We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
Answer:
adsorption, penetration, biosynthesis, maturation, release
Explanation:
The virus after infecting the cell produces several progenies which after reaching a certain number cause the lysis of the cell and are then released out from it. This process of entering the host by the virus and then lysing the cells to be released is termed as a lytic cycle.
There are 5 stages involved in this lytic cycle:
1. Adsorption - when the virus finds its attachment site on the bacteria it gets attached to the viral receptor and then is adsorbed on the bacteria, this is the first step required to gain entry into the host.
2. Penetration - once the virus is attached to the host the next step is to penetrate it and enter inside the cell. For this, the virus secretes lysozyme and then inserts its genetic material inside the cell.
3. Biosynthesis - this stage involves the utilization of the enzymes and nucleotides of the host to make up the DNA of the phage.
4. Maturation - once the phage DNA is made the next stage is to assemble the phage DNA with the capsid and this is termed as maturation.
5. Release - this step involves the breakage of the plasma membrane of the host cell and the release fo the phage particles.

Answer: Here are the completed options
fuels
components of DNA and RNA
signalling
forming barriers between organelles
digesting enzymes
breaking up lipids for digestion
providing structure
The correct options are
most of the organic matter on our planet (cellulose, chitin, etc.)
Carbohydrates act as Body fuels
providing structure
Explanation:
Carbohydrates are biological molecules and are constituents of starches, sugars, glucose e.t.c and are made up of carbon, hydrogen and oxygen which are the major constituents elements of the most organic matter on the planet.
Carbohydrates is a body fuel that act as the major energy source in the body. It gives and provide energy in the body needed for biological activities.
In plants, carbohydrates make up part of the cellulose, giving plants strength and structure. carbohydrates is to form a structure called the glycocalyx.
Answer:
I can't be sure about the 1st one because I don't have the table. The second one is the same: but my educated guess is C. The third one is surely C. The fourth one is A.
