Answer:
true
Explanation:
Carbohydrates, like all organic molecules, always contain carbon (C) and hydrogen (H) atoms. Carbohydrate molecules are characterized by the presence of the atomic grouping H-C-OH, in which the ratio of hydrogen atoms (H) to oxygen atoms (O) is approximately 2:1. Because this ratio is the same as the ratio in water, the name “hydrates of carbon” seems appropriate. Carbohydrates first and foremost function for quick, short-term energy storage in all organisms, including humans.

They cool too quickly to form crystal.
The correct answer is: the mother cell is diploid, but the products of the first division are haploid.
Meiosis is cell division with the purpose to produce the gametes: sperm and eggs. Meiosis is a two-step division process:
• meiosis I- Homologues pairs (chromosome pairs an organism receives from parents, one from mother, one from father) separate during this phase
• meiosis II – Separation of sister chromatids.
Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.
