Chitin is a polysaccharide made up of N - acetylglucosamine .
Fungi cell walls are made of chitin. Chitin is also the major ingredient of the exoskeletons of crustaceans and arthropods. Spiders, beetles, butterflies, lobsters, shrimps and crabs all have chitin in their protective armor.
when intermixed with protein and other pigments, it forms different levels of hardness and a variety of distinct colors. Alone, chitin appears translucent and not hard. In arthropods, it is secreted by epidermal cells.
Answer:
All carbohydrates, including sugar, contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates.
Carbon and hydrogen
Each sheep has their own genetic information. So if they were unrelated, each sheep would give unique genes, resulting in unique offspring.
Annual lambing, in which ewes born in the fall give birth to lambs in the spring, is the most popular method of breeding sheep. However, ewes are bred in late spring to lamb in fall, or in early fall or late summer to lamb in winter.
This produces lambs for more lucrative markets (eg, September for the Christmas lamb market).
In order to do this, programs that extend the ovulatory season into the late summer or stimulate estrus during the anovulatory season in the spring must be used of controlled intravaginal drug-releasing devices.
Producers who have flocks that lamb out of season, however, hardly ever follow an annual breeding plan since, generally speaking
Therefore, Each sheep has their own genetic information. So if they were unrelated, each sheep would give unique genes, resulting in unique offspring.
