Answers

Decomposers are organisms that convert the carbon in organic compounds into carbon in carbon dioxide.

Non-photosynthetic organisms convert the carbon in organic compounds into carbon in carbon dioxide.

What are organic compounds?

The process by which organisms that engage in photosynthetic growth, like plants and algae, convert inorganic carbon compounds (typically carbon dioxide) into organic carbon compounds examples of processes that cause carbon to transfer from one reservoir to another include photosynthesis, respiration, and combustion.

The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, such as oxygen, to generate significant amounts of energy that are used to power the major production of ATP.

Therefore, cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a substance known as adenosine triphosphate.

Which of the following is not a piece of molecular evidence supporting the endosymbiotic theory?

Answers

The mitochondria and chloroplasts are much different in structure than bacteria. Hence the correct option is a.

One piece of molecular evidence supporting the endosymbiotic theory is the similarity between the DNA of mitochondria and chloroplasts and that of bacteria. This similarity suggests that mitochondria and chloroplasts may have originated from free-living bacteria that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.

Additionally, the presence of ribosomes in mitochondria and chloroplasts that resemble those found in bacteria further supports this theory. Moreover, the mechanism of division by fission, which is similar to bacterial reproduction, observed in some organelles like mitochondria and chloroplasts provides further evidence for their bacterial origins.

However, the structural differences between mitochondria, chloroplasts, and bacteria do not directly support the endosymbiotic theory but rather suggest evolutionary adaptations that have occurred over time. Therefore, option A is not a piece of molecular evidence supporting the endosymbiotic theory. Hence the correct option is a.

2.) The seafloor holds promise as a source of many natural resources, including valuable metals. As demand for natural marine resources increases, mining these resources from the seafloor also increases. One concern of seafloor mining is the disruption of the seafloor habitat. Which of the following describes the most likely impact of seafloor mining on the surrounding marine environment?

A.) Alteration in seafloor sediments rich in carbon would cause loss of species and an unbalanced population in marine food webs.

B.) Increased levels of metals in the ocean would result in decrease of marine bivalves due to weakened shells.

C.) Methane gas would pollute the marine environment and cause an overabundance of bacteria that feed on it.

D.) Nonrenewable resources in the marine environment would become depleted and affect the balance of the ecosystem.

Answers

The answer would be A. it would not be D because marine life does not concern metals and other resources like that. It would be A because life needs carbon, it already does, but it needs to be well balanced and not disrupted.

Answer: A.) Alteration in seafloor sediments rich in carbon would cause loss of species and an unbalanced population in marine food webs.

Explanation:

The seafloor mining will have a drastic impact over the sea ecosystem. The mining process will expose the partially decomposed organic matter to the sea water. This will result in the increase in abundance of the organic carbon in the sea water. This will readily absorbed by the aquatic plants but the increase in abundance will likely to kill sea animals because carbon is the waste material discharged by the organisms and oxygen is the basic requirement for all the cells of the body. This will negatively influence the populations of the marine food webs.

The client is admitted with paroxysmal supraventricular tachycardia at a rate of 140 beats per minute. the client's blood pressure is 110/55 mm hg, and the client is asymptomatic except for a "fluttering feeling" in the chest. which treatments should the nurse be prepared to administer

Answers

The correct answers are: IV adenosine, IV beta blockers, IV amiodarone, or IV calcium channel blockers. Supraventricular tachycardia is a kind of abnormal heart rate and the pathology lies in the atria (hence supraventricular). This is seen in the ECG as narrow QRS complexes. While all the management is applicable for supraventricular tachycardia, the first line is IV adenosine to normalize the heart rate. If this doesn't work, then IV amiodarone can be the second line. After these interventions are done but with no avail, cardioversion should be done. 

For the eighth observation (i=8), identify the animal phylum, xi, and yi.

Answers

The correct answer is "Phylum Urochordata: xi = 25; yi = 77".
The table presented in this exercise can be used as a tool to examine any connection between the microRNA (miRNA) diversity and the morphological complexity in a phylum. The Xi column represents the average number of miRNAs in a phylum, while the Yi column represents the average number of cell types in that phylum. The eight observation of this table refers to the data obtained from the phylum Urochordata.
MicroRNAs are small non-coding RNAs which regulate gene expression post-transcriptionally. They are used as phylogenetic markers as they have a very low rate of evolution. Also, they are very useful because it has been shown that phyla with very high levels of morphological innovation have high numbers of miRNA concentration.

How did photosynthesis lead to the development of animals living on land?

Answers

Photosynthesis was essential for filling the Earth atmosphere with oxygen that is necessary for metabolic processes of all animals.
Only after the plants colonized the land and raised the levels of oxygen in the atmosphere to levels high enough to sustain animal respiration did the animals move from aquatic to terrestrial way of life.
Around 2.4 billion years ago, the first photosynthetic organisms appeared and used inorganic matter like carbon dioxide and water to produce glucose, with oxygen released in the atmosphere. Because of this, oxygen levels rose; this is called the Great Oxygenation Event. Through time, photosynthetic organisms evolved to live in land (now as plants). As concentrations of oxygen in the atmosphere became higher, marine animals evolved to utilize oxygen readily available from the atmosphere (rather dissolved in water) hence the evolution of marine animals to land animals capable of respiration in land.

Which factor would not increase the production of glucose by photosynthesis in plants?

Answers

Final answer:

Lack of water would not increase glucose production by photosynthesis in plants because water is crucial for the light reactions to produce NADPH and ATP, which are needed in the Calvin cycle to synthesize glucose. Insufficient water impacts the entire photosynthetic process, leading to decreased glucose production.

Explanation:

A factor that would not increase the production of glucose by photosynthesis in plants is a lack of water. Water is essential for the light reactions of photosynthesis, where water molecules are split to form oxygen, electrons, and protons. These electrons and protons are then used to generate NADPH, which, along with ATP produced in the light reactions, is used in the Calvin cycle to synthesize glucose. Without sufficient water, these processes can't occur optimally, and the production of glucose by photosynthesis would decrease.

Regarding the statement about how an increase in temperature causing faster diffusion of CO2, and consequently, a potential increase in the rate at which plant leaves lose CO2; if all other conditions are favorable for photosynthesis, the increased loss of CO2 may lead to reduced availability of CO2 for the Calvin cycle. This can result in a decrease in photosynthesis (as per option d.), since there would be less CO2 to be fixed into glucose.

The products of the Calvin cycle are glucose and other sugar molecules as well as the regeneration of the molecule RuBP which is necessary for the cycle to continue.

If a plant lacks a photosystem II complex due to a mutation, it would not be able to initiate the light-dependent reactions of photosynthesis, leading to a failure to produce the essential compounds like ATP and NADPH required for the Calvin cycle, thus disrupting the synthesis of glucose.

Plants that lack sunlight or sufficient water would not be able to perform photosynthesis efficiently, which would impact not only the plant's survival but also the organisms that rely on those plants for food, leading to broader ecological consequences.

Exposure to only red light can still support photosynthesis, although the rate may vary depending on the specific species of plant and its adaptations to light conditions (as per options b. and c.).

Final answer:

Factors not increasing photosynthesis include a lack of water or insufficient CO₂, both crucial for the Calvin cycle. A mutation removing photosystem II would inhibit photosynthesis, and only red light exposure can also affect the rate of photosynthesis. Plants without sunlight or water would produce less glucose, impacting dependent organisms.

Explanation:

Factors that do not increase the production of glucose by photosynthesis in plants include a lack of water or inadequate carbon dioxide (CO₂). A lack of water would prevent hydrogen ions (H+) and NADP+ from forming NADPH, which is essential for the Calvin cycle of photosynthesis. Not enough CO₂ would limit the number of carbon molecules available to be fixed into glucose during the Calvin cycle. Additionally, an increase in temperature might lead to a faster loss of CO₂ from plant leaves, affecting the Calvin cycle by slowing it down due to insufficient carbon to fix in the system. This could potentially lead to lower glucose production if light and water are adequate.

The products of the Calvin cycle, which depend on carbon fixation, are carbohydrates and regenerated RuBP (ribulose bisphosphate), which is critical for the cycle to continue. If a plant had a mutation that eliminated its photosystem II complex, it would not be able to split water molecules to generate oxygen, hydrogen ions, and electrons essential for the formation of NADPH and ATP, thus hampering the photosynthetic process and preventing glucose production.

With only red light exposure, the rate of photosynthesis in a plant could potentially decrease or follow a complex pattern where it decreases and then increases, depending on the specific wavelength of the red light and the plant's individual response to it. For plants lacking sunlight as an energy source or sufficient water, photosynthesis would be inhibited, reducing glucose production and potentially affecting those organisms that rely on plants for survival.

A clerk can sort 375 sheets of per hour. If there are 225 sheets in an inch, how long will it take her to file 125 inches of loose leaf?

Answers

Answer: 75hours

Explanation:

If there are 225 sheets in one inch that means that in 125 there will be 28,125 sheets because you will have to multiply. And if you can sort 375 pero hour that will mean than in 75 hours you will sork all sheets because 28,125 divided by 375 sheets pero hour will give 75 hours.

125 inch * 225 sheet/ inch= 28,225 sheets

28,225 sheets divided by 375 sheets/hour=75 hours

It will take them 75 hours to file all the sheets in the bundle.

What is speed?

The rate of change of position of an object is called speed. Speed is a scalar quantity, which means the measurement of direction is not important in the case of speed.

That is why it is different from velocity which is a vector quantity. In velocity, the rate of change of motion is measured in a particular direction.

Because speed measures the rate of a change in motion, it is not useful to be used in this case.

In this case, the rate of filing is 375 sheets/hour.

There are 225 sheets in an inch and a total of 125 inches of sheets.

So the total number of sheets is equal to

225 × 125 = 28125 sheets.

Rate of filing = 375 sheets/hour

So, 28125/375 = 75.

Therefore the time required to file all of the sheets is equal to 75 hours.
