Answer:
light reaction and dark reaction.
Answer:
An identical setup but replacing the enzyme with an equal volume of water
Explanation:
When carrying out any experiment, it is important to set out a control in order to increase the reliability of the data and results.
The control minimizes the effects of variables other than the independent variable.
In the above experiment, starch has to be eliminated and replaced with water. Water does not have starch hence the digestive enzyme being tested will not have any effects making the data and results from the experimental group reliable.
Answer:
According to the ICSM (Intergovernmental Committee on Surveying and Mapping), there are five different types of maps: General Reference, Topographical, Thematic, Navigation Charts and Cadastral Maps and Plans.
Though the skeletal muscle cells are of different sizes and shapes, the main components of a skeletal muscle cell remain the same. The skeletal muscle is enveloped by a layer of connective tissue called epimysium, it protects the muscles from friction against the bones and other muscles.
The skeletal muscles are also covered by a fibrous connective tissue called endomysium that insulates each muscle fiber. Underneath the endomysium is the sarcolemma that is the cell membrane of the fibers and underneath that is the sarcoplasm that is the cytoplasm of the cell.
Each muscle fiber also comprises cylindrical organelles called myofibrils. Each muscle fiber comprises hundreds to thousands of myofibrils. The myofibrils are the bundles of myosin and actin proteins that go through the length of the muscle fiber and plays an essential role in the contraction of muscles.
The myofibrils are surrounded by a network of tubules and channels known as the sarcoplasmic reticulum, which is stored with calcium and is essential for the contraction of muscles. Each myofibril can be further dissociated into functional repeating segments known as sarcomeres.
