Answer:
Tubulin, actin.
Explanation:
Cytoskeleton may be defined as the network of protein filaments present in the cytosol of the organism. Cytoskeleton helps in the movement of cell organelle and their interaction with other organelles.
MreB protein is a cytoskeletal protein present in bacteria that control the width shape of the rod shaped bacteria. The MreB protein is homologous to the actin protein of bacteria because of the similarity in their peptide sequence and tertiary structure. FtsZ is the cytoskeletal protein present in bacteria that helps in the cell division. The FtsZ protein is homologous to tubulin protein of eukaryotes because of similarity in their function.
Thus, the answer is tubulin, actin.
Answer:
Option A, oxygen in the atmosphere
Explanation:
The highest level of oxygen reached during this phase of the geological cycle of earth. The oxygen level in Carboniferous period accounted for 35% as compared to 21% of oxygen in the atmosphere in present time.
Due to high oxygen content, the giant and wide varieties of terrestrial animal and plant species evolved. For example – size of insects and carwlies increased, plant became extremely giant, increase in number of tree ferns etc.
Answer:
Rocks form through a variety of processes. These processes require energy. The best description of how the energy of Earth's interior contributes to the formation of rocks on its surface is the energy in the earth's interior melts rock, creating magma which cools back into rock when it reaches the surface
Correct Answer : Option A
Explanation:
The energy in the earth's interior melts rock, creating magma which cools back into rock when it reaches the surface is the formation of rock of igneous type and is processed via the cycle which is rock cycle. The rocks are being pushed deeper into interior of the Earth, where it melts down into magma.
When these magma are no longer in state to remain liquid, they start cooling and thereby, gets solidify as well. This solidification causes the formation of the rock again, which is of igneous type rock.
