Describe the difference between ionic and molecular compounds.
Answers
Answer:
The main difference between Ionic and Molecular Compounds is that the electrons of atoms in ionic compounds are transferred between the elements because of the presence of a difference in electronegativity. However, in the case of molecular compounds, the electrons are only shared but not transferred.

Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

What evidence have you discovered to explain how cells are organized in the body, similar to the way dots in pointillism art is organized.
Answers
Answer:
I'd have to say that cells are grouped by function and specialty. Many of the same type of cell are joined in a common task. Muscle cells are joined to form a specific task. Different cells in the body form into different organs and structures to form the whole body.
In art, pointillism uses dots of various sizes and colors. These dots are arranged so as to produce a specific visual effect. The entire work is composed of many individual points to form the whole picture.
In this way, we can equate the body's various cell to dots in a work of pointillism.

Explain the three parts of the cell theory in your own words.
please & TYSM!!!
Answers
Answer:
Explanation:
The cell theory basically just tells you what cells are and why they exist.
There are three main parts and those are;
1;All living things are made up of cells.
This basically means that every living thing in the world has a cell . If they don't have a cell ,then they are not living.
2; New cells are created by old cells and they divide into two
This means that when when old cells start to decay new cells start to form and replicate by splitting into two cells.
3.Cell are the basic unit for life.
This means that without cells we can't live. Life started with one single cell.

Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
Answers
The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.
Buried rocks melt deep within the mantle.
