Latitude measures how far a point is north or south of the equator. Since the earth is round, distance from the equator is measured in angular degrees with the equator being 0 degrees and the northernmost point -- the North Pole -- being at 90 degrees. The southernmost point -- the South Pole -- is also at 90 degrees.<span>Latitude is measured in degrees north when in the northern hemisphere and degrees south when in the southern hemisphere.
Hope this helps. :)</span>
A bacterium has a faulty lac operon in which there is a structural defect in the operator. In this bacterium there is a structural problem with a segment of DNA that binds a repressor.
- A protein known as a repressor binds to an operator site. The operator in this instance (and numerous others) is a section of DNA that lies just downstream of the RNA polymerase binding site or overlaps with it (promoter). In other words, it lies between the operon's promoter and its genes.
- The repressor protein inhibits the synthesis of messenger RNA by attaching to the promoter region of the gene(s) (mRNA). The control of gene expression in cells requires repressor proteins.
- Thus, by physically impeding the RNA polymerase's ability to operate, these repressor proteins stop the gene from being transcribed.

Answer:
a.glycolysis d.acetyl CoA b.citric acid cycle e.electron transport chain
Explanation:
Cellular respiration is set of metabolic processes that occur within the cell in order to produce usable energy (ATP) from the nutrients (food). It can be divided into four main stages:
- Glycolysis-anareobic process in which glucose is broken down and it occurs in the cytoplasm. Products of glycolysis are 2 molecules of pyruvate and 2 molecules of ATP.
- Transition- Pyruvate form the glycolysis is transported into the mitochondria, where it is converted to a molecule Acetyl CoA used for further breakdown
- Citric acid cycle or Krebs cycle- aerobic process that occurs in the mitochondria matrix in which 4 molecules of ATP, and NADH are produced
- Electron transport chain-set of reactions that occur within the cristae of mitochondria. NADH and electrons are passed through electron transport chain to result in the production of ATP (32 ATPs for every glucose).
Answer:
glycolysis
Explanation:
Glycolysis uses glucose to create ATP within the cytoplasm of the cell.
