Answer:
Unlike a steady pattern of growth, arthropods exhibit an external growth that proceeds in a sequence of step-like jumps, as the organism builds and replaces its exoskeleton. The arthropod does not grow bigger in size between these jumps. An aquatic arthropod gradually replaces body mass for water detained inside the tissues between molts.
Answer:
The correct answer is the third statement.
Explanation:
In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.
When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.
