Rocks are identified primarily by the minerals they contain and by their texture. Each type of rock has a distinctive set of minerals. A rock may be made of grains of all one mineral type, such as quartzite. Much more commonly, rocks are made of a mixture of different minerals. Texture is a description of the size, shape, and arrangement of mineral grains. Are the two samples in figure 2 the same rock type? Do they have the same minerals? The same texture?
Explanation:
The cell that provides life with chemical energy. Light energy is converted by photosynthesis into chemical energy that is stored in glucose, and this energy is then released during cellular respiration to create ATP.
<h3>What does the term "cellular respiration" mean?</h3>
While cells are aerobic respiration, oxygen may be present or not. But, because the cell seems to "respire" by consuming molecular oxygen (as an electron acceptor) and releasing carbon dioxide, the process is essentially known as "cellular respiration" (as an end product).
<h3>What happens during cellular respiration?</h3>
ATP is created during cellular respiration as a reaction product between glucose and oxygen. Water and carbon dioxide are released as by products. The three stages of aerobic cellular respiration are glycolysis, an anaerobic process, and the Krebs cycle.

Phospholipids are the substance/structure that is the building block of the cell membrane. Without phospholipids, we wouldn't even have a cell membrane and wouldn't really have any way how to shield and guard or control th epassage of substances across the cell surface. The cell membrane is at the same time partially permeable; this means it will let certain ions that can be found in the intra and extracellular fluid in and out, while others will be kept from moving so freely.
Answer: the need of evolution
Explanation: Charles Darwin saw the differences between the birds beaks in the Galapagos island. The beaks were different because of the different food that the environment provides.
