Answer:
Proximal convoluted tubule
Explanation:
The major work of re-absorption is carried out in nephron by the proximal convoluted tubule (PCT). The PCT re-absorbs all the essential nutrients such as amino acid, potassium, glucose etc. and water driven by passive transfer based on concentration gradient. Along with gradient, pH of the urine also affects the re-absorption. Based on the pH of the urine (basic or acid), re-absorption of ionized acid increases or decreases.
Answer:
1. They play a key role in seed dispersal, allowing their forest environment to continue to grow and thrive.
2. Resist parasites that cause malaria, some cancers, and a number of other pathogenic bacteria
3. Loss include climate change, deforestation, habitat degradation, and hunting
4. Climate change
5. One of the quickest ways we can lower our collective greenhouse gas emissions is to eat less meat.
The answer is Domain. It is also referred to as Superkingdoms. There are three domains in current classification system namely; Archaea, Bacteria, and Eukarya. The first two classify single-celled organisms whose cells have no nucleus while Eukarya classifies organism that have a nucleus bound by a membrane. The difference between Archaea and Bacteria is their membrane structure; Archaea’s membrane is characterized by membrane lipids that are branched hydrocarbon chains attached to glycerol by ether linkages, while Bacteria’s is made of unbranched fatty acid chains attached to glycerol by ester linkages.
Gradient = difference in elevation/horizontal distance
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step.
