Answer:
Virus is the only organism which is considered as both living and non living organism.
Explanation:
Virus has the characteristics of both living and non-living organism. The living character is that it is formed from DNA and RNA molecule and the ability to reproduce, while the non living character is that they are present in the form of crystals when they are out of the host cell. Due two these living and non-living characteristics of virus, people have some misconception. So it is clear that virus has both living and non living characteristics.
Answer:
The correct answer is - autonomic (visceral) reflexes.
Explanation:
Autonomic or visceral reflexes is somewhat similar somatic reflexes but visceral reflex takes place in various soft tissues and muscles present in soft organs such as digestive, cardiac muscles, reproductive muscles, and others.
Visceral or autonomic reflexes include activation of smooth muscles, glands, and dilation of pupils, vomiting, defecating, sweating, blood pressure and many more body function regulating.
Thus, the correct answer is - autonomic (visceral) reflexes.
The main difference between haploid cells and diploid cells is diploid cells have two complete sets of chromosomes, while haploid cells only have one complete set of chromosomes.
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.
