Answer:

O B. Restriction enzymes

Explanation:

Restriction enzymes has the ability to recognize specific DNA sequences and cut them in a specific manner in order to produced by the bacteria as a defense mechanism against foreign DNA containing substance such as viruses etc. This restriction enzyme is also called restriction endonucleases. This is a cloning tool that bacteria produced naturally in order to defend itself from the infection of virus.

Anna [14]

Answer:

Long life span

Explanation:

A model organism is a non  human specie that is used for study in order to understand a particular biological phenomena.

One of the qualities of a model organism is that; It should have a short life span this will make it more amenable to experimental manipulation due to short generational time. Therefor Long life span will not be a desirable characteristic.

Other desirable characteristic includes ease of growth and production of many offsprings.

Also common genetic mechanism with other organisms, they should share some degree relatedness.

kari74 [83]

Answer:

d. neither the light reactions nor the Calvin cycle

Explanation:

Calvin cycle is the name given to a set of chemical reactions that occur in the chloroplast stroma. The chemical reactions that make up the Calvin cycle occur in the carbon fixation step, one of the photosynthesis phases. In this cycle, CO2 is reduced to glyceraldehyde 3-phosphate and ribulose 1.5 bisphosphate, CO2-acceptor, is regenerated.

Photosynthesis is initiated by light reactions, which use light energy to store and transport energy-supplying molecules such as ATP and NADPH.

Neither the Calvin Cycle nor light reactions requires glucose, these processes are initiated by other molecules and are intended to provide products for photosynthesis to occur.

maks197457 [2]

Answer:

The motion of an object is defined by its change in position and direction.

Explanation:

Motion is the action of changing location or position. Motion is usually brought about by an external force.

Kinematics is the study of motion  alone without regard to the forces or energies involved.

The various types of motion include:

Translational motion : This is motion that occurs along a straight line. For example, a car travelling on a straight road.

Rotational motion: this motion that occurs in a circular path. For example, movement of the earth round the sun.

Oscillatory  motion: this is a periodic or to and fro motion that occurs between two points. For example, a swing or a simple pendulum.

Random or zigzag motion: This is motion that occurs in no particular pattern or direction. for example, the movement of dust particles.
