Answer:
Cyanobacteria. (Ans. A)
Explanation:
Cyanobacteria are prokaryotes, are a phylum of bacteria. They are also called as blue-green algae and obtain their energy through the process of photosynthesis. They are commonly found in fresh water and terrestrial environment such as land, in rocks even in animal cells (fur).
Cyanobacteria are photosynthetic (oxygenic) bacteria. They harvest the energy of sun, absorb carbon dioxide and release O2. Cyanobacteria also contain chlorophyll such as plants and algae and convert carbon dioxide to sugar through the process of carbon fixation.
Cyanobacteria lack nucleus and other organelles like found in algae and plants. Instead of these they have double outer cell membrane and folded inner thylakoid member which are used in the process of photosynthesis.

The teeth of mammals do not have the similar function to perform. They have different types, number and sizes of teeth that are equipped to perform different functions.
Example: Human beings have incisors,canines, molar and premolar. The incisors are used to cut the food and hold the food.

Hence, the given statement is false.
since he memorized 15, he has only 10 left. so it should be 10/25
Answer:
A) ADH secretion decreases. B) Urine osmolarity decreases.
Explanation:
Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.
A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.
B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.
