Answer 1

"Indogland" or endocrine gland?

Endocrine glands are those glands which don't have a duct. They release their secretions directly into the blood.

Five diseases caused by VIRUS: AIDS, polio, rabies, ebola and hepatitis.

Five diseases caused by BACTERIA : Tuberculosis, typhoid, diarrhoea, anthrax and peptic ulcers.

Acids are those substances which are sour to taste and produce H+ ions in water. Their pH is less than 7

Bases are those substances which are bitter and release OH- ions in water. Their pH is more than 7.

Answer 2

(1.) 

Endocrine glands are glands of the endocrinesystem that secrete their products, hormones, directly into the blood rather than through a duct.

The majorglands of the endocrine system include the pinealgland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands



(2.)

 Diseases cause by viruses :
AIDS
Chickenpox
Common Cold 
Dengue
Herpes 

 Diseases cause by bacteria :
CholeraStaph Infection
Meningitis
Pneumonia
Tuberculosis



(3.)

ACID
an aqueous solution produces hydrogen (H+) ions.

1. Acids have a sour taste.

2. Acids are corrosive.

3. Acids change the color of certain vegetable dyes, such as litmus, from blue to red.

4. Acids lose their acidity when they are combined with alkalies.



BASE
solution produce hydroxide(OH-) ions in solution.

1. Alkalies feel slippery.

2.Alkalies change the color of litmus from red to blue.

3.Alkalies become less alkaline when they are combined with acids.
