Answer: The statement that best describes evolution is " It is the change in heritable traits in living populations over successive generations."
Explanation: HOPE IT HELPED :)
Answer:
C
Explanation:
When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.
If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.
In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.
Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.
The answer will be B. It is common sense
Heat can be transferred from one object to another since, If there is a temperature difference between two systems, heat will always find a way to transfer from the higher to the lower system.
Kinetic energy can be transferred from one object to another, when two objects crash. One example of kinetic energy being transferred from one object to another would be a collision of pool balls, Since one ball would hit another causing it to move. Also Kinetic Energy is, “The <u>energy</u> of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.”
And last but not least, Thermal Energy which, is often referred to as heat. The thermal energy of matter depends on how fast the atoms or molecules are moving. The faster they are moving, the more thermal energy they possess. Therefore, the temperature of the matter would be higher. Thermal energy is a form of kinetic energy. One example of Thermal energy being transferred from one object to another is, Thermal energy from a hot stove is transferred to a metal pot and causes the water molecules to move faster increasing the temperature of the water. Fun fact; Thermal Energy can be transferred in three ways known as, Conduction, Convention, Radiation.
