The simple answer for that will be that they are not complex organisms. Earthworms are simple organism with the small body,
So as there body is not that big thus they don't need any specialized organ system for the process of respiration. Every organism has the complex systems according to fulfill their needs, and most certainly the skin is very convenient medium for the respiration by the diffusion process.
-------------------------------------------------------------------------------------------------------------
BLOOD CIRCULATORY SYSTEM:They have a specialized system where it was needed, THE BLOOD CIRCULATION SYSTEM, There body is small but long and need blood to transfer the oxygen to each part of the body. There blood have the haemoglobin(it carries the oxygen), thus it is red just like us.
--------------------------------------------------------------------------------------------------------------
SKIN:Skin as a respiratory medium, needs to be thin, wet and cover large surface area than volume. The Skin fulfills all these Prerequisites, thus it is a perfect organ for the respiration. Even our respiratory medium which is alveoli is wet, thin and cover REALLY large surface area more than our body. If the skin dries, there will be no diffusion and worm will die due to dessication.

Franklin was performing an experiment by combining hydrochloric acid and sodium hydroxide. He measured the mass of his reactant materials to be 35g. The reaction resulted in the production of salt and water. He reported that his products weighed 32g. Which best describes the results of Franklin’s experiment? No error occurred, some of the products are always lost as heat. An error occurred, the mass of the reactants should equal the mass of the products. An error occurred, the products should weigh more than the reactants. No error occurred, water is not weighed when determining the weight of the products.
Answer:
B) an error occurred, the mass of the reactants should equal the mass of the products.
Explanation:
The answer choices are:
A) no error occurred, some of the products are always lost as heat.
B) an error occurred, the mass of the reactants should equal the mass of the products.
C) an error occurred, the products should weigh more than the reactants.
D) no error occurred, water is not weighed when determining the weight of the products.
Solution
The basis to answer this question is the law of conservation of mass.
Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, the mass of the reactants equal the mass of the products.
Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: the mass of the reactants should equal the mass of the products.

What has the most control over water being a gas, liquid or solid ice? A. The amount of water B. It’s temperature C. If its being used D. It’s age
Answer:
B. Its temperature
Explanation:
The different states of matter are largely influenced by both temperature and pressure. The temperature has most control over water being a gas, liquid or solid ice. If the temperature is very high, the molecules in the water increases their kinetic energy. This movement causes the compound ([tex]H_{2} O[/tex]) to break its bond. Thus, it turns into a gas. On the contrary, if the temperature is very low, the molecules of the water moves closer to each other. This causes them to solidify and turn into ice.

Matter and Chemical Formula
Let us learn about
Atoms and molecules
Element, compound and mixture
Chemical symbol and chemical formula
Atomicity and valency
Answer:
Atoms are the basic units comprising matter, and interact in a variety of ways.
Explanation
The most fundamental unit of matter that makes up elements is called atoms. Atoms comprise nucleus-orbiting electrons- while protons and nuetrons make up a stable nuclues. Here, the neutrons are uncharged, while the negatively charged electrons are attracted to the positively charged protons at the atom's center
The number of protons the atom determines its atomic number, and the sum of protons and neutrons determine the atomic mass.
Elements in the periodic table, are typically represented by chemical symbols- abbreviations of their atomic name. They are arranged in order of valency- atoms in the same group typically have the same number f electrons on their valence shells, and thus their physical properties behave similarly (conductivity, melting points, boiling points).
Valence electrons, on outer valence shells, also influence bonding. The atoms donate, accept or share valence electrons in order to achieve more stable atoms. Bonding between elements form molecules, that may interact with molecules to form compounds.

Explain the process of radioactive decay. What happens during radioactive decay, and what is the result at the end of radioactive decay?
Answer:
this is the answer straight off the site DO NOT COPY AND PASTE but along these lines is what its looking for
Explanation:
Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.

Which statement best describes how the Great Rift Valley in Africa formed?
The rift valley formed when the crust pulled apart.
The rift valley formed due to subduction.
The rift valley formed similarly to an island arc.
The rift valley formed at a convergent boundary.
Answer:
The rift valley formed when the crust pulled apart.
Explanation:
The Great Rift Valley in Africa formed when the crust pulled apart along a divergent margin.
Rift valley systems are produced within a continent at divergent margins within a plate. The rifting system makes the earth in that region prone to frequent earthquakes as the continents continues pulling apart. It results from the divergence of the Arabian plate and the Somalia/Nubian plate. It is one of the longest rift valley systems on earth.Answer: a. The rift valley formed when the crust pulled apart

Describe nondisjunction and the effect it can have on a human.
Answer: Nondisjunction is the failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during mitosis or meiosis. During mitosis, this can cause cancer. During meiosis, this can cause Down syndrome, Turner's syndrome, and Klinefelter's syndrome.
Scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries. This bioengineered tissue is grown from living cells. The cellular process that enables the cells to grow and develop into tissue is —
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.
To keep it simple the answer is Mitosis.
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. The process is Mitosis.
What is Mitosis?A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
Mitosis can be compared to copying an instruction manual. Give two copies of each page, one to each of the two recipients.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells.
Therefore, The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. The process is Mitosis.

During cellular respiration, the electron transport chain is coupled to the generation of an electrochemical gradient across the mitochondrial inner membrane.
The statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.In cellular respiration, an electrochemical gradient is created by pumping ions (e.g. H+) against a concentration gradient from the mitochondrial matrix into the intermembrane space.Subsequently, this gradient is used by a protein complex known as ATP synthase to generate ATP (the energy coin of the cell) from ADP and monophosphate.In conclusion, the statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.
