Laparoscopic Cholecystectomy

Gallbladder is known to be pear shaped organ that is found beneath the right side of the liver.  It functions by collecting and concentrating the bile (digestive liquid ) produced by the liver. However, Laparoscopic Cholecystectomy (Laparoscopic Gallbladder Removal ) is known to be a surgical procedure performed for the removal of gallbladder which involves the use of small incision instead of large one.

The main term for the removal of gallbladder calculi by means of an open procedure is cholecystectomy.

The main term for the removal of gallbladder calculi by means of an open procedure is cholecystectomy. This surgical procedure involves the complete removal of the gallbladder to treat conditions such as gallstones. This may be done due to gallstones, inflammation, or other gallbladder-related issues. Often performed laparoscopically, the surgeon makes small incisions and uses a camera for visualization.

Cholecystectomy is a common and generally safe procedure, and the body can adapt to the absence of the gallbladder. While patients may experience changes in digestion, the procedure aims to alleviate symptoms and prevent complications associated with gallbladder disorders.

Connective tissue disease include some diseases where tissues rich in protein, that support body parts and organs get damaged. These tissues include cartilage, bones and fats and the diseases caused by the damage of these tissues include joints pain, muscles damage and skin damage etc.

However, the problems from Connective tissue disease are not solely confined to these organs and can effect other organs too like kidneys,lungs,heart,eyes,blood vessels and gastrointestinal tract. More than two hundred connective tissue disorders exist that show a variety of effects, Here we will discuss only few:

Epidermolysis bullosa:

This connective tissue disorder effect the skin by making it very fragile that even a minor cut can tear the skin and leave blisters. This occurs due to defect of some proteins.

Marfan syndrome:

This syndrome affects ligaments, heart, eyes, and blood vessels. The people suffering from the disease have very long bones and abnormal placement of eye lenses. This is caused by genetic mutations.

Osteogenesis imperfecta:

This conditions makes the bones very brittle and lowers the mass of joints, muscles and ligaments. It can also cause Curved spine,Thin skin  and breathing problems in the person suffering from the disorder.

This also occurs due to mutation of genes.

Polymyositis and dermatomyositis:

In both these disorders, inflammation of skin and muscles occur and can cause symptoms fatigue, weakness, Shortness of breath,Difficulty swallowing ,Weight loss .

Answer:

The given statement is false.

Explanation:

The Precambrian era contains all of the time before 600 million years ago. The earth's history before the formation of the oldest rock with observable fossils in them refers to Precambrian era.

The discovery of sediments and other evidence implies the surface temperature of above 0° C during the early part of the Precambrian era.

Traces of hundreds of life forms are found in the microfossils of the Precambrian era. Some of these species were early photosynthesizers. Stromatolites are stratiform structures made from microorganisms, particularly blue-green algae.

So, the statement is false.

Mitosis refers to a procedure of producing more cells, which are genetically similar to the parent cell. It plays an essential role in the development of embryos, and it is essential for the development and growth of the bodies as well. Mitosis generates novel cells and substitutes the cells, which are lost, old or destructed.  

In mitosis, a cell differentiates to produce two similar daughter cells. It is essential that the daughter cells exhibit a copy of each chromosome, so the procedure includes copying the chromosomes initially and then carefully distinguishing the copies to provide each new cell a complete set.  

The question is assuming that the coyotes are the only predators (hence eliminating all predators of the rabbit).

What would happen is that the rabbit population would continue to thrive throughout the years, until the producers cannot support the rabbits, leading to a mass extinction of the rabbits and the destruction of the ecosystem that used to be there.

Answer:

The high nutrient enriched soil, long growing period and sufficient sunlight exposure are major factors which makes the marshes more productive than the bogs.

Explanation:

Marshes are one of the highly productive ecosystems just like the swamps.  This is because of the following reasons –  

a) High nutrient depositions due to the flow of nutrient enriched sediments of river though the marsh area

b) They have long growing period  

c) Sufficient amount of sunlight exposure.  

While bogs remain water choked most of time in a year and thus decaying plants and leaves form an important part of its soil. Such soils have low oxygen and nutrient content.  

The phenomenon called incomplete metamorphosis is seen in grasshopper.

The total number of the stages act as major difference between incomplete and complete metamorphosis. The former has 3 stages namely egg, nymph and adult, whereas the latter has 4 stages namely egg, larva, pupa and adult.

The process of incomplete metamorphosis is seen in insects such as grasshopper, termites, true bugs, praying mantis etc. The caterpillar shows complete metamorphosis at the end of which adult butterfly emerges out.  

In incomplete metamorphosis, initially, the insect comes out of egg. Then it grows and becomes nymph which is a smaller version of adult insect, its physical appearance is very vulnerable due to its young age. Then it grows into a adult insects and lives till its end.

Cellular respiration depends on two chemical reactants; glucose and oxygen.  Glucose and oxygen are made available to plants and animals for cellular respiration thanks to photosynthesis.  Photosynthesis is the chemical reaction that uses solar energy to convert water and carbon dioxide into glucose and oxygen.  Without photosynthesis, the available glucose and oxygen on the planet would quickly deplete to the point that life could not be sustained on Earth.

Photosynthesis produces glucose and oxygen, which are required for cellular respiration. Therefore, without photosynthesis, cellular respiration in plants and other organisms could not occur.

The dependency of cellular respiration on photosynthesis in plants and other organisms is explained by the fact that photosynthesis produces the essential materials required for cellular respiration. Specifically, photosynthesis produces glucose and oxygen, which all organisms use to perform cellular respiration. Photosynthesis forms an energy link with cellular respiration.

In the process of photosynthesis, plants convert light energy into chemical energy, creating glucose and releasing oxygen into the atmosphere. This glucose and oxygen then become the fuel for cellular respiration, a process where energy is released from glucose and used to create ATP, a molecule that powers cellular activities.

Therefore, without the glucose and oxygen produced by photosynthesis, cellular respiration could not occur. This signifies the intricate relationship and dependency between photosynthesis and cellular respiration, highlighting the vital role they play in maintaining life on Earth.

Answer:

During the process of cellular respiration,that comprises three further processes (glycolysis, Kreb cycle and electron transport chain) the energy present in glucose molecules is transformed into ATP.

Explanation;

Cellular respiration is a process in which sugar breaks down to produce H2O and carbon di oxide, and during the same process energy in the form of ATP packets is formed that can be later on used by an organism to perform day to day activities.

Cellular respiration is the process during which energy present in the bonds of glucose are transformed into the form of ATP. ATP is the molecule that stores energy in its phosphate (PO4) bonds.

Hydrolysis of one phosphate bond of ATP releases almost 7.3 kJ of energy. Similarly, the hydrolysis of second phosphate bond of Adenosine mono phosphate releases around 3.4 to 3.6 kJ of energy. Therefore, the total amount of energy released from ATP hydrolyses is around  18 to 18.2 kJ of energy!  

This energy is all that living organisms need to fulfill their cellular and physical work requirements.

Hope it help!

Answer:

Cellular respiration refers to the set of metabolic reactions taking place in a cell in order to harness energy from the food (glucose) and convert it to more usable form which is ATP (adenosine triphosphate).

The bonds of glucose and oxygen are broken, added, and are rearranged to form carbon dioxide, water and ATP.

The glucose is oxidized through various steps such as glycolysis, pyruvate decarboxylation, and Krebs cycle.

All the NADH₂ and FADH₂ formed by the above reactions undergo electron transport chain which causes oxidative phosphorylation of ADP to form ATP.

The summary of cellular respiration is shown in the form of the chart below.

A man with Type A blood marries a woman with Type AB blood. According to predicted outcomes based on genetics, their children may have all blood types EXCEPT Type O, which is in option D.

The ABO blood group system is determined by the presence or absence of two types of antigens (A and B) on the surface of red blood cells and the presence or absence of antibodies against these antigens in the plasma. A person with type A blood has the A antigen on their red blood cells and produces antibodies against the B antigen in their plasma. A person with type AB blood has both A and B antigens on their red blood cells and produces no antibodies against either A or B antigens in their plasma. Therefore, if a man with type A blood (genotype AA or AO) marries a woman with type AB blood (genotype AB), their possible offspring could inherit either the A or B allele from the father and the A and B alleles from the mother, resulting in either blood types A, B, or AB.

Hence, a man with Type A blood marries a woman with Type AB blood. According to predicted outcomes based on genetics, their children may have all blood types EXCEPT Type O, which is in option D.

Explanation:

The correct answer is option 2, that is, combinations.

The production of offspring with combinations of traits, which vary from those found in either of the parents is known as genetic reshuffling or genetic recombination. The genetic recombination, in eukaryotes, can result in the generation of a new set of genetic information, which can be conducted on from the parents to the offspring. Due to these variations, it is unlikely that any two individuals will be similar.  

The Earth is 4,54 billion years old. This age has been determined with the radioactive dating technique. The precise decay rate of radioactive elements is used as a clock: the number of daughter products in one rock indicates its age.

The oldest meteorites ever dated in the Solar System are 4,56 billion years old, the oldest minerals on Earth are 4,4 billion years old, and the oldest rocks on Earth are 4 billion years old. These ages are very consistent because the meteorites had to form before the accretion of our planet, and the Earth had to cool down before the first minerals could crystallise.

The Solar System was formed around 4.6 billion years ago, out of the collapse of a dense cloud composed of dusts and gases. Meteorites, which are the very components of our planets (through the process of accretion), are the remnants of the Solar System’s origins. Dating meteorites thus allows us to give a lower age to the Solar System (4,56 billion years old).
