Answer:

Unicellular organisms include bacteria and some protists and fungi. Many unicellular organisms live in bodies of water and must move around to find food. Most often, they must obtain nutrients by eating other organisms. Plant-like protists, and some types of bacteria, can make their own food through photosynthesis.

Answer:

Worm, Bird, Snakes, Hawks.

Explanation:

Hope this helps in anyway,

Worm, Bird, Snakes, Hawks are the  order of how the energy flows.

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism.

Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Plants, which convert solar energy to food by photosynthesis, are the primary food source.

Because energy, in the form of heat, is lost at each step, or trophic level, chains do not normally encompass more than four or five trophic levels. People can increase the total food supply by cutting out one step in the food chain.

Therefore, Worm, Bird, Snakes, Hawks are the  order of how the energy flows.

The rate at which the minerals cooled determines the crystal size in minerals formed by lava or magma. The correct option is C.

The solution is extremely saturated with some minerals, crystals form as magma cools. The crystals are quite tiny because they did not have much time to form if the magma cooled quickly. The crystals have ample time to form and become huge if the magma cools gradually.

The rate at which the minerals cooled Crystal size in minerals formed by lava or magma is primarily determined by the rate at which the minerals cooled.

When lava or magma cools slowly, it allows crystals to grow larger. Conversely, when it cools rapidly, crystals have less time to grow and thus remain smaller.

Therefore, the correct option is C.

First,the sun transferes heat to the plants,helping them grow.Animals such as deer who would eat grass,eat plants.

Explanation:

Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.

The sun is the principal energy source for practically all ecosystems on Earth. Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The food chain provides the simplest visual representation of this energy transfer.

A new trophic level is represented by each link in the chain, and the arrows depict the flow of energy through the chain. The primary producer is always at the bottom of a food chain. Plants are the most important primary producers in terrestrial ecosystems, whereas phytoplankton is the main primary producer in marine ecosystems. In their respective habitats, each generates the majority of the nutrients and energy required to maintain the rest of the food chain.

Gross primary productivity is the collective term for all the biomass produced by primary producers. After the primary producer has utilized the energy required for respiration, what is left over is what is known as net primary productivity. This is the portion that can be ingested and passed up the food chain by the main consumers.

Therefore, the transfer of energy within the trophic levels results in energy transfer.

Answer: There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean and land surface to increase.

Explanation:

Answer:

The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.

Answer:

i dont know thats a hard one

Explanation:

Answer:

1.All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences. Single-celled organisms use cell division as their method of reproduction.

2.What happens to cells that "decide" not to divide? If the decision is to not divide, the cell goes into a quiescent, or nondividing state, called G0 (G zero).

3.Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope (Figure 1).

4.Mitosis is a process where a single cell divides into two identical daughter cells (cell division).

5.In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. This type of cell division is called binary fission.

6.If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

7.Cytokinesisis the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.

8.Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.

9.During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.

11.When Replication Errors Become Mutations. Incorrectly paired nucleotides that still remain following mismatch repair become permanent mutations after the next cell division. This is because once such mistakes are established, the cell no longer recognizes them as errors.
