<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.
The amplitude of the waves decreases
The lower the sound volume is the lower the wave amplitude is.
The basic reason why unripe fruits have defensive chemicals is that they need to protect the seeds that are not ready to germinate. On the other hand, the seeds of the ripe fruits are ready to germinate and so they need to get spread with the help of animals and birds and so there are no defensive chemicals. These seeds spread to different places and the soils help them to germinate under suitable conditions.
Answer:
the surrounding area causes them to function differently than rather it be in a dry spot

The seizure disorder with a patient have a medication therapy fail and the patient had a resection of epileptogenetic tissue are called <u>focal seizures</u>.
Focal seizures start in one region of the brain but could extend to other regions as they become generalized. The most prevalent kind of treatment instead for seizures would seem to be medication. Depending on the nature of the seizures, the doctor might also advise nutrition therapy, nerve stimulation may be surgery.
Caffeine and alcohol should both be consumed in moderation. The best method to prevent seizures will be to avoid using tobacco as well as other other recreational drugs, receive sufficient sleep, manage your stress, and lead a healthy lifestyle.
