The study of the properties of matter and how matter changes is called

Answers

Chemistry is the study of properties of matter and how matter changes .

Final answer:

Chemistry is the study of the properties of matter and how matter changes. This study includes the concepts of chemical changes, which refers to the transformation of one kind of matter into another, and chemical properties, which describe the behavior of matter in relation to changes it undergoes when it transforms.

Explanation:

The study of the properties of matter and how matter changes is referred to as Chemistry. Chemistry is a physical science that deals with the structure, composition, properties, and reactions of matter. Furthermore, it also encompasses the concepts of chemical changes and chemical properties. A chemical change refers to a process that changes one kind of matter into another kind, producing a different kind of matter from the original. Chemical properties, on the other hand, describe the behavior of matter related to changes it undergoes when it transforms to another kind of matter.

For instance, if you heat sugar, it undergoes a chemical change and transforms into caramel. The change in taste, color, and other properties from sugar to caramel is part of the chemical properties involved in the chemical change.

Body defenses that respond to generalized tissue damage and many common pathogens are referred to as

Answers

Body defenses that respond to generalized tissue damage and many common pathogens are referred to as nonspecific mechanisms. It refers to the innate immune system. It is an essential system of the overall immune system of the body as it consists of cells and mechanisms that would defend the body from infection. Example would be the skin. It is the very first line of defense of the body against any foreign materials. It acts an almost impenetrable barrier to pathogens keeping them outside. The skin has oils and sweat making it acidic so it inhibits the growth of a number of microorganisms.

The student's question relates to the nonspecific innate immune response, which is the body's first line of defense, acting rapidly against a variety of pathogens through barrier mechanisms like skin and mucous membranes, and other innate defense cells.

The student is asking about a type of immune response known as the nonspecific innate immune response. This response acts as a first line of defense against potential pathogens and is characterized by a generalized reaction to a variety of pathogens, rather than a targeted attack on a specific one. The nonspecific innate defenses include barrier mechanisms such as the skin and mucous membranes, which provide immediate protection.

These defenses are constantly active, preventing a broad range of pathogens from entering the body. Additionally, the innate immune system includes a variety of specialized cells and soluble factors that engage in a rapid response to invaders. Importantly, these defenses are called innate because they are built-in components of our physiology and do not have the ability to 'remember' or improve response upon repeated exposures to the same pathogen, as opposed to the adaptive immune system, which has this capability.

A patient undergoing chemotherapy for lymphoma (cancer) was advised to get rid of the house plants in her home. what is the possible reasoning behind this suggestion?

Answers

Chemotherapy patients are advised against gardening, planting or any form of contact with soil. The soil in the pots is a huge source of bacteria and mold, which presents an unnecessary danger to the patient. Removing indoor houseplants and flowers are also advised because these items tend to shed mold in the air and can be a source of infection. It is also important to not keep cut flowers inside the house because the water in the vases can harbor infectious bacteria and can evaporate in the air and spread to the patient.

Final answer:

Mesenchymal cells are most commonly found in embryonic connective tissue. They are multipotent stem cells that can differentiate into any type of connective tissue cells. These cells play a vital role in the formation of diverse body tissues, such as bones, cartilage, and fibrous connective tissues.

Explanation:

Mesenchymal cells, a type of multipotent adult stem cell, are most commonly found in embryonic connective tissue. These cells can differentiate into any kind of connective tissue cells required to restore and heal damaged tissue. They originate from the mesenchymal stem cell line, the first connective tissue to develop in the embryo. Clusters of these cells are scattered throughout adult tissues.

Moreover, mesenchymal cells contribute to the formation of diverse types of connective tissues. They originate withinside the mesodermal germ layer and differentiate from mesenchyme and hematopoietic tissue in the bone marrow.

Drug-resistant populations of microbes arise when

Answers

There is variation within the population, due to a mutation. The selection pressure is the drug. The microbes that have the advantageous gene which makes them resistant to the drug are selected for, and reproduce passing on the gene, increasing its allele frequency within the population over time. However, the microbes that do not have the advantageous gene, cannot survive and their number decreases within the popullation.

Final answer:

Drug-resistant microbes arise from the survival and reproduction of microbes that have developed resistance to antibiotics, often due to an incomplete course of treatment. They then create new populations of resistant microbes.

Explanation:

Drug-resistant populations of microbes arise when those microbes are exposed to antibiotics but are not completely killed off. This can happen when a course of antibiotics is not fully completed, allowing some bacteria to survive and develop resistance. When those resistant bacteria reproduce, the resulting offspring also carry the resistance, leading to a whole population of bacteria that cannot be killed by that specific drug. This is why it is essential to always complete a full course of antibiotics.

When an olfactory receptor is stimulated, what type of change must happen before it signals the brain that a change has occurred?

Answers

When an olfactory receptor is stimulated, a generator potential must be produced by the receptor before it signals the brain that a change has occurred.

In order to reach the threshold of the cell, a graded potential must be generated by the neuron of the olfactory receptor. At threshold, an action potential will be generated, referred to as the generator potential. The brain then receives this generator potential in order to decode it.
