The musculoskeletal system provides form, support, stability, and movement to the body.</span>
Answer: a stain with no other chemicals or detergents added to it should be the control group
Explanation: A control group is defined as as an experiment or study that does NOT relieve any treatment by the researchers so the stain would not have any treatment added to it
Answer:
morphogenesis
Explanation:
The developmental process is known as morphogenesis. This process that follows a plant throughout its entire life and shows how the plant shapes itself through the development of cells, tissues, and organs throughout its life. These developments are dependent on many factors such as the genetics of the plant as well as the environmental conditions that the plant is exposed to. All of this affects the type of organs that the plant develops such as leaves, flowers, and fruits.
Answer:
I don't know what it's for
Answer:
1. The prosthetic group of hemoglobin and myoglobin is heme.
2.The organic ring component of heme is porphyrin ring.
3. Under normal conditions, the central atom of heme is Iron (Fe2+).
4. In deoxyhaemoglobin the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
5.The central iron atom has six bonds: four to nitrogen atoms in the porphyrin, one to a histidine residue and one to oxygen.
Explanation:
1. The heme is the prosthetic group common to both the hemoglobin and myoglobin. It is made up of a central iron ring.
2. The porphyrin ring is the organic component of the heme that surrounds the iron ring. Its based on a tetrapyrole ring called porphin commonly found in other biomolecules such as cytochrome and chlorophyll in plants
3. Iron (Fe2+) is central to the heme structure. It has the ability to bind to an oxygen molecule at a time. This gives the protein- hemoglobin the ability to bind to 4 oxygen molecules at a time.
4. Deoxyhaemoglobin is simply a reduced form of hemoglobin which has lost oxygen molecule in red blood cells. It is purple blue in colour.
5. In the middle of the porphyrin ring, the iron binds to 4 nitrogen atoms. 2 free binding sites are available on either side of the plane heme structure with histidine surounding the heme molecule.
