Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis. A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and <span>osmosis.</span>

Explanation:
Environmental contamination reduces total testosterone oxido-reductase activity in females.- <u>True</u>
Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme testosterone oxi-reductase facilitates the of testosterone to the androgen DHT. Enzyme specificity is affected by pH, temperature and the presence of inhibitors.
In temperatures beyond its optimal range, these may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. Testosterone would no longer be able to bind to the active site, and thus would not be converted.

The pond ecosystem includes abiotic factors such as soil, precipitation,temperature etc as well as biotic communities that live there such as lilies,fish,insects, and more
Every species is assigned a standard two-part name of genus and species. ... Organisms are grouped into species partly according to their morphological, or external, similarities, but more important in classifying sexually reproducing organisms is the organisms' ability to successfully interbreed.
