Tems11 [23]3 years ago

Adaptive radiation is a process that occurs due to environmental changes and cause organisms to rapidly diversify from an ancestral species into a lot of new different forms. Simply saying, organisms evolve into a wide variety of new types that are adapted to new modes of life. For example, if certain animals from the same species, occupy different habitats with different environmental conditions, different morphological features or adaptations will be formed.

When mass extinction occurs, consequently number of species decrease and biodiversity is reduced. Many niches are left abundant, so they can be occupied by new species.

Butoxors [25]

Answer:

Option 3, Chromatids remain attached to one another until anaphase

Explanation:

Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.

svlad2 [7]

Answer:

Desert

Explanation:

A biome can be defined as a portion of the biosphere with distinct flora and fauna with respect to abiotic factors such as temperature, rainfall, topography, etc. They play important roles in the sustenance of life on earth.

The major types of biomes that exist in the world include:

  • Desert biomes
  • Tundra biomes
  • Aquatic biomes
  • Forest biomes
  • Grassland biomes

<em>The </em><em>desert biomes</em><em> are characterized by very little or no rainfalls with high temperature, low atmospheric moisture and low vegetation cover. Because of the high temperature and sun intensity, animals within deserts are mostly active at night in order to prevent desiccation.</em>

<em>Plants within the desert have also adopted some adaptive attributes in order to cope with the harsh conditions. These adaptations include having extensive roots that take in water quickly when available, possession of modified leaves to prevent excessive water loss due to evapotranspiration, etc.</em>

The biome being described in the question is desert.
