Review the section "Investigating Life: Solar-Powered Salamanders." The researchers added CO2 tagged with a radioactive isotope of carbon to a solution surrounding salamander eggs and incubated some eggs in the light and some in the dark. After two hours, the researchers measured the amount of radioactivity in the eggs and found that the eggs incubated in the light had more radioactive carbon than the eggs incubated in the dark. What process occurred in the eggs incubated in the light but not in the eggs incubated in the dark to account for the higher amount of radioactive carbon?

A) photorespiration
B) photosynthesis
C) diffusion of CO2
D) cellular respiration that produces CO2

A) photosynthesis

Explanation:

Photosynthesis is the process by which plants make their own food in the presence of sunlight  by utilising carbon dioxide (CO2) and water (H2O) and form oxygen (O2) and glucose(C6H12O6).

In the Solar-Powered Salamanders, salamander eggs undergoes the process of photosynthesis when incubated in light and dark conditions. The egg incubated in light condition utilises more carbon isotope  as catalysed by the light source, same as photosynthesis and shows more radioactive carbon. Due to the adsence of light, the other egg is unable to consume much carbon isotope.

Hence, the correct option is A) photosynthesis

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
