A. A describes the effect of light intensity on photosynthesis.
Answer: A
Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
This organism is a coyote brush or the Baccharis pililaris. It is a shrub that is a family of daisy. They are mostly found in California, Washington and Oregon. This plant takes a different shape depending on the environment where it is found. It grows in a chaparral biome where there is little biodiversity and a habitat of only few species.
Answer:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. ...
Biogeography. ...
Fossils. ...
Direct observation.
Explanation:
Answer – A (Sedimentary; Metamorphic)
When sufficient heat and pressure is applied, sedimentary rock can be transformed directly into metamorphic rock. As a matter of fact, metamorphic rocks were at a time sedimentary rocks (or sometimes igneous rocks) that have been changed by heat and pressure.
Answer: As water is cooled, its density increases until it reaches about 4˚ Celsius.
hope this helps you :D
i apologize if i got it wrong
