In parthenogenetic reproduction, the egg cell develops into a new or ganism without fertilization. It is clear that the most essential feature of parthenogenesis, absence of fertilization, causes important alterations of basic nature in cytological, as well as in genetic, respects.

Complete question:
You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply
- The swing will move farther away from the tree trunk.
- The swing will move up. away from the ground.
- The swing will remain in its original position.
- The swing's ropes will become embedded in the branch.
Answer:
The swing's ropes will become embedded in the branch.
Explanation:
The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.
Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:
- The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normally
or
- The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.
<em>In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch. </em>
Triglycerides and cholesteryl esters are transported in the core of plasma lipoproteins. The intestine secretes dietary fat in chylomicrons, lipoproteins that transport triglyceride to tissues for storage. Dietary cholesterol is transported to the liver by chylomicron remnants which are formed from chylomicrons.
