Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring.
Explanation:
a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring.
Answer:
The UN projects that the global population increases from a population of 7.7 billion in 2019 to 10.9 billion by the end of the century. By that time, the UN projects, fast global population growth will come to an end.
Beneath the global level, there are of course, big differences between different world regions and countries. While in some regions the world population will likely grow rapidly for the coming decades other regions will continue to see declining population numbers.
Global population growth is determined by the number of births and deaths. Improving health is increasing the size of the population as it is decreasing mortality. The countervailing trend are falling fertility rates – the trend of couples having fewer children is what brought rapid population growth to an end in many countries already, and what will bring an end to rapid population growth globally.
The global population growth rate has already slowed down considerably: It reached its peak at over 2% in the late 1960s and has been falling since.
The UN projections for the global population growth rates, which have been produced since the 1950s, have a good track record in projecting the size of the global population.
While the UN projections are most widely know there are other very carefully produced projections. The demographers of WC-IIASA model what will happen according to different scenarios and make clear that the population growth rate tomorrow depends on what we do today. Rapid progress in getting children and especially girls into schools will result in a much smaller global population.
The biggest disagreement between different projections is concerning the future of Africa. While the UN projects a 3.5-fold increase of the population of Africa, other researchers find a much smaller increase more likely.

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.
