17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.
Answer:
It is B
Explanation:
I had this question on my test last week
The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).
An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.The linear sequence of amino acids within a protein is the primary structure of proteins. The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.The most common tertiary structures of the proteins are globular and fibrous structures.Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

a cell was poisoned by a substance that destroyed all of its mitochondria. which cell transport processes would be able to still continue?
Answer:
Nothing
Explanation:
If a cell's mitochondria were destroyed it would die. Mitochondria are the power houses of the cell and without energy, necessary reactions could not take place .
If a mitochondria stopped working the cell would not have its respiratory function such as to use carbon dioxide, water, and energy in which the cell needs to survive so the cell would eventually stop moving and slowly die out with no nutrients and energy.

Describe how the process of natural selection can result in an increase in frequencies of certain traits found in a population.
Answer:
Natural Selection (Answer Below)
Explanation:
Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability

Which of the following statements is true?
A.
Chemical reactions can only absorb thermal energy.
B.
Chemical reactions can neither absorb thermal energy nor release thermal energy.
C.
Chemical reactions can either absorb thermal energy or release thermal energy.
D.
Chemical reactions can only release thermal energy.
Answer: C. Chemical reaction absorb or release thermal (and sometimes other) energy
Explanation:
Chemical reactions can result in products with more or less chemical energy than the precursors. When products have less chemical energy, the excess is converted to heat (exothermic reaction)
When the products have more chemical energy, heat must be added to make up the difference (Endothermic reaction)
Fireworks are examples of exothermic reactions where the excess is released as thermal, mechanical, and radiant energy. A lit match releases thermal and radiant energy.
Respiration is also an exothermic reaction
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy
Respiration is the reverse of photosynthesis, an endothermic process. The overall photosynthetic reaction is 6CO2 + 6H2O + energy —> 6C6H12O6 + 6O2
In this case radiant energy drives the reaction.
The reaction 2H2O —> 2H2 + O2 is an endothermic reaction driven by electrical energy.
Many reactions are reversible and if one is endothermic, the reverse is exothermic e.g. 2H2 + O2 —> 2H2O +energy is the reverse of electrolysis of water, or respiration vs photosynthesis.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

13) When mRNA is "processed", what are the pieces of mRNA that are cut out and stay in the nucleus?
Introns
Exons
Answer:
Introns
Explanation:
The coding region of the gene is the part of the gene that is transcribed. However, not all of the gene makes the final mRNA. There are sequences called exons and introns in the coding region of the gene.
The pre-mRNA contains transcribed sequences of both the introns and exons. However, the introns are removed from the final mRNA by splicing. The final mRNA that is translated to the protein only contains exons. An illustration is attached to illustrate this.

The correct statements for amino acids but not for sugars are :
C. typically contain nitrogen
E can bond together to form proteins
Explanation:
Both Sugars and amino acids always contain carbon molecules and both macromolecules can provide energy so are the source of the energy. Sugar molecule more specifically glucose molecule enters glycolysis during the cellular respiration process.
Amino acids always contain the nitrogen molecule in the structure along with carbon, oxygen, and hydrogen, there is a side chain present. Amino acids are the building blocks of the protein, peptide bonds are formed by amino acids together to make a poly peptide chain of a protein molecule.
1. Luca made the following chart for Earth's four basic movements, what needs to be correct on his chart?
Rotation Speed Revolution Speed Solar System Speed Milky Way Speed
0.3 miles/sec
18.5 miles/sec
370 miles/sec
150 miles/sec
The rotation speed and revolution speed should be switched
The revolution speed and solar system speed should be switched
The rotation speed and Milky Way speed should be switched.
The solar system speed and Milky Way speed should be switched.
Answer:
The solar system speed and Milky Way speed should be switched.
Explanation:
The speed of the Earth is with respect to how it moves around it's own axis (rotation speed), the Sun (revolution speed), solar system (solar system speed), and the milky way galaxies (milky way speed) etc.
According to this question, Luca made a chart for this Earth's four basic movements. The chart with their respective speed are as follows:
Rotation Speed - 0.3 miles/sec
Revolution Speed - 18.5 miles/sec
Solar System Speed - 370 miles/sec
Milky Way Speed - 150 miles/sec
Luca, however, made a mistake in his chart.
- The rotation speed of the Earth around its axis is correctly 0.3miles/sec
- The revolution speed of the Earth around the sun is correctly 18.5 miles/sec
- The solar system speed of the Earth i.e. around the solar system is about 150miles/hour
- The milky way speed of the Earth i.e. around local group of galaxies is about 370miles/hour.
Based on the comparison of Luca's chart and correct speed illustration, THE SOLAR SYSTEM SPEED AND MILKY WAY SPEED SHOULD BE SWITCHED.
