Answer:
<em>Chromosomes compress, thicken, shorten, and become more apparent during prophase. At the centromere, chromosomes appear as two sister chromatids fused together. Chromosomes line up on the equator during metaphase.</em>
Answer:
1. Tundra Biome, 2. Rainforest Biome, 3. Grassland Biome, 4. Taiga Biome, 5. Desert Biome, 6. Deciduous Forest Biome.
Explanation:
1. Tundra is known for arctic conditions, lying north of Taiga biome. There are large ranges in most climatic conditions here.
2. Found around the equator, variety of tropical animals and plants.
3. Vegetation is mostly grass, very flat land thus good for farming.
4. Also known as the Boreal forest biome. Much vegetation.
5. High evaporation rate, animals adapted to dry conditions.
6. Cold winters and warm summers, thus winter makes growing deciduous.
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.
