Answer:
a solid in which state of matter are particles packed tightly together in fixed positions.
Explanation:
hope this helps
The state of matter in which particles are arranged in either a crystalline or an amorphous form is solid. In solid state, particles are closely packed with stronger intermolecular forces.
What are solids?There are three states for matter namely solids, liquid and gas. In solid state, particles are closely packed and have strong intermolecular force. In liquid state, particles have small space to move apart and they are free to flow.
In gaseous state particles are far apart with least intermolecular forces and they are free to move everywhere. There are are two types of solids namely crystalline and amorphous solids.
Crystalline solids have perfect ordered structure with definite composition and sharp edges. Amorphous solids have disordered structure with isotropic features.

Animals respond to threats in their environment by attacking or escaping is the result of interactions between the nervous system and the muscular system.
What is nervous system?The nervous system is the largest controlling, intercommunicating and regulative system in the body.
Animals respond to threats in their environment by two ways-
They attack to the threats.They escape from the threats.Either response is the result, mostly, of interactions between the nervous system and the muscular system. This system includes all the muscles in the body and nerves.
The nervous system is the connection between the thoughts of brains to the different parts of the body to take the necessary action.

the color of a mineral is powdered form
a. luster
b.streak
c.hardness
science i need help please
Answer: Streak
Explanation: The color of a mineral in powdered form is called the mineral's streak. To find a mineral's streak, the mineral is rubbed against a piece of unglazed porcelain called a streak plate. The mark left on the streak plate is the streak.
The streak of a mineral is its powder's color, because streak does not vary, it is a more dependable quality than color. Minerals of the same color may have a streak of a different hue, hence option B is correct.
The streak of a mineral refers to the color of the material when it is in powdered form. A streak plate is an unglazed piece of porcelain that is used to locate a mineral's streak. The streak is the mark that was left on the streak plate.
When minerals are powdered, they often take on a distinct hue than when they are in crystal or massive form. It might be a completely different tint or a completely different color.

NEED HELP! ASAP! analyze and state the relationship between the independent and dependent variable by describing how the dependent variable reacted to the change in the independent variable. If you used a control, you shoukd compare the data to the control.
Answer: Depends on the experiment.
Explanation:
For any experiment, the fact remains that the independent variable always affects the measurement of the dependent variable. The independent variable is the factor in the experiment that you are changing. The dependent variable is, more often than not, the result of the change. Compare the relation between the two sets of data - probably graph it if it helps. The control data is the set of data gathered from the experiment where all the factors are not changed and are standardized. This is, in essence, the "original" data. Compare the changed data to this data. Hope it helped!
Which produces more energy, aerobic respiration or fermentation
Answer:
Aerobic Respiration.
Explanation:
Aerobic respiration refers to the metabolic pathways by which organisms break down glucose to produce ATP. ... Fermentation produces relatively less energy than respiration, because fermentation does not result in the complete oxidation of glucose.
A closed container in lab contains a sample of oxygen gas. When the temperature in lab is 16.3 degrees Celcius, the pressure in the container is 9.30 atm. What would the temperature in lab be (in Celcius) if the pressure in the container was 17.7 atm? Assume the mol and volume of the container are constant. Record your answer as a number with the correct significant figures.
Answer:
T₂ = 550.60 K
Explanation:
Given data:
Initial temperature = 16.3°C (16.3+273 = 289.3 K)
Initial pressure = 9.30 atm
Final temperature = ?
Final pressure = 17.7 atm
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
9.30 atm / 289.3 K = 17.7 atm/T₂
T₂ = 17.7 atm × 289.3 K / 9.30 atm
T₂ = 5120.61 atm. K /9.30 atm
T₂ = 550.60 K

Which seismic waves are call “push/pull” because they compress and extend as theymove through the earth? *
Which type of seismic wave can move through solid layers of the earth but not through the liquid outer core? *
Which seismic wave is the first to reach a seismic station, and therefore is the fastest? *
Answer:
1.A 2.P waves are the fastest kind of seismic wave. a longitudinal P wave has the ability to move through solid rock and fluid rock, like water or the semi-liquid layers of the earth. It pushes and pulls the rock it moves through in the same way sound waves push and pull the air. 3.The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium. It is this property of S waves that led seismologists to conclude that the Earth’s outer core is a liquid. 4.P Waves The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.Explanation:

Answer:
2 electrons
Explanation:
If you look at the periodic table, you will see that oxygen is in group 16. If you subtract 10 from 16, you will get 6 electrons, which means oxygen has 6 valence electrons. In order to become stable, you need 8 electrons. So add 2.

Is mass conserved when 40 g of sodium hydroxide undergoes a chemical change during an interaction with 36.5 g of hydrogen chloride? Use complete sentences to support your answer by explaining how this can be demonstrated.
Answer:
Explanation:According to the law of conservation of mass (mass remains the same throughout a reaction), mass is conserved in this case. This can be proven by comparing the weight of two enclosed glass containers of the reaction. They will most likely have the same weight because the products the chemical reaction creates would most likely produce a gas that can be trapped if there is no opening in the glass container. To further investigate, compare the weights of the products of the reaction with an enclosed container to another container with no lid of the same reaction.

Suppose water, carbon dioxide, and nitrogen were not recycled. What effects might this have on life on Earth?
Answer:
Sorry if this is long-
Explanation:
If water wasn't isn't recycled then all living things will eventually die out, everything on this earth that's alive needs water to live. removing water from the whole earth will kill all life and remove the most important greenhouse gas from the atmosphere.
If carbon dioxide wasn't recycled it will be removed from the atmosphere. and all the plants will die due to the lack of carbon dioxide. however, if you JUST remove carbon dioxide, plants and all animals will die due to the collapse of the food web, but there's a chance that certain species of bacteria will still live. you are also removing another green house gas from the atmosphere.
Without these green house gasses regulating the earths temperature. the earth may go into a deep freeze.
Nitrogen is an important component in amino acids. Organisms use amino acids to build proteins from dna. all living organisms use proteins for just about everything, from digestion to DNA replication. if we deplete our nitrogen, no organism on the earth can create proteins. which means, no organism can exist. Also the 4 bases of dna (adenine, guanine, cytosine, and thyamine) are nitrogen based. Without nitrogen you can't have DNA.

How are reactivity patterns on the periodic table related to an element's use in everyday applications?
Answer:
•The position of the electron in the atom can be explained by the presence of a concentric shell around the nucleus. The number of electrons in the outer shell of an atom determines its reactivity. Rare gases are less reactive because they have a completely electron shell.
