The properties which have a single ownership or the one for which a particular individual or family is liable is called a private property. These are not accessible by everyone in the society except by the permission of the owner.

The properties that belong to the government and each and every person in the society have equal rights over it is called a public or common property. Usually these services or places can be accessed by every person .

Among the given examples,  A backyard, a farm yard and a private pond are examples of  private property But a city park can be visited by anyone in the society so it is an example of common.

Answer:

309 (+3 for stop codon)

Explanation:

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.

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:

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.

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.

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.

When a psychologist proposes an experiment that could cause disagreement in the study subjects - through a hoax - to measure their self-esteem, the Institutional Review Board Ethics Committee will say that deception is allowable only if it is revealed afterward and if the emotional distress that it causes is short lived.

Explanation:

Options for this question:

A. Deception is allowable only if it is revealed afterward and if the emotional distress that it causes is short lived.

B. Deception is allowable only if participants give informed consent prior to the experiment.

C. Deception is never allowable.

D. Deception such as this would cause emotional discomfort, so it should not be done.

Any study or research test applied to people is subject to the regulations of an ethics committee, who will set the guidelines for this study.

Research that aims to expose research individuals to negative feedback can have psychological and emotional repercussions that must be measured and controlled.

In this case, the opinion of the institutional ethics committee will be to evaluate the scope that this research can have and to suggest that those evaluated know, after the test, that it was only a test to measure their self-esteem and emotional response.

The institutional ethics committees are in charge of monitoring and guaranteeing the physical and emotional well-being of people -submitted to research tests or medical care- in addition to ensuring treatment with respect to their dignity.

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.

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.

Answer:

Fertilization is the union of an egg and sperm cell, process that occurs in sexual reproduction.

Explanation:

Fertilization or fecundation is a biological process that occurs in the context of sexual reproduction of living beings. It consists of the union of gametes, male (sperm) and female (egg), provided by the parents.

As a result of fertilization, the zygote is produced, a cell that will suffer successive divisions to form the embryo, the beginning of a new individual.

Both reproduction and fertilization are necessary processes for the perpetuation of a species.

During cellular respiration, cells obtain energy for performing work when...

I. energy-rich molecules of glucose are broken down in the cytoplasm, and ATP is produced.

II. enzyme pathways in the mitochondria produce ATP through the process of fermentation.

III. enzyme pathways in the mitochondria produce ATP in a process that requires oxygen.

I, II, and III

II and III only

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.

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

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.

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

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.

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.

Plato answer

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:

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.

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:

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.

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

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.

Thus, the correct option is B.
