Answer:
A) True
The polarity of water is what makes it an ideal transport vehicle for nutrients and micronutrients that are water-soluble. Within organisms, water can be used to transport nutrients and even waste from one part of the body to the other. In the case of humans, urine is used to get rid of soluble waste from within the body.
B) True
During the process of photosynthesis, carbon dioxide (CO2) and water (H2O) are taken from the air and soil respectively. Oxygen is able to produce water when it is reduced. Hydrogen during this process is oxidized.
C) False
Ice floats on water. Hence it cannot be denser than water. Rather, water is denser than Ice. Because of the structure of hydrogen bonds, when they are iced, the bonds tend to pull apart, thus making ice expand somewhat. This expansion creates microscopic pockets of air in the molecules thus given them buoyancy.
D) True (X)
E) True (X)
F) True
Heat Capacity refers to the amount of heat a substance like water can absorb before it's temperature rises by 1 degree. This property is important, because, were it not for the high specific heat capacity of water, many people and plants would have boiled over.
G True (X)
Heat of vaporization is the kind and amount of energy required to alter one gram of liquid into a gas at boiling point

Two pea plants with purple flowers are crossed. Among the offspring, 63 have purple flowers, and 17 have white flowers. With a chi-square test, compare the observed numbers with a 3:1 ratio and determine if the the difference between observed and expected is statistically significant. Note: Chi-square critical value with 1 degree of freedom is 3.84 with alpha equal to 0.05
Answer:
Chi-square value = 0.6
The difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis.
Explanation:
H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
• Chi square= ∑ ((O-E)²/E)
∑ is the sum of the terms
O are the Observed individuals
E are the Expected individuals
• Freedom degrees = 1
• Significance level, 5% = 0.05
• Table value/Critical value = 3.84
The number of observed individuals:
63 have purple flowers, 17 have white flowersTotal number of individuals, N = 80 = 63 + 17
Observed Genotypic frequencies:
F(PF) = 63/80 = 0.79F(pf) = 17/80 = 0.21p² + 2pq + q² = 1
p² + 2pq = F(PF)
0.79 + 0.21 = 1
The expected genotypic frequency:
F (PF)= 0.75
F (pf) = 0.25
The number of expected individuals:
PF= 0.75 x 80 = 60 wf = 0.25 x 80 = 20Chi square = sum (O-E)²/E
PF = (O-E)² /EPF =(63 - 60) ² / 60
PF = 0.15
pf = (O-E)² /Epf= (17 - 20)²/20
pf= 0.45
Chi square= sum ((O-E)²/E) = 0.15 + 0.45 = 0.60
Chi square = 0.6Degrees of freedom = 1 alpha 0.05 Table value/Critical value = 3.840.6 < 3.84 meaning that the difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis. Probably both parentals were heterozygous for the trait.

Suppose you are given an unknown solution and you need to test its pH. The pH meter is broken, and all you have is the indicator bromothymol blue to use. You add two drops of bromothymol blue to 10 mL of your unknown, and the solution turns a bright yellow. Which of the following is the best estimate of the pH of the unknown solution?
a. 8.5
b. 11.5
c. 1.5
d. 7.0
Answer: The best estimate of the pH of the unknown solution is 1.5. Option C.
Explanation:
A substance which shows different colours in acidic and basic media is called an indicator. Typical examples of common indicators includes:
--> Litmus: colour in acid ( red), colour in base (blue) and colour in neutral (purple).
--> Methyl orange: Colour in acid (red), colour in base (yellow) and colour in neutral (Orange).
--> Phenolphthalein: Colour in acid (colourless), colour in base (pink) and colour in neutral (colourless).
--> BROMOTHYMOL BLUE: Colour in acid ( yellow), colour in base (blue) and colour in neutral (green).
The indicators are themselves weak organic acids or bases and hence slightly dissociated in solution. The colour of the indicator at any given point depends on the relative proportion of the dissociated ions to the undissociated molecules since they have different colours.
From the question, since the pH meter is broken, and the pH of the unknown solution is to be determined,using an indicator instead. The best estimate of the pH of the unknown solution is 1.5. This is so because BROMOTHYMOL BLUE is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and yellow when the pH is less than 6. And pH value of 1.5 is less than 6, indicating the solution is very acidic.

Which of the following statements describes a way in which bacteria differ from animals and plants?
The BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.
Prokaryotic cells (i.e. bacteria and Archea) have no nuclei and lack organelles.In these cells (prokaryotic cells), the genetic material consists of a single circular chromosome localized in a region of the cytoplasm called the nucleoid.On the other hand, eukaryotic cells (e.g., plant cells and animal cells) have their genetic material delimited by a membrane-bound organelle known as the cell nucleus. Moreover, eukaryotic cells also have different types of membrane-bound organelles that carry out specialized functions in the cell (e.g., mitochondria, chloroplasts, Golgi apparatus, vacuoles, etc).In conclusion, the BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.

quizleet Using the information in the introduction on mutations and your knowledge of proteins, develop a hypothesis to explain how the changes in the MC1R protein amino acid sequence might affect its function.
Answer:
Dark colour occurs.
Explanation:
The amino acid changes in the MC1R protein may change the structure and function of the protein because the amino acids are the building blocks of proteins. This change in amino acid leads to increased production of eumelanin, which results in the dark color of the protein. So we can say that change in the amino acids leads to the change in the structure and function of MC1R protein.

A: Living organisms use energy from the sun and water to create food in the form of sugar.
B: Living organisms take in oxygen and water to create food in the form of sugars and energy.
C: Living organisms breakdown sugar from food to combine with oxygen making usable energy
D: Living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.
Answer:
C. Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Explanation:
Cellular respiration is about making food into energy. Since C is the only one with that aspect C can be the only answer.
The statement which best explains the general process of cellular respiration is: C: Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Cellular respiration can be defined as a series of metabolic reactions which typically occur in living cells, so as to produce energy in the form of adenosine triphosphate (ATP).
Generally, high energy intermediates that can then be oxidized to make adenosine triphosphate (ATP) are created during cellular respiration.
Basically, the general process involved in cellular respiration can be represented by a single equation while using the following substances;
Glucose (Sugar).Oxygen.Carbon dioxide.Water.Adenosine triphosphate (ATP).[tex]Glucose + Oxygen ---> Carbon \;dioxide + Water + ATP[/tex]
In conclusion, all living organisms breakdown sugar or glucose from their food to combine with oxygen, so as to make usable energy during cellular respiration.
