In the solid phase, molecules are closely packed together in a fixed position, vibrating in place. In the liquid phase, molecules are more loosely packed and have more freedom to move around, sliding past each other. In the gas phase, molecules are far apart and move freely and quickly, colliding with each other and the container walls.

What is important features in synthesis phase?
Synthesis phase or "S phase" occurs during the interphase of a cell cycle between the G1 and G2 stages. During synthesis phase, DNA molecules "unzip" and each old strand attracts free nucleotides forming complementary new strands, leaving two strands of DNA identical to the original strand of DNA.
When during the cell cycle is a cell's DNA copied?
DNA is copied during the S phase (Synthesis phase) of the cell cycle. This phase occurs between the G1 phase (Gap 1) and the G2 phase (Gap 2) in preparation for cell division. During the S phase, each chromosome is replicated, resulting in two sister chromatids for each chromosome, which will be separated during mitosis.
Will molecules go faster and farther when liquid turns to gas?
Yes, when a liquid turns into a gas, the molecules gain energy and move faster and farther apart from each other. This is because the intermolecular forces that hold the liquid molecules together are overcome as the energy input increases during the phase change.
If a body cell has 46 chromosomes during g1- how much DNA will be in the cells during s an g2?
During S phase, the DNA in the cell replicates, resulting in each cell having 92 chromosomes (since DNA replication is completed). During G2 phase, the cell still has 92 chromosomes, but each chromosome consists of two sister chromatids, so the total amount of DNA is the same as in S phase.
During what part of the mitosis process does the DAN replicate?
DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.
At the end of s phase each chromosome has how many coiled dna molecules?
At the end of S phase, each chromosome has two coiled DNA molecules, also known as sister chromatids. These sister chromatids are identical copies of each other formed during DNA replication in preparation for cell division.
Which phase of matter has negligible interactions between molecules?
The gas phase has negligible interactions between molecules compared to the liquid and solid phases. Gas molecules are far apart and move freely, rarely interacting with each other except during collisions.
Is energy required for each phase change?
Yes, energy is required for each phase change. During a phase change, such as melting, vaporization, or sublimation, energy is either absorbed or released in order to break or form intermolecular forces between molecules.
How do molecules behave during the solid liquid and gas phases?
When an object is solid, molecules get packed in a place. They cannot move freely. The force of attraction is great. So it gives the object a solid shape. When the object is liquid, molecules Move A little bit freely, so the force of attraction is less when the object is liquid. And when the object is gas, the molecules move very freely. They bump onto each other. The force of attraction is very very very less. That's why, gases move freely and go away.
How do people behave during Diwali?
People behave very nicely on Diwali. They greet each other.
DNA synthesis occurs?
during the S phase of the cell cycle, where the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand. Enzymes called DNA polymerases catalyze the formation of phosphodiester bonds between nucleotides to build the new DNA strand. The end result is two identical DNA molecules, each consisting of one original strand and one newly synthesized strand.
What is important features in synthesis phase?
Synthesis phase or "S phase" occurs during the interphase of a cell cycle between the G1 and G2 stages. During synthesis phase, DNA molecules "unzip" and each old strand attracts free nucleotides forming complementary new strands, leaving two strands of DNA identical to the original strand of DNA.
What is the phase of matter where molecules are most closely attracted to each other?
The phase of matter where molecules are most closely attracted to each other is the solid phase. In solids, molecules are tightly packed and held together by strong intermolecular forces, which restrict their movement and keep them in a fixed position.
Which phase has the most energy?
The phase with the most energy is the gas phase. Gas molecules have higher kinetic energy compared to solid or liquid molecules because they have more freedom to move and collide with each other at higher speeds.
Which particle diagram correctly represents propane in gas phase and liquid phase in a pressurized cylinder?
In the gas phase, propane molecules are represented as individual particles that are moving freely and far apart from each other. In the liquid phase, propane molecules are shown as closely packed together but still able to flow past each other.
What is the significance of the phase in physics and how does it impact the behavior of waves and particles?
In physics, the phase of a wave or particle refers to its position in its cycle. The phase is important because it determines how waves interact with each other and how particles behave. For example, when waves are in phase, they can reinforce each other and create a stronger signal. When waves are out of phase, they can cancel each other out. In particle physics, the phase can affect how particles interact with each other and with their environment. Overall, the phase is crucial in understanding the behavior of waves and particles in physics.
What occurs during the phase of the cell cycle?
A cell's DNA is copied during this phase. At the end of this phase, each chromosomes consists of two chromadtids attached at he centromere.
