Why is the bombardier beetle relevant in the evolution vs. creationism discussion? what do you think the bombardier beetle shows us in this debate?
Answers
Bombardier beetle is relevant in evolution vs. creationism as creationists use bombardier beetle to challenge evolution whereas scientists say species may have evolved the ability to survive toads’ digestive system.
A subgroup of ground beetles known as bombardier beetles includes several hundred distinct species. To defend themselves from predators, these insects have tools.
When agitated, the beetle uses unique glands in its abdomen to spray a boiling chemical solution onto the face of its predator. Hydroquinone and hydrogen peroxide are combined to create the solution, which they then mix and let loose on their foes.
Even the bombardier beetle could suffer devastating effects from any change to these two substances.
Therefore, evolution is not supposed to occur in a sound manner because it could have disastrous effects and lead to modification instead of modification.
So, while it may be appropriate in a very small number of circumstances, evolution is not appropriate in general.

2 How many
molecules of water are
there in 1g of water CH₂)
Answers
Answer:
3.3345 x 10^22
Now you can calculate easily the number of water molecules present in 1 g of water. Calculation follows
18 g of water contains 1 mol of water molecules.
or 18 g of water contains 6.022 x 10^23 water molecules.
or 1 g of water contains (6.022 x 10^23)/ 18 water molecules and the number comes out to be 3.3455 x 10^22.
So the number of water molecules present in 1 g of water is 3.3455 x 10^22.

4) Find the mass of 1.46 mol of Al2(SO4)3.
Answers
Answer:
1.46mol of Al2(SO4)3 weights 499.5 grams
Explanation:
First we will find the gram formula mass of Al2(SO4)3.
Al * 2 = 26.98 g/mol * 2 = 53.96 g
SO4 * 3 = 96.06 g/mol * 3 = 288.18
53.96 + 288.18 = 342.14 g
That is the mass of 1 mol of AL2(SO4)3.
Now we will multiply 342.14g by 1.46.
342.14 * 1.46 = 499.5244 g
Or ... 499.5 g

Answers
Gastropods include snails and slugs. They use their foot to crawl. They live in many diverse habitats, from gardens to deserts and mountains. They also live in rivers, lakes and the ocean. Most shelled gastropods have a one-piece shell that is typically coiled or spiraled, but not all gastropods have shells. Gastropods have no sense of hearing, but they can see and have a keen sense of smell.
Bivalves include clams, scallops, oysters, and mussels. As their name implies, they have two parts of their shell, which can open and close. Bivalves live in both marine and freshwater habitats. Most bivalves have a pair of large gills that enable them to extract oxygen from the water (to breathe) and to capture food. Bivalves have a mouth, heart, intestine, gills, and stomach, but no head. Bivalves have a muscular foot, which in many species such as clams, is used to anchor their body to a surface or dig down into the sand.
Cephalopods include the octopus and squid. They have a prominent head and a well-developed brain. Typically the foot has been modified into a set of arms or tentacles. Members of this class can change color. They can also change texture and body shape, and, and if those camouflage techniques don't work, they can still "disappear" in a cloud of ink. Cephalopods have three hearts that pump blue blood, they're jet powered by their muscular foot, and they're found in all oceans of the world. Cephalopods are thought to be the most intelligent of invertebrates. They have eyes and other senses that rival those of humans.

Answers
Answer:
See explanation
Explanation:
The major difference between distance and displacement is that distance is a scalar quantity while displacement is a vector quantity. Scalar quantities have magnitude without direction while vector quantities have both magnitude and direction.
The distance covered by Benjamina in both cases just refer to the difference in her position at each time without reference to the direction in which she changed her position.
Her displacement will clearly mention the direction in which she moved both when she walked to the front door of her apartment and when she walked to a friend's apartment.

sodium chloride (nacl) dissolves well in water because it select one: a. has the same mass as water. b. has charges that allow it to interact with water. c. is a nonpolar compound. d. and water are excellent solutes.
Answers
Sodium chloride dissolves well in water because it has charges that allow it to interact with water.
Ionic compounds include sodium chloride. The ions in the solute are attracted to water because it is a polar molecule. The sodium chloride crystal dissolves when the surrounding water molecules draw the sodium and chlorine ions one at a time into the solution.
The partial negative charge on the O atom of water attracts the Na+ ions because opposite charges are drawn to one another.
The ionic link that held sodium and chloride ions together is broken when water molecules force the ions apart. As seen in this picture, the sodium and chloride atoms are encircled by water molecules after the salt compounds are separated. After that, the salt dissolves and forms a homogenous solution.

Type the correct answer in the box. a pharmacist works with a 1.75 m solution of sodium bromide (nabr) and water. the volume of the solution is 84.0 milliliters. if the pharmacist dilutes the solution to 1.00 m, what is the volume of the new solution? express your answer to three significant figures. the volume of the new solution is milliliters.
Answers
Answer: 147 mL
Explanation:
Given:
Molarity of the sodium bromide (NaBr) solution (M1) = 1.75 M
Volume of the solution (V1) = 84 mL
Molarity of the diluted NaBr solution (M2) = 1 M
Using the dilution formula to solve for V2:
\(\begin{gathered}M_{1} V_{1}=M_{2} V_{2} \\V_{2}=(1.75 \mathrm{M} \times 84 \mathrm{~mL}) / 1 \mathrm{M} \\V_{2}=147 \mathrm{~mL}\end{gathered}\)

What is Decomposition Reaction
Answers
Answer:
Explanation:
Decomposition reaction, also known as analysis or dissociation, is a type of chemical reaction in which a compound breaks down into simpler substances or elements. In this reaction, a single reactant undergoes a chemical change and produces two or more products.
The decomposition reaction can be represented by the general equation:
AB → A + B
Where AB is the reactant, and A and B are the products. The reactant AB is usually a compound, and it breaks down into its constituent elements or simpler compounds.
There are different types of decomposition reactions, including:
Thermal decomposition: It occurs when a compound is heated, resulting in its decomposition into simpler substances. For example, the thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2):
CaCO3 → CaO + CO2
Electrolytic decomposition: It takes place when an electric current is passed through an electrolyte, causing it to break down into its component ions. For instance, the electrolysis of water (H2O) leads to the decomposition into hydrogen gas (H2) and oxygen gas (O2):
2H2O → 2H2 + O2
Photochemical decomposition: It occurs when a compound undergoes decomposition due to exposure to light energy. Chlorine gas (Cl2) can decompose into chlorine atoms (Cl) under the influence of light:
Cl2 → 2Cl
These are just a few examples of decomposition reactions. They are important in various chemical processes and are used in industries, laboratory experiments, and natural phenomena. By understanding and controlling decomposition reactions, scientists can gain insights into the behavior of different compounds and develop practical applications in fields such as chemistry, materials science, and environmental science.

What is the correct formula when Ca+2 is combined with PO4-3
Answers
When Ca+2 is combined with PO4-3, the correct formula is Ca3(PO4)2 to achieve electrical neutrality.
Calcium (Ca) is a metal with a charge of +2, indicated by the +2 superscript. Phosphate (PO4) is a polyatomic ion with a charge of -3, indicated by the -3 superscript. In order to form a neutral compound, the charges of the ions must balance each other.
To achieve electrical neutrality, three Ca+2 ions are needed to balance the charge of two PO4-3 ions. Each Ca+2 ion has a charge of +2, so three Ca+2 ions contribute a total charge of +6. Similarly, each PO4-3 ion has a charge of -3, so two PO4-3 ions contribute a total charge of -6. Therefore, the compound Ca3(PO4)2 ensures that the charges are balanced, resulting in a neutral compound.
In the formula, the subscripts indicate the number of atoms present in the compound. There are three calcium ions (Ca) and two phosphate ions (PO4) present in the compound. The formula Ca3(PO4)2 represents the combination of calcium and phosphate ions in the correct ratio to maintain electrical neutrality.
