Well simply knowing that yellow hair colour is dominant to blue, Yellow Y hair allele will produce the functioning protein or pigment to product the yellow colour whereas the blue colour is only produced if both recessive alleles are present.
YY = yellow
Yy = Yellow
yy = blue
1) DNA condenses into
chromosomes. = prophase
2)Homologous pairs align
to initiate crossover. = metaphase
3) Microtubules pull apart the
homologous pairs toward
opposite poles. = anaphase
4) Nuclear envelopes develop
around the nuclei. = telophase
5) Cytoplasm pinches inward
near the cell furrow = cytokinesis
The immune system has many kinds of white blood cells to fight infections. HIV finds the white blood cells, called CD4 cells. But with cancer the white blood cells are being killed off.
<span>Chemical bonds hold atoms
together to form compounds. The answer is letter D. Chemical bonds may result
through the sharing of electrons as in covalent bonds or from the electrostatic
force of attraction between atoms with opposite charges as in ionic bond. There
are other bonds that exist to other compounds such as metallic bond and
hydrogen bonding. Also, the type of bonding will help us determine what will be
the phase of the compound. Just like in liquids, attractive forces are caused by
van der Waals bonds.</span>
