Using the graph in Source 3.2, calculate the increase in CO2 concentration, in parts per million, between 1975 and 2000:
A
40 ppm
B
60 ppm
С
330 ppm
D
365 ppm
so

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

b.have there own function.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
