Explanation:
As thermal energy is added to a substance, which of the following changes can be predicted?
O
Spacing between particles will decrease
Vibration of individual particles will increase
Temperature of the substance will decrease
The pressure of the air around the substance will increase
Answer:
Vibration of individual particle will increase
Explanation:
This is due to the fact that whenever any substance of matter is increased in temperature, the atoms begins to move away from each other. Take for instance an ice cube for example, when an ice cube (a solid) is heated it becomes water, (a liquid). Proving that when a substance is heated, no matter the density of the material, the individual particles, or atoms, begins to spread apart.
Most of the matter in space is in a fourth state of matter called _____, which is high-energy matter consisting of positively and negatively charged particles.
A. plasma

Because molecules will move from one side to another to come to an equilibrium, or balance of concentration, the _________________________moves from side B to side A, so the water level on side A goes _____________________________.
Answer:
Water, up
Explanation:
In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.
Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.
What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol
Answer:
The correct answers are described in the Explanation section.
Explanation:
The function of the structures in the cell membrane are as follows:
a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.
b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.
c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.
d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.
e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.

Demand of oxygen in water does not increase with increase in
a/concentration of solid waste
b/number of aquatic plants
c/number of aquatic animals
d/rapid flow of water
Answer:
b. number of aquatic plants
Explanation:
The number of aquatic plants doesn't increase the demand for oxygen in water because these plants take in carbon dioxide rather than oxygen. This means that an increase in their number will not trigger an increase demand for oxygen, rather it will trigger an increase demand for carbon dioxide in its dissolved form.
An increase in the concentration of solid waste, increases the demand for oxygen because it is needed for decomposition.
An increase in aquatic animals will increase the demand for oxygen in its dissolved form because aquatic animals take in oxygen to survive.
An increase in the flow of water increases the demand for oxygen because as water flows, it mixes with air. The more rapid it is, the higher the chance to mix with oxygen.

Nitrogen is required for protein formation. What is responsible for the bulk of nitrogen fixation?
A.
air
B.
animals
C.
bacteria
D.
lightning
Answer:
The factor with the responsibility for nitrogen fixation is bacteria (option C).
Explanation:
The nitrogen that contributes to the formation of proteins comes from plants. Due to the inorganic nature of nitrogen, plants require bacteria to contribute to the assimilation of this element, a process called biological nitrogen fixation.
Nitrogen fixing bacteria in plants are called diazotroph and, in some cases, establish a symbiosis with the plant's roots, the rhizobia.
The other options, air, animals and lightning, do not correspond to biological nitrogen fixers with the ability to incorporate nitrogen into plants.ASSAP PLZ HELP 1) How do scientist typically grow bacteria in a lab? What is this large box made of? [1pt]

Describe the organism (physical appearance, habitat, function, history, etc.). Draw or find a graphic that represents your organism. Detail the organism's method of reproduction: asexual or sexual type of gametes method of fertilization advantages and disadvantages of the reproduction type Note: your description and detail of the organisms should be at least 300 words.
Explanation:
In males, the penis comes out of the cloaca into the female cloaca when mating. ... To finish off, turtle mating, if the female's egg is fertilized, results in, with some exceptions of course, the female laying an average of a 100 to 200 eggs.
All turtles lay their eggs on land, and none show parental care. Amidst this apparent uniformity, however, there is a variety of reproductive behaviours, ecologies, and physiologies.
The age at which turtles first reproduce varies from only a few years to perhaps as many as 50, with small species typically reaching sexual maturity sooner. Female false map turtles (Graptemys pseudogeographica) of the central United States, for example, are about 8 cm (3.2 inches) long and become sexually mature at two to three years.

Fossil fuels, such as coal and oil, get their names because they form from fossilized organisms trapped under extreme
pressure and heat from the center of Earth. Explain how the model shows the requirements for fossil fuel formation.
Answer:
matter into oil. (Another word for this kind of oil is petroleum.) Given enough pressure, organic matter can also become natural gas. Heat and pressure are the two main forces that transform organic matter into fossil fuels.
Explanation:
Petroleum is used to make gasoline, an important product in our everyday lives. It is also processed and part of thousands of different items, including tires, refrigerators, life jackets, and anesthetics.
The geological conditions that would eventually create petroleum formed millions of years ago, when plants, algae, and plankton drifted in oceans and shallow seas. These organisms sank to the seafloor at the end of their life cycle. Over time, they were buried and crushed under millions of tons of sediment and even more layers of plant debris. With more heat, time, and pressure, the kerogen underwent a process called catagenesis, and transformed into hydrocarbons. Hydrocarbons are simply chemicals made up of hydrogen and carbon. Different combinations of heat and pressure can create different forms of hydrocarbons. Some other examples are coal, peat, and natural gas.
Oil comes in the category of petroleum and matter into the oil. Given enough pressure, organic matter can also become natural gas. Heat and pressure are the two main forces that transform organic matter into fossil fuels.
What is fossil fuels?A fossil fuel has been hydrogen containing material found naturally in the earth's crust from the remaining portion of dead plants and animals that has to be extracted and burned as a fuel.
Fossil are natural source of energy, it has been made from decomposition of the plants and animals. Fossil fuels has been found in earth's crust and contains carbon and hydrogen which could gives energy while burning. Natural gas usually found in pockets above oil deposits. It has also found where natural oil has to be found.
Coal, oil and natural gas are best examples of fossil fuels. Coal has a material usually found in sedimentary rock deposits where rock and plants has to be buried from long time. Oil has originally found as a solid material between layers of sedimentary rocks, like shale. This material has heated and converted into a gasoline.
Therefore, Oil comes in the category of petroleum and matter into the oil. Given enough pressure, organic matter can also become natural gas. Heat and pressure are the two main forces that transform organic matter into fossil fuels.

What characteristic of water helps in regulating cell temperature and maintaining homeostasis?
Someone please help i need a claim, evidence, then a reasoning !
Answer:
The characteristic of water that helps regulate the temperature of the cells and maintain homeostasis is specific heat (Claim).
Explanation:
Specific heat is a physical property that is defined as the amount of heat needed to raise one gram of a substance by one degree Celsius. In the case of water, its specific heat is higher than that of other substances, being its value 4.186 joules/gram °C, or also 1 calorie/gram °C.
- Claim: The property of water that allows cells to regulate temperature and maintain homeostasis is specific heat.
- Evidence: a high specific heat value of water means that in bodies that possess this molecule in large quantities it is more difficult to raise the temperature
- Reasoning: Living beings are formed mostly by a high percentage of water, much of it in the intracellular compartment. The specific high heat of the water makes it difficult to have sudden changes in the internal temperature, even when the environmental temperature is high, which is a property of water that allows thermoregulation and maintains the balance or homeostasis.
2. List the inputs and outputs of
photosynthesis. What part(s) of
the plant are responsible for
taking in each of the inputs?
Answer:
Inputs: carbon dioxide (CO2) and water (H2O)
Output: Sugar (C6H12O6) and oxygen
- Roots take in water
- Leaves take in carbondioxide
Explanation:
Photosynthesis is a unique metabolic process undergone by only set of organisms called AUTOTROPHS. Autotrophs are capable of synthesizing their own food by capturing light energy (from sun) and using it to make food (sugars).
This photosynthetic process requires certain substances called INPUTS, which are basically carbon dioxide (CO2) and water (H2O) and give out products called OUTPUTS, which are sugars and oxygen gas.
- The CO2 input is taken in by the plant via the stomata on its leaves while the water (H2O) is absorbed by the roots of the plant.
