Which of the following is an example of a chemical change?

A tissue contains a variety of cell types that work in conjunction to perform similar functions.

The cells are similar in structure despite being located throughout the body. There are four types of tissues in the human body: connective, epithelial, muscle, and nervous system tissues.

A ribosome is a structure of eukaryotic cells that makes proteins.

Cellulose is a complex carbohydrate that composes the better part of the cell wall.

Hemoglobin is a protein and is found in red blood cells. Adenosine triphosphate (ATP) is a compound used by living organisms to store and use energy. Estrogen is a steroid hormone that stimulates the development of female sex characteristics.

Phenotype is the physical presentation of an organism's genes. In other words, the phenotype is the physical characteristics of the organism. Phenotype is often contrasted with genotype, the genetic makeup of an organism. The genotype of the organism is not visible in its presentation, although some of the characteristics encoded in the genes have to do with physical presentation. A phylum is a group of classes that are closely related. A species is a group of like organisms that are capable of breeding together and producing similar offspring.

The best use of the International System of Units (SI) for this situation would be the use of the micrometer as it is the smallest unit of measurement provided and the scientist is using a microscope to view the insects.

The scapula, commonly known as the shoulder blade, is above the olecranon, commonly known as the elbow. Conversely, the olecranon is distal or inferior to the scapula.

In a scientific experiment, the dependent variable is the condition that is being tested and measured. The independent variable is the condition that is being changed or controlled. In this example, the amount of salt is varied, and the boiling point of water is measured. Therefore, the independent variable is the amount of salt, and the dependent variable is the temperature at which the water bolls.

Two genes next to each other (or within a specified close distance) are said to be linked. Linked genes do not follow the law of Independent assortment because they are too close together to be segregated from each other in meiosis.

Maintaining homeostasis means that conditions are kept stable and relatively constant. Negative feedback is a mechanism used to reverse or minimize changes in a system. In this example, negative feedback is used to keep the body's glucose and insulin levels stable. Positive feedback (B) is a mechanism that Increases changes in a system. A stress response (C) describes the body's reaction to threats or pressures. Parasympathetic regulation (D) refers to activities of the nervous system, including slowing the heart rate and boosting Intestinal activity.
