Answer:
a. <u>A</u><u> describes the effect of light intensity on photosynthesis.</u>
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 <u><em>the intensity increases steadily, so does the rate</em></u>- 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 <em>carbon dioxide or the temperature</em> limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
When it is ordered by the doctor. The only reason to take an anabolic steroid is to follow a doctors order. Anabolic steroids can lead to serious health problems like infertility, liver cancer, paranoia, heart disease, and increased cholesterol.
Answer:
Eukarya
Explanation:
According to the given information, the observed cells have nuclei and chloroplasts. The presence of a well-defined nucleus and other membrane-bound organelles such as chloroplasts is a feature of eukaryotic cells. All the eukaryotic organisms are assigned to the Domain Eukarya. Therefore, the observed cells belong to the domain Eukarya. Due to the presence of chloroplasts in them, these cells may belong to the kingdom Plantae of domain Eukarya. Domains Archaea and Bacteria include prokaryotic organisms.
Answer:
Increase in kinetic energy of the gases
Explanation:
The direct sunlight will heat up the molecules making up the gases in the balloon.
Kinetic energy resulting from the heating of these particles will make them become randomized. They then begin to move more haphazardly colliding vigorously with themselves and the wall of balloon.
According to Charles's law "the volume of a fixed mass of gas is directly proportional to its temperature provided pressure remains constant" .
The sunlight heats the balloon and causes a rise in temperature. This will make the gas volume to increase and the balloon expands.
