An insecticide kills many insects, but a few survive. Because of natural selection, which of the following is most likely to happen
1- Eventually the survivors will become resistant to insecticide
2- the survivors will reproduce, and the offspring will be resistant to the insecticide
3- the survivors will reproduce, but the offspring will be killed by another application of the insecticide
4- the survivors will continue to survive for many years beyond their normal lifespan
Answer:
2
Explanation:
the ones that survived are the ones that had the favorable trait, so they'll be able to reproduce and their offsprings are likely to receive that trait as well.

A chemist working for Udensi industries wants to create a new ink for tattoos and cosmetics. Determine the theoretical yield of iron (ll) sulfide if the chemist uses 22.5 grams of iron ? Type of rxn : AD , SR, DR , D Type of calculation : mol to mol ; mol to mass ; mass to mols mass to mass Fe S8--> Fes
Answer:
35.36 g
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
8Fe + S₈ —> 8FeS
Next, we shall determine the mass of Fe that reacted and the mass of FeS produced from the balanced equation. This can be obtained as follow:
Molar mass of Fe = 56 g/mol
Mass of Fe from the balanced equation = 8 × 56 = 448 g
Molar mass of FeS = 56 + 32 = 88 g/mol
Mass of FeS from the balanced equation = 8 × 88 = 704 g
SUMMARY:
From the balanced equation above,
448 g of Fe reacted to produce 704 g of FeS.
Finally, we shall determine the theoretical yield of FeS as follow:
From the balanced equation above,
448 g of Fe reacted to produce 704 g of FeS.
Therefore, 22.5 g of Fe will react to produce = (22.5 × 704)/448 = 35.36 g of FeS.
Thus, the theoretical yield of FeS is 35.36 g

Answer:
I believe that it is the 2nd option.
Explanation:
My reasonings are because C4H10O has 7 isomers. In which 4 are alcohol and the other 3 are ether.
The first option is ethers, specifically ethoxyethane.
The third option is ethers, specifically 1-methoxypropane.
The fourth option is an alcohol, specifically 1- butanol.
Therefore, leads us to the 2nd option that it is NOT an isomer of C4H10O

PLEASE HELP What's the mass in grams of 0.442 moles of calcium bromide, CaBr2? The atomic
weight of Ca is 40.1 and the atomic weight of Br is 79.9.
A) 452.3 g
B) 53.04 g
C) 44.2 g
D) 88.4 g
Answer: Thus there are 88.4 g of calcium bromide.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
Molar mass of = 40.1 (1)+ 2(79.9) = 199.9
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
[tex]0.442=\frac{x}{199.9}[/tex]
[tex]x=88.4g[/tex]
Thus there are 88.4 g of calcium bromide.

A. An element is made of more than one
type of atom.
B. A molecule has properties different
from the elements making up the
molecule.
C. An element shares electrons and a
molecule does not.
Answer:
A
Explanation:
Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.

"What is the potential energy relative to the water surface of a diver at the top of a 26 m
high diving platform? Suppose she has a mass of 35 kilograms."
Answer:
PE = 8918 J
Explanation:
Formula for potential energy here is;
PE = mgh
Where;
m is mass
g is acceleration due to gravity
h is height
We are given;
m = 35 kg
h = 26 m
Thus;
PE = 35 × 9.8 × 26
PE = 8918 J

Dogs are derived from wolves. Today, dogs are very diverse, varying in size from very small to very large. What led to this variety
1 - selective breeding
2- cloning
3- Genetic Engineering
4- Natural Selection
Answer:
1
Explanation:
i think but yes
Dogs are derived from wolves. Dogs are very diverse, varying in size from very small to very large. The variety is because of selective breeding. Hence option 1 is correct.
What is selective breeding?Selective breeding is defined as the method by which people pick which male and female animals or plants would reproduce sexually and create offspring together in order to selectively acquire specific phenotypic features. The goal of selective breeding is to produce cattle with desirable features that are strongly heritable and can thus be passed down from generation to generation.
Despite the fact that all dogs are descended from wolves, people have significantly changed the appearance of dogs through the use of artificial selection. Dogs have been bred for various desirable traits for ages, resulting in a vast variety of canines, from the little Chihuahua to the enormous Great Dane.
Thus, dogs are derived from wolves. Dogs are very diverse, varying in size from very small to very large. The variety is because of selective breeding. Hence option 1 is correct.

Use different words
Have a great day!
pls give brainliest and hit the heart if this helped :3
Explanation:
The changes I observed are that when you do not use hot water, the food coloring stays at the bottom and doesn't spread to the top, but when I do use food coloring, it spreads everywhere in the water. I don't know what caused the changes I observed, but I think its because heating food coloring does something to it to make it spread, maybe hotter liquids spread faster?
A motor boat is traveling 10 m/s on a sunny calm day. The driver turns
off the engine. Apply Newton's first law to explain what happens to the
boat as it glides through the water. *
Answer:
If there is no resistance, current, wind, or friction on the boat, the boat would keep moving in the same direction at the same speed.
Explanation:
Newton's First Law of Motion suggests that if no external force acts upon an object, that object would continue moving in the same direction at the initial speed.
However, all objects near the surface of the earth (including the boat in this question) experience the effect of gravitational pull (an external force from the earth.) Because of these external forces, Newton's First Law of motion (when phrased in this way) would not apply to the boat.
It is frequently possible to use a more general version of this statement: if the net force on an object is zero, that object would continue moving in the same direction at the initial speed.
In other words, the object would move in the same direction at the initial speed as long as all the external forces on that object balance each other.
Assume that there is no resistance, current, wind, or friction on the boat. After the engine of the boat is turned off, the following would be the forces on this boat:
downward gravitational attraction from the earth, andupward buoyancy from the water, which counteracts the gravitational attraction on the boat.If the water is sufficiently calm, these two forces would balance one another. The external force on this boat would be zero. Hence, the boat would keep moving in the same direction at the same speed.

how many grams of carbon tetrachloride can be produced from reacting 709.0 grams of chlorine (CI2) with excess methane?
A sample of gas has a volume of 12.0L and a pressure of 2.00 atm. If the pressure of gas is increased to 6.00 atm, what is the new volume of the gas?
A. 2L
B. 4L
C. 16 L
D. 8L
Answer:
B; 4 L
Explanation:
From the Boyle’s law of gases, the volume occupied by a given mass of gas is inversely proportional to the pressure exerted by the gas
Mathematically, we have this as;
PV = K
Given;
P1 = 2 atm
V1 = 12 l
P2 = 6 atm
V2 = ?
We have that;
P1V1 = P2V2
2 * 12 = 6 * V2
V2 = (2 * 12)/6
V2 = 24/6
V2 = 4 L

Explanation:
What is the concentration of chlorine in ppm, in a 2.0L sample of pool water that contains 5.2mg of chlorine. How do I do this problem
Answer: 2.6 ppm
Explanation: ppm is parts per million, also 1:1000 000.
It means 1 mg in 1000 000 mg is same as 1 mg in 1000 g
Assume 2.0 litres weighs 2.0 kg = 2000 g
In one litre there is 2.6 mg Cl. You get a proportion 2.6 mg :1000 g
The concentration of chlorine is 2.6 ppm.
What is concentration?Concentration can be calculated in terms of Parts per million, or ppm, that is a measurement of dissolved solids in solution expressed as a ratio of the count of parts of solids/solute to one million parts of total volume.
The concentration can be calculated by using the formula:
C = m / v
where, C is concentration, m is mass and v is volume.
Calculation of concentration is shown as:
By using the formula, C = m / v
Put the values of m = 5.2 mg and v = 2 L in concentration formula.
C = 5.2 mg / 2 L
C = 2.6 ppm
Therefore, the concentration of solution will be 2.6 ppm.
