Answer:
E. bind to troponin which moves the tropomyosin
Explanation:
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction
Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
Answer:
I'm not sure exactly what your supposed to do but a,b and c are all correct but d is false.
Hello,
The answer is "natural selection is how animals, or plants survive or adapt to their environment".
Reason:
Natural selection is how animals, or<span> plants survive or adapt to their environment this idea came up by Charles Darwin and how he examined the birds beaks which means he came up with the theory of evolution which means that animals evolve to a different type of that species to adapt to there environment with is natural selection.
If you need anymore help feel free to ask me!
Hope this helps!
