Some problems with use of DNA analysis for forensic evidence may occur because of
alisha [4.7K]

Answer: Option D " all of the above "

Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.

Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.

Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.

Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.

Hence, the correct answers are all of the above.

In Drosophila, straight wings are dominant to curved wings (c), smooth eyes are dominant to sparkling eyes (spa), and tan body i
77julia77 [94]

Answer:

\frac{1}{8}

Explanation:

Straight wings are dominant over curved wings

Let Straight wings : H

curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Again; Let tan body color be H

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be \frac{8}{64}

= \frac{1}{8}

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the
NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.

What is the effect of uneven heating of the earth's surface on the environment ​
zhannawk [14.2K]

When people speak about convection, they are usually referring to the uneven heating that occurs on the surface of the earth.

Consequences of an inconsistent heating system:

Because of the disparity in temperature distribution, certain areas of the environment are hotter than others, and there are also shifts in volume and tension as a result.

It generates updrafts, which in turn may lead to thunderstorms and other types of severe weather.

The Earth has moved slightly on its axis.

Because the sun's rays are directed directly at the equator, the temperature there is higher than in other parts of the planet.

As you approach farther north or further south of the equator, they drop down in an incline or at an angle.

Because of this, the temperature of the earth is uneven, which in turn shapes the wind and the flow of the sea and makes it possible for life to exist.
