Answer: Symbiotic Relationship
Both fig trees and fig wasps are important for each others survival.
Explanation: The fig provides a joke for the wasps and the wasps provide pollen that the fig needs for the fruit to ripen.
It basically begins when a female fig wasp enters the fig and lays eggs ,they pollinate the fig with pollen that they had collected in their pouches after mating ,when the wasp enters the fig its wings and parts of antennae may get broken because of the small opening in the fruit ,the wasp completes it's task and never leave the fruit after.
Independent Variable: flight
Dependent Variable: size of parachutes
Controlled Variables: precipitation, wind speed, person using parachute (weight), and the shape of the parachute.
The question is slightly broad; it does not specify whether the experiment focuses on the quality of the flight (stability in the air), speed of descent, or the distance it can travel. However, this is what I have come up with.
D, because flatworm don't use cellular respiration nor do they use photosynthesis or make their own food neither do humans, which leaves the D, which is true. :)
I think to seal the sucking chest wound, we would put something plastic e.g a plastic wrap (preferably) sterile or at least clean) over the hole and tape it down. One can use the first aid device called a chest seal for this. In addition, another trick is to use the packaging that sterile dressings come in.
