It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
<h3>How are isotopes used in radioactive dating?</h3>
These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.
Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to be <u>convergent</u>.
A neuron in such a network can take information from numerous other neurons through convergence. Inhibitory interneurons are activated by presynaptic cells, but instead they reduce nearby cells inside the network.
Synaptic divergence refers to the dispersion of synapses from such a single neuron onto several postsynaptic partners as well as partner kinds, while synaptic convergence refers to being affected by having neuronal cell kinds delivering input around on a shared postsynaptic partner.
Multiple presynaptic cells send convergent information to a single postsynaptic neuron.

Answer: After seven months.
Explanation:
The blood carries various substances that must be transported from one part of the body to another. Red blood cells are an important component of the blood because their function is to carry oxygen to the body tissues and exchange it for carbon dioxide, which is carried and removed by the lungs.
Erythropoiesis is the process of red blood cell (erythrocyte) production. It is stimulated by a decrease in O2 in the circulation, detected by the kidneys, which then secretes the hormone erythropoietin. This hormone stimulates the proliferation and differentiation of red blood cell precursors, which triggers an increase in erythropoiesis in hematopoietic tissues and ultimately in the production of red blood cells. <u>In adults, red blood cells are formed in the red bone marrow.</u>
In early developing fetuses, erythropoiesis occurs in the mesodermal cells of the yolk sac. In the third or fourth month, erythropoiesis moves to the liver. After seven months, erythropoiesis occurs in the bone marrow.
