6. Classify Earth's layers based on their physical properties. *

1 answer:

3 0

Three main layers of the earth
1. Core the innermost part
2. Mantle the middle part
3. Crust the outermost part

The special feature of the upper mantle is the asthenosphere. It is located just below the lithosphere and is made up of rock that is fluid and can move. The fluidity of these rocks powered the movement of tectonic plates on the earth's crust. Circular convection cycles in the hot, fluid upper mantle rock move the plates over the surface of the Earth.

Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain

docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.

Regulatory and basal transcription factors regulate transcription by binding to the promoter.A) True B) False

Licemer1 [7]

Answer:

False

Explanation:

In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.

There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.

Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
