Answer:
the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).
Answer:
1) Hunger, savor, appetite. Three main biological reasons why we eat. Also, the economic ability to pay for the food. And the fisical capability to go and buy food, to cook.
2) Our physiological needs are the main reason why we choose food. People need energy to survive.
Everyone would like to have the possibility to eat what he wants. But food choices depend on the financial situation, social class, and preferences.
That is why poor people or people who have less money to spend on food, often eat food that can feed more people but it doesn’t have nutritional values. When people have money, they immediately have a wider spectrum of groceries that can choose from.
Explanation:
Savour is equal to enjoying. When people are not hungry they are happier. We choose what to eat depending on the look, taste, smell, texture. As sweets smell good, people consider them the most attractive food. Food is not just the source of nutrition, it is also the source of satisfaction.

Explanation:
sexual reproduction is the process of fusion of male gamete and female gamete producing a genetically different offspring .Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. meiosis leads to variation by forming new combination of alleles from maternal and parental chromosome
(choose which answers suits the question )
Explanation:
Meiosis leads to the formation of gametes which have half the number of chromosomes in the somatic body cells. This means two gametes should fuse together for a new individual to form. The two gametes coming from two different parents carry features from two individuals, and this is the first source of variation.
The process of independent assortment happens during metaphase I where the chromosomes from both parents align on the equator of the cell in an independent way, meaning some from each parent on one side, and the opposite on the other. This means the gamete formed has a mixture of chromosomes from the parent's parents, and this is the second source of variation.
Finally there is the crossing over which happens also in metaphase I where genetic material between the homologous chromosomes is exchanged. This means not the whole parental chromosome goes to one cell, but rather a mixture of both the paternal and the maternal in this one chromosome go to one cell, and an opposite mixture goes to the other. And this is the third source of variation.
