What is an ellipse please help)
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Maybe they might use that math thing for Science.

Select the correct scientific notation form of this numeral using only 3 significant figures. 8,468 L
Answer:
8.47 x 10^3
Explanation:
So since we only want 3 sig figs we have to round our last digit up and then it is 10^3 because we moved the decimal place to the left 3 times to get 8.47
Comment if you have any other sig fig questions, happy to answer them!

How are some mutations similar? Provide examples.
Answer:
Mutations can be caused by high-energy sources such as radiation or by chemicals in the environment. They can also appear spontaneously during the replication of DNA. Mutations generally fall into two types: point mutations and chromosomal aberrations. In point mutations, one base pair is changed. A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious.

Explanation:
Which surface is most likely to create an echo?
a room with hard, flat walls
a room with hard, bumpy walls
a room covered in soft, wavy curtains
a room padded with soft, flat cushions
A room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.
What is echo?Echo is defined as a recurrence of sound caused by sound waves being reflected off of a wall, mountain, or other obstruction. Bats, dolphins, and fishermen all use echoes to find objects or obstructions. To find an obstruction, they are also utilized in SONAR (Sound navigation and ranging) and RADAR (Radio detection and ranging).
Buildings made of glass, metal, and concrete, the brick and metal interior of a warehouse, marble floors and buildings, or, if the room is designed in such a way that the acoustics produce an echo, plastered and painted interior walls, are examples of man-made materials that are smooth enough to produce an echo.
Thus, a room with hard, flat walls surface is most likely to create an echo. Hence option A is correct.

The process of determining relative age is called ____________.
Group of answer choices
relative dating
absolute dating
exact dating
rock
Answer:
-- I can't be too sure, but... --
Relative dating
Explanation:
Determination of the absolute age of rocks and minerals using certain radioactive isotopes.
Relative Age: The age of a rock layer compared to other layers. It can be determined by looking at the position of the rock layers.
Relative Dating: Rocks and structures are placed in order from the age of older to younger.
These two seem to be from the same section and they connect as well, so I believe "Relative Dating" is your answer but I could be wrong nevertheless I hope this helps you!

What is an alloy? Why do jewelers use alloys in jewelry?
Answer: Jewelers add different metals to strengthen the material and improve durability during wear. The resulting mix of two or more metal elements is called an alloy. For instance, pure silver bends and scratches quite easily. A metal alloy for jewelry, like sterling silver, is a better solution for most applications.
Answer:
I hope its correct! here is what I found.
An alloy is a mixture of two or more elements, at least one of which is a metal. Alloys are created to give the resulting material improved properties such as increased strength, improved corrosion resistance, or improved electrical conductivity.
Jewelers use alloys in jewelry for several reasons. One is that many pure metals are too soft to be used in jewelry, so alloys can be used to increase the strength of the metal. Additionally, many pure metals are not suitable for jewelry because they are too expensive or too difficult to work with. For example, gold is too soft in its pure form, so jewelers will often alloy it with other metals like copper and silver to make it stronger and more suitable for use in jewelry. Alloys can also be used to change the color of the metal. For example, by alloying gold with copper, jewelers can create rose gold.

What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
