Answers

Answer:

Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.

atoms

An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

What are the 8 states of matter?

Bose–Einstein condensate.

Fermionic condensate.

Degenerate matter.

Quantum Hall.

Rydberg matter.

Rydberg polaron.

Strange matter.

Superfluid

Answer:

1. Liquid, Solid, Gas

2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.

3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.

4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.

B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point

5. Ionic charges are stronger.

Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.

Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.

Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

What aspect of a muscle cell allows
movement in the body?
A. its shape is short and blunt
B. fibers within the cell move back and forth allowing the
cell to stretch and shrink
C. there are no organelles which allows it to move easier

Answers

B is the answer

muscle cells are usually long and have many fibers that can contract and relax.

I'm 100% sure about my answer because I just learned about it :)

The aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.

What is muscle cell?

Muscle cell is defined as a unique animal cell that can shrink in size by utilizing a number of motor proteins that have been strategically placed inside the cell.

The cells that make up muscle tissue have the unique capacity to shorten or contract to cause movement of the bodily components.

There are three types of muscle cells.

Cardiac muscleSmooth muscleSkeletal muscle

Protein filaments found in muscle cells slide across one another to create muscular contraction.

The configuration of these filaments gives skeletal and cardiac muscle their banded look.

They have a large number of mature mitochondria that supply the energy for muscular contraction.

Thus, the aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.

Tell the story of the predator/prey loop.
If the owl population goes up, then ...


Answers

Answer:

Below : )

Explanation:

Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.

In this scenario, if the owl is the predator, as the population rises, its prey will decrease.

If the owl is the prey, the predators would most likely increase.

Insects are smart, extracting sap from plants, biting plant parts, burrowing into fruits, twigs, and leaves, attacking roots, barks, and blooms, among other things. Larvae, adults, and nymphs are the stages of insect pests that cause harm.

Frank was driving home after a long day at work. It was late and he was having problems driving in the dark with so
much traffic. He was forced to take a detour and felt tired, so he took another sip of soda. "What would I do without
sugar and caffeine?" he mumbled to himself. Frank realized that he should probably stop the car as he noticed his hands
begin to shake, but he continued anyway. Rounding a corner, he realized that he was having trouble focusing on the
road. He tried to blink away the blurriness and shook his head, but things did not change. In an instant, the car slipped
off the road and hit a tree. "What was that?" exclaimed Frank to the night air. He quickly got out of the car and checked
himself out. Other than the shock of the accident, Frank seemed to be okay. He pulled out his cell phone and called his
wife, Stacey, to come pick him up. He then called to report the accident to the police and his insurance agent. His wife
arrived about an hour later and looked very concerned when she saw Frank sitting in the police car. "Why aren't you
going to the hospital?" screamed Stacey. "Were you drinking again?" "I'm fine, and no I wasn't drinking. Check with
Sergeant Eversman if you do not believe me. I lost focus; it has been a long day and my vision is a little off. This is too
