answer 1. The arrow is pointing to the "nucleus."
Explanation:
A cell is the smallest unit in an organism. It mainly functions to provide structure to the human body, thus it is called "the building blocks of life."
There are 6 organelles in a cell and these are Nucleus, Ribosomes, Endoplasmic Reticulum, Golgi Apparatus, Chloroplasts, and Mitochondria.
The arrow is pointing to the cell's nucleus in the image above. This is an organelle that is enclosed in a membrane. It is where you can find the deoxyribonucleic acid or the DNA, which is essential for hereditary function. It also coordinates activities in the cell, such as metabolism, synthesis of proteins, cell division.
Remember, not all cells have a nucleus. Only eukaryotic cells have a nucleus. These cells are considered more advanced.
2. An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
<u>Answer:</u> The excess reactant for the given reaction is
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is present in less amount and it limits the formation of products.
Excess reagent is defined as the reagent which is present in large amount.
For the given chemical reaction:
We are given:
Moles of calcium nitrate = 3.4 mol
Moles of lithium phosphate = 2.4 mol
By stoichiometry of the reaction:
3 moles of calcium nitrate reacts with 2 moles of lithium phosphate
So, 3.4 moles of calcium nitrate will react with = of lithium phosphate
As, the given amount of lithium phosphate is more than the required amount. So, it is considered as an excess reagent.
Thus, calcium nitrate is considered as the limiting reagent because it limits the formation of products.
Hence, the excess reactant for the given reaction is
I guess the answer <span>can be an alkali metal, alkaline earth metal, or transition metals.
Hope this helps :)

2) may either scatter light or be opaque
3) can be separated by filtration
If you're asking about the greatest amplitude of visible sunlight, then red light waves.
However if you're talking about the colors just in general, then radio waves.
