Answer:
Proximal tubule is involved in reabsorption from blood to filtrate while Distall tubule is also involed in secretion from blood to filtrate.

Proximal Tubule;
It reabsorbs the important nutrients such as water, sodium, potassium, calcium, glucose, aminoacid etc. from the filtrate and send them back into the bloodstream.
Distal tubule;
Although distal tubule is involved in reabsorption of nutrients such as calcium, sodium chloride but it is also in secretion of blood wastes such as drugs into the filtrate. It also help in maintaining the pH of blood by secreting the protons into filtrate and absorbing the bicarbonate ions.

Biodiversity refers to the diversity of biology or living organisms on Earth. The biodiversity is responsible for maintaining various biogeochemical on this planet.
The biodiversity has been drastically affected by the anthropogenic factors which has caused the deterioration of biodiversity.
The main anthropogenic factors are:
1. Habitat fragmentation: the human activities like construction of road passing through the habitat for organisms can lead to habitat fragmentation which could decrease the gene flow in the species.
2. Deforestation: the cutting of trees has led to the extinction of species.
3. Climate change : Global warming is the result of the industrial revolution initiated by humans in 19th century.
4. Exploitation of natural resources: the humans have continuously exploited human resources for their use.
5. Hunting of animals: The hunting of animals is one of the major factor for extinction of animals.
