The missing enzyme is DNA polymerase.
DNA replication is a complex process that involves the duplication of the DNA molecule in a cell. One of the key enzymes involved in this process is DNA polymerase, which catalyzes the formation of new DNA strands by adding complementary nucleotides to the existing template strand.
In a cell where replication bubbles form and RNA primers are present but no DNA replication takes place, the absence of DNA polymerase is the likely cause. DNA polymerase is responsible for elongating the RNA primers and synthesizing the new DNA strand during the replication process. Without this enzyme, the replication process cannot proceed, and DNA replication stalls.
RNA primers are short sequences of RNA that provide a starting point for DNA synthesis during replication. They are necessary because DNA polymerase can only add nucleotides to an existing strand and cannot initiate DNA synthesis on its own. Instead, it requires a primer, which is usually made of RNA, to start the process.
If DNA polymerase is missing or non-functional, the RNA primers cannot be extended, and DNA replication cannot occur. This can lead to various replication errors and the formation of incomplete DNA strands, ultimately affecting the stability and integrity of the cell's genetic material.

Based on your experimental results, categorize each microbe as preferring isotonic environments, being halotolerant, or as a halophile.
The microbes present in the experiment were:
S. cerevisiae
S. epidermis
A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.
If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:
S. cerevisiae only grows when it is in a 1% solution.S. epidermis only grows when it is in a 1% and 7% solution.
In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

5.8 L
4.0 L
Answer:
(1) 9.0 L (3) 5.8 L
(2) 6.2 L (4) 4.0 L
None
Explanation:
A cylinder with a movable piston contains a sample of gas having a volume of 6.0 liters at 293 K and 1.0 atmosphere, the volume of the gas sample is approximately 6.2 L. The correct option is B.
What is combined gas law?The combined gas law is a gas law that combines Charles's law, Boyle's law, and Gay-Lussac's law. It relates the pressure, volume, and temperature of a gas in a closed system.
Using the combined gas law:
(P1 × V1)/T1 = (P2 × V2)/T2
where P = pressure, V = volume, and T = temperature.
Given:
P1 = P2 = 1.0 atm
V1 = 6.0 L
T1 = 293 K
T2 = 303 K
Solving for V2:
(1.0 atm × 6.0 L) / 293 K = (1.0 atm × V2) / 303 K
V2 = (1.0 atm × 6.0 L × 303 K) / (293 K × 1.0 atm) ≈ 6.2 L
Therefore, the volume of the gas sample is approximately 6.2 L after heating to 303 K while maintaining a pressure of 1.0 atm. The answer is option (B) 6.2 L.

Which of the following best describes The change in the percent of penicillin-resistant S. Aureus bacteria since 1940
According to the information provided in the graph it can be inferred that the percent of resistant S. aureus doubled from 1950 to 1960.
The graph shows the evolution of the resistance of the Streptococcus aureus bacteria to penicillin from 1940 to 2010. The percentage of resistance evolved as follows:
1940 - 0% 1950 - 40% 1960 - 80% 1970 - 83% 1980 - 88% 1990 - 90% 2000 - 97% 2010 - 100%
According to this information, it can be inferred that the correct answer is option B because the percentage of resistance of S. aureus doubled from 1950 (40%) to 1960 (80%). Additionally, the other options are not because:
A. Between 1980 and 2010, resistance growth was lower than in previous years. C. Resistance peaked in 2010 (100%). D. Loading capacity was reached in 2010.

Two descriptions about physical quantities are given below:
Quantity A: It is a force.
Quantity B: It changes when the object travels from Earth to Earth's moon.
What quantities are these most likely describing? (4 points)
A. Both Quantity A and Quantity B are mass.
B. Both Quantity A and Quantity B are weight.
C. Quantity A is weight and Quantity B is mass.
D. Quantity A is mass and Quantity B is weight.
Answer:
I would base my answer on the choices. There are only two parameters mentioned: mass and weight. Mass is constant regardless of the the location. So, definitely it is neither Quantity B nor Quantity A. Weight, on the other hand, is a consequence of gravitational force. Since gravity is different in the moon and the Earth, weight varies. Thus, the answer is B.
After transcription and translation, does the mutation that was in the DNA change the amino acid that the second codon specifies?
Given what we know about genetic mutation, we can confirm that unless the mutation is of the silent type (and sometimes regardless of this), it will in fact change the amino acid that the codon specifies.
Mutations are changes in the DNA sequence of a cell that occur during the replication phase. Cellular mutations can be of many types, such as:
Insertion DeletionSubstitutionInversionand so on, each of which can have varying effects on the amino acid produced.
Most mutations will affect the resulting amino acid in some way. Insertion and deletion tend to be the most harmful mutation types as they alter the way in which the genetic code is processed. Some mutations, however, can be silent, meaning they have no harmful effects due to the fact that the new sequence either encodes the same amino acid or one with a similar enough function. This is possible through mutations like substitution.
Substitution mutations change one nucleotide in a sequence for another. At times, the new sequence will actually encode for the same amino acid as before despite the change. This is one of the only situations in which the amino acid will not be changed. Most often, if a mutation occurs, we can expect the resulting amino acid to change.

Explain the process of digestion in human
Answer:
Humans have holozoic nutrition, that means the food is consumed as a whole and the digestion occurs internally. It can be described as:
1. Ingestion of food- The food is taken in the oral cavity in the process called the ingestion. The teeth help in grinding of the food, salivary amylase helps in partial breakdown of the starch and the tongue helps in mixing the food with saliva and helps in swallowing it. The food is now called bolus.
2. Digestion- The process of break-down of complex substances into simpler substances is called digestion and it starts with the mouth where physical break-down occurs along with some chemical digestion. The bolus is swallowed in and it arrives in stomach where the digestion of proteins occurs due to presence of the enzyme pepsin. Bolus is now called the chyme. This chyme now moves into the small intestine where rest of the process of digestion will be completed. The pancreatic juice, the intestinal juice and the bile will result in breakdown of carbohydrates, fats and the rest of the proteins. The chyme is now called the chyle and it moves to the large intestine where the water is absorbed.
3. Absorption- The digested food is absorbed via the finger-like projections present on the inner surface of the small-intestine and the reach the blood stream.
4. Assimilation- The absorbed food is then used by different tissues for the energy generation. The excess food is stored as glycogen in the liver and s fats in adipose tissue.
5. Excretion- The undigested material passes from the small-intestine to the rectum of the large-intestine, from where it is removed from the body through anus.
