Answer:
The Answer is 'D'
Explanation:
The diagram on the down side shows the behavior of the particles of a liquid so I suppose it is the ocean. While the top diagram shows the behavior of the particles of a gas so I am sure it's the air. Therefore I chose the last diagram because it describes exactly how you wanted in the question, which is the Ocean's water evaporating to become gas or the 'air' as we say

Answer: Length and width
Explanation:
Answer:
Length and width
Explanation:
Energy can be neither created nor destroyed. This fact means that even though energy sources can be depleted (used up), the energy in them is not destroyed. Instead, it is transformed to other forms of energy. And almost all energy resources here on Earth can have their energy traced back to the Sun’s gravitational or light energy.
Electricity is often thought of as a secondary source of energy because it must be gained by transforming some other kind of energy (a primary source). Think about where the electricity generated by a wind turbine comes from. Describe the path that wind energy takes from the Sun’s light to electricity.

How many protons, neutrons, and electrons does potassium's neutral atom have?
Answer:
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.
Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
Explanation:
Answer:
Number of Protons 19
Explanation:
Number of Neutrons 20
Number of Electrons 19

What is the relationship between parent cells and daughter cells.
Answer:
Explanation:In particular, eukaryotic cells divide using the processes of mitosis and meiosis. Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
A parent cell is the cell that divides during cell division to produce two daughter cells. The two daughter cells produced during mitosis share the same genetic makeup as the parent cell. In meiosis, the daughter cells have half as many chromosomes as the parent cell and a distinct genetic makeup.
What is parent cell ?A parent cell that is a progenitor of other cells or the first in a line of growing cells, as well as a cell that divides to produce two or more daughter cells.
The cell that divides into two daughter cells during cell division is referred to as the mother or parent cell. The mother cell's genetic makeup is carried over into the two daughter cells created during mitosis.
An organism's reproductive cells are called gametes. They are additionally known as sex cells. Male gametes are referred to as sperm, whereas female gametes are referred to as ova or egg cells. Each haploid cell that makes up a gamete has one copy of each chromosome.
Thus, A parent cell is the cell that divides during cell division to produce two daughter cells.
