Answer:
In a solid, the molecules are tightly packed in neat rows and they vibrate quickly. Solids have a definite shape and volume. In a liquid, the molecules have more energy and they move around more freely. Liquids have a definite volume but they don't have a definite shape. The molecules in gases are spread apart and move very freely with very much energy. Gases do not have a definite shape or volume.
Hope this helps!

The description of the arrangement of water molecules and their motion in a solid, liquid and gas form and how they differ in each form is as follows:
Solid state is characterized because the molecules that compose it are very close together by a network of covalent bonds and in more or less fixed positions; this makes the distance between the particles practically unchanged.
This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.
In the liquid state, the forces between the particles are weaker than in the solid state, which allows the particles to have some freedom of rotation and translation, due to mobile ions.
Besides the vibration; they can slide over each other and maintain a constant mean distance between them without being fixed.
For this reason, liquids, unlike solids, take variable forms, depending on the container that contains them and they can also flow easily.
Their similarity to solids is based on the fact that, like the solids, they are difficult to compress and have constant volume.
In the gaseous state the attractive forces are practically zero and the particles acquire a total mobility of vibration, rotation and translation,
Being the distance between the molecules much greater than the one that they have in solid or liquid state and, in addition, variable at all times.
Gases, unlike solids and liquids, can be easily compressed or expanded and also take the shape of the container that contains them, occupying the entire available volume.
Therefore, the intensities of the interactions or cohesion forces of water molecules are not the same in solids, liquids and gases, the effects of movement and interaction on the arrangement of the particles are opposed, resulting in different states of aggregation.

Which is denser, 50 mL of water or 500 mL of water?
Answer:
50mL
Explanation:
Density is inversely proportional to volume.
This implies that, for the same mass of water, the higher the volume, the less dense it is.
By comparison 500ml is greater than 50ml
Going by the above analysis, 50ml will be less dense than 500ml because it is smaller.
A change in body temperature will have which of the following effects on enzymes in the body?
A. A temporary change in the ability of some enzymes to bind with their coenzymes
B. A temporary change in the ability of some enzymes to bind with their substrate
C. A temporary reduction in the concentration of some enzymes in the body
D. A temporary increase in the concentration of some enzymes in the body
Pls help. I think it’s either C or D idk and the question is worth a lot of points :(
Answer:
The answer is B :)
Explanation:
A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.
Thus, Animals can be categorized into two groups: those that keep a steady body temperature despite varying environmental temperatures and those that have a body temperature that fluctuates with the environment.
Ectotherms are animals that do not regulate their body temperature but instead depend on outside energy to accomplish it.
The name "cold-blooded" has been applied to this category, but it might not be appropriate for an animal living in the desert with a fairly warm body temperature. Animals known as endotherms can experience temperature extremes but rely on internal sources to maintain their body temperature.
Thus, A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.

Why did life first occur in the oceans and not on Earth’s surface?
Answer:
I think because many more bacteria and cells and etc were first like created in the water, they they developed and made bigger and bigger living organisms
Answer:
Because God decided that he was gonna make animals first and he started with the ocean and then land and sky. He then made Adam to take care of all of the animals. But saw that he was lonely and made Eve with one of his ribs. He then put them in the garden of Eden with a tree that was forbidden to eat from. The tree of knowledge of the good and evil. One day eve was walking by the tree when a serpant asked her why they didn't eat from it. She replied by saying that God asked them to not eat from that tree. The serpant told Eve that God just doesn't want them to be knowledgeable like him. She took a bite of the apple and then gave some to Adam. They then realized that they were naked and made clothing from animal skin. This was what created sin. They tried to hide from God but he already knew and he banished them from the garden with angels and a fire sword at the enterance. He went to the serpant and cursed him for telling Eve to eat from the tree. Adam and Eve went on their way and had 2 boys. Cane and Abel.

Please help! If gastric protease was put in the intestine, do you think it could still carry out its usual function of digestion? Why or why not?
Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.

A snake catches and eats a small field mouse. Later that day, a hawk catches the snake and eats it. Which three terms describe the snake? consumer, predator, prey parasite, predator, producer predator, producer, consumer prey, parasite, producer
Answer:
Consumer, predator, and prey.
Explanation:
The snake is a consumer and a predator because it eats or consumes another organism (the mouse), but it is also prey because it is consumed or preyed upon by another predator (the hawk).
The three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.
What is Predator?A predator may be characterized as a type of animal that significantly obtains food by killing and consuming other organisms in the form of food and taking energy for the metabolic processes. These animals hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey.
According to the context of this question, when a snake eats a mouse, it is called a consumer and predator because it actually drives energy from the mouse in order to facilitate its metabolic processes. When a hawk when catches a snake and eats it, it is often known as prey, and the hawk is known as a predator in this case.
Therefore, the three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.

Why is oceanic crust younger than continental crust?
Answer:What is the best explanation for why oceanic crust is subducted by continental crust?
The continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle.
Explanation:Why oceanic crust is younger than Continental?
Through mantle convection, the rich minerals of the mantle may be ultimately “recycled” as they surface as crust-making lava at mid-ocean ridges and volcanoes. Largely due to subduction, oceanic crust is much, much younger than continental crustWhy is the theory of plate tectonics so important to geologists?

You are at the zoo and watching a lion chew on some meat. You begin to taunt the lion since he is behind the glass and cannot get to you. He
charges the glass and breaks through. Your adrenaline kicks in and you take off running. What system is repressed during your escape?
Answer:
The parasympathetic nervous system is repressed during your escape.
Explanation:
In the exposed example, during your escape from the lion, the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) system are responsible for your body response. They send signals and release adrenaline and noradrenaline to increase your heart biting frequency, and blood pressure, stimulating your respiration and dilating your respiratory tracts.
Once you manage to escape from the lion, and the threat factor is over, the body gets back to normality. At this point, the parasympathetic nervous system is activated. Your body activities become normal again. Your arterial pressure, respiratory frequency, and cardiac frequency get reduced to their normal conditions. You are relaxed and at rest.
When the parasympathetic system is activated, the sympathetic nervous system is not, as they perform in opposite ways.
