How could the origin of organisms such as dinosaurs, whose gait allowed them to move without compressing their lungs, have led to emergent properties?.
The ability of dinosaurs to move without compressing their lungs helped them to effectively produce more energy requited for other emergent properties.
What was the advantage of being able to breathe with lungs?The lung is a special organ in the body of higher animals such as mammals and birds whose function is for gaseous exchange.
Possession of the lung gave an evolutionary advantage to organisms that have lungs as it enabled them to occupy various habitats on land as they could effectively use oxygen to produce energy.
Therefore, the ability of organisms such as dinosaurs to move without compressing their lungs helped them to effectively produce energy for other emergent properties.

How does dna replication affect the number of chromosomes in the cell?.
Answer:
Following DNA replication, the DNA content doubles again to 4c, but each pair of sister chromatids is still counted as a single chromosome (a replicated chromosome), so the number of chromosomes remains unchanged at 2n.
Name the number of vertebrae that fuse together to form the sacrum.

7. ) Most of a cell's growth and activity occurs in the ______ phase.
a.) s phase
b.) m phase
c.) G0
d.) G2
e.) G1
Answer:
Interphase (A.K.A. S Phase)
Explanation:
Hope this helps.
Most of the cell's growth and activity occurs in the S-phase of mitosis. During the S-phase, a cell grows in size and genetic material duplicates. Thus, the correct option is A.
What is Mitosis?Mitosis is the division of cell in which the DNA or the genetic content of the cell remains constant from one generation to the next generation. Mitosis consists of interphase and M-phase. During the interphase, cell prepares for division while in the M-phase the cell undergoes division.
The S phase of a cell cycle occurs during the interphase after the G1 phase, before the M-phase, and it is responsible for the replication of DNA. In this stage, the genetic material of a cell is doubled before it enters the M-phase, allowing enough amount of DNA to be split into the two daughter cells.
Therefore, the correct option is A.

When does the mitotic spindle attach to the kinetichore?
Answer:
The Prometaphase.
Explanation:
Typically in biology the prometaphase is overlooked. It is between the prophase and the metaphase, and is the exact point in which the mitotic spindles attach to the kinetochores. Metaphase, which occurs directly afterwards, is when the chromosomes are lined up to be split and pulled towards opposite sides of the cell.

What causes folded mountains to form?
Collision of continental plates
Collision of a continental plate with an oceanic plate
Vertical shifting along a fault line
Lava emerging from a crack or fissure in the crust
Answer: Fold mountains occur near convergent or compressional plate boundaries. Plate movement creates fold mountains as the plates move towards each other. This movement causes layers of sedimentary rock on the ocean floor to become wrinkled and folded. These mountains are found between two continental plates.
