It was the big day; Lance had been training for months in anticipation of the annual “Dasher Twenty-Six-Two.” As he laced up his sneakers, he thought back to the endless grind of aerobic training he had accomplished. Hour after hour of lung-burning, quad frying jogging on pavement and dirty. He was ready mentally and physically, plus he had a secret weapon ready to go. Lance had been experimenting in the use of a thick, sugar saturated gel-nutrition to supplement his running. He anticipated finishing just before the three-hour mark and he planned to eat his special goo around hour two for a much-needed energy boost. The goo solution was a mixture of maltose, sucrose, and glucose, as well as some salt. Water would be available on the course every few miles and with his nutrition plan set he found his way to the line. *BOOM*

The start gun leaked smoke as wave after wave of runner set off. Miles started flowing by… five miles feeling good… Mile thirteen halfway there! Just as the two-hour mark was upon him, Lance pulled the gel from his pocket and slurped the gooey syrup down. Mile fifteen Phew, heavy legs… Mile eighteen Legs are burning but I got it… then came a hit of fatigue.

He had read about this before. The dreaded bonk. Bonking was said to be the final drips of glycogen being removed from the muscle’s cells, with an accompanying burn suggesting rapid production of lactate. It also meant he had spent the last two hours less aerobic than he thought. Making it to mile twenty-two, Lance noticed his heart rate ten-beats over his planned pace. His breath was getting harsher, his legs getting weaker. The mile twenty-four marker went by and he was down to nearly a walk, lips dry and stomach lurching. The last half mile was a blur as Lance crossed the line his raised arms quickly fell, and so did he, right into a chair near the finish line.

Discuss the necessity of Lance’s training to prepare for his ability to fuel a marathon with specific reference to the major organ systems involved and their purpose. Identify the needed reactants and excreted products Lance utilized during his ongoing respiring, with specific reference to where each is created or used. Finally, predict the influence of his experimental goo and suggest advantages and disadvantages to its use, as well as better use with reference to time and impact on the ability to enter and circulate to where it would be needed

Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics. Coins found in excavations may have their production date written on them, or their may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

Answer: The products are spermatozoa that each have a head, midpiece and tail.

Explanation:

The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.

Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

Answer:

Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.

Explanation:

Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.

The major difference during cytokinesis in eukaryotes with or without a cell

wall is in the formation of cell plate in cells with cell wall while in animal

cells cytokinesis occurs through the formation of a cleavage furrow.

Cytokinesis is the process of cell division in which the cytoplasm divides

into two. Plants have cell walls while animals lack cell walls.

Animal and plant cells form cleavage furrow and cell plate respectively

which aids division into two equal parts.

Answer:

why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.

With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.

A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.

In most cases, the light is focused on the sample by passing it through a condenser.

After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.

The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.

Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.
