What are the two theories that are combined in the synthetic theory of evolution?
The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
Synthetic theory of Evolution The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.The theory explains that changes in the genes of organism are what causes the evolution of organism.
The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.
The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.
Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

Which of the following is a correct association?
Answer:
The first one
Explanation:
because it has the most words on their.
The correct association is option a.The cell synthesises proteins and organelles in the G2 phase (also known as the "Gap 2 phase") of the cell cycle in order to prepare for cell division.
The cell enters the G2 phase following DNA replication, which takes place during the S phase. In order to manufacture the elements required for cell division, the cell continues to expand and goes through further protein synthesis during this phase. These proteins play a role in the development of the mitotic spindle, control of cell cycle checkpoints, and cytoskeleton organisation.
The cell also creates organelles like the mitochondria and endoplasmic reticulum to make sure there will be enough energy and cellular building blocks for the impending division in the phase.

web site: The de-extinction of the woolly mammoth would be an evolutionary mistake
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.
describe why rocks found at the bottom of the river are smooth and flat.Please in your own words,My teacher would get mad
The rocks found at the bottom of a river smooth and flat because those are collides with each other.
Explanation:
At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.
This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.
Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.
What is Abrasion?Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.
This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.
Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

The role of DNA segment that do not code for proteins
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.

Which of the following statements regarding digestion and absorption of carbohydrates is TRUE? Lactose intolerance results from an insufficiency of the enzyme amylase. Digestible polysaccharides are broken down into the monosaccharides glucose, galactose, and fructose, which can be absorbed. Sucrose is the main form of carbohydrate that can be absorbed by active transport across the intestinal epithelium. Carbohydrate digestion begins in the stomach. Cellulose from plants is a polymer of glucose that can be easily digested and absorbed by the human GI tract.
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.
