proteins
lipids
Answer:
protein
Explanation:
because carbohydrate ..nucleic acids protein
Biological molecules are large molecules made of various elements and compounds linked together. Proteins are composed of C, H, O, N, and S. Thus, option C is correct.
What are proteins?Proteins are considered macromolecules that are large in size and are polymers composed of various units of amino acids linked together by peptide bonds. They are involved in various activities and structural functions in the body.
The chains of various amino acids linked together make the protein molecule. The amino acids involved in the structure are composed of various elements that include, hydrogen, carbon, oxygen, nitrogen, and sulfur in various combinations. The amino acids contain amine, carboxylic acid, and other variable groups.
Therefore, option C. proteins are made of monomers of amino acids.

Metamorphic rocks are common when two continental plates collide because There is a lot of stress when enormous slabs of crust push together Sediment buries rocks to increase pressure O Magma bodies are common because there is a lot of melting O All of these
Answer: Metamorphic rock, estimated to be as old as 3.8 billion years, located near Isua at Qorqut Sound, Greenland.In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened. A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.
The conditions required to form a metamorphic rock are very specific. The existing rock must be exposed to high heat, high pressure, or to a hot, mineral-rich fluid. Usually, all three of these circumstances are met. These conditions are most often found either deep in Earth’s crust or at plate boundaries where tectonic plates collide. In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock.

why is the digestion of starch to glucose necessary
Answer: The fundamental sugar unit for carbs is usually glucose. To address your question, starch digestion is required because enzymes and transport molecules require tiny, regular molecules to work with, and glucose is the foundation of most carbohydrate metabolism.
Explanation:
Answer:
The molecule of starch is too large and complex to enter a cell and therefore, it cannot be ingested directly. It is important to break down the bigger molecules of starch into smaller and simpler molecules of glucose so as to perform the process of glycolysis.
Explanation:
The process of glycolysis happens at a cellular level where glucose molecules are further broken down and utilized as energy to carry on various other cellular processes. The process of glycolysis happens in two stages namely:Energy requiring stage:Step 1: Glucose phosphorylation where a molecule of phosphorus is added to the glucose ring.Step 2: Energy releasing phase where the molecule of glucose-6-phosphate is converted to fructose-6-phosphate. Step 3: involves the phosphofructokinase reaction where fructose-6-phosphate is converted into fructose1,6-biphosphate.Step 4: involves an enzyme aldolase which converts the FBP into 23 carbon isomers.Step 5: involves the formation of glyceraldehyde-3-phosphate.Energy releasing stage: It breaks down glyceraldehyde-3-phosphate to pyruvate releasing 4 ATP and 2 NADP for cellular processes.For more information:

Which example(s) of cell transport do/does not require chemical energy?
A.
Drops of blue food coloring are placed in water and spread throughout the water, turning it blue.
B.
A potato slice is placed in water and water molecules from inside the potato move into the surrounding water.
C.
both A and B
D.
neither A nor B
Answer:
C
Explanation:
Because osmosis(B) this is where water moves from a high concentration to a low concentration across a partially permiable membrane( No energy required). Whereas in diffusion (a) this is the net movement of particles from a region of a high concentration to a region of a low concentration. This stops when the region is evenly spread. (No energy is required)
The cell transport which takes place in food coloring, potato slice is concentration gradient. This type of cell transport does not need energy. Thus, the correct option is C.
What is Cell transport?
Cell transport is the transport of molecules through the cell membrane. Transport of substances through the membrane takes place through osmosis and diffusion.
The diffusion of substances can be active or passive on the basis of requirement of energy. The passive mode of transport does not require energy as the movement of substances occurs down the concentration gradient from high concentration to low concentration. Whereas, in active transport energy is required in the form of ATP as the transport occurs against the concentration gradient from low concentration to high concentration.
Therefore, the correct option is C.

how does the colour of star help to find its age
Answer:
As stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit. Thus, younger stars can appear bluer while older ones appear more red, and in this way, a star's color can tell us something about that star's age.

Help please! Q: Location Three: Select three events that you predict will be observed. If I explore two continental plates at a transform boundary, then I will observe:
A: earthquakes
B: faults
C: ocean formation
D: mountains
E: volcanoes
F: island chains
G: seafloor spreading
Answer:
Earthquakes, Faults, and Island chains.
Explanation:
There are three types of plate boundary such as Constructive, destructive and transform plate boundary. The primary landform in the Transform boundary are faults which is caused by the Earthquakes. Many transform boundary landforms are in the ocean floor which is responsible for the island formation. Fault is found due to the two process such as Ridge push and ridge pull. Transform boundary neither creates and nor destroys any land in the region.
