Can someone help me with the blanks

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.

Answer:

Carbon, Oxygen, hydrogen , Nitrogen , and phosphorus.

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.

Explanation

Answer:

Enzymes catalyze a reaction which in presence of a catalyst proceeds the reaction faster. Inorganic catalysts promote a chemical reaction between many different reactants. Enzymes are proteinaceous in nature whereas inorganic catalysts are not proteinaceous in nature.

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.

Answer:

it depends on the amount of each nutrition to make a balance meal

Answer:

false

Explanation:

There are ten major organ systems in the body, each of which plays a different role in helping the body work.

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

Answer:

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.

Answer: Ecosystem

Explanation: This image shows multiple species interacting with their environment: human and rabbit within waterfall and tree.

The level of biological organization that is illustrated by the image is called Ecosystem.

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:

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.

grp 17

Explanation:

this should be the new periodic table:) grp 1 and 2 belongs to metal. grp 18 belongs to halogen which have full valence electron thus they are inert/ unreactive. thus the ans is grp 17. grp 17 are halogens which are non metals.

Refraction

Explanation:

The bending of seismic waves is called refraction. The fact that S-waves do not travel through the outer core suggests that the latter is liquid.
