The model of the cell cycle provides details about how cell division promotes genetic continuity, including DNA duplication, accurate segregation of chromosomes, and cytokinesis.
The model of the cell cycle provides several details that support the argument that cell division promotes genetic continuity:

b) very minimal
c) half of the reactant
d) all of the reactant
The Two substance that has low entropy are diamond and graphite while the other two chemical/substance that has high entropy are Noble gases(helium, neon, etc) and oxygen.
Generally, entropy measures the disorder or randomness in a system. High entropy implies randomness or high disorder while low entropy indicates orderliness.High entropy system, more energy is lost to the environment/surroundings.
Examples of chemicals or substances with high and low entropy are listed below
Low entropy
1.Diamond: This is a carbon crystalline substance. The makeup follows a well-structured pattern. The particles are tightly packed thereby giving them a low entropy value. This means they are well ordered.
2.Graphite: This is another carbon substance but they have higher entropy than diamond but generally possess a low entropy.
High entropy
Generally, gaseous substances possess high entropy, and this includes
1. Nobles gases(helium, argon, Neon, etc); These gases when placed in a closed system they exhibit high entropy. They act disorderly. They move randomly and tend to occupy every space available in the system.
2. Oxygen gas: This is another gaseous substance that exhibits disorderliness when placed in a closed system.
The arrangement of the particles and cohesive forces holding the individual particles of the substance together play a large role in determining its entropy.

Here are two examples:
Low entropy: -A carbon crystal structure at a temperature near absolute zero,
-A chunk of ice has low entropy
High entropy:- A box filled with two elements in their gaseous state, both of which are noble gases.
- Burning wood illustrates an increase in entropy heated very high temperature, with the gas "not very dense".
The entropy of a chemical system depends on its energy and its multiplicity, or how many different ways its atoms and molecules can be arranged. By adding new arrangements or energy, you increase entropy. A diamond, for example, has low entropy because the crystal structure fixes its atoms in place. If you smash the diamond, entropy increases because the original, single crystal becomes hundreds of tiny pieces that can be rearranged in many ways.
Burning wood illustrates an increase in entropy as The wood starts as a single, solid object. Fire consumes the wood, releasing energy along with carbon dioxide and water vapor, and leaving a pile of ashes. The atoms in the vapors and gases vibrate energetically, spreading out in an ever-expanding cloud. Dissolving salt in water is another example of increasing entropy; the salt begins as fixed crystals, and the water splits away the sodium and chlorine atoms in the salt into separate ions, moving freely with water molecules. A chunk of ice has low entropy because its molecules are frozen in place. Add heat energy and entropy increases. The ice turns to water, and its molecules agitate like popcorn in a popper.
The terrestrial planets represent characteristics of the four planets that are closest to the sun. Therefore, the correct option is A.
The solar system contains 4 planets that are closest to the sun. These planets are Mercury, Venus, Earth, and Mars. These planets are called terrestrial planets. Like Earth, these planets are rocky and have the same composition and structure. Hence, they are also called telluric planets.
Typically, these planets have a metallic core made primarily of iron and a silicate mantle. On their surface, they have topological characteristics like mountains, valleys, craters, etc.
Terrestrial planets have a secondary atmosphere, as opposed to large planets, which have a main atmosphere. It is well known that terrestrial planets have few or no satellites of their own. For instance, the Earth has just one satellite, but Mars has two, and Venus and Mercury both have none. Therefore, the correct option is A.

The question is incomplete, but most probably the complete question is,
Which of the following represents characteristics of the four planets closest to the sun?
1. Terrestrial planets
2. Giant planets
3. Dwarf planets
4. Gas planets
Answer:
they are hot or can get hot
2) At least one additional cell must also contain a count of 48.
3) The value of observed - expected for this cell = -2.
4) The progeny of this cross do not conform to a 1:1:1:1ratio.
Answer: The progeny of this cross do not conform to a 1:1:1:1 ratio
Explanation: This is because out of the 200 total resulting progeny, we must have 50 in each phenotype class to conform with the 1:1:1:1 which is not so as we have 48 in one of the phenotypic class already. Therefore, it did not conform to the ratio.
Answer:
The value of observed - expected for this cell = -2
Explanation:
"With a total of 200, the expected number in each cell when the predicted ratio is 1:1:1:1 = 50. The observed number is 48." - Mastering Genetics

Answer:
replication fork
Explanation:
The deoxyribonucleic acid (DNA) is a double-stranded helix composed of two long chains of nucleotides. The replication fork is a Y-shaped structure by which both DNA strands are separated in order to be replicated during cell division. In a cell, DNA replication starts at specific sites in the genome referred to as 'origins of replication'. A replication fork is generated by helicase enzymes that unwind and separate the DNA double helix strands by interrupting hydrogen bonds that hold the two DNA strands together. These DNA strands act as templates for the leading and lagging DNA strands. During DNA replication, the leading strand is synthesized continuously in the same direction as the replication fork, while the lagging DNA strand is synthesized in a direction away from the replication fork, in small pieces of DNA called Okazaki fragments.
