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
54 - 397.31 = 9u
u = 50.15m/s
Therefore, 50.15m/s is the velocity while pushing the cart.

Evan's velocity while pushing the cart towards his car would be 2 m/s.
Velocity calculationThe velocity of a moving object is the speed of the object in a specific direction. Thus, velocity is the ratio of distance covered relative to time.
Mathematically, velocity = distance/time.
Evans took a total of 9 seconds to cover 1/3 of his distance from his car.
1/3 of 54 = 18 meters.
Thus, Evan covered a distance of 18 meters in 9 seconds. His speed can be calculated as follows:
Distance = 18 meters
Time = 9 seconds
Speed = 18/9
= 2 m/s
In other words, the velocity of Evan while he was pushing the cart is 2 m/s towards his car.

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 is the answer for Tia makes a model of a glacier with clay, sand, and an ice cube. She pushes the ice cube over the clay that is covered with sand. Explain how she could use the model to show that glaciers carry soil.
The model prepared by Tia could be used to show the glaciers which carry soil as similar to the clay which carries the ice cubes and sand, the glaciers also carry various materials along with them.
What are Glaciers?A glacier is a persistent body of dense ice and other materials that is constantly moving under its own weight and force. A glacier forms where the accumulation of snow exceeds the ablation over the period of many years, often centuries.
Glaciers acquire the distinguishing features, such as crevasses and seracs, as it slowly undergoes flow and deforms under the stresses which are induced by its own weight. As it moves constantly, it abrades rocks and debris from its substrate to create the major landforms such as cirques, moraines, or fjords. Although a glacier may flow into a waterbody, it forms only on the land surface and is distinct from that of much thinner sea ice and lake ice which form on the surface of bodies of water.

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.

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.
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

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.
