The dry cleaning industry is the primary user of the chemical perchloroethylene (PCE). The research done by the researchers at the Boston university have found that the PCE chemical increases the risk of developing mental illnesses in the people working with it. Since, it is a common name in the dry-cleaning industry, the workers in this industry are much more prone to mental illnesses a compared to other people.
Hence, the answer is 'dry cleaning industry'.
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
The role of a Detrivore is to help recycle the nutrients in the soil. They break down complex proteins, and other materials so the answer is A. to decompose dead animals.
Answer:
There are four subsystem of earth that includes lithosphere, hydrosphere, biosphere and atmosphere.
Ocean is included in hydrosphere and is one of teh largest subsytem in the earth. <u>The two input and output to the ocean subsytem are as following:</u>
- The wind energy (input) transfer to ocean surface affects the motion of water in the ocean and produces waves (output).
- Heat energy recieved from the sun (input) is transferred toward the poles and allows the heat lost to the space (output).
<u>some of the interaction of ocean with other subsytem are as following:</u>
- Interaction between biosphere and hydrosphere (ocean): ocean provide water to living organism for survival and growth.
- Interaction between atmosphere and ocean is water cycle. The water from ocean evaporates through heat (sun) and through rain the water again reaches to the oceans.
