The results will most likely be valid because the scientists kept getting the same results after REPEATED experiments. If they just conducted one experiment then they would not have been sure if what happened was a fluke or if another thing would happen after another experiment.<span />
Answer: C. the total amount of air that can be inspired after a tidal expiration.
Explanation:
The inspiratory capacity can be define as the highest volume of the air that can be inspired after the expiration. It is the sum of the the inspiratory reserve volume and tidal volume.
The tidal volume is the measure of the amount of air inspired and expired during the process of normal breathing. This includes the volume of around one to half liter. The expiratory reserve volume is the additional air which is exhaled after normal exhalation.
Answer:
A fruit fly of 75h AEL is at larval stage.
Explanation:
The development of a Drosophilia starts from egg to larva to pupa then to adult. The full development at 25 degrees Celsius takes between 8.5 to 10 days. The higher the temperature, the faster the development of the Drosophilia.
The eggs hatch after 12-15 hours into larval stage which then lasts for 3-4 days(72-96 hours) then the pupal stage which also lasts for 3-4 days before it becomes a full adult.
Thus, 72 hours after egg laying would still be in larval stage. The larval stage ends after at leas 90 hours after egg laying.
Answer:
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

The lymphatic system destroy harmful substances 'By producing antibodies'.
The lymphocytes contained in lymphatic organs are produced with other defence cells by the bone marrow. They are then dispersed to eliminate pathogens.
