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.

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.

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.

Explanation:

For the most part the birds will be negatively affected by the early spring, they won't have the food they need and because they missed finding ideal nesting spot one of two things will happen, they will either pick an unsafe nesting area which can result in their young being hurt or even themselves, and/or they won't breed at all and because of this the Warbler population will decrease due to low mating rates. Eventually, the birds will evolve in a way and start coming back from their migration earlier than previous generations and thus they will have access to the food and nesting areas that they need and the population will spike again.

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.  

Answer:

C. Convergent evolution.

Explanation:

Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.

Answer:

Option C, The relative dating was done incorrectly.

Explanation:

As it is mentioned here in the description that scientist know that the actual age of rocks must be 2.5 billion years and this age of the rock must have been derived through some methodology of radioactive dating. Now since the potassium-argon method was used three times and it depicted the same result every time stating that the age of rocks is 1.3 billion years. Therefore there are high chances that earlier method used that estimated the age of rock as 2.5 billion years must be wrong.

The energy role of a grizzly bear is that of a consumer because it cannot make its own food.

Grizzly bears are considered heterotrophs as they derive their energy from consuming other organisms, both plants and animals. They depend on the environment for food, and not on photosynthesis. A distinct energy-related physiological process observed in grizzlies is hibernation during which they depend on stored fat for energy.

The energy role of a grizzly bear is that of a heterotroph because it cannot make its own food. In biology, animals that cannot produce their own food are termed as heterotrophs. They derive their energy from external food sources. Grizzly bears, as an example, are omnivores and consume both plants and animals for sustenance. Thus, they depend on the environment to provide them with nourishment rather than photosynthesizing, similar to plants or certain microbial organisms.

Another important life cycle aspect of grizzly bears related to their energy consumption is hibernation. Before winters, they enter a phase of hibernation during which they rely on their stored fat reserves for energy. This process is not just random; there are certain environmental cues that trigger this physiological change in grizzly bears. Hibernation allows them to survive through winters when food resources are scarce.

Bears that encounter humans for food sources are more inclined to intrude human habitations, indicating an adaptive behavior in search of energy (food) sources.

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).

The labels that should be used to complete the diagram are:

X: Enzymes

Y: Gene for sweeter fruit

This represents the process of genetic modification, where enzymes are used to insert a specific gene (for sweeter fruit) into the DNA of an apple tree.

Enzymes are biological molecules that catalyze chemical reactions, and in this process, enzymes are involved in modifying the apple tree DNA to produce sweeter fruits. The specific gene responsible for the desired trait of sweeter fruit is denoted as Y.

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.  

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.
