The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
Physical exercise preserves bone mass. Measurements of bone biomarkers may reflect the events in bone during exercise. Fifteen healthy, well-trained individuals (7 men and 8 women) performed a running test for 21 min until exhaustion. Venous blood samples were drawn before and 30 min after the exercise to measure the levels of osteocalcin, the carboxyterminal propeptide of type I procollagen (PICP) and the carboxyterminal cross-linked telopeptide of type I collagen (ICTP). After exercise, the women had a marked increase in serum osteocalcin concentrations (from 7.5±5.0 μg/1 to 11.5±3.0 μg/1), whereas the level was unaffected in the men (from 14.5±3.0 μg/1 to 13.5±4.6 μg/l). In the men there was a marked increase in PICP (from 240±47 μg/1 to 268±56 μg/1) that was not seen in the women (from 244±70 μg/1 to 253±60 μg/1). In neither group did ICTP levels change. In conclusion, significant responses were seen in PICP and osteocalcin during exercise, indicating that such measurements may be valuable for the further delineation of the effects of physical activity on bone. Furthermore, the different responses in men and women point to interesting areas for future studies.
In the given scenario, the weather model is showing light rain, the correct option is B.
<h3>What is a weather station model?</h3>
Current weather circumstances, cloud cover, wind speed, prevailing winds, visibility, heating rate, dew point temperature, atmospheric pressure adjusted to sea level, and pressure change over the last three hours are all depicted in the station model.
As we discovered, the station model is a method of displaying a large amount of weather data on a single area using numbers and symbols.
Meteorologists can quickly glance at the map and see a lot of information this way.
In the given image, the three inverted commas are representing moderate drizzles.
Thus, the correct option is B.

Because it’s time consuming and money consuming to observe from space so models are required
