Answer:
Genetic variation among plant populations often occurs along different climatic gradients, such as temperature and precipitation gradients.
Environmental factors are often responsible for the patterns of genetic structure observed at small spatial scales (Sacks, Brown, & Ernest, 2004).
Answer No 1:
During the interphase, the genetic material is copied so that each daughter cell can receive equal and right amount of genetic material. The right amount of the genetic material is a crucial step for every daughter cell to survive.
Answer No 2:
Embryonic stem cells have the ability to convert into any type of cell type. Specialized cell types can make specialized cells. Scientists are working on producing stem cells which can cure various diseases like paralysis or brain damaged cell.
Answer No 3:
By the process of meiosis, the number of chromosomes is reduced to half in the sex cells. When an egg cells and the sperm cell unite in the process of fertilization, the number of chromosomes become diploid again. Hence, the number of chromosomes gets maintained in the embryo in this way.
Answer:
The plateau region has endemic population of species and the change in the ecology impacts the climate and wildlife of the area.
Explanation:
- The Edwards plateau is located in the south, central and western taxes. It bounded by faults and uplands. It has a base made of limestone.
- The plateau is home to various diverse species of plants and animals. The plateau region consists of 41 counties in geographic regions. Currently, about 2.26% of the land area is under protection as this region has experienced habitat loss of 5.3%.
