I think Sam is right because pond water can be full of impurities which can include many microorganisms such fungi, bacteria, protozoa, etc. For example, there is high possibility that the pond water sample collected by Sam and Carol would contain traces of blue-green algae which is also a living organism as it uses sunlight to prepare its own food.

does aerobic and anaerobic respiration have the same number of carbons, hydrogens and oxygens? Explain.
The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration.

Which of these is the direct result of an error in the transcription of a DNA nucleotide
Amino acids do not bond to tRNA.
The nuclear membrane is ruptured.
A codon sequence is incorrect.
Transportation of mRNA does not occur.
The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.
What is transcription?The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.
In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.
This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.
The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.
Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.

Which subatomic particle determines an element's atomic number?
Answer: protons
Explanation: atoms of each element contain a characteristic number of protons
Answer:
the answer is protons
Explanation: Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.
The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?
Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for 9 amino acids.
Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids

How is torque related to force?
Answer:
Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.

The oceans have become increasingly acidic in recent years as the water absorbs more and more carbon dioxide
from the atmosphere. This increased acidity interferes with the ability of corals to maintain their skeletons. In
addition, an increase in water temperatures worldwide is causing coral bleaching, another condition that threatens
the health of coral reefs.
Based on this information, which of the following would most improve the health of coral reefs?
Reducing the use of fossil fuels since they emit CO2 that reacts in water
CO2+H2O-->H2CO3
The following would most improve the health of coral reefs is reducing the use of fossil fuels.
What kills corals?One of the biggest threats to coral reefs is the so-called "coral bleaching", a process that leads to the death of hundreds of corals around the world. The phenomenon occurs when the temperature of the water increases, due to natural causes, such as El Niño, or caused by man, such as global warming.
Scientists have created a device that innovates the technique of transplanting corals from the recovery of fragments with tissue loss. The device works as a kind of cradle, where the fragments are kept until they recover and grow.

Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?
Answer:
Microvilli are typical of these cells. These projections increase the absorptive area on the cell surface.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. Their principal function is to absorb. The microvilli of the intestinal epithelium are very uniform in size and distribution.

Explanation:
The Devils Hole pupfish is one of the world's rarest fishes, spending most of its life in the top few meters of very warm waters of a cavern located in the middle of the Mojave Desert. Devils Hole,
a geologic pool, is the only naturally occurring habitat for the endangered Devils Hole pupfish. This fish's habitat is one of the smallest natural ranges known for any vertebrate. Devils Hole is an
extreme environment, with water temperatures and dissolved oxygen concentrations near the lethal limits for most fish species.
Which of the following statements best explains why the Devils Hole pupfish are able to live in this environment?
Answer:
Thermal invasive
Explanation:
Devils Hole pupfish can live in this environment because they have adapted genes, which offer resistance to their bodies to the harsh environment where they live.
We can come to this answer because:
A living being can only live in an inhospitable environment if its organism allows for an adaptation.In this case, we can say that Devils Hole pupfish had a population with different genetic compositions, where some had genes adapted to this environment and others did not have these genes.Devils Hole pupfish that didn't have the adapted genes didn't resist the environment and died.The Devils Hole pupfish that possessed the genes survived and passed those genes on to their descendants.In this case, Devils Hole pupfish that received the genes adapted to the environment developed resistance that allows them to live amidst extreme resources.
