1.The Punnett square above shows a cross between two sweet pea plants in Mendel's

jenyasd209 [6]

1) 75% purple flowered and 25% white flowered. If you complete the punnett square, you'll see the combinations are PP, Pp, Pp, and pp. The capital P is dominant (purple), so you know that 3/4 combinations will be purple flowers.

2) 50%. There is a 50% chance Grace will have Huntington's disease because since the disease is dominant, it is capital letter H. When you make a punnett square, you'll see the combinations are Hh, Hh, hh, and hh. There is a 50% chance Grace will have the Hh combination.

3) Protein. Protein is the only bio-molecule out of the 4 options, and the diagram shows a protein being made.

4) Transcription. Transcription is when the genetic message from DNA is transcripted onto mRNA.

Complete question:

Several structures work together to allow flowering plants to reproduce. The diagram shows a typical flower.

Which answer correctly identifies the function of each structure or group of structures in the reproduction of the plant?

X- pollen production

Y- pollen transfer

Z- production of eggs

X- attraction of pollinators

Y- production of male sex cells

Z- egg production

X- production of eggs

Y- pollen transfer

Z- pollen production

X- production of eggs

Y- pollen production

Z- pollen transfer

Answer:

X- attraction of pollinators

Y- production of male sex cells

Z- egg production

Explanation:

Flowers are reproductive structures in charge of sexual reproduction through the production of seeds.

Z, Feminine reproductive structures:

The central structure is known as a carpel, also recognized as the pistil.
The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.
The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.
The ovary and the stigma are connected by a filament named style.

Y, Masculine reproductive structures:

The pollen grains, or male sex cells, are produced in the stamens.
The stamen has an anther where the pollen is produced, and a filament that provides support.

When mature, pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick. Once in the stigma, the pollen grains move to the ovary, where they meet the egg and fertilize. The zygote develops in the ovary.

X, External non-reproductive structures:

Flowers also have external structures known as petals and sepals. These structures are modified leaves whose principal function is to protect the flower´s fertile parts and attract pollinators. Petals characterize as having many different colors that make the flower more attractive to insects and some animals. When they visit a flower searching for their recompense, the flower´s pollen grains transfer to the insect´s body. The insect transports the pollen to the next visited flower, leaving it in the stigma of the second flower.
