The cuticle decreases water loss and stomata assist gas exchange. The plants from wet habitats must have a comparatively large number of stomata and thin cuticle. The plants existing in dry habitats must have comparatively few stomata and thick cuticle.
We know that fertilizier could promote the growth of the plant
When washed to the river, it will accelerate the growth of the water plant that exist within that area,
This occurrence will be not beneficial to the water animal because their habitat will be unnaturally blocked by these plants
hope this helps

Answer:
The CFTR behaves like a channel for chlorine. Its dysfunction affects both the transport of this ion and other ions and the transport of water, which causes a thickening of secretions, an alteration of mucociliary transport and local defenses, facilitating bacterial colonization and promoting the release of pro-inflammatory mediators in the airway
Explanation:
CFTR is a protein expressed in the epithelial cells of the respiratory system, pancreas, bile ducts, sweat glands and genitourinary system. It is made up of a single chain made up of 1,480 amino acids. It contains 12 hydrophobic regions embedded in the lipid membrane and acts as a channel for chlorine.The highest levels of expression of the CFTR protein are found in serous cells of the submucosal glands of the proximal airway. In them, Cl- is released to the outside. In addition, there are channels for Na +, through which this ion is also secreted in the same direction. These movements cause the displacement of water and also of mucins, originating in the submucosal glands, allowing their presence on the surface of the airway. For all this to occur normally, a basolateral Na + - K + - ATPase cotransporter must function, another basolateral cotransporter formed by Na +, K + and 2 Cl-, which allows the latter to enter the cell, and an apical CFTR channel through which it exits the Cl- of the cell towards the acinar lumen. Na + leaves the cell following Cl- by a paracellular pathway accompanied by water. When CFTR malfunctions, Cl- does not exit through this channel and this implies a decrease in Na + and water in the canalicular lumen, with the consequent thickening of secretions.
Answer:
Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance
Explanation:
Let the allele for floppy ears be "F" and the allele for straight ears be "f"
And Let the allele for black coat color be "B" and the color for white coat color be "b"
Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)
The 16 offspring have genotype FfBb
Phenotype of 16 offspring is Floppy ears and grey coat
Ff represents the floppy ear , thus "F" is dominant over "f"
Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.
Hence, option E is correct
