Answer:
1. If an organism has high biological fitness in one habitat, this does not mean it will have high fitness in another. This is because organisms adapt accordingly to their environment. Therefore, since there is variability among habitats, this does not guarantee that the organism will always have high biological fitness.
2. Natural selection produces changes in populations. Individual organisms are directly impacted by it, as it determines their survival rate, but the only genetic changes would occur in a population.
3. If there are no organisms with varying traits in a population, they will likely go extinct after a major environmental change. This is because natural selection will remove all organisms who are unable to survive in the new environment. If the population does not have the variability to survive this, then they will go extinct.
If an organism has a high biological fitness in one habitat, then it doesn't guarantee a high biological fitness in a different habitat; natural selection does change the individual. The population will go extinct if the individuals can't reproduce.
What is the individual survival chance?The individual that lives in an ecosystem can change itself due to natural selection, as natural selection favors the individuals who can survive in the changing environment, and the change in the environment induces the change in the organism. There is no reproductive success if the organisms are reproductively isolated within the population.
Hence, if an organism has a high biological fitness in one habitat, it doesn't guarantee a high biological fitness in a different habitat; natural selection does change the individual. The population will go extinct if the individuals can't reproduce.

For the balanced equation shown below, how many moles of Al will react with 98.7 moles of CuSO4
Answer:
65.8 mol
Explanation:
Step 1: Write the balanced equation for the single displacement reaction
2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + 3 Cu
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Al to CuSO₄ is 2:3.
Step 3: Calculate the number of moles of Al that will react with 98.7 moles of CuSO₄
98.7 mol CuSO₄ × 2 mol Al/3 mol CuSO₄ = 65.8 mol Al
1.I make my cup of coffee in the morning by pouring boiling water over ground-up coffee beans held in a special piece of paper and by collecting the brown liquid that comes through. Which techniques of the five described in the background section is/are used in the preparation of the cup of coffee
Answer:
Filtration
Explanation:
Filtration is a physical separation technique that is used to separate solids from liquids or gases. The process involves the use of a filter which allows just the liquid to pass through.
In this case, the coffee beans is the solid and the boiling water is the liquid. The special piece of paper is the medium (filter) through which the coffee is collected.
The coffee coming through the special piece of paper (filter) is called a filtrate.
Filtration is used in the preparation of the cup of coffee.

Explain the difference between endothermic and exothermic processes. Provide an example of each.
These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.
Examples:
Combustion
Neutralisation between acids and alkali
Endothermic reactionsThese are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.
Example:
Electrolysis

Highlight your answers by drawing appropriate chemical structures for aspirin at each of the pH values.
Answer:
don't sent such messages whatever you are
According to the concept of solubility and dissociation, aspirin at pH 8 and 10 undergoes dissociation to yield ions.
What are ions?
An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.
Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.Ions are generated on dissociation.

Jewelry and tableware are sometimes made of sterling silver. Sterling silver is 92.5% silver (Ag) and 7.5% copper (Cu). If you wanted to make 30 grams of sterling silver for a ring, how many grams of silver and copper would you need to start with?
Amount of sterling silver?
Amount of copper?
total grams of alloys needed?
Answer:
12.33
Explanation:
92.5/7.5= 12.33
30g of the sterling silver ring contains, 27.75 g of silver and 2.25 g of copper.
What is cross multiplication?Cross multiply fractions by multiplying one fraction's denominator by the other fraction's numerator and then comparing the two values. The larger fraction is the one with the higher value.
100g of sterling silver contains 92.5g of silver and 7.5g of copper.percentage of element = amount of the element present in 100 g of materialTherefore,
100g sterling silver = 92.5g silver30g sterling silver = X g silver( cross multiplication),
100 × X = 92.5 × 30
X = 92.5 × 30/ 100
X= 27.75g silver100g sterling silver = 7.5g copper
30g sterling silver= Y g copper
(cross multiply)
100 × Y = 7.5 × 30
Y= 7.5 × 30 / 100
Y= 2.25g copperX (silver)= 27.75 g in 30 g of sterling silverY (copper)= 2.25 g in 30 g of sterling silvertherefore, 30g of sterling silver ring contains, 27.75 g of silver and 2.25 g of copper.

Answer:
Mean: 350
Median: 300
Range: 650
Mode: 300
Explanation:
Mean: 800+300+150+300+200= 1750, 1750 divided by 5 = 350
You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS to find the mean.
Median: (150, 200, 300, 300, 800)
To find Median put the numbers in order from greatest to least then you choose the middle number.
Range: Range is the distance from the smallest number to the largest the way to solve this is (Highest number) - (lowest number). In your case its 800-150 which equals 650
Mode: The mode is the value that appears most frequently in a data set.

Answer:
Not exactly But you can take the slope of the curved portion and the slope of the flatline.
It wont do you much good since your working for absorbance but if you ever see something like a temperature change you can use the slope(s) to find freezing points/melting

How many electrons does potassium have in its outside electron shell?
Answer:
Potassium (K) is of atomic number 19 and has only 1 electron in the outermost shell
And this is because of the octet rule of chemistry followed while determining the number of electrons in each shell.
According to the octet rule, there can only be a maximum of 8 electrons in the outer shell of an atom, So when 'L' shell of K is filled with 8 electrons to accommodate the 19th electron a new shell will be created
