The carbon dioxide in the breathed out air is a by-product of the process of cell respiration. In respiration, a molecule of carbohydrate is converted into a CO2, H20, and energy which is released in form of ATP.
Answer 2:All plants belonging to kingdom Plantae and plant-like organism like photosynthesizing bacteria need CO2 to survive. They use carbon dioxide in food making process, photosynthesis.
Answer 3:Amount of CO2 in the air: 0.03%Amount of CO2 in the breath: 4%Hence it is proved from above statistics that breath has more carbon dioxide than air.
Answer 4:There are two sources of CO2 in the air. Which are the following:
Human sources: It includes activities of human involvement and release of CO2 artificially as in cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.Natural sources: Release of CO2 by natural processes as in decomposition, ocean release and respiration.Answer 5:The major ecological effect is global warming.As CO2 is known as the greenhouse gas because it gives a greenhouse effect. Elevating concentration of CO2 in air forms a layer or sheath of CO2 over the earth which allows the entry of sun rays and stop it from reflecting back, trapping sun rays around earth increasing the temperature of earth day by day. It also causes plants to provide less evaporative cooling because in high concentration CO2 stomata shrink through which normally evaporation occurs when stomata are open.Answer:
Although CO2 is generally known as a dangerous and nocious gas, the truth is that without it, life would not be possible, both in plants and animals. CO2 plays a vital part in animals in the breathing pattern and too low amounts of it may also bring problems. Given this background, the answers to your questions, would be:
1. CO2 is one of the results of energy production in organisms. Usually, when an organism produces ATP, the energy molecule, it will consume certain chemicals (oxygen, hydrogen, carbon, and others) that when they react, end up generating certain products: water and CO2. This CO2 is then expelled by the lungs, at least in animals and humans. Plants, however, during daylight, use this gas for food production, and in nightime switch their systems to expel CO2. This is why sleeping with a plant can be dangerous.
2. Bacteria are capable of using CO2 and from it generating pure oxygen, water and other products. Also, plants, in general, especially photosynthetic ones, need CO2 for their energy production processes. Algae, is also capable of using CO2, and thus oxygenating the oceans. Finally, there are fungi also capable of using CO2 and producing oxygen and water.
3. As of 2019, the amount of CO2 present in our air was of 413.0 parts per million, an all-time high. In human breath, the amount of CO2 released is of 500 lt per person, and in total, per year, people in the world can release about 2500 million tons, about 7% of the total amount released into the atmosphere.
4. Animal breathing, as well as certain activities like burning coal, wood, animal and human waste, waste management, are all examples of activities outside of breathing, that cause CO2. Plant decay, and animal carcass decay will also release CO2 into the atmosphere.
5. Probably the biggest effect that excessive CO2 dissolved in water, bringing up acidity in it, has, is, the production of acid rain. This has also proven devastating for crop growth, and agricultural production, as well as animal raising. The second is the production of further greenhouse effects. As the water evaporates, releasing more CO2 into the atmosphere, the situation becomes even graver with time. Today, we are witnessing rainfall that damages entire fields because of its higher acidity, and changes in atmosoheric conditions due to this excessive CO2.

How would a mistake and transcribing DNA message affect your ability to catch a killer
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.
What do you notice about the ratio of hydrogen to oxygen in each monosaccharides
DNA is made of four different bases: _______, _______, _______, and ______.
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.
What are the differences between density-independent and density-dependent limiting factors?
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.
Explanation: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.

From approximately 240 to 66 million years ago, dinosaurs dominated most of the land habitats on Earth. Around 66 million years ago, most dinosaurs went extinct when an asteroid struck the Earth. Mammals, which were much smaller and lived primarily in underground habitats, were able to avoid extinction. Mammals then underwent an adaptive radiation to develop a wide variety of new species. Which statement best explains why the adaptive radiation of mammals was possible?
A.
New species were able to form because the change in environmental conditions increased the mutation rate of mammals.
B.
Populations of mammals were able to rapidly increase since the Earth had a single, large habitat after the asteroid hit.
C.
Mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
D.
The loss of predation decreased the rate at which mammals became reproductively isolated from one another.
The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.

Their fossils are too large to study.
They have different physical characteristics.
A link is yet to be discovered.
The species are poorly related to each other.
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.

Mycorrhizae are associations formed by fungi that grow on the roots of trees. These fungi penetrate into the roots of the trees. The trees produce energy through photosynthesis and share it with the fungi. The fungi act as decomposers, breaking down dead organic matter to provide nutrients for the trees to grow. What kind of a relationship is exhibited in this example?
A. The fungi share a mutualistic association with the trees.
B. The fungi are a parasite for trees.
C. The fungi share a commensal association with the trees.
D. The fungi are predators for the trees.
The option A is the correct option. The fungi share a mutualistic association with the trees.
Explanation: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.

Which two generalizations can be made based on what you know about cycles of matter in a closed system?
1 New matter is added, and old matter is destroyed.
2 Matter changes its physical form, allowing it to return to its original state.
3 The amount of matter within the system remains the same.
4 Matter and energy can cross the boundaries of the system.
5 The cycle has a well-defined starting and stopping point.
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.
Explanation:A closed system is system in which neither matter nor energy cannot cross the boundaries of the system.So the statement 3 which is the amount of matter remains same in the system is correct one on the bases of the law of conservation of mass.This law states that neither mass and energy can be created nor destroyed but they can change from one form to another form.In the given system, reaction of matter is in cyclic form, the starting and stopping points of reaction can be well defined on the basis of reaction.Haploid sperm and egg are produced via meiosis.

A gas with constant temperature has a pressure of 123 kPa and a volume of 123.13 L. A pressure change caused the volume to decrease to 28.15 L. What is the new pressure?
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
