The waiter tears the raised part
of the straw wrapper a few inches from either end and he pulls until a piece of
the wrapper is entirely removed. The exposed part of the straw is what is then
placed in the drink, leaving the remaining wrapper for the customer to remove
himself. This will assure the customer that the waiter has not touched the straw
with bare hands. The part of the straw that has remained is called a straw
lace, or a drinking straw sleeve or a strawphylactic.
Aristotle based his classification system off of observations of animals, and used physical characteristics to divide animals into two groups
Answer:
Photosynthetic process
Explanation:
Cellulose, a tough, fibrous and water-insoluble polysaccharide in the cell walls of plants. It is the most abundant organic macromolecule on Earth and also the main component of a plants structure, conferring rigidity on the plants' cells.
Cellulose chains are arranged in microfibrils or bundles of polysaccharides arranged in fibrils which in turn make up the plant cell wall.
All plants are made up of polysaccharides, a very large sugar molecule made of hundreds or thousands of single sugar units (monosaccharide). Cellulose is composed of a long chain of at least 500 glucose molecules joined together by B-1,4- linkages.
Green plants create this simple sugar molecules (glucose) on their own through the process of photosynthesis. Photosynthesis is the chemical combination or fixation of C02 and water by the utilization of energy from the absorption of visible light. This glucose produced is a building carbohydrate that combines with other sugars to form the plant structure (as they make up part of cellulose) and store energy.
Answer:
Explanation:
chaperonins
Members of the Hsp60 family (also called chaperonins) facilitate the folding of proteins into their native conformations. Each chaperonin consists of 14 subunits of approximately 60 kilodaltons (kd) each, arranged in two stacked rings to form a “double doughnut” structure
The bear affects the ecosystem by eating plants and animals which lowers invasive species levels.
