Why can the Calvin cycle work at night, but the photosystems cannot?
Answer:
Because photosystems need light to operate (photo=light).
Photosystems use energy from sunlight, Calvin systems use energy stored in the plant.
Explanation:
The Calvin cycle is a dark reaction because it does not need sunlight. Although it can happen during the day, this process does not require energy from the sun to work. Other names for the Calvin cycle include the Calvin-Benson cycle, light-independent reaction, carbon fixation and C3 pathway.
The Calvin cycle work at night, but the photosystems cannot because the photosystem needs direct energy from sunlight to be operated functionally.
What are Photosystems?Photosystems may be defined as functional and structural units of protein complexes involved in photosynthesis that contains chlorophyll pigments that absorb light energy for photosynthesis.
The Calvin cycle is a light-independent reaction that occurs during the night as well as daytime. But it utilizes the stored energy to make its final products with the help of several enzymes.

The person's risk of cardiovascular disease would decrease.
The person's bad cholesterol would decrease.
The person’s good cholesterol would increase.
Answer:
The person's risk of cardiovascular disease would increase.
Explanation:
saturated refers to all single bonds in the hydrocarbon chain, meaning no kinks in the chain. The hydrocarbon has the most number of carbons it can have, as there are all single bonds. If the hydrocarbon has even one less carbon, there would be kink, and it would be unsaturated and liquid. Our body needs less carbon, so unsaturated fats are better. But having saturated fats means no liquid, rather solid, which means harder for the blood to get to the heart. So your risk would cardiovascular disease would increase

Most fossils are deposited in water. How do scientists find them
Answer:
Most fossils are found in sedimentary rocks, those rocks produced by the accumulation of sediment such as sand or mud. Wind and other weathering conditions wash away sediment on land, depositing it in bodies of water. For this reason, fossils of sea creatures are more common than those of land creatures.
Fossils are remain of decayed plants and animals over a very long period of time. Most fossils are found in sedimentary rock deposits which might have been exposed due to erosion, quarrying or at shore.
Fossils are usually found in sedimentary rock deposits, which might have become exposed to the surface after thousands to millions of years after deposition began. Since deposits of rock stretch over a very large area, fossils deposited in water which are preserved in sedimentary deposits may be exposed at shore. Also, fossils such as sea shells mollusk are usually washed up shore in large amount.Therefore, fossils could also be found during quarrying and rock cutting process.

D. methane
Answer:
Starting billions of years ago, algae lowered the
atmosphere.
levels in the carbon dioxide - C.
Algae has been found to have lowered the atmospheric carbon dioxide levels in the environment. Thus, the correct option is C.
What is Algae?In the primitive world, the initially formed organisms such as algae, were found responsible for the production of large amounts of oxygen in the atmosphere. This was possible by the algae present in atmosphere, as they were able to carry out the process of photosynthesis similar to plants, where the food is synthesized in the presence of sunlight, water and carbon dioxide (CO₂), and in return, it generates food and oxygen, on which the organisms are dependent on for their living.
Thus, these algae were responsible for the changes in the atmosphere, by converting carbon dioxide (CO₂) into oxygen and hence lowering the level of carbon dioxide.
Therefore, the correct option is C.

Oxygen is a reactant in cellular respiration. Which term best describes oxygen
in photosynthesis?
Answer:
ANSWER: Oxygen is a product of photosynthesis.
Explanation:
Photosynthesis is a chemical reaction that occurs in plants. Photosynthesis uses ATP energy from sunlight to convert Carbon Dioxide and Water into Glucose. Oxygen is also formed during photosynthesis.
Oxygen is the product of photosynthesis, where water and carbon dioxide are the reactants and G3P and oxygen are the products. This contrasts with cellular respiration, where oxygen is a reactant.
Explanation:When it comes to the role of oxygen in photosynthesis, it is best described as a product rather than a reactant. In the process of photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) and, using the energy from sunlight, convert these reactants into glucose (C6H12O6) and oxygen (O2). The correct statement among the options provided would be option (b), which states that in photosynthesis, chlorophyll, water, and carbon dioxide are reactants, while G3P (glyceraldehyde-3-phosphate) and oxygen are products.
This contradicts the role of oxygen in cellular respiration, where oxygen serves as a critical reactant. In cellular respiration, oxygen is used to break down glucose, producing ATP, water, and carbon dioxide as waste products.

which type of stimulus do mechanoreceptors detect? sound pain heat light
Mechanoreceptors detect mechanical stimuli such as touch, pressure, sound waves, and motion. These receptors initiate nerve impulses when physically deformed by an outside force. Several types of mechanoreceptors, including Merkel cells and Pacinian corpuscles, are specialized for different kinds of mechanical detection.
The correct option is 'A'.
Mechanoreceptors detect mechanical forces, and the type of stimulus they are especially tuned to includes touch, pressure, sound waves, and motion. These receptors enable us to sense various forms of mechanical input such as the texture we feel via touch or the vibrations we hear as sound.
The process by which they work involves the deformation of the receptor upon the application of a mechanical force, which initiates nerve impulses in sensory neurons.
Mechanoreceptors are categorized based on the threshold of stimulus they respond to.
Low-threshold mechanoreceptors respond to non-damaging, light stimuli, while high-threshold mechanoreceptors respond to stimuli of a higher intensity and are considered a type of nociceptor, contributing to our sense of pain when the applied pressure is severe enough, such as pinching or crushing.
They can be found in various locations, including the skin, where they are essential for the sense of touch, and in the inner ear, where they are necessary for the senses of hearing and balance.
Distinct types of mechanoreceptors are specialized for detecting different kinds of mechanical stimuli, for example, Merkel cells detect low-frequency vibrations, Pacinian corpuscles sense deep pressure and vibration, and Ruffini corpuscles respond to skin stretching.
This question is incomplete, the complete question is :
which type of stimulus do mechanoreceptors detect?
