Answer:

Energy enters a community when plants and algae trap light energy during photosynthesis. They change the light energy into chemical energy in glucose, which then moves through the community as different organisms eat each other. Some energy is stored through fossilisation, while most of it is lost through heat dissipating into the environment.

Explanation:

Answer:Sample Response

The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

Answer:

Aluminium

Explanation:

Aluminium is a conductor of electricity and heat

The following materials would allow the flow of electricity: the aluminum that is present in Option C, as the aluminum is a good conductor of electricity, while the rubber and plastic are not good conductors.

Good conductors of electricity are metals such as gold, silver, aluminum, and so on, and electricity can easily pass through them, whereas non-metals are not good conductors of electricity, such as rubber, plastic, and cotton, which are not metals. The electricity can easily pass through a salt solution, and when a person touches the water while working with the electricity, they get shocked.

Hence, the following materials would allow the flow of electricity: the aluminum that is present in Option C, as the aluminum is a good conductor of electricity, while the rubber and plastic are not good conductors.

with the process of osmosis

Explanation:

It is the process of moving the water through the cell membrane when the concentration of water with the two sides of the membrane is different.

The water moves from the place with the less concentration of solute to the place with more solute, as to say from hypotonic to hypertonic place.

It is passive transport.

Biome Impact on food production

Temperate forest is the best biome for farming, and most of the temperate forest consists of farms or human habitats

Explanation:

Explanation: Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. In nature, crystals can form when liquid rock, called magma, cools.

Answer : It formed in magma that cooled very slowly.

Answer:

The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time. Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane.

Answer:

The digestive system helps break down complex meals into the constituent parts the body can use: carbohydrates, proteins, fats, vitamins and minerals.

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

Answer:

Explanation:

This question is a practical question and would require some sort of experiment. However, let's define what rate of reaction means. The rate of a chemical reaction (in this case fermentation) can be described as the speed at which the reaction occurs; meaning the speed at which product is formed per unit time.

The "claim" in the attachment in the question can be referred to as hypothesis since this question is an experiment. The null hypothesis here will be "the rate of alcoholic fermentation is not affected by the type of sugar used as an energy source".

The "evidence" from the attachment will be result of the experiment conducted which cannot be provided here.

However, the conclusion of this experiment (which also answers the main question; does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy?) should show that the rate of alcoholic fermentation should differ based on the type of sugar used. This is because different enzymes are responsible for the conversion of this disaccharide to the glucose monosaccharide which is what finally undergoes alcoholic fermentation. For example sucrose is broken down into glucose and fructose by sucrase while lactose is broken down into glucose and galactose by the enzyme lactase.

Note that the reaction rate from glucose to produce CO₂ (a product of fermentation) will be the same (regardless of source) but the reaction time from the disaccharide to glucose will be different because of the difference in enzyme and can also be determined by comparing the time to produce the CO₂ by the sugars and the time to produce same amount of CO₂ when given water in the experiment .

Answer: for HCO it dissolves in water

for CH2OH IT dissolves in water

Explanation:

i just took the test

It depends on the particular substance concerned that one can predict whether it will dissolve in water or not. Listed below are some general principles:

Things that usually dissolve in water include:

1. Ionic Compounds: Many salts, including sodium chloride (table salt), dissolve in water because of the attraction between positive and negative ions and polar water molecules.

2. Polar Compounds: Due to the similar polarity of water molecules, substances with polar molecules, such as sugar and ethanol, tend to dissolve in water.

3. Many gases Some gases, such as oxygen (O2) and carbon dioxide (CO2), can partially dissolve in water.

Things that usually don't dissolve in water include:

1. Oils, greases, and hydrocarbons are examples of non-polar substances that do not dissolve in water because water is a polar solvent and does not interact significantly with non-polar substances.

2. Insoluble salts: Some salts, such as lead(II) sulfide (PbS) and silver chloride (AgCl), have low solubility in water.

Answer:

The high specific heat of water caused by hydrogen bonding

Explanation:

Specific heat capacity of a substance is the quantity of heat required to raise the temperature of a unit mass of that substance by one degree Celsius (1° C).

Due to the hydrogen bonding present in water, water has a high specific heat capacity of 4184 Joules per kilogram. This means that, water has to absorb 4,184 Joules of heat for the temperature of one kilogram of water to increase 1°C. When compared to other substances such as metals, this is very high. For example, the specific heat capacity of copper is 385  Joules per kilogram which means that it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.

Therefore water, can absorb a large quantity of heat with very little changes in its temperature. This property of water helps the oceans and seas to serve as heat reservoirs by absorbing a large quantity of heat in hotter seasons and releasing these heat in colder seasons.

Answer:

Violet plant with small leaves found in sunny places while violet plant with big leaves are found in the shade.

Explanation:

In our planet, the plants though they cannot move like animals and humans, they can adapt themselves to the surroundings and the environment. Plants have the ability to adjust themselves in the varied climate and landscape around themselves.

Almost all the plants need sun light or sun energy to grow and make their own food. Some plants grow well in direct sun light  while some others grow in shades.

In the context, scientist discovered two varieties of violet plants out of which one grows frequently in the sunny places whereas the other found frequently in the shade.

Now the violet plant which have small leaves than the other violet plant are found more frequently in the sunny places as these plants get direct sun light or energy all through the day to make their food. While the plant which have adapted to make food in the shade having large leafs so they can absorb more of sun's energy and make their food. They are found in the shade.

11.osmosis

12.ATP

Explanation:

Active transport is similar to osmosis but it happens with other substances

The phospholipid is shaped like a ball with two legs coming out and the legs connect on both sides of the cell to help protect the membrane and to help provide pathways.

Facilitated diffusion is just what is happening when the material or substance is going through the membrane which is either active or passive.

Osmosis is when the water passes through the membrane from a less concentrated place to a high concentrated place

ATP is energy used to help material or substance through the cell however only certain types of material need the energy to pass through some don't require energy at all

Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.

Explanation:

The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.

The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.

MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.

The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.

The cellular process that enables cells to grow and develop into tissues is mitosis.

Mitosis allows a single cell to divide and form two morphologically and genetically identical cells. The two cells each also have the potential to divide if the conditions are right.

Thus, a single cell has the capacity to become tens, hundreds, or even thousands of cells as a result of mitotic division.

A tissue is formed from a group of cells that have differentiated to perform similar functions. In order words, without mitosis, there is absolutely no chance for tissues to be formed.
