Answer 1

Answering all questions from top to bottom order:

Answer 1. Histones are the the proteins that are associated with the DNA. They are present in eukaryotes thus, DNA is more packed in them.

Answer 2. Pancreas releases bicarbonate.

Answer 3. Glucose,lactate and amino acids are reabsorbed in the proximal convulated tubule.

Answer 4. pH is 9 where H ion concentration is given.

Answer 5. Hypothalamus regulates pituitary.

Answer 6. Proteins have both amine and carboxyl group.

Answer 7. Blood is pumped from arteries,to arterioles to capillaries to the organs to venules to veins.

Answer 8. During inhalation diaphragm lowers.

Answer 9. Vitamin D is associated with skin.

Answer 10. Startum corneum is made of dead cells.

Answer 11. Neuron creates electrical impulse.

Answer 12. Zygote is produced as a result of fertilisation.

Answer 13. F means fuzzy

f means smooth

Thus when ff X ff then all offsprings will be smooth.

Certain questions are repeated please tick your answers very carefully,for your ease I have written answer in the form of sentences.
