Answer:
The lymphatic system is a complex system of fluid drainage and transport, and immune response and disease resistance. Fluid that is forced out of the bloodstream during normal circulation is filtered through lymph nodes to remove bacteria, abnormal cells and other matter.
lymph circulation. The flow of lymph from the tissues into the lymphatic collecting system. ... It is collected into lymph capillaries, which carry the lymph to the larger lymph vessels. These converge to form one of two main trunks, the right lymphatic duct and the thoracic duct.
Understanding the lymphatic system's role in immune cell trafficking and immune responses, contribution to fat transport, distribution, metabolism and implication in the pathogenesis of chronic intestinal inflammation may provide the basis for new therapeutic strategies and improved quality-of life.

Answer: Both N.locustae and protist Mixotricha paradoxa do not have a mitochondria.
The mitochondria is a basic cell organelle that palys the role of energy generation for the cell.this energy generated is in the form of ATP.
The organism N. locustae tends to rely on it's host cell that is that grasshopper. This host cell is that in which N. locustae replicates inorder to get a supply of energy.
On the other hand,the organism Mixotricha paradoxa relies on the bacteria endosymbionts to be able to supply it with energy.

1) Sucessão ecológica é o nome dado a uma série de mudanças que ocorrem nas comunidades de um determinado ecossistema. Sobre a sucessão primária, marque a alternativa correta: A sucessão primária ocorre em uma área que já foi ocupada por uma comunidade anteriormente. A sucessão primária pode acontecer em áreas desmatadas, por exemplo. A sucessão primária ocorre em ambientes estéreis, onde nunca houve a ocupação por seres vivos. A sucessão primária é o último estágio da sucessão ecológica.
Answer:
A sucessão primária ocorre em ambientes estéreis, onde não havia vestígios de organismos vivos que a ocupassem antes. Esse ambiente pode ser um local vulcânico em que a lava derretida destruiu o meio ambiente ou foi causada por dunas. A comunidade inicial de organismos para habitar esses ambientes é conhecida como sucessores primários ou colonizadores primáriosrimários
Explanation:
Primary colonisers initiate primary succession as such they are important to the future of such environments. They are though breeds of organisms that make use of scarce resources to survive in harsh environments. Without their ability to survive, there will be little or no way other forms of succession can take place. Reasons, why they may not persist, maybe too much stress imposed on them by the environment and above all their inability to compete when other successors come on board.

explain briefly the process of nutrition in amoeba
Explanation:
amoeba is an microscopic unicellular organism found in the moist soil ponds and lakes. When amoeba comes in contact with food ,it produces pseudopodia around the food particles the food get trapped in food vacuole. Digestive juices are secreted into the food vacuole to digest the food. The digested food is absorbed and used for production of energy. the undigested food present in the food vacuole, is expelled. from the amoeba, by the process of egestion

Explanation:
Concerns from Biotechnology
The use of biotechnology has raised a number of ethical, legal, and social issues. Here are just a few:
Who owns genetically modified organisms such as bacteria? Can such organisms be patented like inventions?Are genetically modified foods safe to eat? Might they have unknown harmful effects on the people who consume them?Are genetically engineered crops safe for the environment? Might they harm other organisms or even entire ecosystems?Who controls a person’s genetic information? What safeguards ensure that the information is kept private?How far should we go to ensure that children are free of mutations? Should a pregnancy be ended if the fetus has a mutation for a serious genetic disorder?
The ELSI issues are important and require to be maintained in order to maintain bioethics and examine various impacts of science and technology on the society.
What are ELSI issues?ELSI stands for Ethical, Legal, and Social Issues. It is a widely used acronym in the bioethics literature which encompasses a broad range of research work which mainly examines the various impacts of science and technology on the society.
The ultimate mission of the ELSI Research Program is to support the research and education activities which include promotion of genetic privacy and fair use of genetic information, encouraging the responsible integration of new genetic information and technologies into clinical and non-clinical settings, and to ensure that the genetic research is being conducted in ethical way.
