Answer:indirect causes of disease include genetics, lifestyle, and environmental factors
Explanation:
The indirect disease -causing factors include some genetic factors, infections from other persons etc. Thus options A ,C and D are correct.
What are indirect disease -causing factors?There are some factors such as infection from other people make us infected also not by directly originating in ourselves. For example, passive smokers may have respiratory disorders.
Some disease can be generated indirectly from the gene types inherited from parents. These may cause imperfect gene coding and some times trigger cancer.
Infections such as flu, cold, different types of fevers, viral and bacterial infection are able to spread and might affect other two-three people.
Therefore, indirect disease -causing factors includes genetic disorders inherited from parents and infections from environment and hence options A, C and D are correct options.

How many reactants are there?
DONE
Answer:
1
Explanation:
By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.
What is reactant?A reactant is a substance or can say a chemical compound that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.
For example we take a reaction-
O₂(g) + H₂(g) → H₂O(g)
Here, O₂ and H₂ are the reactants and H₂O is the product.
A reactant is present 100% initially and after sometimes it reduces gradually to form product according to chemical kinetics.
Given, the picture shown and the colour and texture of the reactant is shown.
Therefore, By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.

If 0.20 bushel is 1 dozen apples and a dozen apples has a mass of 2.0 kg, what is the mass of 0.50 bushel of apples?
Answer:
Mass of 0.50 bushel = 5 Kg
Explanation:
Given data:
Number of apples in 0.20 bushel = 1 dozen
Mass of 1 dozen apple = 2.0 Kg
Mass of 0.50 bushel apple = ?
Solution:
First of all we will calculate the number of dozen of apple in 0.50 bushel.
(1/0.20) ×0.50 = 2.5 dozen
Mass of 0.50 bushel = 2.5 dozen × 2.0 Kg/1 dozen
Mass of 0.50 bushel = 5 Kg

Complete Question:
Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container?
Group of answer choices
A. A chemical change started immediately and finished at eight minutes.
B. A non-chemical change started immediately and finished at eight minutes.
C. A chemical change occurred at four minutes.
D. A non-chemical change occurred at four minutes.
Answer:
A. A chemical change started immediately and finished at eight minutes.
Explanation:
A chemical reaction can be defined as the chemical process which typically involves the reaction between two or more chemical elements (substances) to form a new compound, through the rearrangement of the ionic or molecular structure of each chemical element.
This ultimately implies that, a chemical reaction is a chemical change that immediately starts when two or more molecules of a chemical element (substance) known as reactants are combined together to form a new product (compound).
In this scenario, Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. Thus, what this represent about the type of change happening in the container is that, a chemical change (from red to blue) started immediately and finished at eight minutes.

Tanisha is mixing powdered orange drink mix into a cup. She wants to make sure the orange taste is strong, so she adds a lot of powdered mix. As she is mixing, she notices that the powdered mix starts to float around in the water in clumps, and some settles on the bottom of the cup. Predict why this would happen.
A.
The powder is too old to dissolve in the water.
B.
No more powder will dissolve in the water.
C.
The powder needs to be shaken to fully dissolve.
D.
The powder does not fully dissolve because the water is too warm.
Answer:
B. No more powder will dissolve in the water.
Explanation:
If a lot of powder is added to the water, then a fully saturated solution would be created. This means that no matter how much more powder is added or how strong the mix is shaken, no more powder will disolve. The powder will instead remain in solid form in the solution.
Answer:
Heat up the water first because it increases solubility of the powdered mix.

why is the symbol Ar used in the electron configuration of potassium, and what does it represent?
Answer:
It represents the noble gas that precedes the period before Potassium.
Explanation:
Period before potassium is 3, the noble gas in that period is Ar (Argon). So when condensing the electron configuration of Potassium, Argon can account for 18 electrons instead of writing out 18 electrons in full form from 1s2, 2s2 etc.

Measured in grams of solute per gram of solution
concentration
solubility
Answer:
Solubility
Explanation:
Solubility units that incorporate units of solution include grams of solute per 100 grams of solution or grams of solute per liter of solution. Another way to express solubility is in moles of solute per liter of solution; this ratio is called "molarity."
A student heats a 2.5 g sample of calcium carbonate in a test tube. What mass of calcium oxide remains in the test tube when the reaction is complete?
CaCO3(s) = CaO(s) + CO2(g)
Select one:
a. 1.4 g CaO
b. 2.1 g CaO
c. 2.5 g CaO
d. 1.0 g CaO
Answer:
1.4 g CaO
Explanation:
Given data:
Mass of calcium carbonate = 2.5 g
Mass of Cao remain in tube = ?
Solution:
Chemical equation:
CaCO₃ → CaO + CO₂
Number of moles of CaO:
Number of moles = mass/molar mass
Number of moles = 2.5 g/ 100 g/mol
Number of moles = 0.025 mol
now we will compare the moles of CaO with CaCO₃.
CaCO₃ : CaO
1 : 1
0.025 : 0.025
Mass of CaO:
Mass = number of moles × molar mass
Mass = 0.025 mol × 56 g/mol
Mass = 1.4 g
Answer:
1.4g CaO
Explanation:
Did the exam and got it right. Hope this helps
