Answer:
5. 100% of the F1 plants will have flowers with no dots.
Explanation:
When a gene is haploinsufficient, the wild type allele needs to be present in two copies to produce the phenotype. In heterozygous condition, the phenotype wont be produced even though one wild type allele is present. The product produced by single wild type allele is insufficient to produce the phenotype.
Here, gene A is haploinsufficient. Wild type allele A1 will produce flowers with dots when it is in two copies. Null allele A2 and mutant allele A3 wont produce flowers with dots. If a wild type (A1A1) is crossed with A2A3 :
A1 A1
A2 A1A2 A1A2
A3 A1A3 A1A3
Since all the plants in F1 progeny have only one wild type A1 allele, its product will be insufficient to produce dots pattern. 100% of the plants will have flowers with no dots.
Answer:
Through polymerization larger molecules are formed.

Polycythemia is defined an abnormal increase in the number of circulating red blood cells. It is mainly caused by a cancerous condition known as myeloproliferative disorder or due to a low supply of oxygen to body tissues usually due to living in high altitude areas and the body tries to compensate by producing more red blood cells to increase oxygen carrying capacity of the blood
Normal blood count values in a male adult is 4.7 to 6.1 million cells/mcL, while in a female adult it is 4.2 to 5.4 million cell/mcL.
If this blood cell count is significantly higher then these values, and remains there or continues to rise, over a given period of time, accompanied with some specific symptoms, then polycythemia is suspected.
Answer:
true. In science, sound is defined as the transfer of energy from a vibrating object in waves that travel through matter. All sound waves begin with vibrating matter. The vibrations generate longitudinal waves that travel through matter in all directions.
