Experiment that will look into the effect of wind speed on rate of transpiration is the setting up of potometer with fan.
<u>Explanation:</u>
A device that is used to estimate rate of transpiration by measuring the water loss / uptake rate is called Potometer. It takes up the water loss rate into consideration and lets us determine the transpiration rate.
Wind speed is one of the major factor which affects the rate of transpiration. The air bubble introduced in the potometer, lets us record the transpiration rate which can be checked for effect of wind speed by varying the speed of wind artificially in an experimental setup of potometer using fan to circulate air around the plant.
The effect of wind speed is thus recorded, as when the wind speed is higher than usual, the transpiration rate is found to be increased and vice - versa.
Answer:
open, close
Explanation:
The trachea is cartilaginous tube which connects pharynx and larynx to lungs and thus allowing passage of air.
C-shaped cartilages are open at area where trachea is nearest esophagus, which leads from throat to stomach. <u>It reinforces anterior and lateral sides of trachea to maintain airway open.</u>
The trachealis muscle bridges gap between free ends of the C-shaped cartilages at posterior border of trachea and is adjacent to esophagus. <u>The primary function of trachealis muscle is to constrict trachea, allowing the air to be expelled with more force during coughing. </u>
<span>Rats have a uterus comprising of the right and left cornua (horns) referred to as a bicornuate uterus. This way the rat can support multiple fetuses, this structure enables the rat to have multiple offspring. The uterus accepts eggs and supports the growing embryos development until birth. </span>
