Answer:
The primary function of the lymphatic system is defending the body against both external and internal threats.
Explanation:
The set of tissues and organs that participate in the immune response is known as the lymphatic system. Its main functions are to maintain the volume of blood and participate in the defense of the organism. It is made up of organs, vessels, nodes and lymphatic tissue. This system fulfills three basic functions: Defense: in the lymph nodes, the lymphocytes reproduce to respond to antigens; fat absorption: most of the fats are absorbed by the lymphatic system and subsequently transported to the blood and capillary exchange: it recovers substances that the blood flow has lost in the capillary exchange.
The principal function of the lymphatic system is to remove strange or damaging substances from tissues and eliminate them. The correct option is defending the body against both external and internal threats.
------------------------------
Among other functions of the lymphatic system, its principal one is the removal of damaged cells, cancer cells, and protection of the body against the virus, bacteria, and fungi that might affect it.
The lymphatic system remove these elements from the tissues for their elimination.
All these strange microorganisms and waste substances get filtrated in the lymphatic ganglia.
Ganglia are small organs located all along with the net of lymphatic vessels, that function as lymph accumulation centers.
Lymph passes through these organs and gets filtrated and purified of waste substances.
Inside each ganglion, the lymphocytes T and lymphocytes B help the organism to fight these infections.
B cells produce antibodies that impede infection propagation by trapping the microorganisms and destroying them.
Most lymphatic ganglia are grouped near the neck, underarm, and groin.
They are also grouped in the chest, abdomen, and pelvis, where they filter blood.

What is a cell?All living organisms and body tissues are made up of cells, which are the smallest unit that can live on its own.
A cell is made up of three major components: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and regulates the substances that enter and exit the cell.
Plant and animal cells are structurally very comparable because they are both eukaryotic cells.
The nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes are all membrane-bound organelles in both.
Plant cells lack centrosomes and lysosomes, whereas animal cells do. Plant cells always possesses a cell wall, chloroplasts as well as other specialized plastids, and a large central vacuole, whereas animal cells do not.

Which axiom is used to prove that the product of two rational numbers is rational?(1 point) Integers are closed under multiplication. Integers are closed under division. Whole numbers are closed under division. Natural numbers are closed under multiplication.
Answer: Integers are closed under multiplication.
Explanation:
Rational numbers are numbers of the form:
a/b
such that a and b are integers.
The axiom: " Integers are closed under multiplication. "
Says that if we have two integers, x and y, then:
x*y is also an integer.
So if we have two rational numbers,
a/b and c/d
Such that a, b, c and d are integers, and we multiply them, we have:
(a/b)*(c/d) = (a*c/b*d)
the numerator is a*c is the product of two integers, so this is an integer by the previous axiom.
the denominator is b*d, also a product of integers, so this is an integer.
then (a*d)/(b*d) is the quotient of two integers, then this is a rational number.
Answer:

A. could not confirm the usefulness of sonar
B. could destroy the hypothesis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
The study of a living being is called biology.
The correct answer is C.

Explain why fermentation stops after
a certain time in making
making bread?
Answer:
The yeast die at 140° F
Explanation:
The fermentation process is caused by the living organisms called yeast feeding on the sugar in the dough. As the yeast feed on the sugar they release CO² which causes the bread to rise but once the bread in the oven reaches 140° all the yeast are killed off and the fermentation process stops.
The process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.
What do you mean by Fermentation?Fermentation may be defined as a process a chemical process by which molecules such as glucose are broken down anaerobically in the presence of yeast.
During fermentation, the yeast produces excess carbon dioxide due to which the dough of bread swells. But after the completion of fermentation when bread places in the oven or any other warmer temperature, it killed the yeast, and hence fermentation stops.
Therefore, the process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.

Which of the following descries a solution that contain a buffer? A. Sodium hydroxide, a base, is added to the solution, and the pH of the solution becomes higher. B. Citric acid is added to the solution, but the pH of the solution does not change. C. Acetic acid is added to the solution, and the pH of the solution becomes lower. D. Distilled water is added to the solution, and the pH of the solution does not change.
Answer:
B. Citric acid is added to the solution, but the pH of the solution does not change.
Explanation:
In chemistry, buffer solutions or simply called Buffer are solutions that resist a change in pH when an acid or base is added to them i.e they maintain a constant pH. This is as a result of the content of the solution. A buffer may contain a weak acid and its conjugate base (salt) or a weak base and its conjugate acid.
Hence, when a strong base or acid is added to them, they still restore the original pH of the solution due to the reaction that removes or neutralizes the hydrogen or hydroxide ions from the acid and base added to them respectively. This is what happens when Citric acid is added to the solution, but the pH of the solution does not change.
Citric acid, which is an acid, does not practically increase or decrease the pH of the solution. Hence, the solution is called a buffer.
Answer:
Citric acid is added to the solution, but the pH of the solution does not change.

The plateau phase of population growth is best described as: A. The population stops growing because they moved into the plateau environment at this stage. B. The population pauses in its growth after a natural disaster before growing again. C. The population moves onto a large, raised, flat area called a plateau for protection from predator. D. The population stops growing because the environment has reached its carrying capacity.
Answer:
C. The population moves onto a large, raised, flat area called a plateau for protection from predator.
Explanation:
The plateau phase of population growth indicates that the population has stopped growing as the environment has reached its carrying capacity.
What is the plateau phase in population growth?The population after going through different phases eventually reaches the plateau phase where the growth of the population stops or become constant. This is the outcome of the natality rate becoming equivalent to the mortality rate.
This occurs as the resources in the environment become less or scarce as well as there is an elevation in predators and parasites. These are considered as limiting factors to the growth of population. This makes the population number relatively stable. With the limitation in the resources it can be said that the environment has attained its carrying capacity.
Thus, the correct statement is option D.
