Cell specialization allows cells to perform essential cell specific tasks. Such as nerve cells, red blood cells etc.
Pasteur produced a nutrient broth and placed equal amounts of it in two long necked flasks. One flask had a straight neck (control) and the other had a swan shaped bent neck (being tested). He boiled the broth in both the flasks to kill any living organism that might be surviving on it. The two flasks were then left in the open air of the room to cool down. After several days passed, Pasteur noticed that the broth in the straight necked flask had changed its color but the swan necked flask didn't. From this observation he was able to conclude that the straight necked flask had let the organisms enter the flask and contaminate the broth. The swan necked flask blocked the entry of the organisms from the open air and thus remained unaffected.
Answer:
It has been suggested that these kinds of lesions may be indicative of fighting with other members of its species or the attacks of predators
Explanation:
The Neandertals were exposed to very hard environmental conditions, thereby these lesions may be indicative of such conditions to which this species was exposed.
Answer:
<h2>lactic acid</h2>
Explanation:
Glycolysis is the process of the breakdown of glucose by enzymes, and the energy production in the cell. It occurs in all cell in all organism. Through glycolysis, there is the production of ATP and NADH, which are used in energy requirement. Glycolysis occurs in cytosol, with the help of various enzymes, like hexokinase, phosphofructokinase and PEP etc. When glycolysis produces pyruvic acid faster than it can be used by the mitochondria, the pyruvic acid is converted to lactic acid.
