How to count volume​
Novay_Z [31]

The SEC dictates how volume is counted. Thus, volume is counted in the same manner on all markets based on the above reporting structure. Any time money changes hands (or any time capital is risked), it must be counted as a trade. Examples: 1) One registered market participant on Nasdaq buys 100 shares into inventory from another registered market participant or from one of its clients. In either case, it is counted as 100 shares. 2) One member firm on the NYSE or Amex buys 100 shares from another member firm. The Specialist matches the order between the two firms and it is counted as 100 shares. 3)The Specialist sells 100 shares from his inventory to a member firm on the NYSE. It is counted as 100 shares. 4) A Market Maker receives an order to buy 100 shares from it's client. It does not have 100 shares in its inventory. It must go buy 100 shares from someone else. It then sells these 100 shares to the client. Thus, there are two trades in this example for a total of 200 shares.

hope this helps (:

Why are birds that inhabit areas with high acid deposition more likely to lay eggs with thin shells?
stiks02 [169]

Answer:

C

Explanation:

When it precipitates, the acid in the soil becomes dissolved forming an acidic solution. The low pH solution dissolves the calcium ions in the soil washing them away in runoffs and also leaching them deeper into the soil. This depletes the calcium ions hence making them unavailable to the birds. Calcium intake is important in birds because the ion is a significant component of eggs shells  (makes them strong and not brittle hence the eggs don’t break easily)..
