing the world today also come together: poverty and environmental degradation.
