Have a nice day
Answer:
I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
Your answer is D, OH-! correct me if I’m wrong.
Answer:
The three types of organisms in an ecosystem are producers, consumers, and decomposers.
Producers get their energy by using sunlight to make their own food from water and carbon dioxide through photosynthesis.
Consumers get their energy by eating plants and animals for food as they cannot make their own food.
Decomposers get their energy by eating/scavenging and breaking down dead and decaying plant and animal bodies.
Hope that helps.
Answer:
4L
Explanation:
To obtain the volume of O2 at stp, first, we need to determine the number of mole of O2.
From the question given above,
Mass of O2 = 5.72g
Molar Mass of O2 = 32g/mol
Number of mole =Mass/Molar Mass
Number of mole of O2 = 5.72/32
Number of mole of O2 = 0.179 mole
Now, we can calculate the volume of O2 at stp as follow:
1 mole of a gas occupy 22.4L at stp.
Therefore, 0.179 mole of O2 will occupy = 0.179 x 22.4 = 4L
Therefore, the volume occupied by the sample of O2 is 4L
