Answer:
A. Bacterial species use a limited number of nutrient sources.
Explanation:
There are two classes of nutrients that are indispensable to bacteria: macronutrients (carbon, oxygen, nitrogen, sulfur, phosphorus and hydrogen) and micronutrients (iron, zinc, manganese, calcium, potassium, sodium, copper, chlorine, cobalt, molybdenum, selenium, magnesium, among many others). But it takes more than the nutrients for them to feed, it takes the metabolism, because it is through it that they transform what they have into food.
The absorption of nutrients to carry out the metabolism only occurs because there are growth factors (environmental) that influence the development of the bacteria. Some examples of these factors are: light, temperature, pH, oxygen and osmotic pressure. Each organism has an optimal growth temperature, or a favorable pH to successfully carry out its metabolism. This will vary from species to species.
Answer:
Increasing
Explanation:
This particular question or problem can be likened to a deductive reasoning. The viral disease known as HIV stand for Human Immunodeficiency Virus which is a disease that damages the immune system of anyone affected with the disease. The Human Immunodeficiency Virus goes through four main stages or steps that is to say the infection stage/step, the stages in which the symptoms does not show, the stages at which the symptoms start to show and the stage at which the Human Immunodeficiency Virus goes or turns to AIDS.
The frequencies of these "resistance genes" In human populations where HIV infection is common will increase. When Human Immunodeficiency Virus infection is common, people in that particular society will develop more resistance to the virus and the survival of the fittest is taken into account as people with more resistance tends to be more healthier than the ones with less resistance.
Biomechanical mechanisms, habitat for plants and animals, participates in cycling of all materials used by living things.
