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.
Approximately eighty seven percent of lung cancer deaths are caused by smoking.
Answer:
See the answer below
Explanation:
Let the tallness be represented by T and the shortness by t.
True-breeding tall plant = TT
True-breeding short plant = tt
<em> TT x tt</em>
<em> Tt Tt Tt TT</em>
<u>Genotypic ratio of offspring</u>: 100% Tt
<u>Phenotypic ratio of offspring</u>: 100% tall (see the first attached image for the Punnet's square analysis)
(a)<em> See the second attached image for the Punnet's square analysis</em>.
<em> Tt x Tt</em>
<em> TT Tt Tt tt</em>
<u>Expected genotypes</u>
<u>Expected phenotypes</u>
(b) <em> Tt x tt</em>
<em> Tt Tt tt tt</em>
<u>Expected genotypes</u>
<u>Expected phenotypes</u>
The kind of cross if referred to as<u> test crossing</u>.
(c) <em>Tt x TT</em>
<em> TT TT Tt Tt</em>
<u>Expected genotypes</u>
<u>Expected phenotypes</u>
