where do the light-independent reactions take place in cam photosynthesis?
Answers
Answer:
Explanation: In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
The place from where the light-independent reactions occur in cam photosynthesis would be:
Chloroplast stroma
PhotosynthesisThe chloroplast stroma is where CAM photosynthesis takes place. It starts when the plant's stomata open at night, allowing CO2 gas to flow into the cytoplasm of CAM mesophyll cells.
Carbon dioxide is exclusively collected in CAM plants at night, when the stomata open.
Malic acid is turned back to carbon dioxide during the day.
When the sun shines, light reactions produce energy for the Calvin cycle, which allows carbon dioxide to be transformed into sugars.

Scientists have observed a gradual increase in temperatures in locations all across Earth, an event often called . The increase in temperature is one aspect of , a long-term change in weather patterns.
Answers
Answer:
Climate or Global Warming
Dunno what you're asking exactly-
A long-term change in the typical weather patterns that have come to characterize local, regional, and global climates on Earth is referred to as climate change.The phrase is synonymous with a wide variety of observed outcomes that are a result of these changes
What is a long-term change in weather patterns?
Storms, heat waves, floods, and droughts are just a few of the disasters that are getting worse as a result of rising temperatures.Warmer temperatures produce an atmosphere that can hold onto, release, and gather more water. This alters weather patterns such that wet areas get wetter and dry ones get drier. The long-term pattern of the weather in a place is called the climate.Hour by hour, day by day, month by month, or even year by year, the weather might change.A region's climate is determined by its weather patterns, which are typically monitored for at least 30 years.The climates in different places of the world vary.When the weather is consistent for several days or weeks at a time, a weather pattern develops.Cold weather, wet and rainy weather, and hot and dry weather are a few typical weather patterns.Heat waves, flooding, and blizzards can occur as a result of persistent weather patterns. Climate Change Causes... Greenhouse Gases.... Reflectivity or Absorption of the Sun's Energy.... Changes in the Earth's Orbit and Rotation.... Variations in Solar Activity.... Changes in the Earth's Reflectivity.... Volcanic Activity. These phenomena cover changes like sea-level rise, ice mass loss in Greenland, Antarctica, the Arctic, and mountain glaciers around the world, changes in flower/plant blossoming, and extreme weather events, in addition to the higher temperature trends indicated by global warming. The average thickness of 30 well-studied glaciers has declined by more than 60 feet since 1980, indicating that glaciers are thinning. Due to climate changes, the ocean level is rising, glaciers are melting, CO2 levels in the atmosphere are rising, the forest and wildlife are disappearing, and water life is also being disrupted.In addition, it is predicted that many species of plants and animals would become extinct if this trend continues.To learn more about weather patterns refer

Use data from the lab to support claims you make, and provide compelling reasoning. Make an effort touse proper writing conventions in your summary (such as good punctuation, spelling, and capitalization)
Answers
Answer:
Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. Simply, spectroscopy is the study of color as generalized from visible light to all bands of the electromagnetic spectrum; historically, spectroscopy originated as the study of the wavelength dependence of the absorption by the gas phase matter of visible light dispersed by a prism. Matter waves and acoustic waves can also be considered forms of radiative energy, recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory as well. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics, chemistry, and astronomy, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.
The spectrum is determined by measuring changes in the intensity or frequency of this energy. The types of radiative energy studied include: Electromagnetic radiation was the first source of energy used for spectroscopic studies. Techniques that employ electromagnetic radiation are typically classified by the wavelength region of the spectrum and include microwave, terahertz, infrared, near-infrared, ultraviolet-visible, x-ray, and gamma spectroscopy. Dynamic mechanical analysis can be employed to radiating energy, similar to acoustic waves, to solid materials. The types of spectroscopy also can be distinguished by the nature of the interaction between the energy and the material example:Absorption- when energy from the radiative source is absorbed by the material. Elastic scattering and reflection spectroscopy determine how incident radiation is reflected or scattered by a material. Crystallography employs the scattering of high energy radiation, to examine the arrangement of atoms in proteins and solid crystals. Coherent or resonance spectroscopy are techniques where the radiative energy couples two quantum states of the material in a coherent interaction that is sustained by a radiating field. Spectroscopic studies are designed so that the radiant energy interacts with specific types of matter.

what route does a red blood cell take to travel from the lung to the kidney
Answers
Answer:
aorta
Explanation:
the red blood cell goes into the kidney trunk and other lower limbs delivering oxygenated blood around the body. They typically last for 120
days before they die.
The blood enters the heart from left atrium. It leaves through the mitral valve into the left ventricle of the heart. The left ventricle then pumps blood through the aortic valve and into the aorta that feeds the rest of the body through a system of blood vessels.
What is function of lungs?The lungs allow us to breathe and they carry oxygen into body (called inhalation) and pass carbon dioxide out called exhalation.
Kidney remove toxins and waste, and excess water from the bloodstream, which is carried out of the body in the form of urine. They helped to produce hormones to form red blood cells, and they turn vitamin D into its active form in the body.

triggering of the muscle action potential occurs after
Answers
Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.
An action potential is an electrical signal that travels along the cell membrane as a wave.
This action potential (muscle action potential) drives the contraction of muscle fibers.
When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.
Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.
