<u>Answer:</u>
<em>Movement will be brought about in touch me not plants by the action of various chemicals present at the base of the leaf stalk.
</em>
<u>Explanation:</u>
<em>The leaves of touch me not plant stay upright due to turgor pressure. </em>It is exerted by the water present within its cells. This pressure applies force against the cell wall enabling the plant to remain stiff.
When there is an external disturbance , parts of the plant releases certain chemicals including potassium ions that causes water to diffuse out of cells. <em>This releases the turgor pressure and causes the leaves to shrink. </em>
Answer:
Explanation:
Long-term Self-Renewal: Stem cells are capable of division while remaining unspecialized.
Differentiation
: Stem cells can divide asymmetrically, where one stem cell divides into two cells that have different cellular fates.
Induced Pluripotency
: Stem cells that have been artificially created from specialized cells are called induced pluripotent stem cells.
Considerations
: Due to their unspecialized nature, stem cells have a large research potential. The most pluripotent stem cells derive from the human embryo.
<h2>Answer:</h2>
Bt corn is a genetically modified organism that contains a gene of bacteria known as Bacillus thuringiensis.
<h3>Explanation:</h3>
- Bt corn is a type of transgenic crop that contains a gene which produces a crystal-like protein which has an insecticidal effect.
- This gene is present in bacteria. This gene is transferred to the plant by the recombinant DNA technology and genetic engineering.
- This bacterium is a soil bacterium which has no side effects on humans.
- Due to use of this technology, the poisonous chemical insecticides are not used in crop production.
It’s is letter B because in every other state they do not use uranium
