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.

mylen [45]

It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.

<h3>What is river and stream?</h3>

A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.

On the other hand, a stream is a small river or a body of moving water confined by banks.

Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.

Therefore, it is true that rivers and streams are biodiverse ecosystems that are sensitive to change.

rjkz [21]

Answer:

50%

Explanation:

Let's assume that the allele "T" gives the normal phenotype while the recessive allele "t" imparts the disease and is lethal in homozygous condition. The genotype of each of the two carrier parents would be "Tt". A cross between Tt and Tt would give the progeny in the following genotype ratio=

Tt x Tt= 1/4 TT: 1/2 Tt: 1/4 tt

Therefore, 1/2 or 50% progeny would be the carrier for the Tay-Sachs disease.
