<span>The skeletal system in the body provides the shape, supports and protects organs and the soft areas of the body. Its also provides movement, produces blood for the body, and stores minerals that a human needs. So it is not only to provide the body with framework. It is much more.
</span>Hope this helps.
Answer is B) 1, 3, 2
Fish with craniums naturally preceded the evolution of sharks, since sharks have craniums. Sharks must have evolved from a cranium-wielding ancestor.
Sharks evolved about 450 million years ago, before land vertebrates (animals with spines and skeletal systems) even existed. Mammals evolved about 100 million years later.
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.
Answer A:
The process of <u><em>photosynthesis</em></u> is occurring in image A.
Photosynthesis can be described as a process by which plants use light energy and convert water and carbon dioxide into sugar and oxygen. The sugar produced is the food for the plants. This process occurs in the leaves where chloroplasts are present. Chloroplasts trap light energy.
Answer B:
<u><em>The organelle is mitochondria. The process which occurs in the mitochondria is cellular respiration.</em></u>
Mitochondria are known as the power house of a cell. The process of cellular respiration occurs in the mitochondria. By this process, glucose and oxygen are converted into carbon dioxide and water. Energy in the form of ATP is released during this process. The energy is used normal cell functions.
