The explanation for the kind of turtle found on the Galapagos islands with high vegetation: (C) Turtles possessing genes responsible for long necks had greater chances of survival and were able to attain their reproductive age.
Galapagos islands exhibit two distinct kinds of tortoises which vary in shape. The different shapes can be attributed to the distinct feeding habits that the tortoises have adapted according to the surrounding habitat.
The turtle inhabiting the islands with high vegetation possessed long necks as compared to the second type of turtle which feed largely on grasses and low-lying vegetation. Since the second type of turtle inhabited the region with low-lying vegetation, therefore, raising their heads in order to feed, was not essential to them.

the discomfort associated with irritable bowel syndrome can be alleviated with low doses of the class of antidepressants that block the reuptake of serotonin from the synaptic cleft (the space between adjacent neurons). serotonin is a relatively small polar neurotransmitter used to transmit nerve impulses in the nerve tissue in the gut and central nervous system. serotonin is transported back into the releasing neuron up its concentration gradient and down a sodium gradient. how might an antidepressant block serotonin reuptake by the releasing neuron?
It could block active transport of serotonin back into the cell by blocking a serotonin-sodium symporter.
The gastrointestinal system, usually known as the stomach and intestines, are affected by the illness known as irritable bowel syndrome (IBS). Constipation, diarrhea, and stomach discomfort are all possible symptoms. There may also be cramping.
IBS is a chronic ailment that requires long-term management. The abdominal discomfort of patients who took antidepressants for their IBS symptoms significantly improved, and other IBS symptoms including diarrhea, constipation, bloating, nausea, or urgency decreased as well.
Selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) may both lessen general IBS symptoms. Approximately 55% of patients on TCAs or SSRIs will benefit, as opposed to 35% of patients taking a placebo.

Water-soluble vitamins are quickly absorbed by the body, so you won't need to store a lot of them to help maintain your body's nutritional needs balanced naturally. In contrast, fat-soluble vitamins are considerably different. The body has access to these vitamins because they are stored in tissue and dissolve in fat. Although fat-soluble vitamins can also be toxic, water-soluble vitamins are more likely to do so since they are promptly excreted from the body and have a larger potential for toxicity. Fat-soluble vitamins can also be retained in tissues. Consult your doctor first before taking any vitamins or minerals.

The 23 pairs of chromosomes in cell nuclei plus a tiny DNA molecule present in each mitochondria make up the human genome, which is a full set of nucleic acid sequences for humans.The nuclear genome and the mitochondrial genome are often treated separately.
Why is the human genome important? What is it?
The 20,000–25,000 genes that make up the human body are all encoded in the coding portions of DNA, which also make up the noncoding regions of DNA. Together, these two types of DNA make up the human genome.The whole human genome's DNA sequence was known by 2003. A few viruses have RNA (ribonucleic acid) genomes, but the majority of genomes, including those of humans and all other cellular life forms, are formed of DNA (deoxyribonucleic acid).The chains of monomeric subunits known as nucleotides make up the polymeric molecules known as DNA and RNA. the CDC's list of the top causes of death).The genetic makeup of every human being is 99.9% same.Differences in the 0.1 percent that is left can reveal crucial information about the origins of diseases. Nearly every one of the trillions of cells that make up our body, including immune cells that help protect us from constant external attack and neurons that carry impulses throughout the brain, have the same 3 billion DNA base pairs that make up the human genome, which is our whole genetic code. As we discovered in the above example, there are three genome types that exist since the mutation is A–G: AA, AG, and GG.The GG type of these three genome types has the most anti-alcohol activity, whereas the AA type has the least activity and can barely digest alcohol.

trematol is a metabolic poison derived from the white snake root. cows eating this plant concentrate the poison in their milk. the poison inhibits liver enzymes that convert lactic acid to other compounds for metabolism. why does physical exertion increase symptoms of poisoning by trematol? why does the ph of the blood decrease in a person who has digested trematol?
Here are the answers to the questions respectively:
Physical exertion increase symptoms of poisoning by trematol because the generation of lactic acid through fermentation, and when liver enzymes are inhibited, the accumulation of lactic acid lowers blood pH.The pH of the blood decrease in a person who has digested trematol because exercise stimulates metabolism, and blood pH rises as a result of the electron transport chain pushing H+ out of the mitochondria.A metabolic poison called trematol is made from the white snake root. The toxin is concentrated in the milk of cows that consume this plant. The toxin prevents the liver's enzymes from metabolizing lactic acid into other chemicals.
Our cells make lactic acid through a process known as fermentation when there is not enough oxygen present. Particularly in our muscles, the pyruvate from glycolysis is converted to lactic acid to replenish NAD+ from NADH, allowing glycolysis to continue producing ATP.

In muscles, the source of ATP depends on the duration of exercise.
The duration of exercise is an important factor in determining the source from which ATP is derived in the muscles.
Initially, when there is enough supply of oxygen, the body will use the method of aerobic respiration for the production of ATP. By the aerobic method, carbohydrates, fats and proteins derived from the food can be used as an energy source.
When the time duration increases, the muscles will switch to anaerobic respiration as there will not be a shortage of oxygen. In this case, energy will be derived from glucose that we get from the breakdown of glycogen. Glycogen is the form in which energy is stored in the body.
