Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
The type of muscle found at the heart is the cardiac muscle tissue. This tissue has the phyical striped characteristic of a skeletal muscle tissue and works like a involuntary muscle because it works without our control
This type of tissue is packed wirh mitochondria which provides it with alot of energy. This is very crucial becaise the heart has to constantly beat
Answer:
The tree absorbs light energy from sunlight, converting the light energy into chemical potential energy stored in chemical bonds. The tree uses this energy to build leaves and branches and fruit. When the apple hits the ground, kinetic energy is transformed into heat energy.
Explanation:
Gene regulation in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription. Any step of gene expression may be modulated, from the DNA-RNA transcription step to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, the most extensively utilised point is Transcription Initiation: Chromatin domains.
Cellular respiration is the process by which glucose is broken down to carbon dioxide and water in the cell.
Cellular respiration refers to the process in which glucose is broken down to produce energy. The reaction of cellular respiration is; C6H12O6 -----> 6H20 + 6CO2. This process occurs in the mitochondria of the cell which is within the cytoplasm. In times of oxygen deficit, lactate or ethanol may be produced by the process.
The following statements are true about cellular respiration;
- the reactions happen in the cytoplasm
