Fermentation can only take place in an anaerobic environment because yeast is relatively anaerobic. When there is oxygen present, yeast engages in aerobic metabolism.

Yeast fermentation: When oxygen is present, yeast engages in aerobic respiration, converting carbohydrates (a source of sugar) into carbon dioxide and water. In the absence of oxygen, yeast ferments carbohydrates and produces carbon dioxide.

Through the process of electron transfer and oxygen, yeast mitochondria regenerate NAD+. Alcohol and CO2 are created during the fermentation process, which essentially only takes place in the absence of oxygen (resulting in carbonation). The roommate left the bucket open to the air, which provided the yeast with an ongoing supply of oxygen.

The correct option of the given statement "Biological catalysts that increase the rates of biochemical reactions are known as" is enzymes.

Enzymes are proteins that accelerate the rates of biochemical reactions. They act as biological catalysts, increasing the reaction rate without affecting the chemical reaction's thermodynamics (the free energy change). It hastens the rate of a reaction by reducing the activation energy necessary for the reaction to occur.

Enzymes are highly specific, with each enzyme catalyzing only one reaction or a group of closely related reactions. Inhibitors are compounds that inhibit or slow down the enzyme's activity, while substrates are compounds that are transformed into products by enzymes.

Answer:

I believe that the smallest is Nucleotide, bases, genes, DNA, Chromsomes.

Explanation:

1. Based on the Punnett square, the number of short-haired offspring and long-haired offspring can be determined by counting the respective combinations of alleles.

2. There is a possibility of pure breed (homozygous) short-haired offspring in the cross if both parent organisms contribute the short-haired allele.

1. Based on the Punnett square, we can determine the potential number of short-haired and long-haired offspring. Let's assume that "S" represents the dominant allele for short hair and "s" represents the recessive allele for long hair. If both parents are heterozygous (Ss), the Punnett square would look like this:

S        s

S SS Ss

s Ss ss

From the Punnett square, we can see that there are three possible genotypes: SS, Ss, and ss. The SS and Ss genotypes correspond to short-haired offspring, while the ss genotype corresponds to long-haired offspring.

Therefore, based on the Punnett square, 75% of the offspring (3 out of 4) may be short-haired, while 25% of the offspring (1 out of 4) may be long-haired.

2. There will not be a pure breed (homozygous) short-haired offspring in this cross. A pure breed (homozygous) short-haired offspring would have the genotype SS. However, in the given cross, both parents are heterozygous (Ss). This means that each parent carries one copy of the dominant allele (S) and one copy of the recessive allele (s).

When the parents are crossed, the possible genotypes of the offspring are SS, Ss, and ss. As we can see from the Punnett square, the genotype SS is not possible as there is no parent that contributes the recessive allele (s) to create a homozygous short-haired offspring.

Therefore, all the short-haired offspring in this cross will be heterozygous (Ss), carrying one copy of the dominant allele (S) and one copy of the recessive allele (s).

Gel electrophoresis is a widely used technique in molecular biology that allows for the separation of DNA fragments based on their size and charge.

The process involves several steps:

Preparation of the gel: A gel matrix, usually made of agarose or polyacrylamide, is prepared and poured into a gel tray. Small wells are created at one end of the gel, which will hold the DNA samples.

Loading the samples: DNA samples, which have been treated with restriction enzymes to generate fragments of different sizes, are loaded into the wells of the gel.

Applying an electric field: The gel tray is immersed in a buffer solution, and an electric field is applied across the gel. One end of the gel serves as the positive electrode (anode), and the other end as the negative electrode (cathode).

Migration of DNA fragments: When the electric field is applied, negatively charged DNA fragments migrate through the gel towards the positive electrode. Smaller fragments move more quickly through the gel matrix, while larger fragments move more slowly.

Visualization of DNA bands: After the electrophoresis is complete, the DNA fragments are visualized using stains or fluorescent dyes. The bands formed on the gel represent the separated DNA fragments, with each band corresponding to a specific size.

By analyzing the position and intensity of the DNA bands, researchers can determine the size of DNA fragments and gain insights into various genetic phenomena, such as gene mapping, DNA sequencing, and genetic variation analysis.

The 6 steps of the  lysogenic cycle are described bellow, these are:

The lysogenic cycle is one of the two replication cycles employed by bacteriophages, which are viruses that infect bacteria. In the lysogenic cycle, the bacteriophage's genetic material is integrated into the host bacterium's DNA, and the phage DNA replicates along with the bacterial DNA during cell division. The key steps of the bacteriophage replication process in the lysogenic cycle are as follows:

Attachment: The bacteriophage attaches to a specific receptor on the surface of the host bacterium, using its tail fibers or other surface proteins. This attachment is essential for the phage to infect the bacterium.

Penetration: The phage injects its genetic material, either DNA or RNA, into the host bacterium through the cell wall and membrane using its tail or other specialized structures. The phage genetic material takes over the host bacterium's cellular machinery.

Integration: The phage genetic material becomes integrated into the host bacterium's DNA. It is often inserted into a specific site in the bacterial genome, and this integrated phage DNA is known as a prophage.

Replication: The integrated phage DNA is replicated along with the host bacterium's DNA during bacterial cell division. As the host bacterium multiplies and divides, the phage DNA is also replicated, and the progeny cells carry the phage DNA.

Lysogenic state: The host bacterium continues to grow and divide, and the phage DNA remains integrated in its genome. The bacterium, now called a lysogen, can pass on the integrated phage DNA to its progeny cells, allowing the phage DNA to be replicated in subsequent generations without causing immediate harm to the host bacterium.

Induction: Under certain conditions, such as environmental stress or changes in the host bacterium's physiology, the prophage may be induced to enter the lytic cycle. This triggers the production of new phage particles, and the host bacterium is ultimately lysed (destroyed) to release the newly formed phages.
