What is structurally different between starch and cellulose that gives them different physical properties?.
Answers
Although Cellulose are macromolecules belonging to the same group of carbohydrates, but cellulose is a polysaccharide that has beta 1,4 linkages between glucose monomers while the starch is a polysaccharide that has alpha 1,4 linkages between glucose monomers.
What is Cellulose?Cellulose is the polymeric chains of glucose monomers linked together by beta 1,4 glycoside linkages, t is the most abundant organic molecule which is a structural unit of plants.
Cotton and paper are the examples of cellulose containing product which comprises about 4000-8000 glucose molecules with beta bonds between the 1st C of the first unit and the 4th carbon of the next glucose unit.
There two forms of cellulose like hemicellulose and lignin, cellulases is the enzyme which can hydrolyze the cellulose into its monomers; cellobiose is another form of cellulose which is formed from the hydrolysis of cellulose.

Answers
Answer:
Harvesting is the operation of gathering the useful part or parts of the plant and is carried out at the time when all the nutrients have developed and the edible parts have reached the appropriate degree of maturity.
Threshing or shelling consists of separating the grains, or the shells in the case of groundnuts, from the portion of the plant that holds them.
WINNOWING, the process of separating quality grains from chaff, is a crucial process in the cultivation of paddy. The traditional way of winnowing is making the dried grains fall from a height using shovels and a sieve.

A plate moves south at a rate of 2 cm/year. How many meters south from its original location will the plate be in 4,000 years? 8,000 meters south 4,000 meters south 200 meters south 80 meters southWhich source of evidence did Wegener use to support his theory of continental drift? fossils magnetic fields satellite mapping warm equatorial climates
Answers
Answer:
1. 8000 meters
2. Fossils
Explanation:
1. Rate of southern movement of the plate = 2 cm/year.
In 4000 years, the plate will move a distance of 4000 years * 2 cm/year = 8000 meters
Therefore, the plate will move a distance of 8000 meters south in 4000 years.
2. Wegener in supporting his theory of continental drift used fossils, geologic and glacial evidences. He compared the fossils found in different continents and argued that the presence of fossils of certain animal fossils such as the Lystrosaurus which are found in antarctica, India and South Africa indicates that the continents drifted apart as the Lystrosaurus could not have swam across the ocean to get to these different continents. Also, using geologic evidence by comparing rock structures on opposite sides of the Atlantic ocean, he determined that there were similarities between the rock strata of the Karroo system of South africa with the Santa Carina system in Brazil.
detection and characterization of leptospira infection and exposure in rats on the caribbean island of saint kitts
Answers
Leptospirosis is a widespread zoonotic and potentially life-threatening disease in humans and animals.
Numerous animal species keep Leptospira, the bacterium that causes this sickness, in their kidneys and excrete it in their urine. These creatures are a source of pollution for the environment and illness. Rats are an important reservoir host of the disease and have previously been reported to have Leptospira infection in the Caribbean island of Saint Kitts. However, there is presently no information on rats. The major objective of this study was to use a complementary set of diagnostic methods to identify Leptospira infection and exposure in two kinds of rats on Saint Kitts. Then, using a mix of serologic, molecular, and genomic methods, infecting Leptospira strains were described.

Answers
Answer:
Please find the difference below and their respective examples
Explanation:
Previously existing organisms leave behind evidences of their existence in form of remains that has been collected and mineralized called FOSSILS. However, the fossils of an organism (plant or animal) can either be a trace fossil or an original remain/body fossil. The difference between the two are as follows:
- An original remain is the fossilized body or body part of an organism that once existed. For example, bones, shells and fossilized leaf are examples of original remains.
- On the other hand, trace fossils refers to any form of evidence, apart from the organism's body, that suggests the presence of that organism in that particular place at a particular time. Trace fossils are said to be illustrate presence of life but indirectly (via their activities). Examples of trace fossils are burrows, tracks, marks etc.

reversing the new oral anticoagulants with prothrombin complex concentrates (pccs): what is the evidence?
Answers
Newer oral anticoagulants offer quite a few benefits over usual dealers (e.g. warfarin), however, they are nonetheless related to bleeding risk and currently, there is no validated reversal remedy for them. While there is a little guide for the use of sparkling frozen plasma, and restrained information handy on the outcomes of activated recombinant factor VII, preclinical statistics advocate that prothrombin complicated concentrates (PCCs) can also have possible in this setting. PCCs are presently used to successfully reverse warfarin-induced anticoagulation; however, scientific proof for their use with new oral anticoagulants is lacking, with most of the accessible records coming from preclinical animal studies. Furthermore, there appears to be variation in the capability of different PCCs to reverse the coagulopathy brought about by way of the new anticoagulants, and a lack of correlation between the reversal of laboratory check consequences and the reversal of anticoagulant-induced bleeding. Although there have been encouraging results, care must be taken in generalizing findings from animal fashions and nonbleeding human subjects to the state of affairs in bleeding patients. Ultimately, more evidence supporting anticoagulation reversal for new anticoagulants is needed, specifically related to the remedy of bleeding in human patients in a scientific setting. According to the present-day evidence, the use of PCCs can also be considered a sensible strategy in dire scientific situations; however, a consensus has not yet been reached concerning PCC use or dosing, due to lack of scientific data.

Most cells are infinitesimal, and can only be seen under a microscope. In the preceding sentence, what does infinitesimal mean?.
Answers
Here, the word infinitesimal means tiny. Most cells can only be visualized under a microscope since they are so tiny.
In general, all cells must be tiny. While not all cells have a sphere-like form, the majority do. A cell's surface area grows as the square of its radius as the radius rises, yet its volume grows as the cube of its radius (much more rapidly).Thus, a cell's surface area to volume ratio drops as it grows in size. If the cell were in the form of a cube, the same reasoning would hold true (below). The plasma membrane won't have enough surface area if the cell enlarges too much to support the rate of diffusion needed to accommodate the larger volume. In other words, a cell gets less effective as it develops. One technique to increase efficiency is to divide, while another is to create organelles with specific functions. These modifications result in the emergence of eukaryotic cells, which are more complex cells.Hence, the correct answer is tiny.

The volume of blood flowing through the skeletal muscles increases greatly during exercise. Give two ways in which the body brings about this increase.
Answers
Increase in blood flow to skeletal muscles:
1. Arterial blood pressure changes little during exercise. During exercise, metabolic demands on skeletal muscle increase dramatically. This causes the blood vessels that supply the muscles to dilate, increasing blood flow to the skeletal muscles.
2. The sympathetic nervous system plays an important role in regulating arterial blood pressure and blood flow during exercise, and several key neural mechanisms are involved in altering sympathetic vasomotor outflow.
How does the sympathetic nervous system affect blood flow?
In blood vessels, sympathetic activation narrows arteries and arterioles (resistance vessels), increasing vascular resistance and decreasing distal blood flow. When this occurs throughout the body, vascular resistance increases and arterial pressure rises.
How does the nervous system control blood flow?
Neurological regulation of blood pressure and blood flow depends on cardiovascular centers located in the medulla oblongata. This group of neurons responds to changes in blood pressure, blood oxygen levels, carbon dioxide, and other factors such as pH.
