Answer:
a. all tall
Explanation:
If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.
Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent who is heterozygous will be Tt.
The cross is depicted in the attachment.
Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.

Chloroplasts are the food producers of the cell.
<u>Answer:</u>
<em>Several factors have to be considered while planting green roofs.
</em>
<u>Explanation:</u>
<em>Green roof is a roof with vegetation growing in it. The vegetation is usually grown above a waterproof cover.</em> Many factors have to be considered while installing a green roof.
First is <em>sunlight availability</em>. While installing green roofs it has to be ensured that its location has adequate sunlight availability. If not the plants that require less sunlight must be chosen. The roof should be <em>flat or have low inclination.</em> The maximum allowable inclination is 30 degree.
The choice of plants has to be made according to the climate of the region. <em>The dry or wet nature of the region’s weather decides the type of plants grown there. </em>
Answer:
Extensive damage to oligodendrocytes in the cns could result in l<u>oss of sensation and motor control.</u>
Explanation:
Oligodendrocytes are presnt in glial cells of Central nervous System which comprises of Brain and spinal cord.They are related to the nerve cells. It provides support by production of glial cell line derived neutrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) or insulin growth factor IGF-1 they reduce ion leakage and decrease the capacitance of the cell membrane. Due to intensive damage of the Oligodendrocytes the motor nerves and other nerves of CNS damages looses it activity.
These are mainly occurred due to peripheral injury or demylinated diseases like multiple sclerosis, leukodystrophies,cerebral plasy and other congential disorders.Some chemicals like fluorouracil causes damage to the oligodendrocytes.
