It is crucial to study ocean microbes because THEY CONTROL THE MAJOR BIOGEOCHEMICAL CYCLES THAT KEEP EARTH'S BIOSPHERE IN BALANCE.
The ocean is made up of many microbes, which play important role in the process of biogeochemical cycling of various elements. For instance, microbes play very important role in the biogeochemical cycling of carbon and nitrogen. In the nitrogen cycle, the microbes are responsible for breaking down the protein molecules that are found in the body of dead plants and animals. The proteins are broken down into constituent amino acids, which are then released back into soils. The soil used these ammonia as sources of nitrogen for growing plants.
Answer:
Explanation:
La contaminación de mares y océanos es una realidad creciente en estos tiempos y esto tiene graves consecuencias para la vida marina, como problemas de desorientación, alteraciones en las cadenas alimentarias, toxicidad para la fauna marina, destrucción de los ecosistemas marinos e, incluso, acaba habiendo también consecuencias para el ser humano.
En este artículo de EcologíaVerde veremos exclusivamente cómo afecta la contaminación del agua a los animales marinos, pues es necesario tomar consciencia del perjuicio que supone este gran problema ambiental para todos y no solo para las personas.
For walking, a group of four muscles, known as Quadriceps muscles are the most important. A complete bed rest for a longer period of time causes the reduction in the flexibility of the quadriceps. So, in order to prepare a person for ambulating after a long bed rest, the nurse should focus to restore the flexibility in the quadriceps. This can be done by alternating flexing and relaxing the quadriceps. This exercise would help in reviving the strength of the quadriceps.

Answer: genetic variation is a mutation or a change in the sequence of DNA. It can be preserved if that sequence is needed for a species to survive ( evolution). It can also be preserved if that sequence is strong enough to be passed down from mother to child. The mutation can be eliminated if it causes distress to the animal or if it makes the animals chances of survival smaller. If an extra fin on a dolphin helped it to better escape its predator and better obtain food then this trait may stick around because it is beneficial to the species. If the fin cause the dolphin to swim slower then the dolphin may not survive to reproduce or the trait will not pass on.
