Assume that S. typhi immediately enters the bloodstream from the small intestine. Of the following, which would be the first major organ that bloodborne S. typhi would encounter?
A. Stomach.
B. Pancreas.
C. Large intestine.
D. Liver.
Answers
Answer:
D. Liver.
Explanation:
Blood from the small intestine is taken to the liver. For this reason, we can state that if S. typhi enters the bloodstream through the small intestine, the first organ it would affect would be the liver.
The liver receives blood from the small intestine to be able to remove all toxins or useless substances from this blood and regulate how the distribution of nutrients contained in the blood will be to other parts of the body.
In an experimental test of the effects of vitamin B12 on problem-solving performance, _____ is the independent variable and _____ is the dependent variable.
Answers
Answer:
Vitamin C is the independent variable and problem solving performance is the dependent variable.
Explanation:
The independent variable is the variable that can be manipulated or changed to measure its effect. Vitamin C dosage can be changed for difference individuals to see the effect on their problem solving performance.
Dependent variable is the variable on which the effect of independent variable is measure i.e the effect of vitamins C with different dosage will be known or measured base on problem solving performance of an individual.
Therefore ability to solve problems by individual after the intake of vitamin C means its depends on Vitamin C intake.

Why is the action of phagocytes considered a nonspecific response?
It does not occur at any specific temperature.
It is not involved with the production of any specific type of lymphocyte.
It does not respond to any specific type of hormone.
It is not a response to a specific type of pathogen.
I haven't seen any answers here that are correct so I'm sharing this information :)
Answers
Answer:
The answer is "Option D".
Explanation:
The action of phagocytes is deemed a quasi answer because it reacts with any particularity on any harmful substance. It is a mechanism where a cell uses its cell membranes to collect any molecules. Macrophages provide the first layer of defense of our system, a non-specific defense mechanism. Your immune response must handle multiple forms of foreign particles, germs, viruses, or harmful proteins. This failure to respond renders the overall response quicker than that of the specific response.
Answer:
It is D. It is not a response to a specific type of pathogen.

Immune responses can be either innate (nonspecific) or adaptive (specific). Suppose a person comes into contact with bacteria that cause a disease that the person has experienced previously. The production of antibodies to fight off the infection is considered an _____ response, while the development of a fever to inhibit bacterial growth is considered an _____ response. (the possible answers to the blanks are "Adaptive" and "Innate")
Answers
Answer:
adaptive; innate
Explanation:
The adaptive immune system refers to a specific type of immunity which is found only in vertebrates. Adaptive immunity is defined by the presence of specialized immune cells (i.e., lymphocytes such as T and B cells). The B cells produce molecules known as antibodies which destroy specific pathogenic microorganisms (e.g., bacteria, viruses) and thus prevent diseases in the future. On the other hand, the innate immune system is the first (and evolutionary more ancient) defense line against pathogenic infections or tissue injury. Innate immunity includes, among others, physical barriers, anatomical barriers, phagocytic enzymes (i.e., lysozymes), phagocytic cells (i.e., macrophages), inflammation, etc. Inflammation is defined as an innate immune response composed of complex biological processes that protect the body by eliminating harmful microorganisms and intracellular danger signals, thereby regulating signaling pathways of many diseases.

1. Suppose you want to design and build a house. How would you communicate your design plans with the construction crew that would work on the house?
2. Cells build large, complicated molecules, such as proteins. What do you think cells use as their "design plans" for proteins?
Answers
Answer:
The correct answer is -
1. blueprints.
2. cells use DNA as their design plans
Explanation:
Blueprint is a representative drawing of an engineering plan that helps in understanding how and where the desired to construct on the house. It helps in communicating what work should be done in the house. It helps in visualizing how the end product should be.
In cells, the design plan is DNA that encodes all the information in a specific nitrogenous base sequence in order to produce specific functions and produce all the proteins
