Answer:
Just as helicase is responsible for unwinding the DNA strand, DNA polymerase is responsible for replicating the strand once it unwinds and separates. DNA is made up of a sugar-phosphate ladder and a nucleotide base.
Explanation:
Light speed, or 300,000 kilometers a second, might seem like a speed
limit, but this is just an example of 3 + 1 thinking – where we still
haven’t got our heads around the concept of four dimensional space-time
and hence we think in terms of space having three dimensions and think
of time as something different.
For example, while it seems to us
that it takes a light beam 4.3 years to go from Earth to the Alpha
Centauri system, if you were to hop on a spacecraft going at 99.999 per
cent of the speed of light you would get there in a matter of days,
hours or even minutes – depending on just how many .99s you add on to
that proportion of light speed.
This is because, as you keep
pumping the accelerator of your imaginary star drive system, time
dilation will become increasingly more pronounced and you will keep
getting to your destination that much quicker. With enough .999s you
could cross the universe within your lifetime – even though someone you
left behind would still only see you moving away at a tiny bit less than
300,000 kilometres a second. So, what might seem like a speed limit at
first glance isn’t really a limit at all.
To try and comprehend
the four dimensional perspective on this, consider that it’s impossible
to move across any distance without also moving through time. For
example, walking a kilometer may be a duration of thirty minutes – but
if you run, it might only take fifteen minutes.

The most likely change in air quality is a decrease in carbon dioxide (CO2) present in the box.
Photosynthesis is the process by which green plants produce their own food in the presence of light and carbon dioxide. The most important indicator of air quality is carbon dioxide. This gas is removed during photosynthesis.
This implies that after two days, analysis of the air samples from the pot will definitely indicate a large decrease in the amount of carbon dioxide present in the box.
Missing parts;
An airtight, temperature-controlled glass box containing actively growing tomato plants was placed under a lightsource. Plastic wrapping that only transmits green light was placed over the box, and two days later air samples frominside the box were collected and analyzed. The most likely change in air quality isa. an increase in nitrogen (N2)b. an increase in carbon dioxide (CO2)c. an increase in oxygen (O2)d. a decrease in carbon dioxide (CO2)

Answer:
Littoral Communities
Littoral areas of ponds and lakes are typically better oxygenated, structurally more complex, and afford more abundant and diverse food resources than do profundal sediments. All these factors lead to a high diversity of insects and very complex trophic interactions (see Section IV.

Answer: A chemical reaction is the change of a substance into a new one that has a different chemical identity. In summary, a chemical reaction is a process that converts one or more substances to another substance. Chemical reactions start with reactants and convert them into products. Most chemical reactions inside living things are regulated by enzymes, which speed up chemical reactions.A chemical reaction is a process that changes or transforms one type of chemical into another. ... Life is the result of countless reactions happening all at the same time, most often between carbon, hydrogen, nitrogen, and oxygen atoms. Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
