Answer:
Scientist 1
Explanation:
<em>The conclusion of scientists 1 is valid.</em>
Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>
Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.
<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>
Explanation:
%DV label= 27%
1 cup of cooked collared greens= aprx 266.60 mg of Calcium
Assuming Clara is...
- a teen, her required adequate intake (RAI)= 1300 mg/ day
- an adult, her RAI= 1000 mg/day
For teenaged Clara
∵27 % DV= 270mg
% daily Calcium= 
= 20.8 ≈ 21%
=0.21
<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>
Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.

The right answer is facilitated diffusion.
Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.
Answer: It's known as the continental drift :)
Explanation: "Pangea's existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”" (copied from google)
