Answer;
C. RuBP
Explanation;
The Calvin cycle reactions can be organized into three basic stages: fixation, reduction, and regeneration.
In the stroma, in addition to CO2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP).
Fixation stage; RuBisCO catalyzes a reaction between CO2 and RuBP, which forms a six-carbon compound that is immediately converted into two three-carbon compounds.
Reduction; ATP and NADPH use their stored energy to convert the three-carbon compound, 3-PGA, into another three-carbon compound called G3P.
Regeneration; One of the G3P molecules leaves the Calvin cycle to contribute to the formation of the carbohydrate molecule. The remaining G3P molecules regenerate RuBP, which enables the system to prepare for the carbon-fixation step. ATP is also used in the regeneration of RuBP.

Lipids are biomolecule, they also contain three atom carbon(C) hydrogen(H) oxygen(O) linked to glycerol.These are the long sequence of carbon to carbon with hydrogen bonds.Number of hydrogen is low and carbon number is high. Electronegativity between carbon and oxygen is high.Thus, they form lipid a non-polar long chain and they are insoluble in water.
Types of Lipids
• Simple
i. Wax
ii. Oil
iii. Fats
• Complex
i. Glycolipid
ii. Phospholipid
iii. Proteolipids
Function of Lipid
• Store energy
• Precursor for many hormones
• Metabolic fuel
• Part of the cell membrane
• Help in digestion.
Thus, carbohydrates are polar molecule and soluble in water. Lipids are non-polar molecule which is insoluble in water.

Why is the clear area surrounding an antibiotic disk called the zone of inhibition?
Answer:
No bacteria grows in surrounding area of antibiotic disk, thus it is known as zone of inhibition
Explanation:
The area surrounding an antibiotic disk is called the zone of inhibition because in this region bacteria & its colonies are unable to grow. Due to the anti microbial effect produced by bacteria, there is no visible sign of presence of bacteria in the inhibition region.
Also, the zone of inhibition also depicts susceptibility of bacteria towards the effect of antibiotics.

Final answer:
The change in the frequency of alleles from one generation to the next is the definition of evolution in population genetics. It refers to a change in the proportion of a specific allele within a population, relative to all other alleles of that gene.
Explanation:
The change in the frequency of alleles from one generation to the next is the definition of evolution in terms of population genetics. It refers to a change in the proportion of a specific allele within a population, relative to all other alleles of that gene. For example, in the ABO blood type system, the frequency of the IA allele can change over time, leading to evolution in the population. This concept is important in understanding how genetic change drives phenotypic change and adaptation in populations.

Which type of repair is a backup for the dna polymerase proofreading function?
Base excision repair is a backup for the DNA polymerase proofreading function.
Base excision repair (BER) in biochemistry and genetics refers to the cellular mechanism during the cell cycle that repair damaged DNA and it is mainly responsible for removing small, non-helix-distorting base lesions from the genome.
Mismatch repair is a backup for the DNA polymerase proofreading function.
Mismatch repair takes place immediately after the completion of the DNA synthesis and its job is to detect, remove and replace small insertions that were undetected during proofreading.
Further ExplanationThe enzymes that are responsible for the creation of DNA in cells are known as DNA polymerase. When DNA replication takes place, the DNA polymerase can check to know which bases are added. The DNA polymerase can discover if bases are impaired. This process is what is called Proofreading.
During DNA synthesis, the DNA polymerase can discover incorrect nucleotides and replace them accordingly before the continuation of the DNA replication.
Although many errors that occur during DNA synthesis are corrected by the polymerase, some errors can still go on undetected. However, some of these insertions can be detected and corrected through mismatch repair.
Mismatch repair is the process that involves detecting and corrections of erroneous insertion that can occur after DNA replication. DNA mismatch repair can as well detect and repair damages to the DNA after New DNA has been created. The major function of the Mismatch repair is to detect, removed and replaced bases that are mispaired.
Therefore, Mismatch repair is a backup for the DNA polymerase proofreading function.

a. photosynthesis, the atmosphere
b. volcanic eruptions, meteorites
c. photosynthesis, respiration
d. respiration, photosynthesis
e. respiration, rainfall
Oxygen enters the ocean only at the surface, from photosynthesis and the atmosphere.
The question pertains to how oxygen enters the ocean. Oxygen enters the ocean mainly from two sources: photosynthesis and the direct exchange with the atmosphere. Photosynthesizing organisms, such as algae and cyanobacteria, which are also referred to as phytoplankton, play a crucial role in this process by converting carbon dioxide and water into oxygen and organic compounds. Additionally, the oxygen from the atmosphere dissolves directly into the surface of the ocean through physical mixing processes.
The correct answer to the student's question is "(a). photosynthesis, the atmosphere." Photosynthesis by marine organisms adds oxygen to the ocean waters, while the atmosphere exchanges gases with the ocean's surface, allowing more oxygen to dissolve into the water.

The following seed phenotypes showed up in a generation of plants. Which alleles are recessive? blue round = 75 white round = 28 blue wrinkled = 24 white wrinkled = 8 blue and round white and round blue and wrinkled white and wrinkled
Answer:
blue and wrinkled are recessive.
Explanation:
Based on the given seed phenotypes, the alleles that are both recessive include: D. white and wrinkled.
What is a recessive trait?A recessive trait can be defined as a masked allele in the genotype which can only expressed by a living organism when two (2) of the same masked alleles are inherited.
In Genetics, the phenotypic ratio between the offspring of two (2) heterozygous parents within the F2 generation is equal to 9:3:3:1.
Given the following seed phenotypes:
Blue round = 75 = 75/9 ≈ (9 × 8).White round = 28 = 28/3 ≈ (3 × 8).Blue wrinkled = 24 = 24/3 ≈ (3 × 8).White wrinkled = 8 = 8/1 ≈ (1 × 8).Therefore, the phenotypic ratio between the offspring is close to 9:3:3:1 within the F2 generation.
Note: 1 represents the number of phenotypes with both recessive traits.
In conclusion, we can logically deduce that white and wrinkled are the alleles that are both recessive.
