Answer:
Ans1) Common Shapes of Bacteria
Coccus: spherical or round
Bacillus: rod shaped
Spiral: curve, spiral, or twisted
Ans2) Bacteria are classified into five groups according to their basic shapes:
spherical (cocci),
rod (bacilli),
spiral (spirilla),
comma (vibrios) or corkscrew
(spirochaetes)
Greenhouse effect is the natural phenomenon which makes the Earth's atmosphere favorable for any form of life. As the sun's rays radiates into the atmosphere, some are deflected while some are absorbed. The Earth reflects this back, causing the heat to be trapped. At night, this keeps the Earth warm enough. Without the greenhouse effect, nights would be too cold and days would be too hot that life cannot be sustained.

Explanation: Muscle tissue is a soft tissue that makes up most of the tissues in the muscles of the human muscular system. It is the only type of tissue that has cells with the ability to contract. Skeletal muscle tissue is attached to bones by tendons.
Answer:
17.5 g
Explanation:
Given data
- Mass of solution to be prepared: 50.0 grams
- Concentration of the salt solution: 35.0%
The concentration by mass of NaCl in the solution is 35.0%, that is, there are 35.0 grams of sodium chloride per 100 grams of solution. We will use this ratio to find the mass of sodium chloride required to prepare 50.0 grams of a 35.0% salt solution.
