Answer:
all of them.
Explanation:
biodiversity is good for any ecosystem.
Final answer:
Biodiversity is essential for all ecosystems, providing ecosystem services that include pollination, nutrient recycling, and the maintenance of soil health. It enables ecosystems to be productive and stable, ultimately supporting human life by providing food, medicinal resources, and clean water. Loss of biodiversity can lead to ecosystem degradation and threaten these vital services.
Explanation:
All ecosystems need biodiversity to maintain their health and stability. Biodiversity includes different levels such as species diversity, genetic diversity, and ecosystem diversity. High biodiversity, as seen in coral reefs and rainforests, provides numerous ecosystem services such as pollination, nutrient cycling, pest control, soil development, and maintenance. These ecosystems function effectively and support the vast array of life, including human life, by providing food sources, medicinal compounds, and clean water.
Biodiversity plays a critical role in nutrient cycling, where a variety of soil organisms contribute to nitrogen fixation and nutrient recycling. It enables plants to be pollinated and decomposers to recycle waste material. The genetic diversity within populations is crucial for their ability to adapt to changes, whether they be environmental shifts or emerging diseases.
The loss of biodiversity can lead to the degradation of these ecosystem services, making food production more expensive or even impossible, and reducing the soil productivity due to the loss of ecosystem interactions. Therefore, preserving biodiversity not only sustains our ecosystems but is vital for the long-term survival of humanity.

what characteristics of water is most helpful to fish in a lake
Answer:
D. water is able to hold dissolved oxygen
Explanation:
Dissolved oxygen (DO) can enter water by diffusing across the surface of water from the air, or as a byproduct of photosynthesis by other aquatic organisms like plants and algae. Each aquatic organism, like land-dwellers, has specific oxygen requirements. Fish use DO for the process of respiration, where they obtain oxygen from the surrounding water using their gills. Anoxic conditions, where oxygen levels are low usually result in significant deaths in fish populations.
DNA carries the instructions to make ?
Proteins.
Protein synthesis (process includes transcription and translation):
The DNA sequence is copied (transcribed) by mRNA in the nucleus then translated in ribosomes which will instruct tRNA to collect specific amino acids to bring back to the ribosome by reading 3 letters at once (called codon, and one codon codes for 1 amino acid). Those amino acids will attach to each other and when the sequence codes for stop, it stops, and a protein forms.

explain why stratospheric ozone protection has been considered an environmental success story
Answer:
Ozone gas in stratosphere is considered as an environmental success because of its protective role.
Explanation:
Ozone is both hazardous and beneficial gas depending on where it is found. On ground or troposphere it has harmful impact on the health of living organisms and can trigger asthma. On the other hand, Stratospheric ozone protects us from harmful UV radiations that are coming from the Sun. It acts as a sheath around Earth which reflects the unwanted UV radiations back in space,which otherwise would cause various diseases and skin cancer. Ozone hole is the depleted region above in the atmosphere where Ozone has vanished due to several human activities. One of those regions lie above the Antarctic.
Stratospheric ozone protection is hailed as an environmental success story due to the effectiveness of the Montreal Protocol, which led to a decrease in ozone-depleting substances like CFCs and resulted in the gradual recovery of the ozone layer. This showcases the power of global cooperation and policy in resolving environmental challenges and reducing health risks.
Explanation:Stratospheric ozone protection is considered an environmental success story because it showcases successful international cooperation in addressing a serious environmental issue. The Montreal Protocol, an international agreement signed in 1987, aimed to phase out the production and uses of ozone-depleting substances, notably chlorofluorocarbons (CFCs). This concerted effort has led to a significant reduction in emissions of CFCs and other harmful chemicals, allowing the ozone layer to begin a slow process of recovery.
The beneficial ozone layer, found in the upper atmosphere, forms a protective shield that absorbs much of the sun's harmful ultraviolet radiation. When scientists discovered that CFCs released into the atmosphere were causing the depletion of this layer, creating the infamous 'ozone hole', global action was triggered. The success is evident in the shrinking size of the ozone hole and the 20% improvement in ozone depletion since 2005. However, constant vigilance and monitoring are still needed as ongoing challenges such as illegal emissions threaten these recovery efforts.
Overall, the protection of the stratospheric ozone is an encouraging example of how global policy can reverse and potentially resolve significant environmental threats. The reduction in skin cancer risks and the positive trajectory of ozone regeneration underscore the importance of maintaining these efforts for future population health and ecological stability.

What happens in each of the two phases of photosynthesis
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
In photosynthesis, there are two stages: the light-dependent reactions and the light-independent reactions. In the light-dependent reactions, energy from sunlight is converted into chemical energy. In the light-independent reactions, this chemical energy is used to build sugar molecules from carbon dioxide.
Explanation:Photosynthesis, the vital process by which plants and certain other organisms convert light energy into chemical energy, unfolds in two distinct stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). These stages are intricately connected and serve as the foundation of energy production and carbon fixation in autotrophic organisms.
Light-Dependent Reactions:
Location: These reactions occur in the thylakoid membranes of chloroplasts.
Function: Light-dependent reactions capture and convert light energy into chemical energy, typically in the form of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH).
Process: Chlorophyll and other pigments absorb light energy, which triggers the flow of electrons through the photosystems (Photosystem II and Photosystem I). This electron transport chain pumps protons (H⁺ ions) into the thylakoid space, creating a proton gradient.
Outcome: The proton gradient drives ATP synthesis via ATP synthase. Simultaneously, electrons reduce NADP⁺ to form NADPH.
Light-Independent Reactions (Calvin Cycle):
Location: These reactions occur in the stroma of chloroplasts.
Function: Light-independent reactions utilize the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide (CO₂) into organic molecules, primarily glucose.
Process: The Calvin cycle incorporates CO₂ into a five-carbon sugar molecule called ribulose-1,5-bisphosphate (RuBP). The enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) facilitates the initial fixation of CO₂. The subsequent reduction and regeneration phases ultimately yield glucose and regenerate RuBP for continuous cycling.
Energy Carriers:
ATP and NADPH, generated during the light-dependent reactions, serve as energy carriers that transport chemical energy from the thylakoids (where light is absorbed) to the stroma (where carbon fixation occurs).
These energy-rich molecules power the conversion of CO₂ into glucose during the Calvin cycle, making them essential for the synthesis of organic compounds.

A particular fungi is the source of penicillin
The particular fungus that is the source of penicillin is of the genus Penicillium. This fungus was discovered by Alexander Fleming and is responsible for producing the antibiotic known as penicillin, which has been vital in treating bacterial infections.
Penicillin is a groundbreaking antibiotic that was discovered in 1928 and has since transformed the treatment of bacterial diseases. The genus Penicillium was observed by Fleming as being effective against bacteria due to the substance it released. This substance was later called penicillin. Notably, penicillin G, a narrow-spectrum antibiotic, contains three major functional groups which are vital for its antibacterial activity. These include the thiazolidine ring, the beta-lactam ring, and a variable side chain. Each of these functional groups comprises two simpler functional groups. For instance, the beta-lactam ring includes an amide bond and a four-membered lactam ring. The discovery and use of penicillin marked a new era in medicine, saving countless lives and highlighting the significance of accidental discoveries in scientific breakthroughs. Penicillin G is normally administered intravenously or intramuscularly and remains an essential treatment option for several bacterial diseases.
