The price of cotton is very high, because it is a natural fiber that must be cultivated and then harvested in certain months of the year, which in itself is a disadvantage because it interrupts the continued production of textile merchandise.
The above generates a very strong economic impact, in addition the environmental impacts are what most concern since to keep this crop in good condition, the use of pesticides, fertilizers and other minerals is constantly used that greatly pollute rivers and lakes, affecting Biodiversity. Cotton is the largest consumer of water among agricultural products, which also generates a great depletion of this valuable water resource.
For the above reasons, the use of artificial polymers emerged as a more economical and environmentally friendly alternative, since sports garments are cheaper and more resistant, they can also be kept longer, they are also more resistant to wrinkles, moths and mold.

Answer:
Synthetic clothes are economically less expensive and lightweight compared to common traditional clothes; however, they pose difficulties for recycling
Explanation:
Polymers are compounds made of long repeating molecules, which can be classified according to their origin into natural and synthetic. Synthetic polymers include, among others, nylon (household products), polyvinyl chloride, also known as PVC (clothing), polypropylene (packaging), etc. As compared to traditional clothes made up of cotton, synthetic clothes offer significant advantages related to production costs, i.e., they can be produced in high-scale processes, and automated production is less expensive than traditional processes. However, synthetic polymers consist of long repeat chains of molecules that have very strong atomic bonds, which make difficult their degradation by decomposers (i.e., non-biodegradable in nature). The process of degradation of synthetic clothes can take up many years to break down these compounds. In addition, synthetic clothes are also pollutants because they are lost in the water when they are laundered, remaining for many years in water ecosystems.
Answer:
Alpha particles are usually produced by alpha decay which consisted of two protons and two neutrons.
They are identical to the nucleus of helium-4.
The alpha particle is represented as α or α²⁺. In addition, as it is identical to nucleus of helium, it is also represented as He²⁺.
As it only posses two protons and two neutrons but no electrons, the overall charge of alpha particle is +2.
The mass number of an element refers to the total number of neutrons and protons in the nucleus. Hence, the mass number of alpha particle would be 4
Metabolism refers to all the chemical reactions that occur within an organism to maintain life. These processes include various biochemical reactions that break down nutrients from the food we consume and convert them into energy, as well as the processes that build and repair tissues, store energy, and eliminate waste products.
The thyroid gland is the endocrine system gland that produces two hormones that significantly affect metabolism. These hormones are thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in regulating the body's metabolism, which includes processes like energy production, temperature regulation, and the maintenance of healthy body weight. An imbalance in these thyroid hormones can lead to metabolic disorders such as hypothyroidism and hyperthyroidism.
B. Gautama, founder of Buddhism, was a common fisherman.
C. Buddhism remains a dominant religion in present-day India.
D. In India, Buddhists accepted the Hindu caste system
Osteocytes have important functions in the skeleton. Bone is a dynamic tissue that is constantly being reshaped by osteoblasts, which produce and secrete matrix proteins and transport mineral into the matrix, and osteoclasts, which break down the tissue.
