Glucose is broken down to carbon dioxide and water in organisms which breathe air in a process called cellular respiration.
Answer:
I believe the correct answer is option <u>C. Reactants: carbon dioxide and water products: oxygen and glucose.</u>
Explanation:
I'm pretty positive that the two main reactants are carbon dioxide and water, while the products are oxygen and glucose. Carbon dioxide and water + sunlight are the reactants which are present at the start of the reaction <u>6co2+6h2o c6h12o6+6o2.</u>

Answer:
Your heart changes its rate depending on the activity, so that it can carry blood to your muscles, and therefore it needs to beat stronger if you are performing some exercise, or not so strong if you are sleeping, for example.
Explanation:
Your heart is continuously beating to keep blood circulating throughout your body.
So, here it is why your heart changes its rate: Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.
And how: depending on your activity level, your heart has to pump enough blood to your muscles. Blood carries needed oxygen and other nutrients. Muscles need more blood sugar than any other tissue especially when working hard. To supply your muscles with oxygen your heart needs to beat faster, and this builds up your heart muscles.
Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
True
Renewable energy processes present us with alternative sources of energy.The alternative energy sources applied to the energy sources other than remains in the form of fossil fuels. These energy sources are existing in the structure of solar power, tidal energy, geothermal power, electricity obtained from wind energy, and biomass.
