Answer:
A living organism whose genes have been purposefully altered
Explanation:
The given blank can be filled with selecting.
It has been shown by Belyaev and Trut that foxes can be domesticated, over the time of various generations, by selecting and mating animals with certain traits, like responses to feeding, handling, and others.
A sustained multi-generational association in which one group of species presumes a substantial extent of effect over the care and reproduction of another group to secure a more predictable supply of resources from that latter group is known as domestication.
Answer:B
Chorionic Villus Sampling
Explanation:
This is a prenatal test which involves taking a chorionic sample from the Placenta for testing
Answer:
A myosin head bound to actin
Explanation:
Cross bridge cycling explains the sliding filament theory according to which thin and thick filament slide against each other for muscle contraction. The two myosin heads extend form the thick filament. One myosin head has binding site for ATP and other head has binding site for actin from thin filament.
When myosin head binds to actin a cross bridge is formed. When ATP binds to the other head the bridge dissociates. Actin binding site is free and myosin tries to bind with other actin during which ATP is hydrolysed into ADP and Pi. Myosin along with the ADP and free Pi successfully binds to another actin molecule. The cross bridge formed generates a powerful force and ADP and Pi are displaced from it. The cross bridge is now free again for binding of next ATP molecule and the cycle continues.
