Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries,
B. To orient themselves and to find food
Since they cannot see very well or even at all in some cases, these animals use echolocation instead to orient themselves, to find where they are, and to find food.
When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the lysogenic phase). But when a dormant virus is stimulated, it enters the lytic phase: new viruses are formed, self-assemble, and burst out of the host cell, killing the cell and going on to infect other cells. The diagram below at right shows a virus that attacks bacteria, known as the lambda bacteriophage, which measures roughly 200 nanometers
b)ATP is the important energy storing molecule produced in cellular repiration
a)ATP stores and releases energy
Answer:
Al Capone, Fred "Killer" Burke, and Bugsy Moran.
Explanation:
Augustus "Smiling Gus" Winkler was a big-time gangster who had his fingerprints surgically altered so as not to be identifiable through fingerprint technology. He was part of Eagan's Rats gang and would participate in some of the most notorious crimes such as the St. Valentines Massacre in 1929.
When he moved up north, he met up with some of the world's famous gangsters like Al Capone, Roger Touhy, Fred Burke, and Bugsy Moran. But in 1933, to secure himself, he turned evidence against his friends and accomplices. But he was not to be safe for long, for he was gunned down by unknown assailants rumored to be ordered by Frank Nitti on October 9, 1933.
