Explanation:
In the analogy of a cell as a school, lysosomes could be thought of as a teacher.
Because teacher helps students by solving complex problems in simple way and as teacher lysosomes also helps us by breaking down the complex thing in the cell.
The right answer is D) a structure made of two or more tissues functioning together for a common purpose.
An organ is a set of specific tissues capable of performing one or more specific functions. The human body has 78 organs and these organs can be grouped into systems (there are 11 of them) to perform more complex functions. For example, the bronchi and lungs are organs that belong to the respiratory system. Organs are necessary to live in good health and some organs are essential. These are the brain, heart, lungs, kidneys, liver and pancreas.
Answer:
the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.
Explanation:
Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.
Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.
