Which of the following are biological marcromolecues

Who realized that fingerprints were unique to individuals?

Whitepunk [10]

1. I believe the answer is William Herschel.
Francis Galton is often credited with the discovery that everyone's fingerprints are unique and that they could therefore be used for identification. However his works is extensively based on the work of Dr. Henry Faulds, who appears to have a better claim to the discovery, along with British magistrate William Herschel.

2. I believe that the ratio of height to width indicate size and consistency in hand writing analysis. The ratio of height, width and size of letters is among the characteristics of handwriting analysis that entails whether the letters are consistent in height, width and size.

3. I believe the statement that describes the line quality in handwriting analysis is whether the letters are shaky or flow continuously. Line quality is an indication of speed and fluency; the better the quality, the more skilled, or at least fast, the movement of the pen.

4. The statement that best indicates pen pressure in hand writing analysis is the down strokes and upstrokes are an even width.
Pen pressure is the pressure equal or unequal when applied to upward and down ward strokes. The pen pressure of a writer indicates his physical and emotional energy.

5. I think what is measured in the ridge count is spacing between ridge lines.
Ridge counting is the the counting of the ridges that touch or cross the line of count drawn between the delta and core of loop patterns. A white space must always intervene between the delta and the first ridge to be counted.

Birds are the main predators of these beetles; they hunt the beetles by sight and pick them off the tree bark where they feed. A

Alinara [238K]

Complete question:

1. The graph below depicts the frequency of expression of the coloration of beetles on an island:

Graph is the 1st Pic --> Attached files

Birds are the main predators of these beetles; they hunt the beetles by sight and pick them up off of the tree bark where they feed. A logging company clears the trees off of the island and plants younger trees as a replacement. Trees with light bark are planted on one side of the island and trees with dark bark are planted on the other side of the island. What do you predict would happen to the range of coloration in the populations of beetles on each side of the island?

Select TWO answers, one to represent the beetles living on the light colored trees and one to represent the beetles living on the dark colored trees. (2 points)

A. graph 2 below

B. graph 3 below

C. graph 4 below

D. graph 5 below

Answer:

B. graph 3 below

D. graph 5 below

Explanation:

The original population of beetles (Graph 1) shows that most individuals had an intermediate phenotype between dark and light color. The graph expresses its highest point in the middle of the phenotypic ax, while the curve´s tails coincide with light and dark colors.

Probably, most of the trees inhabiting the whole island had some darkish color tone, which beetles used to camouflage and avoid predation.

When the company cleared the area and reforested, they planted light trees on one half and dark trees on the other half of the island. This change in the environment modeled the beetled phenotype, together with predation pressure.

<em>If we consider the whole original population, we should say that it went under a disruptive selection.</em> But if we think about the sides of the island separately, we could say that the population living on each side went under directional selection. We are not thinking about the whole population of beetled inhabiting the whole island, but two groups inhabiting each side of the island.

Graph 3 represents the beetles inhabiting the part of the land with dark trees. The population went under directional selection, and most of them turned into dark-colored to camouflage with the substrate in which they live.
Graph 5 represents the beetles inhabiting the other part of the land with light trees. The population went under directional selection, and most of them became light-colored to camouflage with the substrate in which they live.

If a scientist needs to use a large dataset to explore how corn grows in different soils, how would this data be classified? A.

Mama L [17]

Answer:

The answer is D. mixed methods.

Explanation

In Science when you have large data-sets of a Food product then you have to provide its description, Quality and Quality. Here is example for each part as,

Description:

The scientist have to describe the features of Corn grown in different soils. Corn length could be variable in different soils depending upon the nutrient contents of them.

Quality:

For any food product quality is most important factor. Scientist have to explain about the quality of Corn grown in different soils because each soil have a different environment of seed growth.

Quantity:

Finally, the data for the quantity will explain that which soil was more suitable to obtain higher yield of corn.
