At the end of the winter they are most numerous in fresh water. they will cover surface of aquatic plants or poles and wooden borders of ponds. If you like to study them you can scrape the brown growth with a flat piece of plastic. you can also use a sponge. for the free living (plankton) species fine mesh plankton net is very useful.
D. genes are found in specific locations on a chromosome
The answer is A. The sulfur-filled fluid that comes from the vents is lethal to some animals.
Deep-sea vents are hydrothermal vents at the bottom of the oceans. The mineral water that comes from them is rich in sulfide and methane and can be lethal to the most of animals. However, some bacteria are able to survive in such conditions thanks to the process of chemosynthesis. Chemosynthesis is a process in which some bacteria produce sugar, similarly to photosynthetic process. But, while in photosynthesis the energy of Sunlight is used to convert carbon dioxide and water into sugar and oxygen, in chemosynthesis, carbon dioxide, oxygen, and hydrogen sulfide are used to produce sugar, along to water and sulfur. This process is preferable when there is no light and the environment is rich in sulfide or methane, such in deep sea vents.
Answer:
all of the above
Explanation:
All the statements are true that is Sweating is an example of positive feedback because when you sweat your body becomes hot and your inner body becomes cool. Shivering is an example of negative feedback because shivering occurs when there is cold in the body and can lead to sickness. The nervous system is responsible for sensing changes in the environment because it is responsible for sensing what's going on in our body.
