The correct option is A i.e. Toxic.
Oil leaks from cars contribute to non-point source pollution, which contaminates waterways with toxic substances. This can harm aquatic ecosystems and degrade water quality.
When cars age or are poorly maintained, they can leak oil onto roadways and parking lots. This oil is washed into the nearest waterway with rainfall, causing a type of pollution known as non-point source pollution. Non-point source pollution occurs when contaminants such as oil, gasoline, and other automotive fluids are washed off surfaces by rainwater and flow into water bodies like rivers, lakes, and oceans.This type of pollution is harmful because it can introduce toxic substances into aquatic ecosystems, affecting the health of both the environment and human populations. Key contaminants from road runoff include not only oil and gas but also metals and organic waste, all of which can degrade water quality and impact water treatment facilities. To address this issue, it is important to properly dispose of motor oil and other chemicals, fix leaking vehicles promptly, and use fewer chemicals in other land-based activities. By taking these steps, we can reduce the contamination of our water supplies and protect the environment.The complete question is:

Shallow water – Some tiny fish and coral only live in the shallow waters close to land. While Deep water – Big and even gigantic creatures can live deep in the waters of the oceans. Some of the strangest creatures in the world live right at the bottom of the sea. Ocean ecosystems are relatively contained, although they, like freshwater ecosystems, also include certain birds that hunt for fish and insects close to the ocean’s surface. There are different sorts of ocean ecosystems.

What would happen if all receptor proteins were removed from the membranes of all liver cells?
Removing all receptor proteins from liver cells would severely impair cellular communication and function, leading to metabolic dysfunction. A cell with unbalanced exocytosis and endocytosis would have an expanding plasma membrane, potentially causing dysfunction or lysis.
If all receptor proteins were removed from the membranes of all liver cells, it would have a disastrous effect on cellular communication and function. Receptor proteins are responsible for receiving signals from outside the cell and triggering a cascade of events inside the cell that result in specific cellular responses. Without these receptors, liver cells would be unable to process signals from hormones, nutrients, and other signaling molecules, leading to a breakdown in the regulation of metabolism, detoxification processes, and other vital functions. The cells would be unable to adapt to changing conditions in the body, which could result in widespread metabolic dysfunction and disease.
Regarding the cell performing exocytosis with minimal endocytosis, the consequence would be an increase in the size of the plasma membrane over time. This is because exocytosis adds membrane material to the plasma membrane, whereas endocytosis normally retrieves membrane material. A significant imbalance between these processes would disrupt membrane homeostasis, potentially leading to cell dysfunction or even lysis (rupture).
Lastly, if the intracellular domain of a cell-surface receptor was switched with the domain from another receptor, the signaling specificity and cellular response could be severely affected. The intracellular domain of a receptor is responsible for initiating specific intracellular signaling pathways. A switched domain might activate inappropriate pathways, fail to activate necessary pathways, or cause unpredictable responses, possibly resulting in dysfunction or disease.

What is activation energy?
the energy needed to get a reaction started
the energy stored in the bonds of a reaction’s enzyme
the energy absorbed by the bonds that form in a reaction
the heat energy given off by a reaction
Answer:The energy needed to get a reaction started.
Explanation:
Activation energy is the minimum amount of energy needed to initiate a chemical reaction. It's the force necessary to break initial bonds and allow a reaction between reactants, transformation into products. Therefore, option a. is the correct answer.
Activation energy is the energy required to initiate a chemical reaction and start the process of breaking and forming chemical bonds in reactant molecules to produce products. Here's an explanation of what activation energy is and how it works:
Energy Barrier: In any chemical reaction, reactant molecules must first overcome an energy barrier, known as the activation energy barrier, to transition from their initial state to the state where new chemical bonds are formed in the products.Breaking Bonds: Before new bonds can form in the products, the existing chemical bonds in the reactant molecules must be broken. Breaking these bonds requires energy because chemical bonds hold atoms together, and breaking them apart involves overcoming the electrostatic forces that hold the atoms together.Activation Energy: Activation energy is the minimum amount of energy needed for these initial bond-breaking processes to occur. It acts as a barrier that reactant molecules must surpass to proceed with the reaction.Facilitating Reaction: Enzymes and other catalysts play a crucial role in lowering the activation energy required for a reaction. They do so by providing an alternative reaction pathway that has a lower activation energy than the uncatalyzed reaction. This allows reactions to occur more readily and at lower temperatures in biological systems.Endothermic and Exothermic: Activation energy can vary depending on the specific reaction. For endothermic reactions (absorbing heat), activation energy represents the energy required to absorb heat and break bonds. For exothermic reactions (releasing heat), activation energy represents the energy needed to initiate the reaction and release heat during bond formation.In summary, activation energy is the energy "hurdle" that reactant molecules must overcome to initiate a chemical reaction. It represents the energy required to break existing bonds in reactants, allowing new bonds to form in the products. Catalysts, like enzymes, lower this energy barrier, making reactions more efficient and feasible under physiological conditions.
Therefore, option a. is the correct answer.

Which type of rock is formed from cooling molten rock?
A.igneous
B.magma
C.metamorphic
D.sedimentary
Igneous rocks are formed from the cooling and solidification of molten rock, either as magma below the surface resulting in a coarse texture, or as lava on the surface creating a fine-grained texture.
Explanation:The type of rock formed from cooling molten rock is igneous rock. Igneous rocks are one of the three main types of rocks found on Earth, the others being sedimentary and metamorphic rocks. These rocks form as magma (below the Earth's surface) or lava (at the Earth's surface) cools and solidifies. For instance, when magma cools slowly underground, the resulting igneous rocks, such as granite, are considered intrusive or plutonic and have a coarse-grained texture. Conversely, when lava cools rapidly on the Earth's surface, it forms extrusive or volcanic igneous rocks like basalt, which tend to have a finer-grained texture.
Igneous rocks are formed from cooling molten rock. When magma or lava cools and solidifies, minerals start to crystallize and interlock with each other, forming igneous rocks. Igneous rocks can have different textures and compositions depending on the cooling rate of the magma or lava.
