Correct answer:
"<span>B- homologous chromosomes join together to form tetrads during prophase I"
</span>It is during prophase I that homologous chromosomes join together (<span>synapsis)</span> and form tetrads - four chromatids are together in the new structure of two chromosomes - and this is the reason why crossing-over occurs in this phase. It is in this tetrad that both arms of both chromosomes may crossover and matching regions exchange places. This process results in homologous chromosomes recombination leading to genetic variability.
Answer:
f
Explanation:
It is variation because not all individuals are the same, and this may be due to the genetics they have
<span>Nickel and cobalt are ferromagnets. This means that they are able to acquire magnetism from induction by an external magnetic field. This is caused by the realignment of atoms and unpaired electrons in their structure induced by the magnetic field. Aluminum and copper don't get magnetized because they have few unpaired electrons in their atomic structures. </span>
