The toxin produced by the intestinal bacterium Vibrio cholerae induces excessive diarrhea by stimulating the excretion of NaCl and large amounts of water into the intestine. The mechanism by which cholera toxin acts is ADP ribosylation of: a. the GTP-bound form of Gai, locking it in the active conformation. b. the GDP-bound form of Gas, locking it in the inactive conformation. c. the GTP-bound form of Gas, locking it in the active conformation. d. Gaq, inhibiting its GTPase activity. e. Gai, decreasing its affinity for GDP.

Answers

Answer 1

Answer:

c. the GTP-bound form of Gas, locking it in the active conformation.

Explanation:

The reason is that the toxin created by the enteric intestinal bacterium Vibro cholerae triggers an exorbitant amount of diarrhea by inducing the excretion of NaCl and enormous amounts of water into the bowel. The mechanism by that epidemic cholera toxin acts is ADP ribosylation of the Gs alpha monetary unit. This implies that G[tex]\alpha[/tex]s macromolecule protein exploits NAD, therefore protecting it within the active conformation.

Example of form follows function in cell biology

Answers

Answer:

Example: human's arm and bat's wing share the same evolutionary origin and exhibit similar internal anatomical structures, but they have different forms because these structures have different functions

Explanation:  

The idea "Form Follows Function" indicates that the form/shape of a structure is directly associated with the function of that structure. The relation form-function is a consequence of the evolutionary process. Thus, in different species, analogous structures that share the same evolutionary origin can have different forms and/or shapes because they perform distinct functions, such as in the example above.

2. What are individual characteristics? Give an example of an individual characteristic?

Answers

Answer:

What are individual characteristics? Give an example of an individual characteristic. Individual Characteristics are properties or physical evidence that can be attached to a common source, any examples could be something such as Nuclear DNA, tool marks, and fingerprints.

What are class characteristics and how are they different from an individual characteristic? Class characteristics are not unique to a particular object but place the particular bit of evidence into a group of objects. Individual characteristics narrow down the evidence to a single, individual source. The type of handgun with which a victim is shot is a class characteristic.

What are physical and chemical properties? Give an example of each.  A physical property is an aspect of matter that can be seen or measured without changing its chemical composition. Examples of physical properties include color, molecular weight, and volume. A chemical property is observed only by changing the chemical identity of a substance. In other words, the only way to detect a chemical is to perform a chemical reaction.  Examples of chemical properties are reactivity, flammability, and oxidation state.

Individual characteristics are unique traits or attributes that distinguish one person from another.

These qualities are specific to an individual and may be influenced by genetics, environment, experiences, or personal choices.

Individual characteristics encompass a wide range of aspects, including physical features, personality traits, skills, interests, and preferences.

For instance, physical features such as eye color, height, or facial structure are individual characteristics that are genetically determined.

Personality traits like extroversion, empathy, or creativity are also individual characteristics shaped by a combination of genetic and environmental factors.

These characteristics contribute to the diversity and complexity of each person, making every individual special and different from others.

What is Heredity?

Heredity may be defined as the process by which characters are transferred from one generation to the next generation. It is also known as inheritance.

Gregor Johann Mendel is known as the father of genetics because he gives the concept of genetics and heredity by demonstrating his experiments on the garden pea plants (Pisum sativum).

He collected descriptive information on characters like seed shape, seed color, flower color, pod shape, pod color, flower position, and stem height as well as the inherited traits of such characters.

Therefore, the correct option is A.
