Tanzania [10]

Answer:

Photosynthesis produces: <em>glucose </em><em>and </em> O_{2}

                 ...from  CO_{2}, energy (light) and H_{2} O

Respiration produces: energy (ATP),CO_{2}, H_{2} O  

                ....from <em>glucose </em><em>and  </em>O_{2}<em />

<em />

Explanation:

These end products, namely O_{2} and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6CO_{2} + 6H_{2} O + (energy) →C_{6} H_{12} O_{6} + 6O_{2}

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3>C_{6} H_{12} O_{6} + 6 O_{2}  _{\to \ 6CO_{2} + H_{2} O + energy (ATP)</h3>

The waste products, CO_{2} and H_{2} O,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants O_{2}  and C_{6} H_{12} O_{6} in respiration.

I need help, I don't understand this, so please try to explain?
Vinvika [58]

Answer:

Yeah, so basically the image is showing restriction enzymes. The job of restriction enzymes is mainly involved in research when scientists use them for cloning human genes. But that's besides the point...

Main thing you have to understand is that restriction enzymes cut at very specific places along DNA sequences. If you look at the restriction enzyme Rsa 1, you can notice that it cuts only between a thymine nucleotide base and an adenine nucleotide base. Next, if ya look at Sty 1 (be careful b/c W can represent adenine or thymine), it cuts only between two directly adjacent cytosine nucleotide bases!

SO.... if we go to Rsa 1, we can find the answers by dividing up the sequences between the pattern we saw in the gray box. It only cuts between adenine and thymine bases. Based on that, we can find the number of fragments created, and the segment lengths (basically just like how many nucleotide bases are in each strand). Hope ya found this helpful!
