Answer:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

These types of cells are found in the reproductive organs and are called _____ cells.
A. Gamete
B. Body
An organism's reproductive cells are called gametes. They are also known as "sex cells." Therefore, option (A) is correct.
A gamete, sex, or reproductive cell with just one pair of chromosomes that are different from one another, or with only 50 percent of the genetic material required to make a whole creature (i.e., haploid). Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.
In creatures that reproduce sexually, a gamete is a haploid cell that combines with another haploid cell during fertilization. These reproductive cells, are crucial to the process because they aid in the creation of the zygote, a brand-new cell.
Thus, option (A) is correct.

Available energy increases at it is transferred from one organism to another in a food chain true or false
Answer:
"Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up." By the way this is from the internet but from what I read it should be false mark brainllest if you want.

9. Which statement accurately describes the graph?
A. Reaction 2 occurs faster than Reaction 3 because Reaction 2 requires more energy than Reaction 3.
B. Product B contains more energy at the end of the reaction than reactant A has at the beginning of the
reaction.
C. Reactant A contains more energy at the beginning of the reaction than product C has at the end of the
reaction.
D. The data plotted for Reaction 2 and Reaction 3 indicate a difference in the activation energy of these
reactions.
Answer:
D
Explanation:
Each reaction starts at 0J (i.e. no energy). So, you can eliminate C. and B. simply by comparing the start point (A) to those end points.
Product B does not contain more energy than reactant A because the line falls below the axis (falls below zero). (You can apply this same logic for question C)
A. is incorrect because all the reactions appear to be occurring on the same time scale.
D. is the best answer because activation energy is best identifiable difference between these three reactions. The 'hump' in the graph represents the activation energy. The higher the hump, the higher the energy.
Let me know if anything sounds wrong! Cheers.

Which is not a basic function of a cell?
______ breaks down fibrin and restores the fluidity of plasma.
A. Fibrogen
B. Plasminogen
C. Plasmin
D. All of the above
Answer: A. Fibrogen
Explanation: A fluid called serum (plasma minus fibrinogen and prothrombin) is squeezed from the clot. A fibrin clot is present only temporarily. As soon as blood vessel repair is initiated, an enzyme called plasmin destroys the fibrin network and restores the fluidity of the plasma.
Fibrinogen breaks down fibrin and restores the fluidity of plasma, during blood clotting. Hence, option A is correct.
What is the process of blood clotting?Coagulation is the term for the multi-step process that causes blood to clot. Blood binds securely together at the site of an injury when the entire coagulation process is functioning effectively, and bleeding ceases. When you have a bleeding issue, you can't quickly or at all form powerful clots.
Plasma-derived proteins known as blood clotting factors or coagulation factors are used in the coagulation cascade, a sophisticated chemical process. Simply put, the clotting process converts blood at the site of an injury from a liquid to a solid.
The enzyme converts the plasma protein fibrinogen, which is soluble, into fibrin, which is insoluble. Some red blood cells get caught in a net made of fibrin, which is sticky and creates lengthy threads. This creates blood clots. Therefore, option A is correct.

Tectonic plates move slowly but get stuck due to friction over the edge, creating stress, when it is overcome the friction earthquake occurs, hence option c is correct.
What is an earthquake?The majority of earthquakes occur along fault zones, which are areas where tectonic plates—giant rock slabs that make up the Earth's top layer—collide or move against one other.
Earthquakes are often produced by subsurface rock abruptly breaking and fast moving along a fault, when tectonic plates stress is over the friction it creates earthquakes.
Over 80% of big earthquakes occur near the Pacific Ocean's equator, in a region known as the "Ring of Fire," where the Pacific plate is being subducted beneath the surrounding plates.
Therefore due to the motion of the tectonic plate earthquake occurs because of streess at the edge of the plates, hence option c is correct.

Describe the lithosphere and its role in plate tectonics.
The lithosphere,which is the rigid outermost shell of the planet(the crust,and upper mantle),is broken into tectonic plates.The earth's lithosphere is composed of seven or eight major plates(depending on how they are defined)and many minor plates.In this way,the total surface of the lithosphere remain,the same.
The upper mantle, crust, and lithosphere, the planet's solid outermost shell, are divided into tectonic plates. Depending on how they are classified, the lithosphere of the earth is made up of seven or eight major plates as well as several lesser plates. The lithosphere's overall surface remains constant in this fashion.
What lithosphere and its role in plate tectonics?In terms of plate tectonics, the lithosphere serves as the “plate.” Seismic waves enter the warm, plastic Asthenosphere at a slower speed in this "low-velocity” seismic zone, which denotes the base of the lithospheres. With a property known as plastic behavior, the Asthenosphere (weak sphere) is a component of the flowing Mantle.
Therefore, In plate tectonics, the Earth's lithosphere, which is composed of the crust and upper mantle, is divided into sizable rocky plates. These plates are situated on top of the asthenosphere, a rock layer that is still partially molten.

When the concentration of solute is the same throughout a system, the system has reached ....?
Answer:
A,B
when the concentration of the solute is the SAME throughout a system, the system has reached (equilibrium).
particles tend to move from an area where they are MORE concentrated to an area where they are LESS concentrated, is a process of (diffusion).
Explanation:
When the concentration of solute is the same throughout a system, the system has reached equilibrium.
What is an equilibrium?A concentration gradient exists across the cell membrane initially and we say that equilibrium has reached when there is an equal amount of the substance on both sides of the membrane.
Isotonic solution is a solution that has the same solute concentration as that of another solution. There is no movement of water particles and the overall concentration on both sides of the cell membrane is constant.
The isotonic solution helps the cells to move water and nutrients in and out of the cells that is essential for blood cells in delivering oxygen and other nutrients to other parts of the body.
Diffusion of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration till equilibrium is reached is called osmosis.
