Answer:
In primary active transport, the energy is gotten directly from the breakdown of ATP. In the secondary active transport, the energy is gotten secondarily from energy that has been stored in the form of ionic concentration differences between the two sides of a membrane
One of the reasons the plasma membrane can have<span> selective permeability</span><span> it's because it's composed by a bi-layer of phospholipids.
The interaction between them and other molecules will influence how these molecules will cross the membrane. If the molecule it's </span>hydrophobic it can easily cross, if it's polar molecules and ions( hydrophilic), they cannot cross easily.
The temperature stability of earth’s atmosphere is mostly due to "b. the rotation of earth about its axis," which is the reason why we have seasons. Water also plays a role.
B and C are the same but the best answer is C
<h2>Answer:</h2>
Baseball would travel father than the basketball because it has less mass than the basketball.
<h2>Explanation:</h2>
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. So the Baseball would travel father than the basketball.
