As hinted in the question, the cross bridge cycle is a
series of molecular events that occur after excitation of the sarcolemma. A
cross bridge is formed when a myosin head bound to actin. The cross bridge
cycle depends on the presence of calcium ions
The repeating stages a cell experiences, including cell division, compose the cell cycle.
Life cycle of the cell (cell cycle) can be divided in interphase and mitotic phase.
Interphase can be subdivided into:
• G1 phase characterized by the growth of the cell
• S where DNA replication occur
• G2 phase final preparation for mitosis.
Mitotic or M phase consists of:
• Prophase-condensation of chromosomes and mitotic spindle formation
• Metaphase-alignment of the chromosomes
• Anaphase- Sister chromatids are pulled apart by the mitotic spindle
• Telophase-each pole of the cell contain full set of chromosomes.
Two new cells are formed after cytokinesis.

Answer:
Yellow seed colour (heterozygous)
Explanation:
Since we are performing experiment on the garden pea, so in the garden pea Yellow seed color is dominant and green one is recessive.
The allele responsible for the seed colour is denoted by Y.
So,
Homozygous parent having Yellow seeds will have allelic configuration as YY and the other homozygous parent with green seeds will have yy as pair of alleles.
In the cross of YY × yy the F1 progeny will be Yy which means F1 offspring will will be heterozygous and have Yellow seed colour because Yellow seed colour is dominant over the green colour. Green colour will express itself only in the homozygous condition.
Diffusion, osmosis, or active transport.
