Answer:
5) The different elements present in the different igneous compositions will form different minerals. Rocks with high amounts of iron (Fe) tend to form minerals that are dark in color (such as olivine and pyroxene). As result, mafic rocks tend to be dark in color and felsic rocks tend to be lighter in color.
6) There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.
Explanation:
When the upper water layers warm in the summer months, they become separated from deep water by a transition zone known as a thermocline. In a thermocline, the temperature decreases rapidly with small increases in depth. This phenomenon linking temperature change with depth is called temperature stratification.
Answer:
The correct answer will be option-1. Skeletal muscle cells use creatine phosphate instead of ATP to do work
Explanation:
Skeletal muscles are one of the three types of muscle cells present in the organisms which control the voluntary movements of the body as they are attached to the skeletal system of the body.
The cells of the skeletal muscle are characterized by the many nuclei, presence of the myoglobin, glycosomes (stored glycogen) and the structure of the muscle cells are transversed by the Transverse tubules or T-tubules which help transmit the electrical signals to the muscle cells.
The cells cause movements utilizing the ATP as a source of energy which helps form and breakdown the cross-bridge.
Thus, the selected option is the correct answer.
Answer:
Topoisomerase
Explanation:
Topoisomerase is an enzyme that is involved in the unwinding of Deoxyribonucleic acid (DNA). They are involved in double stranded DNA and they help to relieve the making of supercoils.
Topoisomerase play an important role during DNA replication, as the prevent the the twisting of the DNA double helix ahead of the replication fork. In other words, they ensure that the DNA open up for unwinding without being tightly wound.
