Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green
Answer:
This strange green slime is a colonization of fungi caused by the humidity of the bathrooms, which to be eradicated requires a non-specific antimicrobial such as sodium hypochlorite that generates an osmotic imbalance producing a fungicidal effect.
Explanation:
The fungi that appear in the form of slime at the microscopic level have many forms of colonization, by adding coconut milk it was assumed that this would generate an environment not suitable for their metabolism and reproduction but this did not happen, therefore they continued their reproduction.

Explanation:
Not all protists use flagella or cilia to move. Give an example of another way protists move and identify the type of protist that uses that mode of movement.
Answer: One of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia. Those same organelles may be used in feeding as well.

choose the letter that best describes the behavior of a substance during a phase change:
/A/ neither absorbs or releases energy
/B/ always absorbs energy
/C/ always releases energy
/D/ either absorbs or releases energy
Answer:
/D/ either absorbs or releases energy
Explanation:
During a phase change energy is either absorbed or released.
A phase change is a reversible process which occurs when a substance changes is its state from one form to another.
Phase changes are used to delineate physical changes.
A phase diagram provides a graphic representation of the change. The diagram can be 2 dimensional or 3 dimensional.What is the decomposition of 2LiCIO3

Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. Over time, other species are found in the disturbed areas, and the number of pioneer species decreases. Why does the number of pioneer species get less?
Answer:
The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.
Explanation:
Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. However, with time the number of pioneer species decreases.
The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.

Pedro is baking a cake for his experiment on chemical changes. He knows a chemical change will occur when he puts the cake mixture in the oven. He would like to know what will happen when the cake is removed from the oven. What prediction would you make for Pedro's experiment? A. The chemical changes occurred because the chemicals changed. B. The chemical changes occurred because there was a change in light energy. C. The fruit and the hamburgers were affected by an increase in heat energy. D.The fruit and the hamburgers were affected by a decrease in heat energy.
Answer:
A. The chemical changes occurred because the chemicals changed.
Explanation:
When baking a cake several chemical reactions occur that change the chemical composition of the ingredients used in baking. An ingredient like baking powder releases carbon dioxide when it undergoes a temperature change in the oven. A chemical change is supposed to change the form of a substance.
An endothermic reaction also occurs when the ingredients absorb heat energy to produce several changes. The firmness of the cake occurs because of the heat absorbed by the proteinous content of the egg.

Which of the following elements is the most electronegative: arsenic, phosphorus,
sulfur, or selenium?
selenium
arsenic
phosphorus
sulfur
Answer:
sulfur
Explanation:
From the given lists of elements, the one with the most electronegativity is Sulfur.
Electronegativity is of an element is a property that combines the ability of its atom to lose and gain electrons.
It is a measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.
Using the Pauling's electronegative table of elements;
Here are electronegativity values of the given elements;
selenium 2.4
arsenic 2.0
phosphorus 2.1
sulfur 2.5
We see that the value of sulfur is the highest.

How many atoms are in the following formula?
3Al2O3
Answer:
15 atoms total
Explanation:
2 Al atoms + 3 O atoms = 5 Al2O3 atoms
5 Al2O3 atoms * 3 = 15
another way to do it is:
2 Al atoms * 3 = 6 Al atoms
3 O atoms * 3 = 9 O atoms
6+9 =15 atoms total
The number of atoms in the given 3Al₂O₃ is 15 atoms.
What are atoms?Atoms are the smallest unit of every matter. It contains charged particles present inside the atoms. They are electrons, protons, and neutrons. Atoms are of four types, description, isotopes, radioactive, and ions.
These atoms are the ions, that are charged, and the charged ions make bonds with each other to form compounds. Aluminum oxide is a compound that is formed by combining aluminum and oxygen atoms.
The compound is 3Al₂O₃
This means there are three moles of aluminum, and three moles of oxygen.
2 Al atoms + 3 O atoms = 5 Al₂O₃ atoms
5 Al₂O₃ atoms x 3 = 15
The elaborative way is:
2 Al atoms x 3 = 6 Al atoms
3 O atoms x 3 = 9 O atoms
6 + 9 =15 atoms total
Thus, the number of atoms is 15 atoms.

What suprising result is explained using this model
Answer:
B. A few positive particles bounced back because they were pushed away from the positive center.
Explanation:
The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.
This is the central theme of Rutherford's experiment on a thin gold foil.
In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.Do you guys have viruses wit this website

Which describes the elements in a given group of the periodic table?
They decrease in atomic mass as you go down the column.
They increase sequentially in atomic number from top to bottom.
They are in the same family, with similar characteristics.
Their properties change according to a pattern as you go down the column.
Answer:
They are in the same family, with similar characteristics.
Explanation:
The elements in a given group of the periodic table are in the same family and with similar characteristics.
Vertical columns on the periodic table are referred to as a group or family. Elements having the same number of electrons in the outermost shell of their atoms are placed one another in vertical columns. Each resulting vertical column is a group or family. Elements in the same group exhibit similar chemical properties because of the same number of electrons in their atoms' valence shells.the number of moles in 4.5 x 10^24 atoms of oxegen is
