Answer:
<h2>A shadow is an area where direct light from a relatively small source is blocked by some opaque object. If the source is genuinely the only light around, the shadow will be absolutely black, and will have no colour.</h2>
Answer:
<u>The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.</u>
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.
Answer:
c. protein from RNA
Explanation:
Translation is a process that occurs in the ribosomes where tRNA is used to read the mRNA strand and translate the codons into complementary amino acids.
Osmosis is the controlled movement of free water molecules though a selectively semi-permeable membrane from a region of high water concentration to a region of low water concentration. Using this definition osmosis will be the movement of water molecules.
