Answer:
DNA replication is the process by that DNA make a copy to the cell division.
Explanation:
DNA replication is the double structure to the DNA molecule,it is biological process.DNA replication molecule the serve that template for the production to referred conservative replication.DNA replication occurs living the biological property of division and they performed complementary stand.DNA replication to that begin the specific location and origins in the genome, and growing from the origin.DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .DNA replication is the basis of single strand to 3 prime and 5 prime end, these refer to the carbon atom in the chain attaches.DNA replication allow the strand to the one another strand to used in partner strand.DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.While performing an experiment, it is important to:
a. change the control setup
b. test many different variables at the same time
c. reach a conclusion
d. record observations and measurements
Answer:
D
Explanation:
While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.
What is an experiment?The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.
Hence, while performing an experiment, it is important to record observations and measurements, as in Option d.

When you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very large molecules (thousands or even millions of nucleotides long), and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length). Which two classes of DNA do these different samples represent
Answer:
Leading strand and Okazaki fragments
Explanation:
The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.
The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.
This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.
The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

Proteins in the cell membrane have many functions. Which type of protein would be used for cell recognition and as a receptor? A. Pore proteins B. Endoplasmic proteins C. Glycoproteins D. Integral proteins
Answer:
C. glycoproteins
Explanation:
Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

What results if a broken chromosomal fragment becomes reattached as an extra segment to a sister or non-sister chromatid? A Duplication B Inversion C Polyploidy D Nondisjunction
Answer:
The correct answer is option A "Duplication".
Explanation:
Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

When a volcano erupts, tiny particles from which of Earth's spheres are released into the air?
atmosphere
biosphere
geosphere
hydrosphere
When a volcano erupts, tiny particles from the geosphere are released into the air. So, the correct option is C.
What is Volcano?A volcano is a geological formation on the surface of the Earth that develops as magma and volcanic ash build up. During an eruption, lava, ash, and gas can escape through a crater or vent that is generally shaped like a mountain.
Explosive or non-explosive eruptions can have a large negative impact on the environment, causing ash fall, landslides, and lava flows, among other things. Tiny geosphere-derived particles are discharged into the atmosphere during volcanic eruptions.
All areas of volcanism contain compound volcanoes, but these volcanic structures are most common at plate convergence zones, where one tectonic plate plunges beneath another towards the earth's mantle.
Therefore, the correct option is C.

Because he was well aware of the effect his theory of evolution would have on the public and on the Church of England, Darwin delayed publishing his work for several decades while he gathered additional evidence. After invoking selective breeding of domesticated species as evidence that groups of organisms are capable of change, he then proposed that natural populations can change as well. On which two lines of evidence did he base this proposal? a) Individuals within a population vary, yet island species around the world all appear to be related to each other.b) Organisms produce more offspring than can be supported by their environment, and adaptations to specific environments increase an organism's ability to survive and reproduce.c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.d) Some individuals leave more descendants than other individuals, but the individuals in a population are essentially identical to each other.e) Some individuals within a population have greater success in survival and reproduction than others, and favorable traits within a population will accumulate over generations.
Answer:
c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.
Explanation:
Darwin's theory was based on the evidence of natural selection and survival of the fittest.
Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).
Hence, the correct option is "c".
What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations
Answer:
Please find the detailed explanation below
Explanation:
A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.
Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)
Answer:
The answer is below
Explanation:
The weight of trees is calculated using the equation:
[tex]W=b_o+b_1(D^2H)[/tex]
W is the tree weight in tons, D is the diameter of the tree in inches, H is the height of the tree in feet and [tex]b_o \ and\ b_1[/tex] are constants.
The circumference is given by:
Circumference = 2πr
Where r is the radius and 2r is the diameter
Therefore:
14 = 2(22/7)× r
14 = (22/7)×2r
2r= 14 × 7 / 22
Diameter = 2r = 4.455 inches
[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381.643b_1\\Let\ us\ assume\ b_o = -35,b_1=1.9.\\Therefore\\W = -35+2381.643(1.9)\\W=4490 \ tons[/tex]

What are emergent properties?
Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.
Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.
What does the characters indicate at ?These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.
Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.
The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.
Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.
Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.
The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.
