The caterpillar, which is the larval stage of a butterfly, is very different from its adult form. Which phenomenon is responsibl
BigorU [14]

The correct answer to this question is a: metamorphosis. Many insects take on multiple forms through different parts of their lifecycle. For example, many lepidopteran species (i.e., butterflies) include a caterpillar juvenile stage. To reach the adult stage, the juvenile stage has to go through metamorphosis, where its adult form is strikingly different from its juvenile form.

Answer the following questions about earths spheres to the best of your ability.
Eva8 [605]

Answer:

1 All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). ... Flooding rivers wash away soil. 2 As the global human population continues to grow, so too does our impact on the environment. The ingenuity with which our species has harnessed natural resources to fulfill our needs is dazzling.

3 Humans impact the environment through their interactions in many different ways, such as overpopulation, pollution, and the burning of fossil fuels. Human environment interactions have resulted in impacts, such as climate change, soil erosion, and air pollution. 4 All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). 5 The National Environmental Policy Act of 1969 committed the United States to sustainability, declaring it a national policy “to create and maintain conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations.”

If the calvin cycle slows down, what will happen to the rate of o2 production in ps ii, and why?
Schach [20]
If the Calvin cycle slows down, THE RATE OF OXYGEN PRODUCTION IN PS II WILL BE REDUCED. 
This is because, the light reaction depends on the dark reaction to occur. If the Calvin cycle slows down, the light cycle will have less ADP and NADP+ to work with and this will slow down the production rate of the photosynthetic reaction.
