Explanation:
Hey,
so here the student is saying that the given mass is of one atom. But when we usually talk about amu it is the unified atomic mass so mass of all the atoms present.
So that's why he is wrong.
Also the definitions states,
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
Answer:
See below.
Explanation:
121.76 amu is the Relative Atomic Mass of Antimony (the average mass of the different isotopes). . The element exists as a mixture of isotopes , the main one being SB121 which has a mass of 121.

In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
Hope This Helps! Have A Nice Day!
Final answer:
The human body is a system of interacting subsystems composed of specialized cells and tissues, each performing a specific function. These subsystems, such as the circulatory and digestive systems, cooperate to maintain overall health and homeostasis.
Explanation:
The body is a system of interacting subsystems composed of a group of specialized cells and tissues. This is because each subsystem or organ system consists of particular types of cells and tissues that carry out specific functions. For instance, the circulatory system, made up of the heart, blood vessels, and blood cells, transports nutrients and oxygen throughout the body. The digestive system, including the stomach, small and large intestines, and other components, breaks down food and absorbs nutrients. These subsystems interact with each other to maintain the body's overall homeostasis and good health.

The standard units of measurement are particularly important to scientists because they make the result more accurate and precise.
What are accuracy and precision?
When the average value of the different measurements is similar to the correct value then the measurement is said to be accurate and the phenomenon is said to be accurate.
When the values of measurement are close to each other then the result is said to be precise and the phenomena are said to be precise and need to do for the better accuracy of results.
Therefore, they make the result more accurate and precise.The standard units of measurement are particularly important to scientists.

B. evaporate deposition
C. chemical precipitation
D. Biological precipitation
Answers
The answer is: D. Biological precipitation.
Biological precipitation is the deposition of minerals from solution by the agency of organisms.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass.
Ocean sediments originate from numerous sources:
1) biological activity (biogenous).
2) weathering and erosion of the continents (terrigenous/lithogenous).
3) volcanic eruptions (volcanogenous).
4) chemical processes (hydrogenous).

The Correct answer is CH3COOH
The explanation:
when the electrolyte is: A substance that dissociates into ions in solution and acquires the capacity to conduct electricity.
- Electrolyte is actually a compound that dissolves easily in water and creates a solution that becomes a good conductor of electricity.
- The existence of free ions is the reason why the solution becomes a good conductor of electricity.
-The compounds that release small number of free ions on dissolving in water are called weak electrolytes
-and those that release large number of ions are strong electrolyte.
acetic acid partially dissociates in water to form two ions, H+ and CH3COO- , therefore making it a weak electrolyte
