why is there infinite variety in the living world ?

Answers

Answer 1

Infinite variety in the living world, known as biological diversity, is a result of evolutionary processes and mutations that allow organisms to adapt to different environments. These adaptations lead to a range of species that can survive under various conditions, thus contributing to the vast diversity of life on Earth.

The question 'why is there infinite variety in the living world?' touches on the concept of biological diversity, which refers to the multitude of different species of plants, animals, and microorganisms that exist on Earth, as well as the complexity of ecosystems they form. There are over a million known species, and scientists estimate that this is just a fraction of the total number that exists. The vast variety of life is attributed to evolution and the concept of mutation, where random changes in genetic material create new traits that can be advantageous for survival. Organisms that are better suited to their environment tend to have greater reproductive success, as per the principles of natural selection. Over time, as environments change, the process of natural selection favors the survival of organisms that have beneficial mutations, leading to a rich diversity of species adapted to a wide range of environments.

Environmental changes can be both gradual and sudden, such as natural disasters, which also play a role in shaping the diversity of life. Species diversity ensures that at least some life forms can survive and thrive amidst various environmental shifts. The biodiversity we observe today is a snapshot of a dynamic, ongoing process of species adaptation and evolution.

What is the difference between a polynucleotide chain and a polypeptide chain

Answers

A polypeptide chain is a sequence of amino acids covalently linked by peptide bonds. A short polypeptide consisting of 50 or fewer amino acids is termed a peptide. A polynucleotide chain is a sequence of nucleotides covalently linked by ribose (or deoxyribose)-phosphodiester bonds, e.g. either DNA or RNA.
Polypeptide (protein) chains are linear, with rare exceptions where a side-chain forms an isopeptide bond. Polypeptide chains may be covalently linked together, most commonly by disulfide bonds.
Final answer:

A polynucleotide chain is a sequence of nucleotides that forms the basis of DNA and RNA, while a polypeptide chain is a sequence of amino acids that subsequently fold into complex structures to form proteins with various shapes and functions.

Explanation:

A polynucleotide chain and a polypeptide chain are both crucial components of biological molecules, yet they differ significantly in their makeup and function. The polynucleotide chain is composed of a series of nucleotides, which include a phosphate backbone and nitrogenous bases such as purines and pyrimidines. This structure forms the basis for DNA and RNA. Some nucleotides combine in a 5'-3' phosphodiester bond, creating a polynucleotide with a free 5' phosphate at one end and a free 3'-OH at the other.

On the other hand, a polypeptide chain consists of a sequence of amino acids connected by peptide bonds. This sequence, referred to as the primary structure, then forms further complex structures like alpha-helices and beta-pleated sheets, which result in unique shapes and functions of proteins. An example is the insulin hormone with two distinct polypeptide chains, A and B. Changes in the primary structure can result in alterations in the protein's structure and function, as seen in sickle cell anemia.

The energy transformation  depicted here is electrical energy ⇒ light energy. The remaining 350 J of energy was transformed into 350 J of heat energy.

What is energy transformation?

Energy transformation is defined as the transformation of energy from one form to another. In molecular biology, the concept of transformation has been extensively exploited. Transformed bacteria can be employed as host cells to create multiple copies of the DNA because they are simple to grow in huge numbers.

Efficiency can be shown as an output-to-input ratio. Output, often called work output, is the entire quantity of productive work completed, excluding waste and spoilage. In order to convert efficiency to a percentage, divide the ratio by 100. Energy cannot be created or destroyed, according to the rule of conservation of energy. It can only switch between different energy states.

Thus, the energy transformation  depicted here is electrical energy ⇒ light energy. The remaining 350 J of energy was transformed into 350 J of heat energy.

how would you describe the relationship between potential energy and kinetic energy? Why does this relationship occur?

Answers

Answer:

Potential energy can be described as the energy possessed by an object by virtue of its position. It can be described as the energy possessed by an object which is at rest.

Kinetic energy can be described as the energy possessed by an object by virtue of its state of movement. In simpler words, it is the energy possessed by a moving object.

The potential energy in an object is converted into kinetic energy when any work has to be done by the object. This relationship occurs because one form of energy can be converted into another form of energy.

Answer:

The total energy of the skater is the sum of his potential energy and kinetic energy. As potential energy decreases, kinetic energy increases, and vice versa. This occurs because kinetic energy is the energy of motion and potential energy is stored energy.

I and II only

I and III only

Answer:

I and III only

Explanation:

The term cell breath alludes extensively to the creation of ATP through the synthetic breakdown of glucose into carbon dioxide and water. Be that as it may, this procedure has a few segments. Your body utilizes cell breath to change over glucose to ATP and carbon dioxide utilizing oxygen. Glucose travels through three phases in cell breath, glycolysis where glucose is changed over to pyruvate, and two ATP and NADH are made.

The main part of the procedure is performed anaerobically (without oxygen) in the cytoplasm when glucose atoms are changed over to particles of pyruvic corrosive, and ATP is delivered. Pyruvic corrosive atoms at that point proceed to the citrus extract cycle where they are separated into carbon dioxide and electrons, and more ATP is delivered. Cell breath happens in both eukaryotic and prokaryotic cells, with most responses occurring in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes.

Fermentation is a separate process from cellular respiration and is therefore an incorrect answer.

D): Energy is absorbed more than radiated near the equator.
E): Energy is carried from the equator to poles in surface currents.
F): Energy is carried from the equator to poles in deep ocean currents.

Answers

Answer:

1. energy is absorbed more than radiated near the equator

2. energy is carried from the equator to poles in surface currents

3. energy is radiated more than absorbed near the poles

Explanation:

Final answer:

Thermal energy in the oceans is absorbed more than radiated near the equator, radiated more than absorbed near the poles, and is carried from the equator towards the poles through surface currents.

Explanation:

The transfer of thermal energy in the oceans is a complex process influenced by various factors such as sunlight intensity, ocean currents, and latitude.

The correct answers to the question are:

B: Energy is radiated more than absorbed near the poles.D: Energy is absorbed more than radiated near the equator.E: Energy is carried from the equator to poles in surface currents.

Near the polar regions, the angle of the sunlight is more oblique, reducing the amount of solar energy absorbed. Hence, these regions radiate more energy back into space than they absorb, maintaining their colder temperatures. On the other hand, at the equator, the sunlight hits the Earth's surface more directly, allowing for greater absorption of energy, which is why it is usually warmer. Additionally, ocean surface currents play a significant role in transferring energy from warmer equatorial waters to the cooler polar regions.

Answers

As we travel from plankton to polar bear, only about ten percent of the energy in one trophic level gets passed to the next level.

Explanation:

The energy flow in an Ecosystem has to aspects which should be considered:

Firstly, the energy flows is unidirectional from producers through herbivores to carnivores.Secondly the energy flow decreases with successive trophic levels.This is due to the fact that some energy is always lost as heat and is used by the organism at that trophic level.

Lindeman's work suggested that about 90% energy is used up at the trophic level and only ten percent of it is transferred to the next level.

This was later formulated as the Ten percent law.

Final answer:

Only about 10% of the energy is transferred from one trophic level to the next in an arctic marine food chain, due to energy lost as heat, which limits the number of trophic levels that can be supported.

Explanation:

Consider this simple arctic marine food chain: plankton → Arctic cod and Arctic char → seals → polar bear. As we travel from plankton to polar bear, only about 10% of the energy in one trophic level gets passed to the next level. This is due to the loss of energy as heat between trophic levels in accordance with the second law of thermodynamics. It is significant to note that, after four to six trophic energy transfers, the amount of energy remaining may not be sufficient to support viable populations at a higher trophic level.

The incident of Volcanic eruption will result in Primary Succession instead of Secondary Succession. The correct option is B.

What is primary succession?

When a new piece of land is produced or is first exposed, primary succession occurs.

This may occur, for instance, when lava solidifies and forms new rocks or when a glacier recedes and reveals bare rocks. In the initial succession, organisms have to start over.

In primary succession, living organisms first occupy newly exposed or newly created rock.

In secondary succession, a previously inhabited area is disrupted, then recolonized as a result of the disturbance.

The likelihood of primary succession is highest when a lava flow has wiped out all life in a natural community.

a polypeptide contains 103 amino acids, what is the length of the base pairs?

Answers

Answer:

309 (+3 for stop codon)

Explanation:

The Genetic code is a scheme of 3 nucleotide base pair codons that code for different amino acids.Each amino acid has a codon of 3 base pairs. Therefore, to calculate the size of the mRNA, we use the formula:Total base pairs = Amino acids * 3B.P = 103* 3 = 309The length of the mRNA that codes for 103 amino acids is 309 base pairs plus a 3 base pair stop codon that terminates translation.

     

To calculate the length of base pairs for a polypeptide with 103 amino acids, one multiplies the number of amino acids by three as each is encoded by a codon of three nucleotides, resulting in 309 base pairs.

If a polypeptide contains 103 amino acids, determining the length of base pairs in the corresponding DNA sequence involves understanding the genetic code. Each amino acid in a polypeptide is coded by three nucleotides, known collectively as a codon. Therefore, for a polypeptide of 103 amino acids, we would expect 103 codons. Since each codon is composed of 3 nucleotide pairs, the length of base pairs would be 3 times the number of amino acids, giving us a total of 309 nucleotide pairs.

The second statement is the correct one: The weight of the chicken would increase, but there would be no change in mass. The mass of an object, in this case a chicken, is a measure of the amount of matter it contains and stays constant regardless of its location. However, weight is a measure of the force exerted on the object's mass due to gravity. Because Jupiter is a larger planet with a stronger gravitational pull than Earth, the weight of the chicken would increase on Jupiter compared to Earth while its mass remains the same.

Drugs affect the nervous system by acting as agonists to enhance neurotransmitter activity, as antagonists to decrease it, by mimicking or interfering with the natural neurotransmitters' effects, and by affecting the sympathetic or parasympathetic systems.

Explanation:

Drugs can influence the nervous system in various ways, generally by impacting the transmission of nerve impulses within the brain. Here are four ways that drugs can affect the nervous system:

Agonist Effects: Drugs can act as agonists, enhancing the activity of certain neurotransmitters. For example, stimulants like amphetamines increase dopamine activity, leading to elevated mood and alertness.Antagonist Effects: Some drugs act as antagonists, decreasing neurotransmitter activity. Antagonists can help to balance neurotransmitter levels in conditions where there is an excess of certain neurotransmitters.Sympathomimetic and Sympatholytic Effects: Drugs like sympathomimetics increase the sympathetic system response, potentially causing heightened alertness and energy. In contrast, sympatholytics dampen this response.Mimicry of Endogenous Substances: Certain drugs imitate natural neurotransmitters in the body, tricking the brain and causing it to respond as it would to the neurotransmitter. Opiates are an example, as they mimic endogenous opioids, reducing pain perception.

Tiny organisms made of a single cell are called unicellular organisms, and include bacteria, plankton, and yeasts. These microscopic organisms perform all necessary life functions within one cell, which can be vastly complex for its size. Unicellular organisms are crucial to understanding the simplest forms of life in biology.

Tiny organisms that are made of a single cell are often referred to as unicellular organisms. These microscopic organisms can only be seen with the help of a microscope and encompass a variety of life forms, including bacteria, plankton, and yeasts. Unicellular organisms are a fundamental part of biology because they are living examples of the simplest form of life, being composed of a single cell that carries out all necessary functions for life.

Contrasting with unicellular organisms are multicellular organisms, which consist of many cells that combine to form tissues and organs, each specialized for different functions. On a simpler level, colonial composition refers to organisms that have multiple cells but no defined tissues or organs. Both mushrooms and yeasts can exist as single-celled organisms, highlighting the diversity within unicellular life forms.

In unicellular organisms, the single cell is the smallest structural and functional unit of the organism. This single cell must perform all functions that support life, differing vastly in complexity compared to multicellular counterparts. Some unicellular organisms, like Paramecium, are eukaryotes, meaning they have a membrane-bound nucleus and organelles within the cell.

Answers

Final answer:

The population that will likely show the largest increase as a result of almost all of the mice being consumed is insects.

Explanation:

The population that will likely show the largest increase as a result of almost all of the mice being consumed by a large group of cats is (1) insects.

When the mice population decreases due to predation, the insect population may increase because there will be fewer mice feeding on the insects and competing for resources. This may lead to a larger availability of food and less competition for the insects, allowing their population to grow.

Additionally, the decrease in the mice population may also indirectly benefit other populations such as foxes and hawks, as they rely on mice as a food source. With fewer mice, these predators may turn to insects as an alternative food source, further contributing to the increase in the insect population.
