Cyanobacteria is a bacterium that uses the process of?
A bacterium known as cyanobacteria uses the process of photosynthesis, in which water molecules are split into oxygen, protons, and electrons using the energy of light.
A phylum of bacteria that derives its energy from photosynthesis is known as cyanobacteria, also known as blue-green algae and Cyanophyta. It is believed that the ability of cyanobacteria to perform oxygenic photosynthesis changed the early reducing atmosphere into an oxidizing one, which significantly altered the composition of life forms on Earth by promoting biodiversity and driving oxygen-intolerant organisms to the brink of extinction. According to the endosymbiotic theory, cyanobacterial ancestors of plants and eukaryotic algae developed chloroplasts through endosymbiosis.
Although some species of cyanobacteria may also employ hydrogen sulfide, as is the case with other photosynthetic bacteria, water is typically used as an electron donor and oxygen is produced as a byproduct. The Calvin cycle is used to turn carbon dioxide into carbohydrates. The photosynthetic apparatus is typically encased in thylakoids, which are folds in the cell membrane.

pls help me!!!!
Answer:
In photosynthesis, reactants such as carbon dioxide and water are used to create products such as glucose and oxygen. In cellular respiration, glucose and oxygen are used as reactants to create products such as carbon dioxide and water. The organelle involved in photosynthesis is the chloroplast, which contains chlorophyll and other pigments that absorb sunlight to convert it into chemical energy. The organelle involved in cellular respiration is the mitochondria, which converts the chemical energy in glucose and oxygen into a form that cells can use. Photosynthesis and respiration are a cycle because they are interconnected and dependent on each other. The glucose produced during photosynthesis is used as a reactant in cellular respiration, while the oxygen produced during photosynthesis is used as a reactant in cellular respiration. The carbon dioxide and water produced during respiration are used as reactants in photosynthesis.
what critical role do neurotransmitters play in the nervous system
Neurotransmitters are the substances that the nervous system uses to send and receive signals between neurons and between neurons and muscles.
Neurotransmitters in the body are frequently referred to as "chemical messengers." In the synaptic cleft (the small gap between the synapses of neurons), two neurons converse with one another. In this case, electrical signals that have traveled up the axon are momentarily changed into chemical signals by the release of neurotransmitters, leading to a particular reaction in the receiving neuron.
One of three effects that a neurotransmitter can have on a neuron is either excitatory, inhibitory, or modulatory.
While an inhibitory transmitter hinders it, an excitatory transmitter encourages the creation of an electrical signal known as an action potential in the receiving neuron. The receptor that a neurotransmitter binds to determines whether it has an excitatory or inhibitory effect.
Neuromodulators are a little different and can affect a lot of neurons at once because they are not limited to the synaptic cleft between two neurons. neuromodulators are a little different and can affect a lot of neurons at once. Thus, neuromodulators control populations of neurons while simultaneously functioning more slowly than excitatory and inhibitory transmitters.
The majority of neurotransmitters are either neuropeptides, amino acids, or tiny amine compounds. About a dozen small-molecule neurotransmitters and over 100 distinct neuropeptides are currently known, and researchers are continually learning more about these chemical messengers. Numerous nervous system activities as well as the regulation of body processes are influenced by these substances and their interactions.

Part E: Estimate Greenhouse Gas Emission
You’ll design your eco-friendly home to reduce the use of carbon dioxide compared to the average home in the state. Estimate greenhouse gas emissions for your house. Use these three government tools to generate the data you need.
First, go to the US Energy Information Administration and click “Average monthly residential electricity consumption, prices, and bills by state.” Find your state and the average kilowatt-hours of electricity used per month in your state. Multiply that number by 12 to get the amount of energy used in one year.
Then visit the EPA's Greenhouse Gas Equivalencies Calculator and enter the kilowatt-hours of energy for one year into the “If You Have Energy Data” box. Select kilowatt-hours of electricity and click Calculate. The kilowatts converted into emissions equivalents (such as miles driven and average household energy). This information will give you a better perspective on the greenhouse gas emissions for the average home in your state.
Finally, click the EPA's Power Profiler and enter the ZIP code. Choose one of the electrical companies listed (any one will work) and press Enter. Scroll down to see how much of the energy in this ZIP code comes from renewable energy and nuclear energy (a nonrenewable, cleaner energy source) compared to fossil fuel sources (oil, coal, and gas). You’ll also see bar graphs that compare your ZIP code’s energy profile to the national average.
Based on the data you gathered, answer the following questions:
What conclusion can you draw about the emissions of greenhouse gases for the average home in your state or ZIP code? What factors do you think contribute to this emission rate?
How do the emissions in your ZIP code compare to greenhouse gas emissions across the nation? Even if it’s better than the national average, is there room for improvement?

What causes directional selection?
Directional selection is caused by changes in the environment that favor individuals with a certain trait, while selecting against individuals without that trait.
directional selection, If there is a new predator that preys on small animals, animals with a larger body size may have an advantage and be more likely to survive and reproduce. Over time, this can lead to a shift in the distribution of body size within the environment population, directional selection with more individuals having larger body sizes. Another example could be if a drought occurs and the water resources become scarce, the plants or animals that are able to survive in dry environment conditions would be favored over those that need a lot of water.
