Answer: sorry need picture
Explanation: show picture in order to tell you
Answer:
Active
Explanation:
Endocytosis is a type of active transport where large molecules or even cells are moved inside the cell.
Answer:
remains constant
Explanation:
i believe it is remains constant because we would just randomly float up and down sometimes
The correct answer is B. Delta, Deltas can only be formed when sediments are being carried by the waterway (stream,river). As the water flows and meets another body of water, sediments land and piles up making beds. As the water flows through shallow areas, it forms triangular shaped areas of water where the stream meets a larger area of water.
Answer:
The correct option is B. Activation energy
Explanation:
The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.
For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.
The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
