Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Does the shape of molecule affect the chimecal bond?
Answers
Answer:
no shape of molecules doesn't affect the chemical bond
Answer:
There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional. That is, in ionic compounds there is no intrinsically preferred direction in which a neighbour should lie for the strength of bonding to be maximized. In contrast, in a covalently bonded compound, the atoms adopt specific locations relative to one another, as in the tetrahedral arrangement of hydrogen atoms around the central carbon atom in methane, CH4, or the angular arrangement of atoms in H2O.

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears quickly, thereby altering biogeochemical cycles.
What is a possible negative consequence of introducing the non-native earthworms to forests in the Great Lake regions?

Answers
A step in designing an experimental investigation is identifying the variables that will be controlled for all experimental groups.
The correct option to the given question is option A.
An experiment is a controlled investigation where scientists manipulate and measure specific variables. Scientists design experiments to test hypotheses and answer questions. In the design of an experiment, several steps must be followed to ensure the results are accurate and reliable.
Identifying the variables that will be controlled for all experimental groups: This is an essential step in designing an experimental investigation. Controlled variables are variables that scientists keep constant throughout the experiment so that they do not influence the dependent variable.Writing a procedure that prevents other scientists from repeating the results: Scientists usually provide a detailed description of their experimental procedures to ensure that other scientists can reproduce the results of the experiment and verify its accuracy.
Making sure that the hypothesis will be supported and not refuted: A hypothesis is a statement that scientists make that explains the relationship between the variables in an experiment. The hypothesis must be tested to determine whether it is supported or refuted.Collecting each piece of data in a different way so that there is more variety: In an experiment, data is collected to support or refute the hypothesis. Scientists should collect data in different ways to ensure that the results are reliable and accurate.

The use of energy and matter by living organisms involves chemical cycling from light energy from the sun and returning of chemicals to the cycle.
Photosynthesis is the process by which plants and algae use light energy from the sun, water (H2O), and carbon dioxide (CO2) in order to produce oxygen (O2) and energy in the form of simple carbohydrates (sugar).The overall chemical reactions in the photosynthetic process can be written as 6CO2 + 6H2O → C6H12O6 (glucose) + 6O2The biogeochemical cycles refer to the pathways by which essential compounds of living things are circulated.For example, the carbon cycle involves the exchange of carbon between biotic (organisms) and abiotic (environment) factors.During photosynthesis, plants absorb CO2 from the air to produce carbohydrates such as glucose, thereby decreasing the level of CO2 in the atmosphere.Plants in turn serve as food for herbivores.Finally, when herbivores dead, carbon-based compounds are broken down into simpler carbon compounds by decomposers (i.e. bacteria and fungi).In conclusion, the use of energy and matter by living organisms involves chemical cycling from light energy from the sun for the production of chemical energy in food to the decomposition and the returning of chemicals to the cycle.

Methionine can be abbreviated as Met.
The given RNA sequence is AUGUAACGAUGCGUCGUGGCAUCAUGCUGCGUCAGCGGCGAGUCUGACCCGUCUCUAACAGGACGGCCGGGCGUUGUCGUUGA.
We can use the codon chart to determine the amino acid sequence.
The codon chart is used to determine which amino acid is coded by a particular codon in a strand of DNA/RNA.A codon is a sequence of three nucleotides in DNA or RNA that encodes for a specific amino acid.
Each codon codes for a different amino acid.
For example, the codon AUG codes for the amino acid methionine.
To determine the amino acid sequence, we start reading the RNA strand from the start codon AUG and continue reading until we reach a stop codon (UGA, UAA, or UAG).
Then we write down the amino acid sequence for the codons we read, using the codon chart.
Here, the sequence starts with AUG, which codes for methionine.
After that, the next codon is UAA which is a stop codon, so we can stop.
The amino acid sequence is therefore Methionine. So, the answer would be Methionine (Met).

when stomata is closed what happen to plants
Answers
The closure of stomata, and tiny pores on the surface of leaves, stems, and other plant organs can have a variety of impacts on plants.
Stomata closure minimizes the interchange of gases between the plant and the environment, which is one of its key consequences. Stomata are in charge of controlling the flow of gases into and out of the plant, including oxygen, carbon dioxide, and water vapor. The interchange of these gases is impeded when stomata are closed, which may have an effect on the metabolism and general wellness of the plant.
Reduced water loss from the plant is another benefit of closing stomata. The process of transpiration, or the loss of water vapor from the plant through the stomata, also involves stomata. In times of drought or other situations where the availability of water is limited, the plant can preserve water by slowing its transpiration rate when its stomata are closed.
Overall, depending on the exact situation, closing stomata can have an impact on plants that is both favorable and unfavorable. Stomata closure can have positive and bad effects on a plant's metabolism and general health. In some situations, it can help plants preserve resources and defend themselves from environmental stressors.
