Explanation:

The evolution of bacteria has progressed over billions of years since the Precambrian time with their first major divergence from the archaeal/eukaryotic lineage roughly 3.2-3.5 billion years ago. This was discovered through gene sequencing of bacterial nucleoids to reconstruct their phylogeny.

Cell biologist, Dr. Martine Dinen, is observing an organism's cell using a transmitting electron microscope. She notices that wi
Assoli18 [71]

The cell is most likely prokaryotic because:

Prokaryotes lack membrane-bound organelles such as the nucleus due to which the DNA are seen throughout the cytoplasm.

Eukaryotes have membrane-bound organelles such as the nucleus. So for eukaryotes, the DNA will be present packed inside the nucleus instead of being dispersed in the cytoplasm.

Prokaryotes can either be autotrophic or heterotrophic depending on their mode of nutrition. Autotrophic prokaryotes can make organic molecules for a carbon dioxide source. On the other hand, heterotrophic prokaryotes can take carbon from organic compounds. Hence, the organism can be autotrophic or heterotrophic.

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.
