Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
Explanation:
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.
Primary consumers only eat primary producers such as herbivores and secondary consumers are carnivores and omnivores
DNA samples are added into wells with the help of electric current.
<h3>How dna samples added to the wells?</h3>
DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
So we can conclude that DNA samples are added into wells with the help of electric current.
