Which of the following things grow?
-
Road
-
Pen
-
Water
-
Tree
The living organisms are composed of cells. The cells divide and the body of the organisms show growth due to the increase in the number of cells. The trees are the living organisms and show the process of growth. Road, pen and water are non-living organisms which do not show the process of growth.
Organisms respond to environment stimuli which would be
-
Physical
-
Chemical
-
Biologocal
-
All the above
Stimuli can be of any type whether physical or mechanical, biological as in response to another organic thing or chemical including chemical compounds or environment.
Which of the following is a living thing?
-
Lamp
-
Car
-

- Reproduction and metabolism
- Response to stimuli.
- Growth and development.
- Adaptation through evolution
Biomass ferments to form _________ in the presence of air.
-
methane
-
ethane
-
oxygen
-
nitrogen
Microbial conversion of organic matter to methane called Biogas has become attractive as a method of waste treatment and resource recovery. This process is anaerobic(absence of oxygen) and is carried out by action of various groups of anaerobic bacteria.
Three basic points about this process are that most of the important bacteria involved in biogas production process are anaerobes and slow growing, a greater degree of metabolic specialization is observed in these anaerobic microorganisms and that most of the free energy present in the substrate is found in the terminal product methane. Since less energy is available for the growth of organism, less microbial biomass is produced and, consequently, disposal of sludge after the digestion may not be a major problem.
Hence, the statement is false.

The high boiling point of water is advantageous to living organisms because
-
The environment seldom reaches the boiling point of water
-
Organisms can easily boil off enough water to keep themselves cool
-
It allows organisms to spread heat evenly throughout their bodies
-
Organisms can absorb a great deal of heat before they reach the boiling point from organisms and population
The high boiling point of water is advantageous to living organisms because organisms can absorb a great deal of heat before they reach the boiling point from organisms and population. Thus the organisms will not be affected by the high temperature because water can absorb the heat and maintain its homogeneity by uniformly dissipating it.

The living organisms can be unexceptionally distinguished from the non-living things on the basis of their ability for
-
Growth
-
Reproduction
-
Movement
-
Responsiveness to touch
-
All of the above
Living things are lively and active and exhibit characteristics of life, like growth, movement, reproduction, response to stimuli (like touch, smell, light) . These activities are done by the cells of which the living things are made up of. Some examples of living things around us are human beings, animals, plants and microorganisms.

-
Energy
-
Consciousness
-
Reproduction
-
Growth

A dead organism does not grow. Although, some non-living things can increase in size e.g. mountains, stones. The process is called ______
-
accretion
-
accumulation
-
adaptation
-
organisation
- Non-living things increase in size due to the addition of similar materials to their outer surface, they include crystals, glaciers, stones and mountains
Living organisms must maintain a constant internal environment.
-
True
-
False
Living organisms must maintain a constant internal environment while living in a constantly changing external environment. Maintaining the internal environment is important because the processes that keep the cell alive can only take place under certain conditions. There are different processes that occur in the body to maintain the constant internal environment such as diffusion, osmosis, homeostasis, active transport, passive transport, endocytosis, exocytosis, etc. Homeostasis helps to maintain an equilibrium of an internal environment.
Characteristics of living things are
-
Made up of cells
-
Growth
-
Response
-
All of the above
All living things and dead are made up of the cells which perform life processes for maintaining life. They give the response to the stimulus or environmental factors. But growth is the characteristic of both living and dead as dead like wood shows growth by the absorption of water. Thus, the growth is the characteristics of living things but not the defining or fundamental properties of living things. Hence, the correct answer is option D.

The guillotine is a device designed for carrying out executions by decapitation. It consists of a tall upright frame in which a weighted and angled blade is raised to the top and suspended. The condemned person is secured at the bottom of the frame, with his or her neck held directly below the blade. The blade is then released, to fall swiftly and sever the head from the body.
In nonliving things
-
Growth occurs from inside
-
Growth occurs from outside
-
Reproduction is asexual
-
Cell is the structural unit
- Non-living things do not grow through internal metabolic functions but by adding on from the outside. Non-living things do not need the energy to continue to exist. Some nonliving things such as crystals grow by accumulating more of the same material of which they are made.
- Living things exhibit growth, movement, reproduction, respiration and metabolism. Living things use energy, respond to stimuli and adapt to their environment.
- So, the correct answer is 'Growth occurs from outside'.

The distinguishing property of crystal is
-
Growth is external
-
Growth is internal
-
Growth is discontinous
-
None of the above
The crystals are the non-living forms which show an external form of growth. The atoms form the nuclei and then the other molecules in the solution when cooled come together forming an aggregated structure. The new atoms and molecules are added from the outside and so, the growth in the non-living forms is always external. There are no cells which divide and show internal growth as in the living forms.
