Answer:
The root system is always adventitious. The stem is either underground or aerial. The leaves may be microphylls or megaphylls. Their other common characteristics include vascular plant apomorphies (e.g., vascular tissue) and land plant plesiomorphies (e.g., spore dispersal and the absence of seeds).
Explanation:
The practice of leaving crop residues on the field in between planting seasons is known as conservation tillage.
<h3>Conservation tillage</h3>
Some soils are prone to erosion once they are directly exposed to the impact of precipitation.
After harvesting crops from a field, the crop residues are left on the field to prevent the direct impact of precipitation in cause erosion. The crop residue, in addition, adds to the organic matter of the soil after their decomposition.
Such a practice is known as conservation tillage.

Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.
As mentioned in the question, wavy hair is a result of phenomenon of incomplete dominance where no allele is dominant over the other.
So if we say a man with curly hair (hh) marries a woman with straight hair (HH), we need to find out will their kids have straight hair or not.
Let us cross them:
Parents: hh X HH
Gametes: h : h and H :H
Offspring: hh: Hh: hH: HH
Probability of children with straight hair (HH) = 25 %
Probability of children with curly hair (hh) = 25%
Probability of children with wavy hair = 50 %
So there is a chance of 25 % that their kids can have straight hair.
Hope it helps!
Analogous structures are structures with different evolutionary ancestries but they have the same function. Examples include; wings of birds, insects and bats. On the other hand homologous structures have similar ancestries and common traits but may not have the same function in an organism. Well; in the above question Human apes have five fingers they can use to grasp objects, which i think these are homologous structures.
