Answer:
Crossing over is a process in which exchange of segments occur between two non sister chromatids.
Explanation:
Crossing over is a process in which two non-sister chromatids of homologous chromosomes exchange the segments of genetic material with each other during meiosis. Due to this process, variation occurs in an organism.
Independent assortment is a process in which different alleles are sorted to different gametes which occurs independently and does not effect one another. This process occurs in metaphase of meiosis l.
Joining of sex cells is a process in which sex cells of male and female join together formed a zygote which turn into a new organism. These sex cells are formed during meiosis which are haploid in nature.
Mutation and crossing over are the factors that cause inherited genetic variations within populations.
Sudden change occurs in the genes of an organism due to the exposure of the cell to radiation or chemicals.

Explanation:
Mr. Heath organizes a six-game tournament where players will
• earn 2.2 points for every game won (W),
• earn 14 point for any game ending in a tie (T), and
• lose 3 points for every game lost (L).
Tally a score for an imaginary player.
Make sure the player plays all six games and has at least one win, one loss, and one tie.
Write and solve an equation to find the player’s total score.
Between rivers or streams, and the dry land are areas covered by lush vegetation called the "riparian zone". These consists of shrubs, grass, and small trees. This area is highly productive due to its close proximity to a water source, as compared to the areas found farther from the rivers. The riparian zone is a terrestrial biome.
A group of similar cells that perform a single function is called a tissue.
