Answer: C
Explanation:
Use DNA from hair follicles of supposed zoo parents and of the supposed offspring to compare sequences amplified with primers for a highly polymorphic region.
DNA sequencing and comparison is a way for checking if two individuals are closely related. Comparison of the sequence of the parents to the supposed offspring will indicate if indeed there was a relationship or if it was imported.
Answer;
High-energy electrons pump hydrogen ions against the concentration gradient.
Explanation;
-The electron transport chain sets up a proton concentration gradient across the inner mitochondrial membrane, with more protons outside the membrane.
-As a result of this gradient, the protons are waiting to get across the membrane. This happens through the transmembrane protein ATP synthase, which uses the energy moving protons through its pore to add a phosphate to ADP, thus producing ATP.
1.The thermosphere: is used for orbitting satellites and increases in temperature as altitude increases.
2.Convection currents in the mantle cause the movement of crustal plates.
Answer:
<u>vacuole</u>
Explanation:
Vacuoles are filled with cell sap which contains sugar, salts and waste products and enclosed by tonoplast, a membrane. They mostly act as a store for sugars and salts, they maintain the shape of the cell and play a role in osmoregulation. They are found in both plant and animal cells.
