of course answer is thymine
The pigments have a similar
structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while
xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls,
hence move farthest in chromatography
paper using a nonpolar mobile phase. Chlorophyll
pigment, on the other hand, has chlorin rings (which are larger) as functional
units hence move slowly in chromatography.
Photosynthetic rates
can be measured by either the amount of
oxygen they consume per particular time period
or the amount of carbon dioxide produced per particular time period. This
is conducted while immersed in water so
as to measure bubble rate formation in case of oxygen production or the change
in water pH in the case of carbon dioxide consumption.
When autumn approaches, the amount
sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing
chlorophyll a and b pigments (most important in photosynthesis)
during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from
green to yellow-red.
It is believed that this
is the result of an ancient endosymbiotic
relationship between a protist and a
eukaryotic cell. The protist generates energy
that the eukaryotic can utilize in its growth and reproduction while
the protist is sheltered. This relationship became obligatory symbiosis over
time.
Answer:
The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.

Answer:
In my opinion, a reduction in our use of energy would not be a historical step backwards.
Explanation:
We already know that humanity's consumption of fossil fuels is wreaking havoc on the ecosystem. Fossil fuels pollute the environment where they are generated and utilized, and their continued usage harms the climate of the entire world. Nonetheless, altering our behaviors in a significant sense has proven to be quite difficult. As a result, it is not impossible to reduce our energy use significantly, but we may take little efforts to change the way we create energy, such as using fossil fuels. Because fossil fuels are so detrimental to our environment, we should try to reduce its use, but not at the risk of improving our surroundings. There are several methods to change the way we utilize energy now into something more sustainable.
