DAILY TEST 1 SEMESTER 3 SASING

There are only two modern species of these fish, i.e. the plankton-feeding American paddlefish (Polyodon spathula) and the piscivorous Chinese paddlefish (Psephurus gladius).

Paddlefish are not closely related to sharks. However, they have several body parts that resemble those of sharks such as their skeletons and deeply forked heterocercal tail fins.

Paddlefish provide important economic, ecological and aesthetic values. During the last century, paddlefish and sturgeon have been commercially exploited for their eggs (roe) called caviar.

Paddlefish and sturgeon are two of the most important fish for freshwater caviar. Their unique shapes and large sizes also add to the joy of nature for humans, including sport fishing.

However, exploitation and habitat changes, among other factors, have significantly reduced the population of paddlefish.

 From the text we know that paddlefish .....

• Have similar skeletons as sharks.

• Have a common shape.

• Are mostly exploited for its meat.

• Have a small and long mouth.

• Have unique shapes and large size similar with sharks

After reading the text, it is expected that the readers ...

• Consume paddlefish.

• Sell and buy paddlefish.

• Preserve paddlefish from extinction.

• Breed paddlefish in aquariums.

• Hunt paddlefish for some money

However, exploitation and habitat changes, among other factors, have significantly reduced the population of paddlefish.

Why does the population of paddlefish decrease?

• They are predators.

• People commercially exploit them.

• People destroy their habitats.

• They are difficult to bread.

• The climate changes

Scientists believe that people inherit their affection for the scent of rain from ancestors who relied on rainy weather. Therefore, what makes rain smell so nice? There are several scents associated with rainfall that people find pleasing. One of these odours is called petrichor.

Several plants secrete volatile oils during dry periods. These oils are the compound of chemical organisms. It makes the oils the compound of chemical organisms. It makes the oils have tiny molecules and can be easily distilled in the atmosphere. When the rains fall, these oils are released into the air.

The second reaction that creates petrichor occurs from soil-dwelling bacteria. Those bacteria, known as Actinomycetes, produce chemicals. The chemicals are released. These aromatic compounds combine to create the pleasant petrichor scent when rain hits the ground.

Another scent associated with rain is ozone. During a thunderstorm, lightning can split the oxygen and nitrogen molecules in the atmosphere. They can recombine into nitrate oxide in turn. This substance interacts with other chemicals in the atmosphere to form ozone. It has a sharp smell faintly reminiscent of chlorine.

It is possible for people to say that they can smell rain coming. The wind from an approaching storm has carried ozone down from the clouds into the people's nostrils.

How can volatile oils from the plant be released into the atmosphere?

• The thunderstorms break the oils apart.

• The oils evaporate because of cold.

• The oils are mixing with the nitrogen.

• The molecules are distilled in the air.

• The molecules hits the ground when raining

What do people actually smell when rain comes approaching?

• The petrichor brought by wind.

• The oxygen scents in the air.

• The fragrant oil produced by plants.

• The smell of died soil bacteria.

• The chemicals in the atmosphere come approach when the storms
