The is a source of stem cells that has the characteristics of self-renewal and limited differentiation.
kipiarov [429]

Answer:

<u>Amniotic fluid</u>

Explanation:

Amniotic fluid found in the uterus is capable of forming different types of cells thus said to be self-renewal. However the cells have limited differentiation but when grown in conducive conditions in the lab, the cells can form different tissues like bones, liver, muscle cells and brain.

The amniotic fluid suspends the foetus allowing it to grow and move freely. It also protects the foetus from damage by any pressures acting on the mother's womb.

Lelechka [254]

The following are the expected ranks of biomes  based on increased oxygen for plant growth and they are

1. Desert,

2. Grassland

3.  Temperate Forest

4. Tropical Rain Forest

The desert biome is formed owing to very limited annual rainfall and it covers approximately 20% of the Earth.  The Grassland is predominantly dominated by grasses while the temperature in the temperate forest is around 10 degree celcius. The plants and trees in this biomes develop special adaptations for their survival. However, the rain forest is characterized with all year round rain hence the biome is moist. The biome is known for vegetations with dense canopies.

Doss [256]

Answer:

Explanation:

A mutation is any alteration in the genetic material of an organism. In general, mutations have a negative impact on the fitness (or reproductive success) of the individual that carries this mutation; however, there are situations where a mutation may be beneficial for the individual in a given environment. When a beneficial mutation occurs in the germline, it potentially can be passed to the next generation and progressively increases its frequency in the population.
