Answer:
Bacteria are microorganisms and they are useful to us. Bacteria are economically important as these microorganisms are used by humans for many purposes. The beneficial uses of bacteria include the production of traditional foods such as yogurt, cheese, and vinegar. Microbes are also important in agriculture for the compost and fertilizer production. Bacteria are used in genetic engineering and genetic changes.
When evolving, microorganisms such as harmful bacteria may develop a resistance to antibiotics. This means that the disease the bacteria in question cause will be harder to treat. This is quite bad since bacteria can pass on traits to other bacteria without even multiplying.
The flu virus is also a good example. Generally, the virus itself mutates quite frequently. This means that with each mutation the virus has a potential to gain a genetic trait which may cause more severe flu symptoms or a resistance to drugs/the antibodies our bodies produced to counter-attack the type of flu virus it has previously encountered.
Answer:
(4) tissues
Explanation:
There are three circles the innermost circle indicated the cells middle circle is the tissues and the outermost circle indicated the organs. Multicellular organisms are made up of thousands of different types of cells .Different cells constitute together forma a tissues and different tissues form a organ and different organs together form an organ system. Hence the X labeled circle denotes the tissues.
Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.
The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous <em>"</em><u><em>Powerhouse of the cell</em></u><em>"</em> title. Mitochondria produce energy in the form of ATP.
ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.
In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.
