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.

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.

only 65% of the length of fabric they need to make the collars. How ma
are needed to be able to make all 250 collars? Show your work.
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.

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.

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.

O Extreme temperature
O Low blood sugar level
O Elevated blood pH
O All of these
"Explain the process of how the human circulatory system delivers blood that is rich with oxygen to all parts of the body and then returns the blood to the lungs and completes this cycle over and over"
"List 5 senses and how does the nervous system including the brain and spinal cord play a part in the process of each of these 5 senses."
"Please compare and contrast the difference between photosynthesis and cellular respiration. Please include glucose, water, oxygen, carbon dioxide and the sun"
Answer:
The circulatory system of our body complies with the gas exchange in the pulmonary alveoli, there the oxygen enters and binds to a protein which oxidizes it, this protein is allosteric, and it is called hemoglobin, this hemoglobin travels the human body capturing every need punctual of each organ, some organs will demand more or less oxygen according to the metabolic state of the human system.
Once oxygen is in front of an organ with few partial pressures of oxygen, it is released from the hemoglobin and this protein changes its conformation and then re-oxidizes when passing through the pulmonary alveoli.
It is important to clarify that hemoglobin is found in red blood cells, and these in the blood where they are pumped and distributed by the cardiovascular system.
Sense of taste, smell, touch, hearing and sight.
In the spinal cord, it is related more than anything those touch receptors in charge of executing reflexes against injuries or harmful conditions, such as touch receptors that are in charge of measuring temperature and measuring the limb's withdrawal response to excessive heat or burn .
As for the central nervous system and the cortex, they are responsible for managing the signals sent by sensory neurons, associating them with feelings, memories and experiences, such as taste and smell.
Photosynthesis is a process where energy currency for plants is obtained as a product, it requires ultraviolet light and carbon dioxide as products, where plant chlorophyll intervenes and oxygen is released to generate food autonomy for plants.
On the other hand, the respiratory chain is a process where proteins are oxidized sequentially to allow the gas exchange of those living organisms.
Explanation:
Explanations one and three are related because they both explain breathing methods in plants and animals such as humans, while in question two the human nervous system is related to the perception of the environment through the senses.
