Understand how fossils, the Law of Superposition and geologic timescale support the theory of evolution

1 answer:

The fossils which are plants and animal remnants change over time. The Law of Superposition is a law that governs the geochronology, which states that in any undisturbed sequence of rocks deposited in layers, the youngest layer can be found on the top and the oldest can be found at the bottom, with each layer being younger than the one under it and older than the one above it.
These elements works in a synergy to explain and to help persons of interest understand the idea of evolution which stresses out that the modern day species came from a distinctively different species.

The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.

Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.

These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)

A complete plant gene containing four introns and five exons is carried on a 6.0-kb DNA fragment. DNA sequencing analysis finds

damaskus [11]

Answer and Explanation:

the total length of the gene is 6,000 base pairs (or) 6.0 kb and it has five exons, four introns and a 1,000 base pair length flanking region for the transcribed region.

Hence, each exon has (1500/5) = 300 by

each intron has (3500/4) = 875 by and

flanking segment (5' and 3') length for the transcribed region would be (1000/2) = 500 bp.

The gene segment is as shown in the 1st diagram attached below

In eukaryotes, transcription takes place in the nucleus which results in the synthesis of hnRNA (heteronuclear ribonucleic acid). This hnRNA (pre-RNA) has both introns and exons, however when it is synthesized or while it is being synthesized the Spliceosomal complex removes introns from hnRNA and becomes converted into mRNA (messenger RNA) in the nucleus itself.

(second diagram explains further)

Now the synthesized mRNA reaches the cytoplasm. So, if mRNA collected from the nucleus and cytoplasm will have the same length of about 2,500 base pairs only. Therefore, after the commencement of northern blot analysis both mRNA will yield the same kind of result and have unique length.
