Biology
1 answer:
vodomira [7]3 years ago
3 0

Answer: Nasal breathing drives oxygen more efficiently into the lower lobes of the lungs rather than staying in the upper lobes as in mouth breathing. With nasal breathing, all five lobes of the lungs are used to breathe rather than just the upper two. The lower lobes of the lungs have more parasympathetic, calming and repairing nerve receptors which are activated during nasal breathing exercise. The upper lobes have more sympathetic or fight or flight stress receptors that are activated during mouth breathing exercise.

Hence we can conclude Individuals with favorable variations survive and reproduce.

GarryVolchara [31]

<u>Correct option/s </u>:

All plants are multicellular.

All plants are eukaryotic.

All plants are autotrophic.

<u>Explanation</u>:

Not all plants are vascular, for example mosses. They don't have specialized system for transport of water and solutes. Therefore, Option 1 is false.

Only bacteria, protista and yeast are unicellular. Rest all the organisms are multicellular. Thus option 2 is true.

Only bacteria are prokaryotic, rest all organisms are eukaryotic, including all the plants. Option 3 is true.

Plants are the only organisms which are autotrophic. Although apart from this mode of nutrition, plants can be parasitic or carnivorous as well. But primarily they all are autotrophic. Option 4 is true

Not all plants need sunlight, some get energy from the chemical substances from their surroundings. Option 5 is False.

Plants reproduce by sexual as well as asexual means. Not all plants reproduce sexually. Option 6 is false.
