A biologist is studying a population of zebras that seems to be suffering from a disease that debilitates their bones. He
collects a sample of bones from the carcass of a deceased animal. He finds that the bones have a mass of 7.15
grams and occupy a volume of 5.5 cubic centimeters. What is the density of the bones?
O 1.0 g/cm
O 1.3 g/cm
O 1.8 g/cm
O2.0 g/cm
Answer:
1.3 g/cm
Explanation:
ok so to get this answer what you need to do is look at the cubic centimeters and contrast it with the grams
Answer:
b) 1.3 g/cm3^

Consider the denaturation equilibrium between native Ribonuclease A and unfolded protein. Ribonuclease A is a 124 amino acid protein with four disulfide bridges. To test the importance of one of the disulfide bridges in protein stability, residues Cys58 and Cys110 were mutated into Ala. The protein denaturation parameters for Ribonuclease A wild-type and mutant are shown below. All values are in kJ/mol.
wt: ΔH: 297.2
TΔS: 254.6
ΔG: 42.4
mutant: ΔH: 184
TΔS: 183.2
ΔG: 0.8
Mark the following statement as True or False: Denaturation is spontaneous for both enzymes.
A. True
B. False
Answer:
False
Explanation:
We know from thermodynamics that;
When ∆G is positive the process is not spontaneous
When ∆G is negative the process is spontaneous
When ∆G is zero, the system has attained equilibrium.
In both cases, ∆G is positive hence the denaturation of both enzymes is not spontaneous, hence the answer above.
Which greenhouse gas is produced by commercial refrigeration and air conditioning systems?
A. Carbon Dioxide
B. Fluorinated Gas
C. Nitrous Oxide
D. Methane
Answer:
B. Fluorinated Gas
ok
Air conditioners and fridges involves greenhouse gases which are hydrofluorocarbons. In commercial refrigeration and air conditioning systems carbon dioxide gases is produced.
What is greenhouse gas?Greenhouse gases trap heat in atmosphere and warm the Earth.
The main gases involved are carbon dioxide, methane, nitrous oxide, water vapors etc. It also involves flourinated gases.
Carbon dioxide is primary greenhouse gas, which is emitted by human activities.
Thus, option A is correct.

Match the transposition pathway with its correct description. Answers may be used more than once or not at all.
1. Retrotransposon pathway
2. Direct cut pathway
3. Cut and paste pathway
4. Replicative pathway
Transcription pathway
A. Involves removing a segment of DNA and placing it in a new location; the number of TE is not increased.
B. Involves the copying of DNA.
C. Involves the translation of proteins.
D. N/A E. Involves an RNA intermediate and the reverse transcriptase enzyme
Answer:
1. Retrotransposon pathway: E. Involves an RNA intermediate and the reverse transcriptase enzyme
3. Cut and paste pathway: A. Involves removing a segment of DNA and placing it in a new location; the number of TE is not increased.
5. Transcription pathway: B. Involves the copying of DNA.
4. Replicative pathway: C. Involves the translation of proteins.
2. Direct cut pathway: D. N/A
Explanation:
Class I transposable elements (also known as retrotransposons) are genetic mobile elements that copy and paste into other loci by reverse transcription and integration of the cDNA into new genomic regions
Class II transposable elements (also known as DNA transposons), can move by two different mechanisms of transposition:: 1-cut-and-paste pathway: the DNA transposon leaves one locus and integrates into another genomic site. and 2-replicative pathway: the DNA transposon remains in one locus while new copies of its sequence are mobile. The replicative pathway requires a transposase enzyme that acts as a catalyst of transposition.
Why are decomposers essential to a balanced ecosystem?
Answer:
Decomposers are like the housekeepers of an ecosystem. Without them, dead plants and animals would keep piling up with the nutrients the soil needs trapped inside. Decomposers clean up the dead material by processing it and returning the nutrients to the soil for the producers.
Describe what happens when an enzyme is placed in
environments that have different pH levels or
temperatures than its regular environment.
Answer:
If your just looking for the "why" then this is what i do know about it.
Explanation:
Changes in pH cause amino acids' component atoms and molecules to ionize. This can make an enzyme change shape. These shapes determine function, so changing the shape can impair the enzyme's function, preventing it from speeding up chemical reactions.
Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . Enzymes therefore work best at a particular temperature.
Hope this helps.
this is responsible for providing shape to the cell

3. Plants have properties that make them practical source of foods. Which
property make them good source of foods?
A, resistance
B, mechanical C. chemical
D. physical
Answer:
C
Explanation:
The property of plants that makes them a good source of food is the chemical property.
Plant lock-up energy in them in the form of carbohydrate which is derived from the process of photosynthesis. The energy from the sun is converted into chemical energy and when plant-consuming organisms feed on them, the chemical is broken down and the energy is released for the metabolic activities of the body.
These two processes can be expressed as equations:
1. [tex]6CO_2 + 6H_2O + energy --> C_6H_1_2O_6 + 6O_6[/tex]
2. [tex]C_6H_1_2O_6 + 6O_6 --> 6CO_2 + 6H_2O + energy[/tex]
The correct option here is C.
This has a lot of points and I am m giving out brainliest to anyone !! Please help me guys!
Answer:
C
Explanation:
Chloroplasts are necessary for plant cells to get energy. Plants are autotrophs, which means that they need to make food/energy by themselves to survive, and plants do so using a process called photosynthesis that chloroplasts aid in. Both plant and animal cells have a nucleus, cell membrane, and mitochondria, but only plant cells have chloroplasts. Therefore C.

Which is the property of nonmetals to evaporate easily?
brittle
dense
liquid
volatile
Volatile is the property of nonmetals to evaporate easily. The correct option is D.
What is being volatile means?The ease with which a material vaporizes is described by its volatility. A volatile material is defined as
A compound that readily evaporates at normal temperatures.One with a measurable vapor pressure. Basically, the term volatile refers to liquids.Volatility is a substance quality in chemistry that characterizes how easily a material vaporizes.
An active ingredient with high volatility is more likely to exist as a vapor at a given temperature and pressure, whereas a substance with low volatility is more likely to exist as a liquid or solid.
The enthalpy of vaporization describes the temperature dependence of the vapor pressure, while vapor pressure is the physical property that conveys a compound's volatility at a given temperature.
Thus, the correct option is D.
