The correct answer is option B
Species interactions are categorized based on their reciprocal effects (the effects that the interaction has on each species/individual involved).
1. Bees pollinate plants as they move from flower to flower collecting pollen.
This is a mutualistic relationship because the both species involved in this interaction benefit from the interaction. The bee benefits because it obtains nectar which is provided by the plant. The plant benefits because the bee carries the plants pollen to other plants, allowing the plant to reproduce.
2. Green algae grow on the backs of spider crabs living in shallow water.
This is another example of a mutualistic relationship because both species involved in this interaction benefit from the interaction. The spider crab benefits from the camouflage that the algal growth provides, while the algae benefits from the protection from predators provided by the spider crab.
3. Fleas living on skin of dogs and obtaining nutrients from dogs blood.
This is a parasitic relationship because one of the species benefits from the interaction while the other species in negatively impacted by the interaction. The flea benefits from the nutrients obtained from the dogs blood while the dog is negatively impacted by the fleas presence (loss of blood, discomfort).
4. Nitrogen-fixing bacteria obtain nutrients from host plants and use the nitrogen to supply host plants with nitrogen.
This is an example of mutualism because both species in this interaction are benefitting from the interaction. The nitrogen fixing bacteria benefit by receiving nutrients from the host plant while the host plant is benefitting from receiving nitrogen from the bacteria.

Denaturation refers to the loss of protein three-dimensional structure when temperature or pH is altered.
Denaturation is the phenomenon in which the tertiary structure of the protein is broken down due to the breakage of bonds between the amino acids of proteins. This breaking of bonds occurs due to the change in pH or temperature from the normal at which the protein remained active.
Three-dimensional structure of the protein is its form in which the protein remains active and functional. It is generally tertiary structure of protein. This active tertiary structure is decided by the sequence of amino acids in the primary structure of protein, where the protein exists as a linear chain.

Answer:
Trees are known as producers, plants and autotrophs in ecology.
Explanation:
The other cause that should be considered is HEMATEMESIS.
Epitaxis refers to nose bleeding. When a patient complains of nose bleeding, other possible bleeding locations in the body should also be examined. This is done in order to ensure that no other type of contained bleeding, that may be fatal to be patient's health is not going on in the body.
