If you are referring to selection pressure, when the selection pressure decreases, there will be weaker forces of natural selection. The angler fishes without the favourable traits would not be that strongly selected against and vice versa. In some cases such as predation selection pressure, the population of angler fishes in the habitat may increase
Smooth muscles depolarize as a result of a transmembrane current of Calcium ions. When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.
The National Institutes of Health found it effective in reducing pain and other symptoms, but it is not clear how it works.
The air gap is filled with gas which increases the insulation between the glass pieces. Double glazed windows are highly efficient, reducing your heat loss or gain by up to 30% when compared to single-glazed windows.
Answer:
No, there are no organisms that will not fall into these categories
Explanation:
Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:
- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.
- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.
- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.
Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.
