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.

Apoptosis involves all but which of the following?
LenaWriter [7]

Answer:

Apoptosis does not involve:

c. lysis of the cell

Explanation:

Apoptosis is a programmed cell death that occurs under normal physiological conditions and in a controlled manner. Normally seen in cell turnover, embryogenesis, also involved in processes of immune, nervous and endocrine systems.

The main morphological and biochemical changes seen during the apoptosis are the fragmentation of DNA by endonucleases, nuclear, chromatin and cytoplasmatic condensation, apoptotic bodies formation (membrane bound-vesicles form of cell parts) and the phagocytosis (digestion) of those bodies by the scavenger cells.

Apoptosis is regulated by cell- signaling pathways, the caspases, a family of cysteine proteases, are the ones involved in the process.

In the process there is no lysis of the cell as this could lead to a inflammatory response (just happens in necrosis) which would affect contiguous cells, and will involve immune cells. In apoptosis there is just a membrane blebbing, but it does not loss its integrity.
