In a solution, particles move constantly. They collide with one another and tend to spread out randomly. As a result, the particles tend to move from an area where they are more concentrated to an area where they are less concentrated, a process known as diffusion (dih-FYOO-zhun). When the concentration of the solute is the same throughout a system, the system has reached equilibrium.
What do diffusion and equilibrium have to do with cell membranes? Suppose a substance is present in unequal concentrations on either side of a cell membrane, as shown in the figure at right. If the substance can cross the cell membrane, its particles will tend to move toward the area where it is less concentrated until equilibrium is reached. At that point, the concentration of the substance on both sides of the cell membrane will be the same.
Because diffusion depends upon random particle movements, substances diffuse across membranes without requiring the cell to use energy. Even 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.
A) Mass and Weight
That's The Correct answer
The people's way of living was i<span>nfluenced by climate, microclimate, latitude, altitude, and currents. Climate affects much of the economy of a certain community. For example, droughts could lead to millions of losses in agriculture, and rainy seasons could flourished the farming sector of the region.</span>
Answer:
The correct answer will be option- to make exact copy of the DNA and pass on to the offspring
Explanation:
DNA replication is a complex process which produces the exact copy of the DNA which gets passed on to the generations. The process requires various enzymes and gains its energy from the ATP so is known as ATP dependent mechanism.
The process has to take place before the division of genetic material during cell division cycle so it takes place during S or synthesis phase of the interphase of the cell cycle.
Since DNA replication produces exact or replicated copies of the genome in organism therefore, to make an exact copy of the DNA and pass on to the offspring is the correct answer.
In this case, we are seeing the ribosomes attached in the rough endoplasmatic reticulum, Ribosomes are those in charge of attaching amino acids, creating a polypeptide chain that will fold and generate a protein.
