Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated.
Answer:
The two species concepts that are most likely to place dogs and wolves together into a single species are <u><em>biological and phylogenetic</em></u> concepts.
Explanation:
- The biological species concept establishes that a species is a group in a population whose individuals can mate and have viable, fertile descendence. These groups are also reproductively isolated from other groups or species. This is, the members of a species can not reproduce with the members of other species, or they can their progeny is unviable.
- The phylogenetic species concept refers to a species as the monophyletic group that is less inclusive for organisms. It is a group of organisms that share an ancestor in common and can distinguish from other similar groups. In this concept, a unique species can include a wide phenotypic variability.
Solution:
The difference between them are:
The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,
The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.
This is the required answer.
Answer:
Temperature of the fridge
Explanation:
The independent variable is the temperature of the fridge.
The hypothesis statement would be "if coffee beans are soaked overnight in a fridge then cold coffee is produce because of the temperature of the fridge".
An independent variable is the cause in an experimental design or set up. It is the variation on this variable that produces the effect we desire to study.
The dependent variable is the cold coffee. It is the cause of putting the coffee in the fridge of overnight.
Answer: adult tissues
Explanation: Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.
