Hello! The polar jet stream contains strong winds that moves weather around different parts of the globe. It affects the weather and temperature, because they push air masses around, and separates warm and cold air. Cold fronts formed from cold air represents represents low pressure systems, which consists of rain or other precipitation, while warm fronts represent high pressure systems and sunny weather. They play an effect on air transportation, because planes travel faster along the jet stream, but they also have to do with global warming.

<span>Marine ecosystems like lakes and oceans have aphotic zones. Aphotic zones refer to the zones in the water where there is little or no sunlight. It is found in bodies of water were depths only receive less than 1% of sunlight penetrations. Bioluminescence is essentially the only light found in this zone and most food comes from dead organisms that sink at the bottom of lakes or oceans. </span>
Answer:
Answer is E. No males can be found.
Explanation:
The rotifers are invertebrate aquatic multicellular organisms. They are freshwater aquatic organisms with the possession of circles of strong cilia, which they use for locomotion, and thus the name wheel-bearer.
The Rotifers are grouped into three classes , which are Seisonidae, Monogononta and Bdelloidae.
The way of reproduction in these classes differ. The Seisonidae reproduce sexually, Monogononta reproduce sexually or asexually, and the Bdelloidae reproduce asexually.
The Bdelloidae reproduce asexually because they did not have males. They female produced the offspring from an unfertilized eggs . This process is known as pathenogenesis.
In this case, the Bdelloidae is the class that reproduce mainly by asexual reproduction because no male can be found.
