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.

Explanation:
The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.
Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.
- Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
- Tool man also grazed the surface of the earth just a few thousands to a million years.
- We are able to find their fossils in rocks because they have lived in some certain geologic periods.
- Here we are using the fossils to date the rock and this is called relative dating

Answer:
The answer would be B; recombination DNA technology
Answer:
Evolution is the gradual change in the inherited traits of a population over several generations. natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass their genes
Answer:
A) histone coding genes
Explanation:
Histones are the proteins involved in the packing of DNA in eukaryotes. They are positively charged proteins and are not found in bacteria. To analyze the evolutionary relationship in a gene between eukaryotes and bacteria, one must choose the gene present in both of them. The tRNA, rRNA and hexokinase encoding genes are common to both bacteria and eukaryotes. Therefore, one of these genes may be chosen for the study. However, histone encoding genes are not present in the genomes of bacteria. Therefore, the study of the histone encoding gene would not be useful for the mentioned purpose.
