Explain how the distribution of the similar rock types can be used as evidence for continental drift

Biology
1 answer:
anastassius [24]3 years ago
7 0

Explanation:

Similar rock types can be used as an evidence for continental drift because rocks forms under different geologic conditions.

Most natural depression on the earth surface are filled with thick sedimentary sequences that have been subjected to lithification.

In some terrain, magmatic activities are rife with prevailing tectonic settings controlling how they cool and solidify.

Also, some terrains have experience prolong metamorphic change and this dives spurious metamorphic transformation of minerals.

  • A terrain will have a rock type that typifies it.
  • If the two terrains become separated, it is possible to correlates the rock sequences in them.
  • For sedimentary rocks, a geologic column and stratigraphy can be useful on correlating them.
  • In metamorphic rocks. different facies have typical index minerals in them that can be used to match them.
  • Dating some minerals in igneous rocks and even establishing sequences have proven useful in explaining continental drift between terrains

What is the the process of making a copy of a gene.
Anon25 [30]

Answer:

The process of making a copy of gene is called DNA replication.

Explanation:

This is a four step process. In first step, the DNA molecule which is double helical structure is unzip. This is carried out by enzyme called helicase which is also called biological scissors. Then after that DNA form Y like structure having complementary base pairs. Two strands are formed ; leading strand and lagging strands. They complementary base pairs allow the formation of new strands with help of primer. So new strand is then a copy of gene or called replicated strand.

The terms 'respatialization' and 'deterritorialization' refer to the same thing.​
Alinara [238K]

The answer is False.

Spatialization (spatialisation) can refer to the spatial forms that social activities and material things, phenomena or processes take on. This term related to geography, sociology, urban planning and cultural studies. Generally the term refers to an overall sense of social space typical of a time, place or culture.

7. Adenine (A), Guanine, Cytosine and Thymine are the four nitrogenous bases in DNA.

8. In DNA Cytosine always forms hydrogen bonds with guanine.

9. The sequence of nucleotides carries the genetic information of an organism.

10. The process of replication produces a new copy of an organism's genetic information which is passed on to a new cell.

11. The double-coiled shape of DNA is called a double helix

Explanation:

There are four nitrogenous bases in the DNA of an organism. Two of the bases are pyrimidines eg: Thymine and cytosine while 2 of the bases are purine  bases namely adenine and guanine. The purine of one strand forms a hydrogen bond with pyrimidine of the parallel strand of DNA.

The bases are present in nucleoplasm as dNMPs and in DNA they are present as dNTPs (deoxyribonucleotide triphosphate). During replication, these dNMPS keeps on bonding with other dNMPs in the presence of ATP and as DNA Polymerase, ligase topoisomerase etc. These nucleotides form the DNA strands and they are responsible for coding proteins. The sequence of DNA is also termed as gene.

The double helix structure of DNA was given by Watson and Crick. Each strand has an alternative backbone of sugar and phosphate group. The four bases bonds with glycosidic and phosphodiester bonds with sugar and phosphoric acid.
