The given statement is False.
The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.
The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.
The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
Answer:
All types of living organisms use cellular respiration for the production of energy from food molecules such as glucose.
Explanation:
Respiration is energy releasing process which occurs in mitochondria of the cell. Respiration has two types i. e. Aerobic and anaerobic respiration. In aerobic respiration, energy is released from the breakdown of glucose molecules with the addition of oxygen while anaerobic respiration is the release of energy from breakdown of glucose molecules without the use of oxygen.
The correct answer is a Bar Graph.
Of the total Earth's surface, approximately 20 percent is covered with deserts. The majority of the desert takes place in the area band situated along the 30 degrees latitude in North and 30 degrees latitude in the south. Even some of the deserts are also situated in the regions of mountains.
There are four prime kinds of desert found in the planet. These are:
1. Subtropical deserts: They are the hottest deserts. They are found in Africa, Asia, North America, and South America.
2. Coastal deserts: They occur in cool to warm regions along the coast like the Atacama Desert in Chile and Namib Desert in Africa.
3. Cold winter deserts: They are also known as semi-arid deserts. The Great Basin, the Colorado Plateau, and the Red desert are all cold winter deserts.
4. Polar deserts: They are found in the Antarctic and Arctic regions.
