B , because there is more than one path of energy coming from the plants but if it’s not B then it’s A because arrows that are all over the place is what makes it a web
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat-trapping causes changes in the radiative balance of the Earth-the balance between energy received from the sun and emitted from Earth-that alter climate and weather patterns at a global and regional scale.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years. Natural Factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

Answer:
8
Explanation:
The fly has only 3 pairs of somatic chromosomes, that means that only can combine 3 chromosomes. To calculate the combinations the exponential 2n it is used. In this case is 2 to the third power that is equal = 2 x 2 x 2 = 8
This fly also has a fourth pair, but this one is the sexual one, so the main function of this gene is to give the sex to the offspring.

Percent composition by element
Element Symbol # of Atoms
Barium Ba 1
Hydrogen H 2
Oxygen O 2
Chem was fun last year XD
Anyway..
To find how many neutrons are in element x:
We take the mass number and subtract it with the atomic number
So, 75-22=53 neutrons...BOOM! :D
