Answer:
Scientists can distinguish more than 4,000 different minerals but many are very rare. About 200 minerals make up the bulk of most rocks. The feldspar mineral family is the most abundant. Quartz, calcite, and clay minerals are also common.

Explanation:
This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.
Explanation: In mitosis, the cell splits apart to form two identical, same cells. That means that it has the same DNA and number of chromosomes as the previous cell. So, mitosis's main function is literally DNA replication
Answer: Feedback mechanism
Explanation:
Feedback mechanism is the body's way of maintaining physiologic processes in the body. These physiologic processes include maintaining homeostasis, production of energy, hormones as well as enzymes required for chemical reactions.
There are 2 types of feedback mechanism:
- Positive feedback: The stimulus (message) sent to the brain, produces prolonged increased production or increased activity in the body.
- Negative feedback: In negative feedback, the stimulus causes production, secretion or activity till a set point where the body knows it has taken enough. This causes a self termination of the process.
In the increased muscle activity, the increase in activity in turn causes a decrease in energy (ATP) and serves as the stimulus leading to the release of enzymes which in turn lead to increased absorption of glucose which will be used by the body to produce more ATP needed for the muscular activity. At the end of the muscular activity, the body recognizes that it doesn't need an increased absorption of glucose to support increased activity anymore and glucose absorption normalizes.
The percentage of energy that is unusable is obtained as 96.1 %.
<h3>What is the percentage of unusable to become new growth for the chipmunk?</h3>
We know from the law of conservation of energy that energy is neither created nor destroyed in the ecosystem but is converted from one form to another. We know that the ecosystem is a self supporting system in which there is an exchange of materials and energy. Energy flows from the producers to the consumers and some of this energy is dissipated along the way and is lost as heat during the transition.
The metabolic activities of an organism takes up some part of the energy that it receives from the sun.
From the question, we know that the energy consumed is 1000 J and the energy that is lost to waste and to respiration is 177 J and 784 J respectively. This implies that the available energy is 39J.
The percent of energy that is usable is; 39 J/100J * 100/1 = 3.9 %
The percent of energy that is unusable is; 961 J/1000 J × 100 % = 96.1 %
