Answer: The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species.
Explanation:
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.
The reverse of deposition issublimation and hence sometimesdeposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.
