The answer is Procrastinating
Work ethics ,working at a steady rate and personal goals will help with control, organization and consistency which will all reduce stress
Procrastinating builds up work until last minute which will give the most stress
In the block to polyspermy, entry of the sperm's contents causes calcium ion levels in the oocyte's cytoplasm to rise, triggering the cortical reaction.
In biology, polyspermy describes the fertilization of an egg by more than one sperm. Diploid organisms normally contain two copies of each chromosome, one from each parent.
The cell resulting from polyspermy, on the other hand, contains three or more copies of each chromosome—one from the egg and one each from multiple sperm. Usually, the result is an unviable zygote. This may occur because sperm are too efficient at reaching and fertilizing eggs due to the selective pressures of sperm competition.
The cortical reaction is a calcium-dependent exocytotic process in which the content of secretory granules is released into the perivitellin space immediately after fertilization, which serves to prevent polyspermic fertilization.

The ends of the actin filaments are anchored to the Z-line or disk.
The sarcomere is the primary functional unit of muscle fiber. It is flanked by a Z-band on each end with adjoining I-bands. The Z-band or disk is a dense fibrous structure composed of actin, α-actinin as well as other proteins.
Thin filaments or actin filaments are anchored at one end at the Z-band. Titin is connected to both the Z-band and the M-line. Thick filaments are attached in the middle of the sarcomere at the M-line.
An intermediary filament protein forms a meshwork from one Z-disk to the next across the myofibril. These networks are joined by actin through the protein dystrophin to the sarcolemma.

Answer:
Karyotype
Explanation:
A karyotype is a picture of all the chromosomes in an individual. These images are analyzed by geneticists to identify structural changes in the chromosomes or to identify differences in number as is the case for Down syndrome.
Karyotyping is used to identify certain genetic diseases associated with chromosomal aberrations. This is associated with the field of cytogenetics.
