The crayfish is a relatively large specimen, even the mouthparts. Since you are dissecting the mouthparts, you need a 3D view: you should use the dissecting microscope.
Food doesn't taste good during common cold because you can't smell it properly
Yes it is.
Carbon dioxide goes through plants, which they turn into oxygen. Humans and animals take in the oxygen and breathe out carbon dioxide. Then it repeats.
Answer: The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth's temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.
Explanation:
Answer:
B. The biomass of leaf litter in the bags will be greater in leaves with higher lignin content after the same length of time.
Explanation:
Lignin is a major, one of the most slowly decomposing components of dead vegetation, including leaf litters. The lignin content has been found to have a high correlation with litter decomposition.
<em>Hence, at the end of the experiment, the litter bag containing leaf litters with higher lignin contents will be expected to weigh more than those with lower lignin contents.</em>
The correct option is B.
