Concept hierarchy is the process of classifying information or concepts into a hierarchy or a particular partial order. It is used to define knowledge in a concise, high-level manner and to make it possible to mine that knowledge at various levels of abstraction. Thus, option B is correct.
What is the importance of conceptual hierarchy?Data can be transformed into various granularity levels using the notion of hierarchies. For instance, sales patterns related to particular areas or nations as well as specific branch locations may be discovered using data mining.
Therefore, Enrique made a list of things he needed from the store.He named every fruit, followed by every dairy product, and then a few things for cleaning the house. Enrique’s list is an example of a( conceptual hierarchy)

ke the collar of an airbag helmet. The
One morning, a technician finds they have
ollars. How many more meters of fabric
Answer:
163 fabric needed to make 250 collars.
Explanation:
Given that,
Length = 1.5 m
Width =137 cm
Number of order = 250
Use fabric = 65%
We need to calculate the actual length need to make a collar
Using given data
[tex]Actual\ length =Length\times use\ fabric[/tex]
Put the value into the formula
[tex]Actual\ length =1.5\times\dfrac{65}{100}[/tex]
[tex]Actual\ length=0.975\ m[/tex]
We need to calculate the total length of fabric
Using formula for total length
[tex]total\ length=Actual\ length\times Number\ of\ collars[/tex]
Put the value into the formula
[tex]total\ length=0.975\times250[/tex]
[tex]total\ length=243.75\ m[/tex]
We need to calculate the number of fabric
Using formula for number of fabric
[tex]Number\ of\ fabric=\dfrac{total length}{length}[/tex]
Put the value into the formula
[tex]Number\ of\ fabric=\dfrac{243.75}{1.5}[/tex]
[tex]Number\ of\ fabric=162.5\approx 163[/tex]
Hence, 163 fabric needed to make 250 collars.

Give ONE suggestion for how humans can lessen their impact on Earth.
Answer:
Humans must decrease the harmful impact they have on earth or else the human population could go extinct forever. One way to do this is to inform the people on climate change and its effects. Recycling, using metal straws, carpooling, cleaning up beaches, pulling unncessary plugs in your house to reduce electricity usage, and doing so much more can help reduce the risk of climate change and help the world become a much healthier and stable place for humans, plants, animals, and the environment.

The age of a cell is related to structures called ____.
*Talking about cancer cells*
Will report stupid answers.
Answer:
Telomeres
Explanation:
Telomeres are structures at the ends of chromosomes that protect the DNA. They get shorter as we age. When they become too short, the cell undergoes apoptosis (programmed cell death ) to avoid having cells with DNA that could become damaged.
However, cancer cells can sometimes overcome this, and can avoid telomere shortening, or avoid apoptosis once telomeres have become too short. This allows cancer cells to divide indefiniately.

A farmer is harvesting this seasons strawberries to be sold. A farmer noticed his spotted strawberries grow better in all weather types and resist insects on their own. The next season, the farmer decided to get rid of the original strawberries and plans to only plant spotted strawberries. What is a result of this farmer's action?
Answer:
This question is incomplete as some part of the questions are missing and it also lacks options. The complete question is:
A farmer is harvesting this seasons strawberries to be sold. The farmer discovered spotted strawberries which appear to grow well in all weather types and resist insects on their own unlike other varieties of strawberries that require additional pesticides to resist insects.Pesticides are substances used to repel or control forms of animal life considered to be pests.The next season, the farmer decided to get rid of the original strawberries and plans to only plant spotted strawberries. What is a result of this farmer's action?
A. A decrease in strawberry production
B. An increase in the use of pesticides on the farm.
C. A decrease in genetic diversity of the strawberries.
D. An increase in genetic variation of the strawberries
The answer is C
Explanation:
According to this question, a farmer who is preparing to harvest strawberries for sale noticed that spotted varieties of strawberries grew better in adverse conditions, including pest resistance, than every other strawberry variety. He then decided to plant only the spotted strawberries the following season. This means that he got rid of every other varieties.
Based on this, we would realize that that farmer is trying to naturally solve the problem of pest infestation, hence, REDUCING the use of pesticides on the farm.
- Also, spotted strawberry can be produced in mass, which will not affect/reduce the production of strawberries.
- Genetic diversity refers to the total number of different alleles, which is responsible for varying traits, in the genetic makeup of an organism. The farmer's action of planting only one variety of strawberries will DECREASE GENETIC DIVERSITY IN THE STRAWBERRY SPECIES.
what best describes a tetrad
Answer :
4 chromatids.
Explanation: the world needs answers , I can provide
Tetrad is best described by two sister chromatids, coming together to form a four-part structure.
A tetrad, also known as a bivalent, is a structure that forms during meiosis I in sexually reproducing organisms.
During prophase I of meiosis I, homologous chromosomes pair up and become physically connected along their lengths.
This connection between homologous chromosomes is called synapsis.
As a result of synapsis, a tetrad is formed, which consists of two pairs of sister chromatids, one pair from each homologous chromosome.
The tetrads play a crucial role in the process of genetic recombination or crossing over. During prophase I, while the tetrads are formed, the genetic exchange can occur between the non-sister chromatids of the homologous chromosomes.
Thus, a tetrad is a four-part structure formed by two pairs of sister chromatids that come together during meiosis I.

List the three types of fibers possible in connective tissue and a brief description of each
Answer:
Look below
Explanation:
collagen fibers, elastic fibers, and reticular fibers.
Collagen fibers-Collagen fiber is made from fibrous protein subunits linked together to form a long and straight fiber
Elastic fibers-a yellowish fiber composed chiefly of elastin and occurring in networks or sheets which give elasticity to tissues in the body.
Reticular fibers-Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue composed of type III collagen secreted by reticular cells.
Answer:
Single-mode cables include one glass strand (the core), surrounded by three layers of other material (the cladding, the buffer, and the jacket). They are relatively more expensive than other cables. Single-mode cables can transmit data at fast speeds over long distances (up to 62 miles) and offer higher bandwidths.
Multi-mode cables have more than one strand and transmit light along many paths. They support very fast speeds of between 10 Mbps to 10 Gbps over short distances (2,000 and 1,000 feet, respectively). Although these cables can transmit data over short distances, they will distort data over long distances.
Plastic optical fiber cables consist of plastic fibers instead of glass fibers. They are cheaper than glass optical fiber cables. They are similar to multi-mode cables; however, they are only reliable over short distances.
