______ 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.

Over years of selective breeding, French bulldogs have developed extremely short snouts and flat faces. These traits, although attractive to the dog owners, can make it difficult for the dogs to breathe.Which of the following processes led to the presence of these traits?
(Choice A)
A
Artificial selection
(Choice B)
B
Natural selection
(Choice C)
C
Environmental selection
(Choice D)
D
Sexual selection
Answer:
Artificial selection
Explanation:
Choice A, artificial selection, led to the presence of these traits in French bulldogs.
What is Artificial selection?Artificial selection, also known as selective breeding, is the process of breeding organisms with desirable traits in order to produce offspring with those traits. In the case of French bulldogs, humans selectively bred dogs with shorter snouts and flatter faces in order to create a breed that was aesthetically pleasing. However, these traits also led to health problems such as difficulty breathing.
Natural selection, on the other hand, is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of those traits in a population.
Environmental selection refers to the process by which the environment favors certain traits over others. Sexual selection is a type of natural selection that occurs when individuals with certain traits are more likely to attract mates and reproduce.
In the case of French bulldogs, these traits were not naturally selected for based on survival advantages, nor were they the result of environmental or sexual selection. Rather, they were artificially selected for by humans, leading to unintended consequences for the dogs' health.

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.

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.

is formed when one or more than one atom bonds to another atom.
Explanation:A special case of polar forces occurs in what is called the hydrogen bond. In many situations, when hydrogen forms a covalent bond with another atom , electrons move toward that atom, and the hydrogen acquires a slight positive charge. The hydrogen, in turn, attracts another atom, thereby forming a kind of bridge between the two.

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.
