Answer:
Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.
Answer:
mass and distance
Explanation:
As the two objects get further away, the distance between them increase and the strength of the gravitational force decreases. If the distances decreases, the force will increase. The bigger the object, the greater the force.
The sub units that make up Macromolecules are proteins, lipids, nucleic acids, and carbohydrates.
Answer:
The correct option is C: "Oxygen levels would be higher, but carbon dioxide levels would be the same".
Explanation:
The sealed aquarium is paced near a window which means they have access to sunlight, and hence, can photosynthesize. As the plants use up carbon dioxide during the day and give out oxygen during this process, they also respire during the night, a product of which is carbon dioxide. This is why the levels of carbon dioxide will remain the same and level of oxygen will rise because they are photosynthesizing for a longer period during the day than they are respiring during the night.
Hope that answers the question, have a great day!
