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.

Can someone please help me with this it's for a grade.
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

What are three ways that synthetic materials benefit human society?
Answer:
The benefits in synthetics are many, they have properties that we can't find in nature, they allow us to make things stronger, lighter, more fuel-efficient, shiner, longer lasting. And at the same time, we do add to the pollution of our world, affect the health of animals and humans, and requires energy to make.
Explanation:
Synthetic materials, also known as man-made or artificial materials, have made significant contributions to human society. Like Improved Performance and Durability, Expanded Range of Applications, etc.
Here are three ways in which synthetic materials benefit us:
Synthetic materials often possess superior properties compared to natural materials, such as increased strength, durability, and resistance to wear and tear.
Expanded Range of Applications: Synthetic materials have opened up new possibilities by offering characteristics that may not be readily available in nature.
Resource Conservation and Environmental Benefits: Synthetic materials can help conserve natural resources by providing alternatives to scarce or unsustainable materials.
Thus, while synthetic materials have numerous benefits, it is essential to consider their environmental impact throughout their lifecycle, including disposal and potential hazards.

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.
