Answer:
By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different materials and placed in the freezer
Explanation:
Experimental design
Materials given: freezer, a thermometer, samples of materials
setup:
1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.
2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.
3. after the time, the final temperature on the thermometer is recorded.
Result interpretation
The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat
independent variables: type of material used
dependent variables: temperature on the thermometer
control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.
Answer:
atp
Explanation:
ATP is composed of ribose, a five-carbon sugar, three phosphate groups, and adenine , a nitrogen-containing compound (also known as a nitrogenous base). What class of organic macromolecules is composed of monomers similar to ATP? ATP directly or indirectly delivers energy to almost all metabolic pathways.
New cells are spontaneously created from existing cells
They leave no record of their existence because it's rare that fossils form. You need the right conditions in which the animal's remains are covered in silt, dirt, and rock layers in order for a fossil to form and therefore preserve the animal's remains in rocks. Otherwise, the animal's remains will be eaten by other animals or eventually rot away.
Answer:
"When El Niño occurs every three to seven years, a mass of warm Pacific water that is usually pushed westward by trade winds, <em>surges back eastward toward South America".</em>
Explanation:
Under normal conditions, warm water and air masses move westward, which makes it possible for cold water to ascend in a process known as <u>upwelling</u>. This upwelling occurs in South America´s coasts, providing nutrients from the bottom to the animals, especially fishes -which favors fisheries activities-. Humidity goes straight to the west precipitating in Indochina and North Australia, among other places.
Under <u>El Niño conditions</u>, a tropical stream, that is normally small, acquires strength while the opposite streams debilitate. This <u>avoids warm water to go westward, remaining in South America´s coasts</u>, which produces unusual precipitations in Chile´s coasts -followed by floral bloom in Atacama desert-, and fewer precipitations in Eastsouth Asia and North Australia. Upwelling does not occur, so there is a fishery crisis because nutrients from the bottom do no ascend and fish populations remain equal or smaller.
