An organelle that releases energy through a common biological process that is common to eukaryotes is the mitochondrion, this would be cellular respiration.
made of three layers
has a terry layer
has a solid outer layer
Explanation:
The mantle is mechanically made up of three layers.
The rigid part that joins with the lithosphere, asthenosphere and the inner mesosphere. The asthenosphere molten, weak and relatively flows. Part of the mantle in conjunction with the crust makes up a lithospheric plate on the earth crust.
The lower layer is the is the mesosphere or middle layer. It is a solid rigid ball that is highly dense. Below this layer is the outer core.
- The mantle is made up of ferro-magnesian minerals.
- Density and pressure here increases with depth in the mantle

Answer:
The correct answer will be option-A.
Explanation:
The lac repressor is a protein produced by the regulator gene present in the lac operon called lacI gene. The repressor proteins bind to a DNA sequence called the operator and block the site for binding of RNA polymerase, thus shuts off the transcription when lactose is absent.
Lac operon is a homotetramer made of two dimers with two alpha-helix bundles which bind to different regions of the operator. The binding of the allolactose to protein causes conformation change in the protein due to which separates the binding helix of the DNA and inhibit the association of the protein to DNA.
Thus, option-A is the correct answer.
