(e.g. The ____ has less GtC carbon than the ______ .)

Part 2: Explain how the total amount of matter is conserved during the carbon cycle.

hint-the earth is a closed system

Answers

Answer:

Explanation:

PART 2 : The Law of Conservation of Matter states that matter cannot be created or destroyed.  The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle.

Because elements are neither created nor destroyed under normal circumstances, individual atoms that compose living organisms have long histories as they cycle through the biosphere. In this depiction, a carbon atom moves from coal buried beneath the Earth's surface to a power plant and into the atmosphere. It eventually dissolves in water and is taken up by an algal cell, where it is then consumed by a copepod.

2. How does the gametophyte obtain nutrition?

Answers

Answer:

The gametophyte is generally green and photosynthetic, and obtains water and other nutrients from the soil by direct absorption into its cells. It contains no cells specializing in the transport of water and/or nutrients (vascular tissue) and therefore cannot grow so large as to prevent contact between the soil and the majority of its cells.

Answer:

from the soil and energy.

Explanation:

During osmosis, solvent particles move from an area of ____________ concentration to an area of ____________ concentration. When there is a higher concentration of solvent particles inside the cell, most solvent particles will move ____________ the cell and the cell will ____________. When there is a higher concentration of solvent particles outside the cell, most solvent particles will move ____________ the cell and the cell will ____________.

Answers

Answer:

During osmosis, solvent particles move from an area of lower concentration to an area of higher  concentration. When there is a higher concentration of solvent particles inside the cell, most solvent particles will move  outside  the cell and the cell will smaller.  When there is a higher concentration of solvent particles outside the cell, most solvent particles will move inside the cell and the cell will larger .

Explanation:

OSMOSIS -: Osmosis is the spontaneous net migration of solvent molecules into a area of higher solute concentration through a selectively permeable membrane in the direction that appears to equalize the concentrations of the solution on both sides.  It is possible to produce osmosis to do work.

For several purposes, osmosis is essential for cells. It assists in the movement within and out of the cell of essential materials. By the mechanism of osmosis, the nutrients, water and other solutes pass in and out of the cell.  

An example of osmosis happens when a semi-permeable membrane separates a sugar solution and water at the surface. The big sugar molecules of the solution can't move into the water through the membrane. Until equilibrium is formed, at the bottom ,  small water molecules pass through the membrane.

Solvent particles move from an area of Lower concentration to

An area of Higher concentration

Most of the solvent particles will move outside of the cell and

The cell will become smaller .

Most solvent particle will move inside the cell  and

The cell will become Turgid .

Osmosis is the movement of solvent molecules from a region of lower solute concentration ( i.e. high solvent potential ) to a region of higher solute concentration through a semipermeable membrane. When the concentration inside a cell is higher than the concentration ( solvent concentration ) of the environment in which the cell is placed in, the solvent particles will move outside the cell into the environment and this will cause  the cell to experience plasmolysis ( shrinking of the cell ). while

When the solvent concentration in the cell is lower than the solvent concentration of the environment in which the cell is placed the solvent particles from the cell will move into the cell causing the cell to become turgid.

Hence we can conclude that the correct answers that fills up the missing spaces are ; Lower,  Higher, outside,  smaller,  Inside and Turgid

B. Enzymes decrease the activation energy of the reaction :)

Explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

A student wins a trophy. It is a metal cup on a black plastic base. The student cleans the trophy. She holds one of the metal handles and rubs the rest of the trophy with a dry cloth. Why the plastic base does becomes negatively charged? B) The metal cup does not become charged when she rubs the trophy. Suggest why the cup does not become charged.

Answers

Answer:

  In this given statement , the plastic base becomes negatively charged because  plastic is an insulator . And the metal cup does not become charged because  metal is a conductor.                              

Explanation:

Reason behind , why plastic base becomes negatively charged -: When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.

Reason behind , why the metal cup does not become charged -:  The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .

What do you think will happen to the convection currents in the mantle if the interior of Earth eventually cool down?

Answers

As the magma cools and solidifies, the convection currents will stop and the Earth will become geologically dead.

Explanation:
Convection currents within the Earth's mantle are caused by hot material rising upwards, cooling, then dropping back toward the core. These currents are thought to be the driving force for tectonic plate activity in the crust. The moving magma in the mantle carries the plates floating on top of it.
As a result of convection, the Earth's crust is constantly being created and destroyed. The average age of the Earth's surface is 2-2.5 billion years, which is about half the theoretical age of the Earth!
If the interior of the Earth were to cool enough for convection currents to stop, then the motion of the plates would cease, and the Earth would become geologically dead. Astronomers believe that this happened to Mars long ago.
Many of Mars's surface features suggest that at one point Mars had tectonic plate activity. Today, however, Mars is a static world and the only geologic activity is in the form of erosion and bombardment from space.
