In the PCR cycle, nucleotides are used during the 'Extension' or 'Elongation' phase. DNA polymerase adds nucleotides to the DNA strand at the primer site, resulting in two identical copies of the original DNA strand. The use of nucleotides is the key aspect of this phase of DNA replication.

In the Polymerase Chain Reaction (PCR) cycle, nucleotides are used during the third step, known as the 'Extension' or 'Elongation' phase. During this step, the DNA polymerase enzyme adds free nucleotides to the DNA strand at the primer site. This process of adding nucleotides to a DNA strand in a sequence that matches the original DNA strand results in two identical copies of the original DNA strand.

The PCR process has three main stages: Initial denaturation, Annealing, and Extension. The Extension stage is where the nucleotides come into play. Here, the DNA is 'built' by adding nucleotides in a sequence dictated by the original DNA strand. It's a key part of the DNA replication process.

Answer:

Mineral's interior atomic structure

Explanation:

The interior atomic structure of a mineral refers to the system of arrangement and orientation of the atoms within the crystals. They are made up of fundamental unit cells and continue their arrangement periodically in a three-dimensional system.

There is a total of six crystallographic systems and they all have their own characteristics for identification. They are as follows-

1) Isometric system

2) Orthogonal system

3) Monoclinic system

4) Triclinic system

5) Orthorhombic system

6) Tetragonal system

The study of the arrangement of these atomic crystal plays an important role in the field of mineralogy and further, by observing these structures, a mineralogist can determine to which crystallographic system a mineral belongs.

The characteristics of soil profiles are significantly influenced by topography, which affects water runoff, erosion levels, soil fertility, and plant growth. Other factors like climate, organisms, parent material, and time also contribute to soil development.

Soil Profile Characteristics and Topography

The characteristics of soil profiles are closely linked to several key factors, with topography being one of the major influences. Regional surface features, or the lay of the land, play a significant role in the development of soils. Topography determines water runoff, which can erode or strip away the parent material leading to variances in soil fertility and structure. This process can make steep soils prone to erosion and generally thinner as opposed to flatter, more level soils. Additionally, topography affects plant growth and can limit water infiltration in steeper regions, further distinguishing the characteristics of different soil profiles.

Beyond topography, the other factors that influence soil development include the mineralogy of the parent material, the local climate, the amount and type of organisms present, and the amount of time these factors have influenced the soil. Each of these contributes to the unique nature of a soil profile.

Fish have adaptable behaviors and structures so that they can survive in the wild. These adaptations however differ with regards to context and environment. Some fishes for example are called stonefish because they can camouflage in environments that are composed variedly with pebbles and rocks, and this helps them to avoid predators and thrive. Nevertheless, when these group of organisms are strayed and become exposed to a new environment they can be exposed and be vulnerable to predators. 

Answer:

Some fish have spots on their tail to trick other fish that that is their eye because fish cant swim back wards so predator fish attack from the front so they cant get away. The pray fish will then be able to get away because the can swim forwards to get away from the predator. Puffer fish their defence is blowing up in a spikey ball and so first the predator might not be able to get them in their mouth and if they were able it would be painful so hopefully the predator would leave them alone.

Final answer:

Osmosis and diffusion are vital to cellular processes, with osmosis being a subset of diffusion that specifically involves the movement of water across a semi-permeable membrane to balance solute concentrations.

Explanation:

Diffusion and osmosis are both processes vital to cell function and share a similar mechanism in that they allow substances to move from areas of high concentration to areas of low concentration. The key difference is that osmosis specifically refers to the movement of water through a semi-permeable membrane and is influenced by the concentration of solutes in the water. During osmosis, water moves to equalize solute concentrations on both sides of the membrane, often facilitated by proteins called aquaporins.

Diffusion happens in both living and nonliving systems and can involve various substances, including gases and small uncharged molecules. For example, oxygen and carbon dioxide use simple diffusion to move into and out of cells. On the other hand, osmotic pressure is demonstrated when cells are immersed in sugar solutions, causing water to move across the cell membrane to achieve balance.

Osmosis is crucial for maintaining cellular integrity and adapting to changes in solute composition outside the cell. In medical treatments, such as when soaking a swollen ankle in Epsom salt, controlled osmosis can also have therapeutic effects. Both diffusion and osmosis are forms of passive transport, which means they do not require energy to occur.

Final answer:

Osmosis is the diffusion of water molecules across a membrane due to differences in concentration.

Explanation:

Osmosis is the diffusion of water molecules across a membrane due to differences in concentration. It is a specific type of diffusion that allows water to move from an area of high water concentration to an area of low water concentration. This movement occurs through a semi-permeable membrane, which only allows certain substances to pass through.

Mechanism of action for nitroprusside is it directly relaxes vascular smooth muscle, allowing dilation of peripheral arteries and veins.

Sodium nitroprusside, sold under the brand name Nitropress among others, is a medication used to lower blood pressure. This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding.

Sodium nitroprusside injection is used for lowering of blood pressure immediately in adults and children with high blood pressure. This medicine is also used to reduce bleeding during surgery, and treats acute heart failure.

Sodium nitroprusside is a water-soluble salt comprised of ferrous iron complexed with nitric oxide (NO) and five cyanide ions. Acting as a prodrug, SNP reacts with sulfhydryl groups on erythrocytes to produce nitric oxide.

Sunlight does not directly cause erosion but can indirectly influence processes that contribute to it. Ice, rain, and wind are direct causes of erosion.

The question is about what factors directly cause erosion. Erosion involves the wearing away of earth's surface through various means. The options given are ice, rain, wind, and sunlight. Of these, ice through the process of glaciation, rain through water erosion, and wind through deflation and abrasion can directly cause erosion. However, sunlight does not directly cause erosion; instead, it can indirectly contribute to erosion by affecting temperature and thus influencing other erosion processes, like thermal expansion of rocks leading to physical weathering.

Spicules are sharp, spike-like structures found in sponges, primarily composed of calcium carbonate or silicon dioxide. They serve two main functions: providing the sponge with structural support and deterring predators due to their sharp and indigestible nature.

Spicules are small, sharp, spike-like structures found in organisms such as sponges. Basically, they are made of substances like calcium carbonate, silicon dioxide, or protein and are embedded within the mesohyl layer of the sponge.

Answer:

The answer is 4

Explanation:

The answer is 4 because we are talking about pairs of homologous chromosomes and there  two copies  are held together and they are located in the centromere.

Synapsis is two homologous chromosomes pairing. During the event of meiosis homologous chromosomes are being pared but then also separated because of reducing the genetic content of the resulting haploid cells.
