Answer:
Actin filaments return to their original positions (does not occur in muscle contraction, according to the sliding filament model).
Explanation:
Prophase I
The chromosomes condense, and the nuclear envelope breaks down & crossing-over occurs.
Metaphase I
Pairs of homologous chromosomes move to the equator of the cell.
Anaphase I
Homologous chrmosomes move to the oppisite poles of the cell.
Telophase I and Cytokinesis
Chromosomes gather at the poles of the cells & the cytoplasm divides.
Prophase II
A new spidle forms around the chromosomes.
Metaphase II
Chromosomes line up at the equator.
Anaphase II
Centromeres divides & chromatids move to the opposite poles of the cells.
Telophase II and Cytokinesis
A nuclear envelope forms around each set of chromosomes & the cytoplasm divides.
The worm would be unable to burrow and dig through the soil.
Chaetae are involved in the locomotion of the worm by giving the worm grip and <span>tools</span> to burrow <span>through</span>
the soil. <span> </span>Chaetae <span>are</span> made of chitin project from the body wall <span>on</span> each segment are arranged in 4 pairs and are
sited on the ventral surface - two pairs of ventral chaetae are found just
either side of the midventral line and two pairs are further out in the
ventrolateral position (that is just ventral of the side of the worm).
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly. As the temperature increases, transpiration will increase due to a higher concentration in sunlight and warm air. However, if temperatures remain high for long periods of time eventually leading to drought, transpiration may go down to conserve water in the plant.
