During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate. A charged phosphate group is added to this molecule during the phosphorylation of glucose by glucokinase. Since G6P is unable to permeate the cell membrane, unbound glucose cannot diffuse out of the cells. Hepatocytes can capture glucose because of the phosphorylation step that is made possible by glucokinase.

In a pecie of fly, mooth wing (W) are dominant to wrinkled wing (w) and red bodie (R) are dominant to yellow bodie (r). A WwRr and wwrr fly mate and produce the following offpring:
Phenotype Number of Offpring
Smooth, red 778
Smooth, yellow 162
Wrinkled, red 158
Wrinkled, yellow 785
What i the percent recombination frequency for thi cro?
Round to nearet whole number. \%%
The percent recombination frequency of the offspring produced by the cross between WwRr and wwrr fly will be approximately 17%.
Recombination frequency is the proportion of the recombinant offspring (whose trait is different from the parents) produced by a cross.
It can be calculated by the formula: (Total number of recombinant offspring / total number of offspring produced ) × 100.
In the question, the trait of parents is: smooth and red (WwRr) and wrinkled and yellow (wwrr).
Therefore, offspring having trait combinations other that this are recombinants. Thus the total number or offspring will be:
Smooth, yellow + Wrinkled, red = 162 + 158 = 320.
The total number of offspring produced by the cross are: 778+162+158+785 = 1883.
Therefore, the percentage recombination frequency = (320÷1883) × 100 = 16.99 %.
The nearest whole number to this value is 17 %.

Household vinegar advances the fight against crown of thorns starfish threat on Great Barrier Reef
ABC North Qld
By Kathleen Calderwood and Isobel Roe
Crown of thorns starfish (COTS) is a pest which eats coral tissues, posing a huge threat to the reef. Australian
Institute of Marine Science research showed coral cover on surveyed reefs had declined by about 50% over
the past 30 years, with COTS responsible for almost half of that decline. James Cook University scientist Lisa
Boström-Einarsson searched for an eradication method for COTS that was cheap, easily available and safe
for everything other than the starfish themselves. Her method involved injecting the COTS with 20 milliliters
of household vinegar. The trial saw a 100% kill rate within 48 hours of injection. "I tried alcohol [first] and that
did not work very well, and then I heard some rumors that some people had used vinegar but had not had
very good results," Ms Boström-Einarsson said. "So I refined the methods a little bit and then it turned out to
work really well." Ms Boström-Einarsson said the starfish were mostly water inside and could not tolerate the
acidity of the vinegar. "The acid basically just melts their insides," she said. "It is quite dramatic the way they
go and within 24 hours there is basically just slime left-it is not pretty."
Explain the scientific procedure followed in the article by describing the following: (4 points)
1. State the problem
2. Identify a hypothesis from the article
3. Identify the procedures used in the experiment
4. Describe the results
1. State the problem: This COTS pest destroys coral tissues, endangering the reefs severely. Marine Science investigated the matter and discovered that COTS was to blame for the coral cover on measured reefs declining by around 50% during the previous 30 years.
2. Identify a hypothesis from the article: If Lisa succeeds in eliminating COTS, the COTs may begin to perish.
3. Identify the procedures used in the experiment: So Lisa looked for a COTS eradication approach that was affordable, simple to apply, and safe for all organisms except starfish. She utilized alcohol and vinegar because it was convenient and affordable.
4. Describe the results: Lisa initially tried using alcohol, but she soon realized that it did not work. After hearing reports that other people had used vinegar, but had received poor results, Lisa slightly improved the procedures, which eventually proved to be quite effective. After all, it was determined that because starfish were primarily made of water, they could not withstand the acidity of the vinegar. As a result, the starfish were killed within 24 hours, leaving only slime.
What is COTS?
Acanthaster planci, often known as the COTS, is a type of corallivore that lives naturally on coral reefs and consumes coral polyps. They come in a variety of colors, from reddish-gray to green to purplish blue, and are covered in long, venomous spines. Although they can be as huge as 80 cm, they typically have a diameter of 25 to 35 cm.
COTS are an essential component of the ecosystem in normal proportions on healthy coral reefs. They frequently consume the rapidly corals, allowing the slower-growing types to catch up and increasing the variety of coral reefs on our reefs.

During the relative refractory period, the membrane is hyperpolarized and a larger incoming stimulus is required to trigger an action poential. How does this affect the response properties of a sensory neuron?.
The pace at which the sensory neuron emits action potentials will rise with increased input intensity.
How can hyperpolarization of a membrane affect it?A cell's membrane potential changes during hyperpolarization to become more negatively charged. It is a depolarization's opposite. By requiring more stimuli to raise the membrane potential to the action potential threshold, it prevents action potentials.
Some potassium channels remain open throughout the hyperpolarization period, whereas sodium channels reset. Before the potassium channels shut, there is a period of enhanced potassium permeability, which causes an excessive potassium outflow. This leads to hyperpolarization, which is seen by the tiny drop that follows the spike.
The membrane potential becomes marginally more positive than its resting value as a result of the increased outflow of potassium ions.

Thаt is, regаrdless of whether the pollen wаs from а leаf thаt wаs green, vаriegаted or white. If the femаle flower cаme from а region where the leаves were green, аll the progeny were green. Similаr results were seen when the femаle wаs from а region on the plаnt where the leаves were either vаriegаted or white. In compаrison to trаits controlled by mаternаl effects, those trаits controlled by mаternаl inheritаnce, the femаle phenotype is аlwаys expressed in its offspring.
