Crab grass does so well when ordinary grass struggles in late summer
because its seed germination is higher when exposed to hotter
temperatures.
The seeds of crab grass are mostly dormant and their germination is
dependent on the soil temperature. During summer, the temperature of the
soil is usually higher which aids its growth .
This therefore explains the reason why crab grass does well than ordinary
grass in late summer periods.

Answer:
This is because the receptor is in the interior of the cell
Explanation:
When a specific signaling molecule is added to a cell whose cell surface has been stripped off by proteins the cell still responds because the receptor is in the interior of the cell.
Receptors are divided into two categories which are;
- Intracellular receptors or internal receptors which are found in the cytoplasm or nucleus of the cell. They respond to hydrophobic ligand molecules which are able to travel across the plasma membrane
- Cell surface receptors which are found in the plasma membrane
Signalling molecules are necessary for the coordination of cellular responses by serving as ligands and binding to cell receptors.
A type of signaling molecule are the small hydrophobic ligands which can directly diffuse through the plasma membrane and interact with internal receptors unlike the water soluble ligands. This is why the cell still responds after you strip off all proteins on the cell surface.
NOTE: Nitric oxide (NO) is a gas that also acts as a ligand, therefore it can pass through the plasma membrane of the cell and interact with receptors.
Answer:
Package the desired genetic material into a suitable plant virus and allow this modified virus to infect the plant. If the genetic material is DNA, it can recombine with the chromosomes to produce transformant cells.Explanation:
