Diatom Cells are enclosed in a cell wall made up of silica or hydrated silicon dioxide namely frustule. The frustule has small walls where nutrients enter, enabling it to perform photosynthesis the same way plants do.
Passive is when the channels don't need energy to do so and active is when they need energy
The process that transports
solutes, including many drugs, into the tubular fluid is called tubular
secretion. Under this process, there is transfer of materials from peritubular
capillaries to the renal tubular lumen and the secretion is caused mainly by
active transport and passive diffusion.
The correct answer is B. Meet current and future resource needs.
Explanation:
Sustainability implies an equilibrium between the natural resources available and the resources humanity requires. This equilibrium is reached when the natural resources extracted from nature are enough to satisfy human needs without depleting the resources or causing these are not available in the future. In this context, the goal of sustainable development is to make sure now and in the future resource needs are meet (option B). Moreover, this is possible through actions such as recycling, reducing deforestation, creating environment-friendly technologies, among others that reduce the depletion of resources or preserve the environment.
