<span>Aside from absorbing water and nutrients in the
ground, roots are also the very support of a tree. It supports bigger trees to
stand and stay steady against heavy rains and strong winds. Roots are also
capable of absorbing water that may cause flood in the area, and support slopes
that may result to landslides. Roots are very important because it lessen the
chances of soil erosion in a certain place. Roots can also be used for plant
vegetations.</span>
I would believe the correct responses would be option 1,2,4.
The correct answer is foot.
Mollusks have more diverse forms in comparison to any other animal phylum. They comprise, the slugs, snails, and other gastropods; squids and other cephalopods; clams and other bivalves; and other lesser known but identically different subgroups.
The cephalopods like octopuses and squids possess the head, which is prominent and the foot that has been amended into tentacles. The cephalopods have an absent or diminished shell and exhibit the most advanced nervous system of the invertebrates.
Use the Hardy Weinburg
equation of allelic frequency.
P2+2pq+q2=1
174/1378 = 0.126 = q2
Therefore q2 = 0.126; q = 0.355
If q = 0.355 and we understand that p + q = 1, then
P = 1 – 0.355 = 0.645
To find homozygous dominant population (p2);
(0.645)2 x 1378 = 0.416 x 1378 = 573
Heterozygous popualiton (2pq);
(2 x 0.645 x 0.355) x 1378 = 0.458 x 1378= 631
Recessive indviduals (q2) = 174
