Answer:

The answer is A) a living thing dies and sediment is very slowly deposited on top of its body.

Explanation:

The formation of a fossil depends a lot on the chemical composition of the organism that has died. Generally, the hard materials of an organism such as bones tend to have a greater amount of minerals within their composition, which facilitates the formation of a fossil. In order for a fossil to form, it is necessary that all the soft tissues of the organism have disappeared and sedimentation of the organism occurs, which prevents decomposition. This fossilization process occurs in thousands of years.

It would be A, because a fossil forms after an animal dies, and hundreds to thousands of years of soil or sediment coversit's body, preserving it. :)

A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc

Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

ATCGCAA

The Mutated strand is: TGGCGTT

ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em> CTTAGTG</em>

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.
