If a wave has a wavelength of 50 m and is traveling through water that is 30 m deep, what kind of wave is this?.
f a wave has a wavelength of 50 m and is traveling through water that is 30 m deep. the wave is deep water wave.
What is wavelength?The distance between the two crests or troughs of the light wave is known as the wavelength of light. Using the Greek letter lambda (), it is identified. As a result, wavelength refers to the separation between one wave's crest or dip and the following wave.
Light can be described by two equations since it possesses both wave- and particle-like characteristics:
Where,
The light's velocity is v.
The wavelength of light is.
The frequency of light is f.
E is the light wave's energy.
Planck's constant, h, is 6.64 10-34 joule/second.

at which point would you expect the largest number of voltage-gated sodium channels to be in an inactivated state?
Voltage-gated sodium channels are found in many different cell types throughout the body, whereas epithelial sodium channels are mostly found in the skin and kidney.
What voltage will cause sodium channels to begin to open?The activation gates open when the membrane potential rises to approximately 55 mV (in this case brought on by an action potential), allowing positively charged Na+ ions to enter the neuron through the channels and raising the voltage across the neuronal membrane in human neurons to +30 mV.
Why do sodium channels become inactive?Voltage-gated Na(+) channels (VGSCs) start action potentials, which leads to quick electrical signal transmission across cell membranes and between cells. In addition to opening VGSCs, depolarization of the cell membrane also results in a nonconducting condition known as inactivation.

Write a story about a carbon atom on its path through cell respiration and photosynthesis. Please help me
The story is a carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon atoms start out as part of glucose. During cellular respiration, glucose is broken down into smaller carbon molecules. Eventually, the carbon atoms in carbon dioxide are released into the atmosphere. During cellular respiration, carbon dioxide is released as a waste product.
This carbon dioxide can be used by photosynthetic cells to form new carbohydrates. Oxygen gas is also required for cellular respiration to serve as an electron acceptor. They use the sun's energy to chemically combine carbon dioxide with hydrogen and oxygen from water to form sugar molecules. Photosynthesis produces glucose that is used in cellular respiration to produce ATP. The glucose is then converted back to carbon dioxide.

how has the change in land use affected the balance of photosynthesis and respiration? how could we change land use to stabilize or reverse this trend?
If there is a change in land use, it will cause the plant to decrease so that the reduction in carbon storage is also reduced, so it becomes a contributor to global climate change. To stabilize this situation, we can use land with go-green innovations.
The by-product of respiration is CO₂ which will be released into the atmosphere. The process of photosynthesis in plants requires CO₂ from respiration. When there is a change in land use, it will cause a decrease in vegetation so the reduction in carbon storage is also reduced. So, the atmospheric concentration of CO₂ (carbon dioxide) from respiration will increase thereby contributing to global climate change.
