D. Fingerprinting involves binding radioactive probes to label DNA that has been digested by an endonuclease and separated out
Answer:
Option (D)
Explanation:
The existence of a good and favorable ecosystem depends upon certain factors such as temperature, rainfall, and sunlight. In a place where there is abundant rainfall, sunlight and moderate temperature, there occurs an ecosystem that is rich in a variety of species as it provides the necessary elements that support the existence of a favorable ecosystem. Due to the moderate temperature and good amount of precipitation, the soil in this ecosystem gets the required nutrients that help in the growth of different species of plants and trees. This given condition reflects a tropical type of ecosystem where there are numerous trees and also a huge variety of species exists. The tropical ecosystem lies in the equatorial and near-equatorial region on earth.
Hence, the correct answer is option (D).
Answer:
Peptidic bond (proteins), glycosidic bond (carbohydrates) and lipid bond (lipids)
Explanation:
1. Peptidic bond: this type of bond is exclusive for the aminoacids. These monomers create bonds between the carboxylic acid of first and the amino grupo of second (like a acid-base reaction). We have notice, some aminoacids monomers have groups acid or amino into the primary ramification, it groups cannot react to form peptidic bons.
2. Glycosidic bond: principally, this bond is form between the carbon alpha of one monomer (monosaccharide) and one hidroxyle group (-OH) of other monomer. The number of the cabron that has the -OH grupo will bring the name to the bond, for example, "glucose 1-4 fructose". Also, we have a direction of the bond before the firs number, alpha or beta, it depends on the geometry of the monomer.
3. Lipidic bond: usually, it bond type is a coballent and create an anphipathic zone, this is why some lipis are not soluble in water
Oxygen (O2) and sugar(C6H12O6)
Answer:
The proportion of the sperm would carry the Bt gene is 1/2
The presence of the Bt gene is dominant
Explanation:
Bacillus thuringiensis (Bt) transgenic crops include, ammong, others, cotton, corn, and potatoes. The Bt transgenic crops are aimed at killing insect pests that feed plants and thus reduce crop yields
