The probability of progenies to have red flower is 50%.
<h3><u>Explanation:</u></h3>
The phenomenon where the two pure alleles of a particular character present in an individual gives a mixed appearance is called incomplete dominance, where the dominant character cannot fully mask the presence of a recessive character.
Here In the cross between a red flowering plant and the pink flowering plant, the character shows the incomplete dominance.
Let the allele for dominant character i.e red flower be R and recessive character white be r.
So the genotype for red flowering plant = RR.
The genotype for pink flowering plant =Rr.
The gametes from red flowering plant =R.
The gametes from pink flowering plant =R and r.
So with the cross, the genotype of the offsprings will be 50% RR and 50% Rr.
So plants with red flowers will be 50% of the whole progeny.
The awnser is true

Answer:
Grasshopper has open circulatory system.
Explanation:
Grasshopper has open circulatory system and they have a fluid cavities called haemolymph. Grasshopper have open circulatory system because the blood is not usually in the blood vessels. The hearts like structure pump the blood into the aorta and the blood flow from aorta in the body fluid, called haemolymph. The heart like structure is located in the upper part of the abdomen and pump fluid to the head and passes through organs and tissues.
the main property is flammability
