Answer:
The sample a which is solid at 20°C is "Iodine"
The sample b which is liquid at 20°C is "Bromine"
The sample c which is gas at 20°C is "Chlorine"
Explanation:
Iodine : It starts melting at 113.7°C, so the solid sample found is the iodine. Iodine is present in both solid as well as in vapor state. Basically it is kept in closed jars. Only when it reaches the temperature above the melting point is starts melting.
Bromine: It is a non metallic element that is present in the liquid state, being a member of halogen group. It is heavy, mobile and dangerous reddish brown liquid. It is corrosive in nature, when comes in contact with human tissue and causes irritation in eye when comes in contact with its vapor.
Chlorine: In room temperature it is gas, as it has weak intermolecular interaction which fails to keep the molecules closely attached.
The Yellowstone River ecosystem can support 2,300 bald eagles. This is an example of<u> temperate- zone ecosystems</u>
Explanation:
Yellowstone National Park is a natural paradise with over 70 species of birds,which include trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles
The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles
<u>Temperate ecosystems are the ecosystem that are characterized by the seasonality in temperature, with cooler winters and warmer summers, and also show various seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.</u>

Answer:
Reasoning and understanding is performed by the Pre-frontal cortex which is the part of the frontal lobe where is the other major part that deals with the implementing and planning approaches performed by the dIPFC.
Prefrontal cortex which is the part of the frontal lobe is not present in lizards and frogs, as they have limbic system which is phylogenitcaly very primitive.
O'Brien mentions that Winston writes Newspeak elegantly. He also alludes to Winston's comrade, Syme.
