Answer: Tropical cyclones usually weaken when they hit land, because they are no longer being "fed" by the energy from the warm ocean waters. However, they often move far inland, dumping many inches of rain and causing lots of wind damage before they die out completely.

Answer:

A segment of DNA

Explanation:

Genes are parts of DNA

A gene is a segment of the DNA (deoxyribonucleic acid). DNA is the genetic material of the cell which contains the information for the development of different characteristics in an organism. Thus, the correct option is B.

A gene is the basic unit of heredity in an organism. It can also be defined as the molecular gene which is a sequence of nucleotides in the DNA molecule that is transcribed to produce a functional RNA which synthesizes a protein. There are two main types of molecular genes which include protein-coding genes and the noncoding genes.

Protein-coding genes or exons are the regions in the DNA which encodes for the synthesis of protein and the non-coding genes or introns are the segments of the DNA which does not code for any protein and thus are spliced in the post-transcriptional mechanism.

Therefore, the correct option is B.

1:As of recently, the essential contention for species de-termination was that it offered humankind an opportunity to make up for itself for the wrongs submitted north of millennia. People, one could really guarantee, have been messing up the planet since days of yore. Thus, a large number of the species that have been the objectives of de-termination endeavors have been picked on the grounds that they appear to have some essential thing right to make due. Frequently, they look similar as species that have made due until the present time. Assuming it hadn't been for people meddling with their normal natural surroundings and sensitive environments, the contention goes, they would have been prospering today.:2To get around this contention, however, a few researchers are beginning to put forth the defense that it wasn't Mother Nature who did in the wooly mammoth — it was people. When the planet began to defrost, people came into contact with the wooly mammoth in more prominent numbers, and started to chase them savagely after their meat, bones and even skin. It's basically the traveler pigeon proposal, stretched out to the wooly mammoth. De-eradication fans will most likely let you know that people bear a sort of transformative responsibility for having cleared out the wooly mammoth, quit worrying about environmental change.:3creating a highly-controlled environment (i.e. a theme park) where the wooly mammoth could conceivably flourish – it doesn’t reason that you can simply hit the “rewind” button on evolution. As some conservationists are already warning, bringing back a species like the wooly mammoth could lead to the disappearance of other species who share similar habitats. Once you bring back a new species, you have to start thinking about ecosystem effects — and about Butterfly Effects. Bringing back the wooly mammoth would require massive changes to existing ecosystems.:4Yet, that equivalent contention – an opportunity to reclaim human bad behaviors over an improper annihilation – doesn't hold on account of the wooly mammoth. The wooly mammoth, with its monstrous hair coat to save warmth, had no way for endurance once the Ice Age finished. As Darwin originally guessed, advancement resembles a calculation followed commonly. In the event that a variation assists an animal varieties with getting by and thrive, the transformation will stick. Assuming it doesn't, it will ultimately vanish from the genetic stock. For better or for more regrettable, certain species will go terminated when they can presently don't adjust to their current circumstance. It wasn't only that wooly mammoths had substantial hair coats – they had a wide range of different variations that assisted them with flourishing during the Ice Age, as enormous tusks to clean up snow and ice. Bringing back the wooly mammoth would be commensurate to bringing back an animal types that had the right to go terminated. : main idea Accepting totally effective cloning to make sound creatures, the cloned wooly mammoths would in all likelihood have hopeless existences and couldn't have ever evident freedomWhat's more not just the productive restoration of the wooly mammoth, but it's full rewilding into the Arctic." Bringing species like the wooly mammoth back into the frosty might perhaps help deferred down non-renewable energy source side-effects in the area and help with restoring lost organic frameworks, Lamm said.But think about how conceivable it is that they somehow made due. Our Arctic regions would look an incredible arrangement changed, and not because there would be huge assessed, shaggy animals meandering around. There would be less elk, moose, and caribou considering the way that the wooly mammoth would out battle them for food.Assuming absolutely viable cloning to make sound animals, the cloned wooly mammoths would probably have miserable presences and couldn't have ever clear freedomLamm said expecting the association is productive, research has shown bringing back ended species could reshape the Siberian tundra and in other Arctic regions to be more specialist of the normal game plan of the Arctic glades when it was an unrivaled carbon-sequestering areaLamm said assuming the organization is effective, research has shown bringing back wiped out species could reshape the Siberian tundra and in other Arctic districts to be more agent of the biological arrangement of the Arctic fields when it was a superior carbon-sequestering location.But imagine a scenario in which they some way or another made due. Our Arctic locales would look a ton changed, and not on the grounds that there would be enormous measured, shaggy creatures meandering around. There would be less elk, moose, and caribou in light of the fact that the wooly mammoth would out contend them for food.

Answer:

CARBOHYDRATE DIGESTION AND ABSORPTION

For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.

The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).

The major disaccharidases, located in the brush border of the intestinal lumen, are

•

Maltase—hydrolyzes maltose

•

Sucrase-isomaltase—hydrolyzes sucrose and isomaltose

•

Lactase—hydrolyzes lactose

Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.

HISTOLOGY

Brush Border Dynamics

The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.

Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.

The runner in question wishes to complete a two-hour run while expending 4kcal or calories per minute, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.

Since every gram of protein adds 4 calories of energy to the meal, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.

Answer: mRNA is transcribed from DNA and carries information needed for protein synthesis. During the translation phase of protein synthesis, the tRNA carry specific amino acids the the ribosome, and rRNA plays a role in the synthesis of the ribosome which is the site of translation phase of protein synthesis.

Explanation:

Answer:

The non-coding regions of DNA are called introns. They are significant in evolution since they offer a great 'recipe' for recombination with genes/exons. Therefore, this offers variations among individuals on which natural selection could act upon to help a population adapt to changes in the environment. Introns also offer an additional step in gene regulation through the splicing of introns in making of mRNA.

         We know more of the moon than we do of our own oceans! There are many, many, organisms on Earth that have not been classified. We have not been able to explore deep in the ocean, extremely cold climates, and some may have even been missed in "our backyard" because Earth is so diverse! According to National Geographic, "Even after centuries of effort, some 86 percent of Earth's species have yet to be fully described, according to new study that predicts our planet is home to 8.7 million species. ... So far, some 1.2 million species are known to science."

Explanation:

Weathering is the process by which rocks disintegrate into smaller fragments. Rock expands (with heat) and contracts (with cold) in response to temperature changes.

Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.

Rock responds to temperature fluctuations by expanding with heat and contracting with cold. This is frequently observed with a weathering process known as Frost wedging, in which water freezes and thaws inside rock fissures. Salt wedging is a different type of weathering in which the salt that is left over after water evaporates can exert pressure on rock fissures.

Thus, Weathering is defined as the process by which rocks disintegrate into smaller fragments.
