Answer:
Evolution.
Explanation:
The unique method of locomotion in octopus has been utilized by successive generations of octopus through the process of evolution. Evolution is defined as the change in the characteristics of a species over several generations. This type of behaviour is attain by octopus in order to save itself from its predators such as shark so we can say that this unique method of movement is used by octopus to save itself from the predators leads to evolution in the octopus.
Answer:
Root anchor them in the ground and absorb water for the plant. Woody stem provides support to the plant and connect the roots and leaves. Leaves capture the sun's energy and use it to make food through the process of photosynthesis. Flowers contain the reproductive parts of the plant. fruite protect and help spread the seeds.
Explanation:
The dimensions of the room is not given. Lets assume a value and calculate BTU accordingly.
Answer and Explanation:
BTU, or British Thermal Unit, is defined as the amount of heat required to raise the temperature of 1 pound of water by 1° F.
In other words,BTU's measures the amount of heat an AC (or any other cooling unit) can remove from a room per hour. Higher the BTU, the more powerful the cooling.
Calculation:
Lets assume that a room is 10 feet wide and 14 feet long.
Calculate the size of the room by multiplying the height of the room with its width:
size of the room= 10 × 14
= 140 square feet
Then multiply the size of the room that you obtained in step 1 with 20 BTU per square foot, in order to get the minimum BTU's required for AC to cool a room,
140 × 20= 2800
2800 BTU cooling capacity is required.
