Answer:

Adenine, guanine, cytosine and thymine.

Explanation:

The full form of DNA is deoxyribonucleic acid. It is a double-stranded molecule and each strand of DNA is composed of nitrogenous bases, deoxyribose sugar, and phosphate group.

There are four types of nitrogenous bases that are present in DNA. The four bases are adenine, guanine, thymine, and cytosine. Adenine and guanine comes under purine and thymine and cytosine comes under pyrimidine.

Adenine and thymine makes two hydrogen bond with each, guanine and thymine makes three hydrogen bond with each other.

C for you, A for PLATO/Edmentum user.

DNA contains all instructions and entire information which is written on genes this is the reason why a mistake and transcribing DNA message affect your ability to catch a killer. An indiviudal can catch the thief by complete DNA information but if any mistake occurred, then it will become difficult to detect the crime of people.

Transcription errors during DNA replication can lead to mutations that, if not corrected, may affect forensic investigations by altering genetic markers crucial for identifying suspects or implicating innocents.

During DNA replication, the accuracy of copying information by enzymes like DNA polymerase is crucial. Typically, DNA replication is a highly accurate process, where enzymes such as DNA polymerase are responsible for copying the cell's DNA. However, they sometimes make mistakes, like inserting the wrong base. These errors, if not corrected by proofreading and repair mechanisms, can lead to permanent changes in the sequence known as mutations.

When it comes to catching a killer using genetic evidence, the ability to faithfully transcribe and replicate DNA is paramount. If mistakes are made and not corrected, they could lead to incorrect interpretations of genetic evidence, potentially implicating the wrong person or missing the true culprit.

Therefore, errors in transcribing DNA can result in mutations that impact protein functioning and have serious consequences like cancer.

Answer: The correct answer is option 3) The amount of matter within the system remains the same and 5) The cycle has a well-defined starting and stopping point.

A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.  

In a closed system, the cycle has a well-defined starting and stopping point.

Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 1) and 5)

The statements 3 and 5 can be two generalization made by the information of a closed system.

Answer:  The species are poorly related to each other.

Darwin gave information for evolution as "descent with modifications" it involves a process in which species change and gives rise to a new species over generations. He proposed that the evolutionary history of life forms a branching tree with many level as a new species evolve. All species can be traced back to a common ancestor. Each newly evolved species will have one or more characteristics in common as that of the old species.

In species with no common ancestor will not have any similar characteristic in common such species cannot be evolutionary linked and cannot be placed and linked in an phylogenetic tree.

The correct answer is an active site.  

The active site, in biology, refers to the region of an enzyme where the molecules of substrate combine and goes through a chemical reaction. The active site comprises of the residues, which produce temporary bonds with the binding site (substrate) and residues that catalyze a reaction of that substrate, that is, the catalytic site.  

Active site is a specific region of an enzyme where a substrate binds and the chemical reaction occurs.

The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.

It consists of two sites:

The answer is option C - Physical Oceanography.

One can study the Coriolis Effect under Physical Oceanography.

Physical oceanography is defined as the study of the physical conditions and physical processes within the ocean. It specifically studies the motion and physical properties of ocean waters.

Answer:

Option (C)

Explanation:

Physical oceanography is the branch of oceanography that deals with the study of all the physical processes that take place within an ocean. It illustrates how the waves in the oceans are generated, the factors that affect them, tidal effects, effects of Coriolis force, transportation of sediments from the oceans to the coastal regions and again back to the oceans. It also studies the changing effects of latitudes and interaction patterns between the ocean waves and the atmosphere.

coriolis force is the force that initiates due to the rotation of earth. It creates a deflection towards the right while moving in its wind direction.

Hence this Coriolis effect is studied in the field of physical oceanography.

Thus, the correct answer is option (C).

Hello,

Question - How do the daughter cells that result from mitosis compare with one another?

Answer - After mitosis it results in daughter cells that have half as many chromosones per cell.

Why - "Preparing for mitosis, a cell produces a copy of its DNA. Homologous pairs are separated, and the two resulting daughter cells have half as many chromosomes per cell."

The option A is the correct option. The fungi share a mutualistic association with the trees.

Mutualism or interspecific cooperation is the way two organisms of different species exist in a relationship in which each individual fitness benefits from the activity of the other. And in this case, both plant and fungi are benefited by each other. The plant provides food and habitat for the living of fungi and fungi, in turn, decompose dead organic matter to provide simple compounds to plants.

While in commensalism only one either plant or fungi can be benefited. And it is also not a parasitic interaction.

Answer:

Anton Von Leeuwenhoek in 1674, observed a drop of pond water under a microscope. He observed living microbes like bacteria and protozoa. He is commonly known as  ''the Father of Microbiology" and he is the first microscopists and microbiologists.

Anton van Leeuwenhoek was a scientist who discovered microbes in pond water by using a microscope.

Anton van Leeuwenhoek is generally recognized as the father of microbiology. Both protists and bacteria were discovered by him. He was not only the first to view this hitherto unseen world of "animalcules," but he was also the first to contemplate looking—certainly, the first with the capacity to see.

He most likely first noticed bacteria in 1674, followed by protozoa a few years later. He was able to separate those "very little animalcules" from a variety of sources, including human mouth and intestine, pond, and well water.

T = const.

P1 = 123 kPa

V1 = 123.13 L

V2 = 28.15 L

P2 = ?

This is an example of Boyle’s law which describes how the pressure of a gas tends to increase as the volume of the container decreases, meaning that P*V=const. For comparing the same substance under two different sets of conditions, the law can be expressed as P1*V1=P2*V2

P2=P1V1/V2

P2=123kPa*123.13L/28.15 L

P2=538.01 kPa

- It can't be a bryophyte because bryophytes are non-vascular.

- It can't be an angiosperm because angiosperms produce seeds.

- It can't be a gymnosper because gymnospers also produce seeds.

So, this means it's a pteridophyte because pteridophytes produce sprores insted of seeds, are vasuclar (meaning they have a vascular tissue).

Density independent means that the limiting factors are not dependent on the number of individuals in the population. For example, an earthquake will kill individuals in a population no matter if the population is large or small.

A density dependent limiting factor means that the effect is dependent on how many individuals there is in a population. For example, a disease will have greater effect in a large population since it would be spread to more individuals.

Density-independent factors affect the population irrespective of its size and include elements like weather and natural disasters. Density-dependent factors vary depending on population density and include biotic factors like predators and disease. In real-life situations, both types of factors can interact to affect the population.

Density-independent and density-dependent limiting factors are both environmental conditions that can influence the population size. Density-independent factors affect the mortality of a population irrespective of its density. These are usually physical or chemical in nature, such as weather, natural disasters, or pollution. For example, deer may be killed in a forest fire irrespective of how dense their population in that area is.

On the other hand, density-dependent factors have varying effects depending upon the population density. These are mostly biological in nature, such as predation, competition, accumulation of waste, and diseases caused by parasites. When the population is denser, diseases can spread more rapidly, leading to increased mortality. Moreover, in situations with high intraspecific competition, the reproductive rates are generally lower, which can reduce the population's growth rate.

In real-world scenarios, regulation of population is complex and often involves an interaction of both these types of factors. A dense population experiencing mortality from a density-independent cause, like a severe winter, can recover differently than a sparse population.

If a zero is found between significant digits, it is significant.

It is not significant when it is found in front a normal number for instance in a decimal if it is behind the number it is significant.

Answer: All zero’s preceding the first integers are never significant

All zeroes used solely for spacing the decimal point are not significant.

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.

All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.

All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.

All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.
