What is the purpose of the fruit on a flowering plant?
Y_Kistochka [10]
One reason is for an animal to come along and eat it's fruit, so that it can excrete the seeds somewhere else allowing that type of flower/plant to spread over distances :)

Assignment: 01.03 Transformation of Energy
trasher [3.6K]

The energy transformations that occur in the given devices are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

<h3>What is energy transformation?</h3>

Energy transformation refers to the processes by which one form of energy is transformed into another form.

The law of conservation of energy guides the various energy transformations that occur in the universe.

The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.

The energy transformations that occur in the given device are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

In conclusion, energy transformations occur according to the law of conservation of energy.

Drag each label to the correct location on the chart. Classify each process as weathering or erosion. PLEASE HELP me (I'm stuck)
Andreas93 [3]

Lets do numbering of the labels to make labelling clear.

1. The Colorado River carves land in Arizona to form the Grand Canyon.

2. Cracks form in a sandstone wall surrounding a house.

3. A marble statue near the science museum is changing color due to rainfall.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Answer:

Weathering:

2. Cracks form in a sandstone wall surrounding a house.

3.A marble statue near the science museum is changing color due to rainfall.

Erosion:

1. The Colorado River carves land in Arizona to form the Grand Canyon.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Explanation:

Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.

So, on the basis of this difference we can classify each label to the correct location:

<u>Weathering (no movement of particles after degradation):</u>

2. Cracks in a sandstone wall of a house.

3. Changing color of marble statue due to rainfall.

<u>Erosion (Movement of particles from one place to another):</u>

1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.

4. Soil and rock pieces litter on roadways after rainstorms.

5. Changing shape of dunes in sahara desert.

What type of molecule makes up most of the cell membrane?
NikAS [45]

Answer:

Proteins and phospholipids make up most of the membrane structure. The phospholipids make the basic bag, while the proteins are found around the holes and help move molecules in and out of the cell.
