Answer:
Proximal tubule is involved in reabsorption from blood to filtrate while Distall tubule is also involed in secretion from blood to filtrate.
Explanation:
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.
Answer: 7
Explanation: During translation, several codons have special functions which they serve. AUG is called the initiation codon, it signals the beginning of polypeptide synthesis and also codes for methionine in the internal positions. UAA, UAG and UGA are called termination codons because they do not code for any known amino acid. They signal the end of a polypeptide synthesis.
Each codon is made up of three nucleotides. The number of codons between the initiation codon UAG and the termination codon UGA in the mRNA is seven, thereby encoding seven amino acids.
See the attached diagram for further illustration.
Answer:

Explanation:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle
