The answer to this question would be: <span>b.electromagnetic or weak nuclear
</span>
The electromagnetic force can be repulsive or attractive because it was influenced by the magnetic charge. The same charge (positive with positive) will be repulsive but different charge will be attractive(negative and negative). The gravitational force will always be attractive, not repulsive.
Weak nuclear can do both like electromagnetic force.
Answer:
As insect nymphs grow larger, their exoskeleton becomes too tight and they must replace it. Once a nymph outgrows its exoskeleton it will go through a process called molting, in which it leaves the old “skin” or exoskeleton behind. The new “skin” will harden and become the new exoskeleton
Explanation:
The right answer is Haploid cells join to form an organism that has a complete set of chromosomes.
Meiosis makes it possible to pass from a cell to 2n chromosomes to 4 cells with n chromosomes, thus ensuring the passage from the diploid phase to the haploid phase.
So from the fertilization phase to the meiosis phase, the cells will be diploid (2n chromosomes). From the meiosis phase to the fertilization phase, it is the haploid phase (n chromosome).
