6 0

Answer:

15 protons

Explanation:

In a neutral atom (not an ion or isotope) the amount of protons will be the same as the atomic number and the number of electrons.

An ion will have different electron values.

An isotope will have a different number of neutrons and a different atomic mass.

Cladograms (a type of phylogenetic tree) constructed from evidence from molecular systematics are based on similarities in
defon

Answer:

The correct answer is "mutations to homologous genes".

Explanation:

The missing options of this question are:

A) morphology.

B) the pattern of embryological development.

C) biochemical pathways.

D) habitat and lifestyle choices.

E) mutations to homologous genes.

The correct answer is option E) "mutations to homologous genes".

Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.

Describe the four stages of the hypothesis for the origin of life on earth by chemical evolution
VashaNatasha [74]
It would be nice to see the 4 stages titled to have a clue to what they could be. You see, chemical evolution is a myth, like Darwin's "warm little ponds." There are no naturalistic processes that have any power to accomplish the complex, diverse, extensive and highly non-entropic assembly of biochemical elements, molecules and assemblies into even the simplest life.

There is no primordial soup, panspermia is a distraction, none of the intractable issues for the origin of life.

Logically, the first step is collection of all elements, second, first level assembly of amino acids lipid membranes, proteins, third, higher level combination of biochemical molecules and generation of nucleotide coded DNA containing the processing code for generation and production of RNA, enzymes ribozymes and all other cellular functions, then fourth, the execution of all metabolism, nutrient collection, waste elimination and reproduction consistent with a living organism. Admittedly speculative since chemical evolution is a myth.
