In a neuroscience experiment, the one of these would best indicate LTP is Stronger and more frequent action potentials in the postsynaptic neuron.

<h3>What is long-term empowerment?</h3>

Long-term potentiation (LTP) is the increase in postsynaptic responses over hours, days, or weeks after brief repetitive stimulation of presynaptic afferents.

However, for study purposes, LTP is commonly divided into three sequentially occurring phases: short-term potentiation, early LTP, and late LTP.

Which data would not affect maximum likelihood estimates of phylogenies when comparing different tree hypotheses?.
Solnce55 [7]

The tree topology

The lengths of the branches

The branching order of the tree

Nucleotide substitution rate

These would not affect maximum likelihood estimates of phylogenies when comparing different tree hypotheses.

<h3>What is tree topology?</h3>
  • A unique kind of structure called a tree topology has numerous connected parts arranged like the branches of a tree.

<h3>The lengths of the branches:</h3>
  • Branch lengths are a sign of genetic divergence; the longer the branch, the more genetic divergence has taken place.
  • Usually, we calculate the average number of nucleotide or protein substitutions per site to assess the degree of genetic alteration.

<h3>The branching order of the tree:</h3>
  • The topology of a tree refers to its branching structure.
  • Species (or higher taxa), populations, genes, and proteins are examples of taxonomic units that the nodes represent.
  • A branch is referred to as an edge, and it represents an estimate of the length of time between the evolutionary relationships between taxonomic units.

<h3>What is nucleotide substitution rate?</h3>
  • The instantaneous rate of change from each of the four nucleotides to each of the other four nucleotides is summarized in the nucleotide substitution rate matrix.

Life on earth began as the product of chemical reactions which occurred
Kazeer [188]

Answer: Over 4 billion years ago

Explanation: The chemical reactions between carbon and water is said to bring about life according to scientists. These reactions builds largely upon four families of chemicals (lipids, carbohydrates, amino acids, and nucleic acids).

However, the actual time of life on Earth has varying speculations from different scientists in fields of study (such as molecular biology, chemistry, oceanography, etc).

Furthermore, microfossils within hydrothermal-vent precipitates dated from 3.77 to 4.28 billion years is presumed to inhabit the oldest record of life on Earth. Hence, which is presumed to have occurred after ocean formation 4.4billion years ago.

Thus, the actual date of the chemical reactions that brought about life is not rigid, but presumed to have occurred over 4billion years ago (according to research).
