Answer: Autonomic: Acting or occurring involuntarily, without conscious control. Central nervous system: The part of the peripheral nervous system that transmits signals from the central nervous system to skeletal muscles, and from receptors of external stimuli, thereby mediating sight, hearing, and touch.
Explanation:
Theory because a theory is a well substantiated explanation of how a particular phenomenon works based on the set of facts which had been repeatedly confirmed through observations and experiments. A scientific theory gives reliable account of a phenomenon.
Answer:
Option (d).
Explanation:
DNA is the genetic material of all the organism except some viruses. DNA is composed of nitrogenous base, deoxyribose pentose sugar and the phosphate group.
DNA replicatese by semi-conservative mode of replication in which one the daughter DNA consists of one newly synthesized strand and one parental strand. This mode of replication was explained by Messelson and Sthal experiment. The cells from 15N medium are transferred to 14N medium the band of intermediate density was observed. The daughter DNA consists of one 15N DNA strand and one 14N DNA strnd. This strand undergo replication in the 14N medium. This time one low density DNA band ( contains 14N - 14N DNA strand) and one intermediate density band ( 14N-15N DNA).
Thus, the correct answer is option (d).
Gorillas are a predator. They eat food and rarely ever get killed for food. But if we take away their habitat by making buildings and houses then they will die for other causes like hunger. If the gorillas go extinct then the food change will get all messed up. The food they normally eat will over populate meaning the food gorillas eat (like fruit) will over populates and take over the area. That means it will start to take up the space that other plants need to grow. The other plants that other animals will need to eat will slowly start moving away because their food is dying. They will start to go somewhere else and mess up that habitat too. Those animals will eat the food needed by the animals that lived there originally and food will become scarce for animals that all need the same type of resources.
D, a net transfer of energy
