There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.

Word bank: (Thermosphere) (Aurora boreal is) ( Large-scale air turbulence and mixing at this layer) ( Stratosphere) (The coldest
Lyrx [107]
  • Thermosphere - Fourth layer of Earth's atmosphere.
  • Aurora Borealis - Ionosphere layer of thermosphere.
  • Large-scale air turbulence and mixing at this layer - Troposphere
  • Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
  • The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
  • Maximum ozone - Ozone layer in Stratosphere

Explanation:

Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.

1. Troposphere -

  • The first layer of the atmosphere.
  • Weather occurs in this layer.

2.Stratosphere -

  • The second layer of Earth's atmosphere.
  • Contains Ozone layer.

3. Mesosphere -

  • The third layer above the stratosphere.
  • Coldest layer.

4. Thermosphere -

  • The fourth layer of the atmosphere.
  • Warmest layer.
  • Ionosphere - lowest level of thermosphere above mesosphere.
  • Aurora Borealis, Northern and Southern lights are seen in this layer.
  • Exosphere - outermost layer of thermosphere.
  • Satellites are in this layer.
  • Outer space with no gravity.

What is “soil type” to an earthworm?
Evgen [1.6K]

Answer:

Abiotic factor.

Explanation:

Soil type is an abiotic factor for an earthworm. The soil type helps an earthworm to collect food and increase the population.

Sunlight, soil, water, and rocks are those abiotic factors that contribute to earthworms to obtain their food and to survive under the soil or upper side of the soil.

Like earthworms, many other organisms depend on the abiotic factors for their livelihood.
