Answer: molecules move, but there is no net movement in a particular direction.
Option A is correct.
Explanation:
When equilibrium is reached, particles of a solution will continue to move across the membrane in both directions. However, because almost equal numbers of particles move in each direction, there is no further change in concentration. Equilibrium is reached in a system when the concentration of a solute is equal on both sides of the membrane.
Answer:
Thermosphere, mesosphere , stratosphere and troposphere.
Explanation:
Thermosphere and exosphere are the layer that starts above 140 kilometers. In these layers of atmosphere, the temperature increases from colder to warmer and satellite travels in these layers of atmosphere. Mesosphere layer is present between 50 to 85 km while on the other hand, stratosphere is present between from 10 to 50 km and in this layer, aeroplane travels. Troposphere layer is present from the earth surface to 10 km and the temperature is decreases from warmer to colder. Hydrogen ozone is also present in this layer in very small amount.
Answer:
DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.
DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.
DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
