<h2>The correct answer is: Mutualism.</h2>

Explanation:

  • Mutualism can be defined as a type of symbiotic relationship.
  • Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
  • Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
  • In the given question, some micro-organisms survive in the digestive tract of the cattle.
  • These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
  • On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.

Which of the following will NOT facilitate the transfer of oxygen to tissues?
bija089 [108]

Answer:

decreased body temperature

Explanation:

Muscles also need oxygen to function properly. Given that blood flow must be maintained at high levels to supply oxygenation and muscle substrates, mechanisms have been found to facilitate this process. Among the processes that facilitate the transfer of oxygen to tissues, we can mention lowering blood pH, increasing carbon dioxide and increasing exercise.

Lower body temperature, in turn, makes it difficult to transfer oxygen to tissues, causing fatigue, pain and other problems.

Which five organs make up the vestibular system? A. Three semicircular canals and two otolith organs B. Two semicircular canals
enot [183]

Answer:

Option A

Explanation:

The vestibular system is a part of the inner ear that provides the most important contribution to the sense of balance and coordinating movement with balance. This system is made up of two parts which are the three semicircular canals and the two otolith organs. The two otolith organs are the saccule and the utricle. The utricle is sensitive to changes with regards to horizontal movement and the saccule provides information about vertical acceleration. They are able to do this due to their orientation in the inner ear providing spatial orientation with regards to movement and balance. the three semi circular canals includes the horizontl, poterior and the superior semicircular canals. they provide sensory inputs.
