Answer:

Organisms niche is determined by its position, status in its habitat and its adaptation with its environment.

Explanation:

The ecological niche is the position, status, feeding habit, and adaptation to the organism's habitat. If the habitat is the address of the organism, the ecological niche is the profession of the organism. Many organisms can stay in a single habitat, but their niche is different. The ecological niche prevents the competition of the organism. It helps a large number of the species to occupy a single area. An ecological niche is determined by an organism's status, adaptation to the physical, chemical, biological factors of the palace it lives.

e.g. Some species occupy a large area, and they feed on different foods. Man in some regions is a carnivore, in other herbivores, but in most cases, they are an omnivore.

After phosphates and nitrates have entered a water
frosja888 [35]

After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.

Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.

Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:

  • Algal bloom: the nutrients facilitate the rapid growth of algae
  • The bloom of algal species results in the death of underwater plants as a result of inadequate light.
  • The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.
  • Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia

Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

The microorganisms that inhabit the sludge at the bottom of a lake would live in which microbiota zone
Margaret [11]

Answer:

Explanation:

In a lake, oxygenic phototrophs produce new organic material as  well as O₂. If primary production rates are very high, the resultant  excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions.  This in turn stimulates anaerobic metabolisms, including  anaerobic respirations and fermentations.

Organic matter that is not  consumed in surface layers sinks to the depths and is decomposed  by anaerobes.

Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by
Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.  

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
