What feature of double-stranded dna makes it necessary to have a leading strand and a lagging strand during replication?.
Answer:
there must be a pre-existing chain of nucleotides
Explanation:
So RNA primers are used for initiation of new DNA chains.
RNA primer is short piece of RNA, synthesised at the end of the new strand with the help of DNA specific RNA polymerase enzyme called primase and primers provide free -OH for DNA polymerase to start polymersing. leading template strand requires primer only ones. But lagging template strand requires many primers. Once primer is ready DNA Pol(III) will come & start adding deoxyribonucleotide to the -OH of primer by complementary basepairing. Two nucleotides link each other by phosphodiester bond. The daughter DNA for template is synthesised continuously, Therefore called leading strand. DNA polymeraseIII has Exonuclease activityIt can add nucleotides in the direction. Replication is discontinuous on the other template with polarity because only a short segment of DNA strand can be built in direction due to exposure of a small stretch of template at one time.

Sharks and whales are a classic example of two different animals revealing
similar traits in the same environment. One of the similarities of these two
marine animals is their habitat. They both live in the vast range of depth in
their environment. They also have the same fin structure. They only have a
single tail for propulsion and because they are both large aquatic animals,
they both consume large volume of food, however, sharks hunt for their
food. Whales do not have this hunting tendency. Another difference of
sharks to whales is their class. Whales are mammals while sharks are fish
but they both live in the ocean. Also, whales have bones while sharks only
have cartilages.
Answer: The similarities between shark and whales are indicative of convergent evolution.
Explanation:
Convergent evolution can be defined as the process in which the organisms are not closely related but they evolve similar traits as a result of living in a similar kind of environment or adapting traits which enable them to perform the same ecological niches.
The similarities between shark and whale is indicative of convergent evolution as the animals are not related to each other phylogenetically but they live in the same environment this they evolve same kind of traits.
The similarities between sharks and whales represent an example of convergent evolution.
Convergent evolution refers to the evolution of similar phenotypic traits in unrelated and/or distantly related species.Convergent evolution creates analogies, i.e., different structures that may have the same function but were not present in the last common ancestor of both species. On the other hand, divergent evolution refers to the development of dissimilar phenotypic traits in closely related species as a result of evolution by natural selection, thereby leading to speciation.In convergent evolution, similar phenotypic features (traits) have evolved independently and repeatedly in each lineage in order to adapt to particular environmental conditions.In conclusion, sharks and whales are an example of convergent evolution because they are distantly related species that exhibit similar phenotypic features in the same environment.

To construct linkage maps, scientists estimate the distance between genes on the same chromosome based on the ______, as indicated by the percentage of recombinant offspring.
To construct linkage maps, scientists estimate the distance between genes on the same chromosome based on the crossover frequency. It is also called recombination.
What is a crossover?Crossover or recombination is the interchange of genetic material between non-sister chromatids during meiosis.
In genetics, this rate of recombination is useful to develop linkage maps (i.e., genetic maps).
These genetic maps are not equal to distance maps, which are constructed based on nucleotide distances.

Mindful eating includes which behavior?
feeling the textures of your food
eating while watching television
O photographing every meal that you eat
O recording every calorie that you consume
Answer:
A, "feeling the textures of your food."
Explanation:
While every option does appear mindful, only A is the correct answer. The true definition of mindful eating is that you are paying undivided attention to your food and how it makes you feel. This includes the aroma, textures, and your sensual awareness. This does not involve computing calories or partaking in obsessive behaviors. Watching television while you eat would be distracting you from the experience.
name and define the states of energy
Answer:
There are two states of energy: potential energy and kinetic energy.
Potential energy is stored energy – energy that is ready to go. Potential energy can be used in combination with other terms like “gravitational potential energy,” which is the energy an object has due to height in comparison to a lower elevation.
Kinetic energy, simply put, is energy something has because of its motion.

Describe and explain the three basic cyclic reasons why the temperature of the Earth has fluctuated over time (Milankovitch Cycles). Please make sure to use complete sentences and proper grammar.
PLEASE HELPPPPP
The three basic cyclic reasons why the temperature of the Earth has fluctuated over time are Eccentricity, Obliquity and Precession.
The Milankovitch CyclesThe Milankovitch Cycles are defined as the cyclical movement related to the Earth's orbit around the sun. These cycles cause variations in the amount of solar energy reaching the Earth.
Milankovitch Cycle was developed by the Serbian mathematician called Mulutin Milankovitch.
The climatic effects of the Milankovitch Cycles include:
Eccentricity: This is defined as the shape of Earth's orbit. This cycle is the reason why the seasons are slightly different in length.Obliquity: This is defined as the angle that Earth's axis is tilted with respect to Earth's orbital plane. The greater Earth’s axial tilt angle, the more extreme our seasons are.Precession: This is defined as the direction that Earth's spin axis is pointed. Axial precession makes seasonal contrasts more extreme in one hemisphere and less extreme in the other.Learn more about earth's temperature here:

Raj takes a meteorology class and learns about the effects of air density on the weather. What affects the density of air? Explain.
Answer:
Temperature, pressure, and moisture/humidity are all factors to consider.
Warm air has a lower density and rises/becomes buoyant.
The air is less dense at higher elevations above sea level. To bring the same amount of oxygen into the lungs when running at high altitudes, you'll need to take more deep breaths.
Humidity is less dense at higher temperatures and pressures. The weight of water molecules is less than that of nitrogen and oxygen molecules. To get more moisture into the same volume of air, some of the heavier nitrogen and oxygen must be displaced.
Explanation:
Firstly, plant cells have a cell wall that surrounds the cell membrane, whereas animal cells do not. ... These additional organelles allow plants to form an upright structure without the need for a skeleton (cell wall and central vacuole), and also allow them to produce their own food through photosynthesis (chloroplasts).
Answer:
Explanation:
This question appears incomplete. However, one of the main differences (in organelles) between plants and animal cells is the absence of cell wall and chloroplast in animal cells while both organelles are present in plant cells. The cell wall is outside of the cell membrane. The cell wall provides rigidity and support to the plant cell while the chloroplast is the cellular "machinery" for photosynthesis. The chloroplast contains the green pigment called chlorophyll which provides green plants with there colour and assist the plants in absorbing/capturing of sunlight/energy for the purpose of photosynthesis (self production of food by green plants).
