The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
The percentage of alleles for homozygous recessive would be 50%
A because osmosis will act to balance the concentrations of water inside and outside the cell. As this happens, sugar outside the cell will dissolve into the water and be moved across the cell membrane with it into the cell. This continues until the concentrations are equal.
A(n) shark is an example of an organism that can sometimes reproduce asexually by parthenogenesis.
<h3>What is parthenogenesis?</h3>
Parthenogenesis is defined as a special type of asexual reproduction in living organisms which involves the development of female gametes without any fertilization.
However too parthenogenesis occurs in some plants.
There are three different forms of parthenogenesis; these are:
- Arrhenotoky
- Thelytoky
- Deuterotoky.
In conclusion, shark is an example of an organism that can sometimes reproduce asexually by parthenogenesis.
