what is the density to the nearest hundredths, of a metal with a volume of 3.00 cm3 and a mass of 8.13g?
The density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³. Details about density can be found below.
How to calculate density?The density of a substance is a measure of the mass of matter contained by a unit volume and it can be calculated by dividing the mass of the substance by its volume.
According to this question, a metal with a volume of 3.00 cm³ and a mass of 8.13g is given. The density of the metal can be calculated as follows:
Density = 8.13g ÷ 3cm³
Density = 2.71g/cm³
Therefore, the density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³.

Answer:
i) Rusting occurs the least in tubes 2 and 3 because either of air and water which are necessary for rusting is absent in the two tubes respectively.
ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.
Explanation:
Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.
For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.
In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.
In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.
In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.
In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.

Which phrase describes the relative age of a rock?
Answer:
Uses the law of superposition to determine which rock is older or younger.
Explanation:
Relative age refers to the age of the rock when compared to other rocks. The law of superposition was developed by Nicholas Steno. In this process, you determine which rock layer is older or younger in terms of the sequence they were laid out or layers were formed. This law states that the lower the layer, the older the rock layer is as compared to those on top of it.

Explanation:
Label the following topographic map. Click on a label below the map to select it, and then click on the appropriate box on the map to place the label. (Increments for contour lines is 50 feet).
Choices:
River Flow East
Depression
2650 feet
Sleep Area
Based on the information, it can be inferred that the concepts are organized from left to right as follows: Depression, Sleep area, River Flow East, and 2650 feet.
How to identify the correct space for each concept?To locate each concept in the correct space we must know how to read a topographic map. In this case, the depression would be the first concept because in the shaded area the contour lines are shown very close, this is generally related to a depression area in which the slope is very pronounced.
On the other hand, the sleeping area is at the top of the mountain at the bottom of the image because a flat region is shown on the top of the mountain.
Additionally, the blue line through the topographic map represents a river so this could be labeled River Flow East. Finally, the contour line that is at 2650 feet high would be the last space considering that each line represents an increase (or decrease) of 50 feet.

What word is used to describe plant cells placed in a hypotonic solution?
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

Answer:
The nucleus contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules.
The nucleus contains the instructions that tell a cell what functions to perform.
What is a nucleus?In terms of genomics, a nucleus is an organelle within a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules (such as proteins and nucleic acids) into and out of the nucleus.
The largest organelle in a eukaryotic cell, the nucleus, is thought to be the cell's command center. The majority of the cell's DNA, which makes up the chromosomes and is encoded with the genetic instructions needed to build proteins, is found in this region.
Therefore, Nearly all the cell's DNA, along with the coded instructions for constructing proteins and other significant components, is found in the nucleus.
