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

Answer: 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

What happens to excess carbohydrates in animals
Mademuasel [1]
The excess carbohydrates in animals<span> turn into glucose, which your body will eventually burn immediately or it will convert it to glycogen which would be stored in the muscles and in the liver for the between meals. 

I hope this is what you're looking for and have a great day!! :)</span>

Your group is conducting an experiment to test the effect of Earth's gravity on objects of different masses. Your group drops fo
natta225 [31]

Answer:

A) The paper is affected by air resistance due to its flat shape, so wadding the paper into a tight ball would cause it to hit the ground at the same time as the other objects.

Explanation:

<u>I am so sorry if this is incorrect! But after some research, this is what I found. </u>

Aristotle said that there are 4 elements: Earth, Wind, Water, Fire. Objects made of earth (like a rock) will want to go the center of the universe (center of the Earth). Things made of fire want to go to the place where fire is. I guess this would be the Sun - or somewhere up. Aristotle also said that a heavier object will fall at a faster speed.

Here is the first classic example. This is a bowling ball and a basketball dropped from the same height. Normally, people would assume thatn the bowling ball would drop quicker. They are correct. Please note that heavier objects do not always fall faster though.

I hope I answered your question! please give brainliest!
