The Aleutian Trench is formed by the subduction of the Pacific Plate underneath the North American Plate along the coastline of Alaska. What would most likely be
observed at this tectonic boundary? (3 points)
1) Chasms reaching the mantle are caused by two tectonic plates moving away
from each other
2) Creation of new seafloor formed from the solidification of magma between
the plates
3) Explosions underneath the Earth's crust caused by the collision between two
tectonic plates
4) Frequent earthquake activity caused by the movement of tectonic plates
against each other

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).
