The answer is a hair root.
Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, d<span>ead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.</span>
Answer: Carbon Dioxide (CO2)Aerobic organisms (like us!) are organisms that need oxygen. That means they consume oxygen (

)and release carbon dioxide (

).
That
carbon dioxide is the waste product that is taken up by plants during photosynthesis to create more oxygen and sugars (as "food" for the plants). This is seen in the equation for photosynthesis, where the things that are consumed by plants are on the left of the arrow, and the things produced are on the right:
<span>
6CO2 + 6H2O + light energy ==> C6H12O6 + 6O2</span>
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.
All 3 farming techniques are methods of soil conservation.
Contour plowing is used to stop water from flowing directly down slope to prevent gullying.
Terracing is used to slow the amount of runoff, and prevents rapid soil erosion.
Strip Cropping is when farmers plant plants in alternating bands to stop soil erosion.
The parents (P1) will be all red. The monohybrid snapdragons producing red and white seeds in the ratio of 3:1 with the red (R) phenotype being dominant and white(r) being recessive, might possibly have the parents with the following genotypes:
Rr (Red) Rr (Red)
The gametes produced by these parents will be R and R. The cross of these parents (P1) will result in the following generation that will be in the ratio of 3:1 (red:white) :
