Answer:
D. The rock that formed from lava would have smaller crystals than the rock that formed from magma.
Explanation:
The volcanic rocks, effusive or, more rarely, extrusive are those igneous rocks that were formed by the cooling of lava on the earth's surface1 or magma (mass of underground molten matter) at shallow depths.
The rapid cooling of magma or lava that turns into volcanic rock causes many small crystals, also called microcrystals or fine grains, to form on these rocks. Rapid cooling can also form volcanic rocks composed entirely or partially of glass.3 The most common volcanic rocks on Earth are basalt followed by andesite, while other volcanic rocks are rhyolite, dacite and trachyte to mention a few. .
Volcanic rocks constitute a small part of the rocks that originate from magma. It is estimated that during the Cenozoic an annual average of 3.7 to 4.1 km³ of volcanic rocks have been generated on Earth, a much smaller amount than the 22.1 to 29.5 km³ of plutonic rocks that are believed to have formed on average annually in the same period of time. weather.

which of the following is the best definition of an enzyme?
A. a molecule that carries genetic information
B. the specific molecule that binds to a catalyst
C. a long chain of amino acids
D. a protein catalyst in a living organism
D. A protein catalyst in a living organism
An enzyme is best defined as a protein catalyst in a living organism, speeding up specific biochemical reactions by lowering activation energy. They work through highly specific active sites and are essential for life's processes.
Explanation:The best definition of an enzyme is D. a protein catalyst in a living organism. An enzyme is a substance produced by a living organism which serves as a catalyst to accelerate specific biochemical reactions. These reactions are crucial for various biological processes and without enzymes, these reactions would proceed too slowly to sustain life. Enzymes work by lowering the activation energy required for a reaction to occur, thereby increasing the reaction rate. They bind to molecules called substrates, forming an enzyme-substrate complex, and facilitate the conversion of substrates into different molecules, the products of the reaction.
Enzymes are incredibly specific, meaning each type of enzyme typically catalyzes only one kind of biochemical reaction. The region where the enzyme binds to the substrate is known as the active site, and the fitness of this binding is often described by the induced fit model, suggesting that the active site adapts to snugly fit the substrate upon binding.

At the complete end of cellular respiration, how many molecules of ATP are produced
Answer:
38 ATP
Explanation:
On complete oxidation of one molecule of glucose yields 38 ATP. Break up of energy production is given below:
During glycolysis 2 ATP and 2 NADH is produced. During formation of Acetyl CoA, 2 NADH is produced. During Citric Acid Cycle, 2 ATP, 6 NADH, 2 FADH₂ are produced.Finally during Electron transport chain, reduced coenzymes NADH and FADH₂ oxidised to release ATP. Each NADH produce 3ATP and each FADH₂ produces 2 ATP. Altogether 10 NADH is produced during entire process of cellular respiration which yield 30 ATP and 2 FADH₂ yields 4 ATP. Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.
The number of ATP molecules produced at the complete end of cellular respiration is 38. One glucose can produce 38 molecules of ATP after glycolysis, kreb's cycle, and oxidative phosphorylation.
The process of turning biological energy from food into the chemical molecule adenosine triphosphate (ATP) is known as cellular respiration. Cellular respiration is a set of metabolic processes that take place inside the cells. The main energy currency of the cell is ATP.
Cellular respiration involves three main stages that is glycolysis, the Krebs cycle, and oxidative phosphorylation.
Glycolysis is the conversion of the glucose into two molecule of pyruvate. In Krebs cycle, pyruvate is further broken down and NADH and FADH2 molecules are produced with release of carbon dioxide, NADH and FADH2 are used in oxidative phosphorylation to produce ATP.
One molecule of glucose release up to 38 ATP molecules in total. Of these, 34 are formed by oxidative phosphorylation, 2 are produced by the Krebs cycle, and 2 are produced during glycolysis.
Therefore, 38 ATP molecules are produced after completion of cellular respiration.

Explanation: according to google
Final answer:
Deep currents in the ocean are caused by variations in water density due to temperature and salinity differences; this process is known as thermohaline circulation.
Explanation:
The question pertains to oceanic phenomena. The correct answer is B. Deep currents. Deep ocean currents are driven by variations in water density, which are typically caused by differences in temperature and salinity, a process known as thermohaline circulation. Unlike surface currents, which are primarily driven by wind, deep currents are a key component of the global conveyor belt, moving water masses through the deep ocean basins. These density-driven currents play a crucial role in regulating the Earth's climate by redistributing heat around the planet.
Which of the following things has the most thermal energy?
A)The ocean
B)A camp fire
C A hot oven
D) A hot water bottle
Answer:
B:A camp fire
Explanation:
because camp fire have carbon and hydrogen that release huge amount of thermal energy
To determine which of the given options has the most thermal energy, we need to consider the factors contributing to the thermal energy of each item.
A) The Ocean:
The ocean is a vast body of water covering a significant portion of the Earth's surface. While it contains a massive amount of water, water has a relatively high specific heat capacity, meaning it can absorb and retain heat energy well. However, the ocean's temperature varies widely depending on location, depth, and time of year. In general, the ocean may contain a large amount of thermal energy due to its sheer volume and the energy it absorbs from the sun, but it is distributed over a vast area.
B) A Campfire:
A campfire typically generates a significant amount of thermal energy. It results from the combustion of wood or other fuel, releasing heat energy in the form of flames and radiant heat. Campfires can reach high temperatures, especially when fueled adequately, and they produce intense heat in a localized area. However, their thermal energy is limited to the amount of fuel available and the efficiency of combustion.
C) A Hot Oven:
A hot oven is designed to reach and maintain high temperatures for cooking food. Ovens can be heated to several hundred degrees Fahrenheit or more, depending on the settings. They contain heating elements or gas burners that generate heat, which is then transferred to the enclosed space inside the oven. Ovens can store a significant amount of thermal energy due to their insulation and ability to maintain high temperatures over extended periods.
D) A Hot Water Bottle:
A hot water bottle contains water heated to a desired temperature and sealed within a container, typically made of rubber or similar materials. Water has a relatively high specific heat capacity, meaning it can store a considerable amount of thermal energy. A hot water bottle can retain heat for an extended period, gradually releasing it to its surroundings.
Considering these factors, the item with the most thermal energy would likely be option C) A hot oven. Ovens are designed to reach high temperatures and can store a significant amount of thermal energy due to their insulation and ability to maintain heat over time. While a campfire may produce intense heat, its thermal energy is limited by the amount of fuel available. The ocean contains vast amounts of water, but its thermal energy is distributed over a vast area and can vary widely.
A hot water bottle can retain heat well, but its thermal energy is limited by the volume of water it contains and its initial temperature. Therefore, the hot oven is likely to have the most thermal energy among the options provided.
