Answer:
In biology, heterozygous means that the two alleles of a gene will be different. Homozygous means that the two alleles of a gene are similar.
A cross between to heterozygous parents for genes (Ww) is shown below:
W w
W WW Ww
w Ww ww
The results show that 25% of the population will be homozygous dominant, 50% of the population will be heterozygous dominant, 25% of the population will be recessive for the trait.

Features that will form near convergent oceanic plate boundary is a trench & volcanic arc
Explanation:
A trench is formed because at the boundary where the two tectonic plates are colliding, there so much stress such that the two plates warp downwards and form a depression all along the boundary. This is a mid-ocean trench. This is as opposed to a mid-ocean ridge that forms at a divergent boundary.
A volcanic arc – a chain of volcanic mountains along the convergent boundary –is formed because the enormous stress along the boundary causes the formation of fissures. The subdued plate, as it dives into the mantle, melts into magma that rises through these fissures. At the surface, the magma erupts violently into a volcanic mountain. Because there are many fissures along the boundary, several volcanic mountain chains will form along the boundary.

After the delivery of her child, the mother went to the postpartum unit of the hospital
The postpartum unit of a hospital is the area where babies (new born) and their moms recover after birth. In the postpartum unit the neonatal nurse specialist focus on the care of newborn infant. The nurses focuses their care for premature or ill newborns.
Answer:
• oxygen
• nitrogen
• carbon
Explanation:
Electronegativity is a scale that measures an atom's attraction towards an electron. The more electronegative an atom is, the more it attracts an electron. Electronegativity increases as we go up and from left to right in the periodic table.
Hence, the following elements are considered to have a high level of attraction for surrounding electrons
• oxygen
• nitrogen
• carbon
