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.

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.

Transmission electron microscopes that use high-energy electrons accelerated over a range from 40.0 to 100 kV are employed in many applications including the study of biological samples (like a virus) and nanoscience research and development (alloy particles and carbon nanotubes, for example). What would be the spatial limitation (in pm) for this range of electrons

Answers

Answer:

Explanation:

Using the concept of de Broglie wavelength under relativistic conditions to determine the spatial limits for electron range.

de Broglie wave-length [tex]\lambda = \dfrac{h}{p}[/tex]

where;

h = plank's constant

p = momentum of particle which is expressed as:

[tex]p = \dfrac{\sqrt{k^2+2kmc^2}}{c}[/tex]

replacing the expression for (p) into [tex]\lambda = \dfrac{h}{p}[/tex], we have:

[tex]\lambda = \dfrac{h}{\dfrac{\sqrt{k^2 +2kmc^2}}{c}}[/tex]

[tex]\lambda = \dfrac{hc}{\sqrt{k^2+2kmc^2}} --- (1)[/tex]

here;

c = velocity of light = 3 × 10⁸ m/s

h = 4.13 × 10⁻¹⁵ eV.s

i.e.

hc = (4.13 × 10⁻¹⁵ eV.s)(3 × 10⁸ m/s)

hc = 1240 eV.m

The electron's rest energy (mc²) = 0.511 × 10⁶ eV

For the elctrons;

the minimum accelerated voltage = 40kV

the maximum accelerated voltage = 100 kV

the minimum K.E of the electron K = eΔV

K = e × 40 kV

K = 40 KeV

K = 40 × 10³ eV

From equation (1);

[tex]\lambda = \dfrac{hc}{\sqrt{k^2 +2kmc^2}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(40 \times 10^3 \ eV)^2 +2(40 \times 10^3 \ eV)(0.511 \times 10^6 \ eV})}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{((1600000000) +(80000\times 511000))eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{((1600000000) +(40880000000)eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(42480000000) \ eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{206106.769 \ eV}}[/tex]

[tex]\lambda = 0.062 \ nm[/tex]

[tex]\mathbf{\lambda = 6.20 \ pm}[/tex]

The maximum K.E of the electron K = eΔV

K = e × 10 kV

K = 10 KeV

K = 100 × 10³ eV

From equation (1);

[tex]\lambda = \dfrac{hc}{\sqrt{k^2 +2kmc^2}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(100 \times 10^3 \ eV)^2 +2(100 \times 10^3 \ eV)(0.511 \times 10^6 \ eV})}[/tex]

[tex]\lambda = 0.037 \ nm[/tex]

[tex]\mathbf{\lambda = 3.70 \ pm}[/tex]

As a result, the spatial limits for the electron's range span from 6.02 pm to 3.70 pm.

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

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.

It is D. It is not a response to a specific type of pathogen.

An ecosystem is defined as a self supportiung unit that is made up of a living part (biotic factors) like plants and animals; and non-living part (abiotic factors) like water, soil, air.

In an ecosystem, the biotic community includes population of:

Food producers: That is the autotrophs like the green plants which are seen in the attached diagram.

Food consumers : That is the heterotrophs such as animals and human beings.

The non-living part of an ecosystem is its abiotic component. this consist of:

Abiotic resources: These are what organisms need to stay alive. they include a source of energy (sunlight as seen in the diagram) and inorganic nutrients ( carbon dioxide, water).
