Answer:
It is possible to produce an offspring from a zebra mating with a donkey. Indeed, in Florence, Italy, a male zebra mated with a female donkey and produced a striped mule.
Animal cells communicate via their extracellular matrices and are connected to each other via tight junctions, desmosomes, and gap junctions
" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.
<h3>
What is Kinetic energy?</h3>
- Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
- An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
- The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

Answer:
Concentration gradient
Explanation:
Concentration gradient of the ions across the membrane generates the membrane resting potential.
Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
