You know lots of stuff like how its a chemical formula.
Answer: C. i. potential, ii. kinetic, iii. potential and kinetic
Explanation: Potential energy is the energy that is possessed or exhibited by an object or a body that is static or stable. THE FORMULA FOR POTENTIAL ENERGY IS P.E = MASS OF AN OBJECT* HEIGHT * FORCE OF GRAVITY
Kinetic energy is the energy of an object or a body that is in motion or it is moving from one point to another.
THE FORMULAR FOR KINETIC ENERGY IS 1/2*MASS OF AN OBJECT *VELOCITY OF THE OBJECT SQUARE.
Answer:
Sodium ions are pumped from a region of lower concentration to a region of higher concentration in the nerve cells of humans
Explanation:
Active transport is a kind of transport in which substances or molecules are moved from a region where they are in low concentration to a region where they are in high concentration. Active transport occurs against concentration gradient, hence, energy input in form of ATP is required.
Based on this description, the option that best ilustrates active transport is when: Sodium ions are pumped from a region of lower concentration to a region of higher concentration in the nerve cells of humans. The process will require energy to occur since sodium ions are pumped against concentration gradient.
<span>The correct answer is radial symmetry, meaning that it they have a central axis like sponges and jellyfish do, and they are mostly sexual but there are some asexual species. In addition, animals like jellyfish which belong to cnidaria are coelomates. The phyllum is too big for it to be precisely defined under these categories what belongs where.</span><span />
