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:
<h2>
<em><u> Parenchyma simple tissues: </u></em></h2>
<em><u>Cells of parenchyma tissues live. They are oval, elongated and loosely packed with large inter-cellular space, forming basic packing of tissue and found throughout the plant body. Functions of parenchyma: They provide mechanical support to the plant body. They store food and nutrients in vacuoles.</u></em>
<h2><em><u>Collenchyma simple Tissues</u></em>: </h2>
<em><u>Cells of collenchyma are live. They are oval and elongated and tighily packed with no inter-cellular spaces. They epidermis in leaves and stem. Functions of collenchymas tissues: They provides mechanical support to plant. They also provide flexibility to plants so that they can bend without breaking.</u></em>

Answer:
In summary, enzymes are proteins that lower the activation energy of a chemical reaction. Enzymes are not consumed or produced in a reaction, but they are catalysts that allow the reaction to proceed at a faster rate. ... Together, they form the enzyme-substrate complex.
