Explanation:
New strands of DNA are lengthened by adding new nucleotides at the replication fork.
These methods primarily involve DNA synthesis techniques, such as polymerase chain reaction (PCR) and DNA sequencing methods. However, it's important to note that scientific advancements may have occurred since my knowledge cutoff, and there could be new techniques or technologies available.
PCR is a widely used technique that allows for the amplification of specific DNA sequences. It involves a series of heating and cooling cycles, which enable the DNA to denature (separate into single strands) and then be replicated using a DNA polymerase enzyme. By repeating this process, multiple copies of the DNA sequence of interest can be generated.
DNA synthesis involves the chemical synthesis of custom DNA sequences in the laboratory. This process typically employs a method called phosphoramidite chemistry. It starts with a DNA template strand and adds nucleotides one by one, using chemical reactions to build the new DNA strand. This method allows for the controlled synthesis of long DNA strands with specific sequences.
Modern DNA sequencing technologies, such as next-generation sequencing (NGS), can indirectly contribute to DNA lengthening. During the sequencing process, DNA strands are often amplified and replicated to generate sufficient material for analysis. This amplification step can result in the lengthening of DNA strands.

A nuclear chain reaction happens when a single nuclear event averages out one or more further nuclear reactions, opening the door for a potentially endless chain of similar processes. Therefore, option (A) is correct.
What is a nuclear chain reaction ?A nuclear chain reaction happens when the output of one nuclear reaction triggers the occurrence of further nuclear reactions. These cascade reactions are nearly invariably a succession of neutron-excessive fission events. The moniker "chain reaction" comes from the fact that these extra neutrons have the potential to trigger more fission events. The functioning of nuclear power plants depends on nuclear chain reactions.
About a million times more energy is released during nuclear reactions than during chemical ones. Every fission event must result in precisely one additional fission event in order for a nuclear chain reaction to continue.
Therefore, option (A) correctly describes the nuclear reaction.

why does cell division occur in sexually reproducing organisms?
Answer:
to produce a complex multicellular individual
Explanation:
hope this helps
Cell division occurs in sexually reproducing organisms to maintain the organisms growth and development. Cells have a particular life cycle after which they die. These cells need to be replaced constantly.
What is Cell division?Cell division is the fundamental process to all living organisms and required for the growth and development of organisms. It is an essential means of reproduction for all the living things, cell division allows organisms to maintain their number and to transfer their genetic material to their offspring.
The role of this process in sexual reproduction is to produce sex cells (gametes) and to repair the genetic defects in germ line cells (sex cells). Both sexual and asexual organisms go through the process of mitosis. However, sexual reproduction also includes meiosis which maintains the number of chromosomes in off-springs.

A.acids
B.enzymes
C.products
D.substrates
Answer:
90% Products, 10% Acids
Explanation:
enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.
But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.
Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.

How can a star be extremely hot like Alpha Canis Majoris (4 times hotter than our sun) but give off so little light (only 2% of our sun’s light)?
It's on Earth Science.
Answer:
this is due to the fact that stars are suns of other galaxy as we know that we have about a million galaxies in space. the earth is located in the milky way galaxy so these stars are about a 150 billion kilometres from earth
Solar radiation is a broad word for the electromagnetic radiation that the sun emits. It is also sometimes referred to as the solar resource or just sunshine. A multitude of devices can be used to collect solar radiation and transform it into useful forms of energy, such as heat and electricity.
How much of the Sun do we actually see?Sunlight at Earth's surface is roughly 42 to 43 percent visible (400 to 700 nm), 52 to 55 percent infrared (above 700 nm), and 3 to 5 percent ultraviolet in terms of energy (below 400 nm).The Sun always emits the same amount of energy. Insolation refers to the incoming solar radiation. Seventy percent of solar energy makes it to the planet.99.8% of the mass in our solar system is found in the Sun. Everything, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion light-years away, is kept in place by its gravitational attraction.What would occur if our distance from the Sun increased by 10%?More radiation, ultraviolet rays, heat, and other rays would be directed at our atmosphere. It would be impossible to live. According to my projection, the global average temperature would increase from 16 C to 65 C. (149 Fahrenheit). This would be high enough to prevent most life from existing, yet low enough to prevent water from boiling.The solar system itself, the Sun Between 99.8 and 99.9 percent of the mass of the solar system is found in the Sun. The remaining matter is distributed among the planets and their satellites, asteroids, comets, and the gas and dust that surrounds our star.To learn more about Solar radiation, Refer:

approximately how many nucleosomes are required to organize this region of dna into the 10nm fiber structure?
Answer:
Answer is 512 nucleosomes.
Explanation:
DNA is the genetic material that is compressed and stored in the nucleus of the cell. Approximately 512 nucleosomes would be required to organize 92,672 base pairs long region.
What are nucleosomes?Nucleosomes are the packaging units of the genetic material that comprises the DNA segments wrapped along with the histone proteins in a compacted manner. This allows the genetic material to be condensed into smaller volumes.
Given,
Genome size = 92,672 base pairs
Linker DNA = 35 bp
The total number of base pairs = number of base pairs in nucleosome core + linker DNA
= 146 + 35
= 181
The number of nucleosomes can be calculated as:
Nucleosomes = Genome size ÷ total number of base pair
= 92,672 ÷ 181
= 512
Therefore, there are 512 nucleosomes are present in the Drosophila.
