Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
Okay so for
Flock X: The food percentage is 41% ,and the Simulated Number of Birds in Flock for 2nd Generation is 12.
Flock Y: Food percentage - 33% , Simulated Number of Birds in Flock for 2nd Generation is 10.
Flock Z: Percentage - 26% , Simulated Number of Birds in Flock for 2nd Generation is 8.
Answer:
THE DOMINANT GENE CAME FROM THE FATHER TO ONLY THE SONS THE RECCESIVE GENE WENT TO HIS DAUGHTERS
Explanation:
Cyclopropane is a highly strained molecule because the conformations of the cycloalkanes are influenced by the torsional, angle strain, and steric strain. Cycloalkanes, which comprises more than three atoms of carbons are not flat molecules, they are puckered.
The three and four-membered ring components exhibit angle strain and minimize the internal bond angles. The angle strain is generated when the bond angles deviate from the optimum tetrahedral angle, that is, 109.5 degree.
Torsional strain is a resultant of eclipsing interactions, and steric strain is attained when the atoms are forced too close to each other.
Abnormally the slow depolarization of the ventricles would most likely change the shape of the QRS in an ECG tracing. It is a combination of three graphical deflections which is seen on a typical electrocardiogram. It is the most visually obvious and central part of the tracing. It corresponds to depolarization of left and right ventricles of the human heart.
During the activity, it may be shorter in children.
QRS waves occur in succession rapidly. Q wave is a downward deflection following P wave. R wave follows upward deflection and S wave is downward deflection which is after R wave while T wave follows S waves.
