Why are bacteria a necessary part of the nitrogen cycle

Answers

Answer:

Because nitrogen must be fixed in order to be used by living things, it rarely exists in its pure form. Bacteria are a very important part of the nitrogen cycle because it helps to change or fix nitrogen into a usable form. Interesting Nitrogen Cycle Facts: Plants absorb nitrogen directly from the soil.

Explanation:

Answer:

Bacteria are a necessary part of the nitrogen cycle because living things cannot use atmospheric nitrogen. The nitrogen cycle is the series of processes that lead to the interconversion of nitrogen and its compounds in the atmosphere. Bacteria are required in the nitrogen cycle because atmospheric nitrogen cannot directly use by the plant.

Answers

Answer:

D) The phospholipids act as a barrier to the passage of polar substances between the ICF and ECF

Explanation:

The plasma membrane is made up of four major kinds of molecules which include; proteins, carbohydrates, cholesterol and phospholipids.

Phospholipids are the main structure of plasma membranes. The structure of phospholipids help it serve as a barrier by playing a role in the regulation of the movement of polar molecules intracellular and extracellular fluid compartments and therefore, protect the cell.

The phospholipid structure can be described as having two ends of a head and a tail. The head end is hydrophilic or water-loving, and contains a phosphate group. The tail is hydrophobic and is made up of fatty acid chains.

Phospholipids are arranged in a bilayer with the hydrophilic head facing outwards into the ECF and ICF and the hydrophobic tail facing inwards.

Examples of phospholipids found in the plasma membrane are phosphatidylcholine and phosphatidylserine.

What are the different types of relationships found among organisms in an ecosystem?

Answers

Answer:

Five types of relationships are found among organisms in an ecosystem: competition, predation, commensalism, mutualism and parasitism.

Explanation:

A niche is the physical space in which organisms live, and includes how the organisms use the resources that are in that space, and how they interact with other organisms in that space. The interaction among organisms within or between overlapping niches can be characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism.

Symbiosis refers to a close relationship in which one or both organisms obtain a benefit.The last three types are basically defined as relationships exhibiting symbiosis, but predation and competition can also be considered as forms of symbiosis.

Predation is defined as when one organism eats another organism to obtain nutrients.

Competition is defned as when individuals or populations compete for the same resource, and can occur within or between species.

Commensalism is a relationship in which one organism benefits while the other is neither helped nor harmed. There are four basic types of commensalism. 1) Phoresy 2)Chemical commensalism 3) Inquilinism  4)Metabiosis

Parasitism is a relationship in which one organism benefits and the other organism is harmed, but not always killed. The organism that benefits is called the parasite, and the one that is harmed is the host. Parasites can be ectoparasites or endoparasites.

Mutualism is a relationship in which both species benefit. Mutualistic interaction patterns occur in three forms. Obligate mutualism is when one species cannot survive apart from the other. Diffusive mutualism is when one organism can live with more than one partner. Facultative mutualism is when one species can survive on its own under certain conditions.

In an ecosystem, organisms interact with one another in various ways, leading to different types of relationships. Some common types include: Predation, Mutualism, Commensalism, Parasitism, and Competition.

1. Predation: A predator-prey relationship, where one organism (predator) hunts and consumes another organism (prey) for food.

2. Mutualism: Both species benefit from the relationship. They provide resources or services to each other, leading to mutual advantages.

3. Commensalism: One species benefits, while the other is neither helped nor harmed. It's a one-sided relationship.

4. Parasitism: One species (parasite) benefits at the expense of the other (host), often causing harm but not immediate death to the host.

5. Competition: Organisms compete for the same resources, which may limit the growth or survival of one or more species.

These relationships play a crucial role in shaping the structure and dynamics of ecosystems and have a significant impact on population sizes and biodiversity.

A koala must eat 200 grams of leaves each day to survive. The trees in a area can provide 1380 g of leaves per day what is the maximum number of koalas that can survive in the area

Answers

Answer:

6 koalas

Explanation:

The maximum number of koalas that can survive in the area is 6.

Each koala must eat 200 grams of leaves per day.

The trees in an area can provide a total of 1380 g of leaves per day.

The maximum number of koalas that can survive in this area would be the total amount of leaves production per day divided by the amount of leaves required by each koala per day.

Hence:

Number of koala the area can support = 1380/200 = 6.9

Remember that each koala must eat 200 grams per day, therefore, the maximum number of koala that can survive in the area approximately 6.

Explanation:

Embryonic induction, the influence of one group of cells on another group of cells, plays a critical role in embryonic development. In 1924, Hans Spemann and Hilde Mangold transplanted a piece of tissue that influences the formation of the notochord and neural tube, from the dorsal lip of an amphibian embryo to the ventral side of another amphibian embryo. If embryonic induction occurred, which of the following observations justifies the claim of embryonic induction?

A) The transplanted tissue induced multiple limbs to develop on the ventral side of the recipient embryo.

B) The transplanted tissue inhibited normal cell division on the dorsal side of the recipient embryo that lead to its death.

C) The transplanted tissue had no effect on either the ventral or dorsal side of the recipient embryo so it continued to develop normally.

D) The transplanted tissue induced the formation of a second notochord and neural tube on the ventral side of the developing embryo.

Answers

Answer: Option D

Explanation:

The embryonic induction can be defined as the critical part in formation of the other tissues and organs because one cells affects the development of the other cells.

In vertebrates the notochord arises from the dorsal organiser, in amphibian the organizer is a region of vertebrate gastrulae which is when transplanted  into the ventral region of the host embryo stimulates the formation of second embryonic axis and neural tube in embryo.

This generation of second notochord in the an example of influence of one group of cell on other.

The observation that justifies the claim of embryonic induction in Hans Spemann and Hilde Mangold's experiment is (D) The transplanted tissue induced the formation of a second notochord and neural tube on the ventral side of the developing embryo.

The experiment by Hans Spemann and Hilde Mangold involved transplanting tissue from the dorsal lip of the blastopore, known as the Spemann Organizer, to the ventral side of another amphibian embryo. The observation that justifies the claim of embryonic induction would be a result showing a change in the developmental fate of the recipient embryo's cells.

Among the given options, the correct observation that would justify embryonic induction is:

(D) The transplanted tissue induced the formation of a second notochord and neural tube on the ventral side of the developing embryo.

This result aligns with the findings of Spemann and Mangold, where the organizers from the dorsal side, when transplanted, have the signaling capability to instruct the ventral cells to form structures characteristic of the dorsal side, such as the notochord and neural tube, thereby creating a second embryonic axis.

You are a molecule of nitrogen. Choose a starting
point in the nitrogen cycle and describe the
process you would go through to move through
the entire cycle.

Answers

Answer:

Explanation:

The conversion of nitrogen gas (N2) into nitrates and nitrites through atmospheric, industrial and biological processes is called nitrogen fixation. Atmospheric nitrogen must be processed, or "fixed", into a usable form to be taken up by plants. Between 5 and 10 billion kg per year are fixed by lightning strikes, but most fixation is done by free-living or symbiotic bacteria known as diazotrophs. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia, which is converted by the bacteria into other organic compounds. Most biological nitrogen fixation occurs by the activity of Mo-nitrogenase, found in a wide variety of bacteria and some Archaea. Mo-nitrogenase is a complex two-component enzyme that has multiple metal-containing prosthetic groups.[22] An example of free-living bacteria is Azotobacter. Symbiotic nitrogen-fixing bacteria such as Rhizobium usually live in the root nodules of legumes (such as peas, alfalfa, and locust trees). Here they form a mutualistic relationship with the plant, producing ammonia in exchange for carbohydrates. Because of this relationship, legumes will often increase the nitrogen content of nitrogen-poor soils. A few non-legumes can also form such symbioses.

Final answer:

The nitrogen cycle starts in the atmosphere where nitrogen fixation occurs, turning nitrogen gas into ammonia. The ammonia is then converted into nitrites and then nitrates through nitrification, which are absorbed by plant roots and transferred to animals. From there, denitrification completes the cycle by converting nitrates back into nitrogen gas and returning it to the atmosphere.

Explanation:

As a molecule of nitrogen, your journey through the nitrogen cycle would start in the atmosphere since it is made up of about 78% nitrogen gas (N2). From here, you could enter the cycle through a process called nitrogen fixation. This process is performed by certain kinds of bacteria or through atmospheric interventions such as lightning strikes which convert nitrogen gas into ammonia (NH3).

Next, in the soil, different bacteria convert ammonia to nitrites (NO2-) and subsequently to nitrates (NO3-), which are usable forms of nitrogen for plants. This sequence is called nitrification. Then, you could be absorbed by plant roots from the soil, assimilated into plant protein, and transferred to herbivores that eat the plants.

From here, other soil bacteria may convert nitrates back into nitrogen gas in a process known as denitrification, placing you back into the atmosphere to complete the cycle.

The four parts of the respiratory system through which air enters the body are the nose, pharynx, larynx, and trachea.

Parts of the respiratory system?

Nose: Air enters the body through the nostrils, where it is filtered, humidified, and warmed. Tiny hair-like structures called cilia trap particles, preventing them from entering the lungs.

Pharynx: The air then moves to the pharynx, a passage connecting the nasal cavity and the mouth. It serves as a common pathway for both air and food, directing air into the trachea and food into the esophagus.

Larynx: The larynx, also known as the voice box, contains the vocal cords. It prevents food and liquids from entering the trachea during swallowing and produces sound when air passes over the vocal cords.

Trachea: Air travels down the trachea, a tube reinforced with C-shaped cartilage rings that prevent collapse. The trachea branches into bronchi, leading to the lungs.

What are the different process of replication of virus?

The lytic cycle and the lysogenic cycle are the two ways that viruses multiply.

While some viruses employ both techniques to reproduce, others solely use the lytic cycle. Throughout the lytic cycle, the virus attaches to the host cell and injects DNA.

Lysogenic cycles vary from lytic cycles in that the virus DNA spreads through regular bacterial reproduction in lysogenic cycles.

The cell is destroyed and several copies of the virus are swiftly produced in a lytic cycle, which is more instantaneous.

A diabetic, who does not utilize insulin properly, will metabolize fats instead of glucose. A condition called diabetic ketoacidosis is a common result of excessive fat metabolism, causing blood pH values of 7.1 or less (normal range is 7.35-7.45). What has happened to the blood pH and why?A) The pH is below normal because buffers can donate OH. B) The pH is above normal (basic) because the ketones are too basic, C) The pH is not affected because the blood buffers can absorb the excess H⁺. D) The pH is below normal (acidic) because the buffering capacity was exceeded.

Answers

Answer:The correct answer to the question is option D

THE PH IS BELOW NORMAL (ACIDIC) BECAUSE THE BUFFERING CAPACITY WAS EXCEEDED.

Explanation: When insulin is being utilized well by a diabetic,glucose is metabolized because the insulin administered helps the body cells to pick up glucose from the food we eat and convert it to energy for the body to work with and function well.But when insulin is not being utilized properly by a diabetic,fats are metabolized instead of glucose that is to say that,the cells in the body are not sensitive to the glucose supplied by the food we eat which makes the body to be hypoglycemic (low blood glucose level),the body inorder to raise the blood glucose level starts breaking down stored fats in the body at a rate that is higher than normal inorder to provide energy, the liver then processes the broken down fats into a fuel that is known as ketones, these ketones are released into the blood causing the blood to be acidic,the buffering property of blood on a normal note is suppose to resist the changes in the PH of the blood,but when the buffering capacity is exceeded,there won't be any resistance to the change in the blood PH which will inturn lower the blood PH level making it acidic.

This is exactly what happened to the diabetic being described in the question.

Fluids move from areas of high pressure to areas of low pressure (Option D), which is a fundamental concept in fluid dynamics and impacts weather systems, gas behavior, and various scientific phenomena.

Explanation:

The correct statement about fluid pressure is that fluids move from areas of high pressure to areas of low pressure (option D). This principle is a fundamental aspect of fluid dynamics and is observed in various weather systems and the behavior of gases and liquids. For example, wind is an illustration of this principle as it generally blows from high-pressure zones, which are typically cooler, towards low-pressure zones, which are warmer due to the rising of less dense, heated air. Similarly, gas will move from an area of high pressure to an area of low pressure. This movement is driven by the desire to achieve equilibrium where the pressure differences are no longer present. Understanding this behavior is essential for comprehending weather patterns, ocean currents, and various engineering applications.

When a stimulus is received, it is detected by sensory receptors, transmitted to the brain or spinal cord by sensory neurons, processed by interneurons, and then a response is carried out by motor neurons causing muscle contractions.

The process from when a stimulus is received to when the body reacts involves several steps that utilize different types of neurons such as sensory neurons, interneurons (relay neurons), and motor neurons.

The stimulus is received by sensory receptors, which detect external or internal changes.Sensory neurons carry stimulus information to the brain or spinal cord.Within the central nervous system, interneurons (relay neurons) process the information and are involved in decision-making.Interneurons transfer response information to motor neurons.Motor neurons cause muscles to contract so the body can react to the stimulus, completing the response.

The entire process is often part of what is known as a reflex arc, which enables rapid and involuntary reactions to stimuli.

The primary reasons for this are:_________.
A) Prokaryotes have short generation times and large population sizes.
B) Prokaryotes have random mutations while eukaryotes can target genes for mutations; thus mutations may not accumulate as quickly in eukaryotes but they are more useful to the organism.
C) The DNA in prokaryotes is not as stable as eukaryotic DNA and is thus more likely to mutate.
D) Prokaryote mutations are less effective than eukaryote mutations in providing variation for evolution.

Answers

Answer: Option A

Explanation:

In Prokaryotes the the rate of new mutations is much more as compared to the eukaryotes. The rate of accumulation of mutation is slow in case of  eukaryote because their generation is long as compared to prokaryotes.

Prokaryotes have short generation time and large population size which enables them to accumulate the mutation quickly.

The machinery is also not that complex when it comes to prokaryotes. Transduction, conjugation and tranposable elements. So, the changes during these processes leads to mutation in the prokaryotes and can be observed quickly due to their small generation.

Homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become ill and may die. Individuals homozygous for the sickle-cell trait (ss) have sickled red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the hemoglobin disorder. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause death. In addition, the heterozygotes tend to survive better than either of the homozygous conditions as they are resistant to malaria. If 16% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria? which of the following statements is TRUE about committees? a.Committees have the final vote on the bill b.Committees veto bills which they disagree c.Committees only make recommendations about bills d.Committees make the final decision on amendments to a bill Drag the tiles to the boxes to form correct pairs.Match each excerpt from a media article to its purpose.A) to entertainB) to persuadeC) to inform What two nations did Truman help resist communism there is $412 and 3 purses how much is in each purse????
