Question 26

Process of respiration

Answer 26

Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells). ... Note the number of oxygen, carbon dioxide, and water molecules involved in each 'turn' of the process.

Question 27

Process of nutrition

Answer 27

There are five steps in the process of Nutrition in animals. These are: Ingestion, Digestion, Absorption, Assimilation and Egestion. Ingestion: is the process of taking food in to the body or 'eating of food' by the animal. ... Blood carries the absorbed food to all the parts of the body

Question 28

Process of reproduction

Answer 28

In the reproductive process, a male sperm and a female egg provide the information required to produce another human being. Conception occurs when these cells join as the egg is fertilized. ...

Question 34

The process of germination

Answer 34

Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. ... When water is plentiful, the seed fills with water in a process called imbibition. The water activates special proteins, called enzymes, that begin the process of seed growth

Question 35

The process of tropism

Answer 35

A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch. ... This type of growth occurs when the cells in one area of a plant organ, such as a stem or root, grow more quickly than the cells in the opposite area.

Question 36

The process of hybridisation

Answer 36
