Based on the anatomical and physiological differences between an infant and an​ adult, which finding would suggest respiratory d
frosja888 [35]

Answer: Excessive movements of the walls of the  abdomen

Basically babies belly breathe, that is they undergo abdominal pattern of respiration( instead of the abdomino- thoracic pattern in  adult), through their abdomen.

<u>This is because,  their thoracic walls are not fully functional to undergo  the normal adult mechanisms  of breathing</u>.

<u>The ribs are short in length due to incomplete ossification. They curve out wards, at low angle, their sternum, is shaped horizontally.</u>

These features reduce the activities   of the inter coastal muscles and the thoracic cage  in the mechanism of  infants breathing,compare to the long ribs, obliquely shaped rib cage,  with lower  sternum  of  adult which  permit the  abdominal-thoracic  breathing pattern.

Therefore ,when the diaphragm distends during breathing ,its movement pushes the organs of the abdomen down; because infants have rapid respiratory  rates, the distends created  rapid  expansion and contraction of the walls of the abdomen to gain enough abdominal pressure.

This together with the movement of  organs of the abdomen   from  the  pathways of diaphragm  created the  excessive  movements of the abdominal walls. This rapid abdominal wall movements creates discomfort and distress for the infant during this mechanisms.

1.) Making an observation.
2.)Asking questions.
3.)Forming a hypothesis.
4.)Conducting an experiment.
5.)Analyzing Data.
6.)Drawing a conclusion.
7.)Showing work to others.

Publishing his/her work would be the very last step after completing everything else.

Euglenas are unicellular organisms. They are both self feeder and other feeders. Which statement summarizes the heterotrophic ac
lukranit [14]

Answer:

The best answer from the list of options is option D (They are colorless and feed on other, smaller cells)

Explanation:

Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.
