Scientists use radioactive decay to date fossils and artifacts through a process called carbon dating it measures the amount of carbon still left in a dead object. The less carbon that exists, the longer that animal or plant as been dead.
The part anti means opposed. Biotic is basically all the naturally occurring organisms. So an antibiotic would oppose an organism like a virus.
Answer:
The humoral immune response involves mainly B cells and takes place in blood and lymph.
Explanation:
Answer – B (Electrons)
When atoms combine, their nucleons fuse to produce a new nucleus and interactions occur between their electrons, particularly the outer valence electrons. The interaction between the outer valence electrons of the combining atoms forms bonds between them.
<h2>Answer with Explanation </h2>
The electron that carries is use in redox reaction in the cellular respiration is a complex process. The electron carriers are needed to transport the electrons. The electron transfer that which is used during redox reaction in the cellular respiration is NAD+(NADH2). NADH is oxidized back to NAD+, and FADH2 is oxidized back to FAD. This stored energy can then be used to generate ATP. The ATP basic energy currency of a cell.
