Nitrogen Cycle - High School STEM Case
Answer:
In general, the nitrogen cycle has five steps:
Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
Nitrification (NH3 to NO3-)
Assimilation (Incorporation of NH3 and NO3- into biological tissues)
Ammonification (organic nitrogen compounds to NH3)
Denitrification(NO3- to N2)
Explanation:
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
The nitrogen cycle is the biogeochemical process through which nitrogen is changed into a variety of chemical forms as it moves across ecosystems in the atmosphere, on land, and in the sea.
What is nitrogen cycle?In the nitrogen cycle, nitrogen circulates through both living and non-living objects, including the atmosphere, soil, water, plants, animals, and microorganisms. tiny living things that are ubiquitous and typically only have one cell.
Organic material in soils can decompose or break down as a result of bacteria. Nitrogen must alter its forms in order to progress through the cycle's many stages.
The five steps of nitrogen cycle is volatilization, mineralization, nitrification, immobilization, and denitrification. The fixation process is known as volatilization in this image because soil bacteria convert nitrogen gas (N2) into volatile ammonia (NH3).
Therefore, The nitrogen cycle is the biogeochemical process through which nitrogen is changed into a variety of chemical forms as it moves across ecosystems in the atmosphere, on land, and in the sea.

Dengue fever is an infectious disease of humans that is caused by a virus. There are four main viral strains, and an individual can never be infected by the same strain twice. However, a second infection can occur by any of the other strains. The severity of the second infection depends on the identity of both the strain that caused the first infection and the strain causing the second infection, as well as the order in which these were acquired.
Required:
How many different levels of severity are possible for an individual acquiring a second infection
Answer:
12
Explanation:
Suppose the four different strains are P, Q, R, S. Thus, the first infection can be from any of the four strains and it occurs in 4 ways.
Since an individual cannot be infected again with the strain from which he/she is been previously infected;
Then, at the second time;
The possible number of strain to be infected with = 4-1 = 3 ways
Thus; the number of possible different levels of severity can be viewed by forming two lettered word P, Q, R, and S without repetition which is:
= 4 × 3

A three letter base sequence on a mRNA molecule called a ____ translates for a particular amino acid.
Answer:
anticodon sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule.
The correct answer is codon. Codons present in mRNA molecules translate for a particular amino acid.
What is a codon?A codon is a group of three DNA or RNA nucleotides that codes for a particular amino acid or protein synthesis halt signal. Four nucleotides make up the language of DNA and RNA molecules, while 20 amino acids make up the language of protein molecules.The key to translating between these two languages is provided by codons. The entire set of codons—each one corresponding to a single amino acid—is referred to as the genetic code. During translation, an mRNA's codons are read starting at a start codon and continuing until they reach a stop codon. The order of amino acids in a protein, from the N-terminus (methionine) to the C-terminus, is determined by mRNA codons, which are read from 5' to 3'.Thus, a codon is a three-letter base sequence that translates for a particular amino acid.

What was the ancient view of the world and animals? Give an example using Aristotle’s interpretation
Answer:
800 million years ago, the first animal life began on Earth. And discussions were seen between different scientists based on the relationship between animals and humans. As per Aristotle (Father of Biology), humans were different from that of the animals. He stated that humans share all the characters which manifest themselves in different types of soul that the animal possess, with addition to a rational soul which was exclusively found only in humans. As per Aristotle there were three different types of soul, those were:-
Nutritive Appetitive RationalThe first two soul were found in every living organisms including the plants. But the last one, the rational soul was unique to Humans as per Aristotle.
According to Aristotle, the ancient world looked in a manner that the Earth was the located at the center of the Universe. And all other celestial bodies rotated around the Earth. The Earth was termed to be stationary. And it was assumed that in sub lunar region, there were four basic elements- earth, air , fire and water . And all of these elements had an unique essential property based on their movement. Where, the Earth moved towards the centre of the Universe. The water too moved towards the centre of the universe but not in a degree of which the earth moved. The air moved above the Earth and the water. And the fire moved away from the centre of universe. It was also said that the heaven was made up of a weightless substance that was called as to be 'aether'.
Which of the following is not a good method in examining fossils anatomical features of
living organisms?
O a. Homologous structures
O b. Vestigial structures
O c.
Index fossils
O d. Analogous structures
Answer:
d. Analogous structures is not a good method in examining fossils anatomical features of living organisms.
Explanation:
Analogous structures are physical characteristics that are similar in different organisms due to convergent evolution, rather than being inherited from a common ancestor. While analogous structures can provide valuable information about the environment and adaptations of living organisms, they are not helpful in examining the fossils of ancient organisms because they do not reflect the evolutionary relationships between different species. Homologous structures, vestigial structures, and index fossils are all useful methods in examining fossil anatomy, as they can provide insights into the evolutionary relationships and characteristics of ancient organisms.
Evan was 54 meters away from his car adter shopping. It took 9 seconds to push a shopping card one third of the way directly to his car at a constant velocity. What was his velocity whilehe was pushing the cart ?
The velocity while Evan was pushing the cart is 50.15m/s.
How to calculate velocity?The velocity of a moving body can be calculated using one of the following equations of motion as follows:
s = ut + ½at²
Where;
s = distanceu = velocityt = timea = accelerationAccording to this question, Evan was 54 meters away from his car after shopping. It took 9 seconds to push a shopping card one third of the way directly to his car at a constant velocity. The velocity used is as follows:
54 = (u × 9) - ½ × 9.81 × 9²
54 = 9u - 397.31

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

At times, a cell may be infected with a virus, or there may be an organelle within the cell that is not working any longer. A cell needs to remove such waste materials to maintain its well-being. Enzymes within the cell break down these waste materials, and the broken down materials are released from the cell. Which organelles within the cell are most responsible for processing the waste and removing it from the cell?
Answer:
Lysosomes.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria includes; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, ribosomes, chromosomes, endoplasmic reticulum, vesicles, lysosomes, etc.
Lysosomes are organelles within the cell that are most responsible for processing waste and removing it from the cell.
Basically, they are responsible for absorbing materials and breaking the materials taken in by the cells because they're typically rich in various acid hydrolases or hydrolytic enzymes such as phosphatases, lipases, nucleases, proteases, etc.
