What are Decomposers?Decomposers are defined as organisms that break down dead or decaying organisms that undergo decomposition, a process possible only by certain kingdoms such as fungi and bacteria.
These decomposers recycle and convert the dead matter into humus which mixes with forest soil and provides necessary nutrients to plants. Some examples of decomposers are fungi, bacteria and detritivores, invertebrates, such as earthworms and termites.
Thus, Fungi and bacteria are most helpful in preventing Earth from being covered with the bodies of dead organisms. So, the correct option is D.

Gabrielle and her friend William had nine identical long, rectangular containers. Gabrielle added water to the containers, filling three to a depth of one-half inch, three to a depth of one inch, and three to a depth of two inches. She lifted the end of one container to a height of three inches, let the water settle, and then quickly set the container back down. This motion created a wave. Using a stopwatch, William timed how long it took the wave to travel across the container and back one time. Gabrielle and William repeated this process with all nine containers. Identity the question that Gabrielle and William's experiment can best answer. Are the heights of waves in containers affected by the depth of water in the containers? Does container shape affect the amount of time it takes waves to travel through water in containers? Does water depth affect the amount of time it takes waves to travel through water in containers?

A cell that consists of a 65% salt concentration is placed in a solution with a 27% salt concentration. What will happen to this cell?
Answers
Answer:
The correct answer would be - the cell will get water and expand.
Explanation:
If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.
Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.

Meiosis does PMAT twice! That means there is a prophase I and a prophase II. There is a metaphase I and a metaphase II. Etc… If the cartoon below has chromosomes in the middle of the cell, how would you know whether it was in metaphase I or metaphase II?
Answers
One can detect if the cell is in metaphase I or II as follows:
If there is homologous chromosomes (metaphase I) or duplicated chromosomes/sister chromatids (metaphase II) in the middle of the cell.
MEIOSIS:Meiosis involves two series of nuclear divisions grouped into meiosis I and meiosis II. Each division has the same number of stages i.e prophase, metaphase, anaphase, telophase etc.Meiosis I involves the separation of homologous chromosomes i.e similar but non-identical chromosomes from each parent. On the other hand, meiosis II involves the separation of sister chromatids (duplicated chromosome). Since metaphase is generally characterized by the alignment of chromosome at the middle of the cell, it means that the difference between metaphase in meiosis I and II will be whether it is homologous chromosomes that are in the middle or sister chromatids.Therefore, according to this question, one would know if the cartoon is in metaphase I or II if:
- there are homologous chromosomes in the middle of the cell (metaphase I)
- there are sister chromatids in the middle of the cell (metaphase II).

Answer:
Electron transport chain
This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP. One molecule of ATP (or an equivalent) is produced per each turn of the cycle.

How is the opening and closing of stomata controlled? Besides water, describe two other factors that might influence a plant's regulation
of stomata opening and closing.
es 01)
Type your answer below:
Answers
Answer:
Stomata open or close depending on the urgency of the occlusive cells that form it. If they swell because they receive water from the adjacent cells, the stoma opens, as its cell walls buckle, with which gases enter or leave through the ostiole. If on the contrary, the adjacent cells absorb the water from the occlusives and these, ultimately, lose water, they become flaccid and the stoma closes, allowing neither the exit nor the entry of gases. Other factors that influence the regulation of stomatal opening and closing are the circadian rhythm (day / night) and the concentration of CO2.
Explanation:
A stoma is basically a pore that is used for gas exchange with the environment and the transpiration of the plant. It is surrounded by two cells, called occlusive or guard cells, these have chloroplasts and have a thickening on their adjacent surfaces. Stomatal movements depend on changes in the turgor pressure of the occlusive cells and adjacent epidermal cells. Stomata open when water diffuses through osmosis into the occlusive cells from the surrounding epidermal cells. As the turgor pressure increases in the stomatal cells, it induces them to swell and the stomata open. In contrast, when the turgor pressure decreases, the occlusive cells become flaccid and the thickened walls come together, closing the pore. Other factors that influence the regulation of stomatal opening and closing are the circadian rhythm (day / night) and the concentration of CO2. Guard cells regulate the opening of stomata by integrating different signals, both endogenous and exogenous (environmental).Stomatal opening occurs when the concentration of CO2 in the occlusive cell decreases as a result of photosynthesis, while it closes when this concentration increases, even in the presence of light. The plants implement a temporary regulation of the stomata to limit water losses during the CO2 absorption process, that is, the stomata are opened during the day and closed at night to prevent unnecessary water losses, since during this period, photosynthesis does not occur and there is no demand for CO2. With the first rays of sunlight, the plant again begins to photosynthesize, again the stomata open since the demand for CO2 is high. The stomatal opening favors the transpiration of the plant.
