<h3><u>Answer;</u></h3>
C.) The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
<h3><u>Explanation</u>;</h3>
- Molecular clocks are used to date origin of species. They are based on the observation that random mutations accumulate in genes at a fairly constant rate
.
- Once a mutation rate is determined it can be used to establish dates of divergence of species.
- Molecular clocks can be used in putting a series of evolutionary events into chronological order, by comparing sequences from different species to determine when they last shared a common ancestor, in effect drawing the family tree.
6 carbon
12 hydrogen
I’m pretty sure
Answer:
Both are true
Explanation:
parasitic plants have chlorophyll. They can photosynthesize their food.e.g picture plant.
It is now a new chemical reaction and has different properties now.
The correct order is:
1. Neutral
2. Harmful
3. Beneficial
Neutral mutations have no effect on organism and the majority of mutations are neutral
Harmful mutations (or deleterious) may cause genetic disorders and those mutation decreases the fitness of the organism.
Beneficial mutations (or advantageous) increases the fitness of the organism and may become more common through natural selection.
