Lichens and moss for sure

Answer:

lichens and moss

Explanation:

Lichens are formed when there is a relationship between fungi and algae, that is, a symbiotic one, as it is a union that is advantageous for both. These organisms would probably appear if a rocky island appeared out of the water due to volcanic activity, because of all the humidity that would favor fungi and because of the presence of algae in the aquatic environment. Lichens reproduce asexually on rocks, soils, barks and tree trunks, through propagules called soredium that contain algae cells and fungi hyphae.

Mosses, in turn, live in humid and shaded environments. They can grow under different substrates such as soil, rocks, tree trunks and even walls. Some species of mosses form true green carpets, covering large areas. It would be very common for mosses to appear if a rocky island appeared out of the water due to volcanic activity, due to all the humidity in the place.

What is the point of DNA replication​
Degger [83]

Answer:

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell

Explanation:

DNA replication is the biological process in which two identical copies of DNA are produced from one original DNA molecule.

The steps involved in the process of DNA replication are as follows:

The first step in DNA replication is to ‘unzip’ the double-helix structure of the DNA molecule.

This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).

The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.

One of the strands is oriented in the 3’ to 5’ direction (towards the replication fork), this is the leading strand. The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the lagging strand. As a result of their different orientations, the two strands are replicated differently.

A short piece of RNA called a primer (produced by an enzyme called primase) comes along and binds to the end of the leading strand. The primer acts as the starting point for DNA synthesis. DNA polymerase binds to the leading strand and then ‘walks’ along it, adding new complementary nucleotide bases (A, C, G and T) to the strand of DNA in the 5’ to 3’ direction. This replication is continuous. Numerous RNA primers are made by the primase enzyme and bind at various points along the lagging strand.

Chunks of DNA, called Okazaki fragments, are then added to the lagging strand also in the 5’ to 3’ direction. This type of replication is called discontinuous as the Okazaki fragments are joined up later.

Once all of the bases are matched  (A with T, C with G) an enzyme called exonuclease strips away the primer(s).

The new strand is proofread to make sure there are no mistakes in the new DNA sequence.

Finally, an enzyme called DNA ligase seals up the sequence of DNA into two continuous double strands.

The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.

Following replication, the new DNA automatically winds up into a double helix

(b) DNA replication occurs in S phase of cell cycle in eukaryotes. If cell division is not followed after DNA replication then the replicated chromosomes (DNA) would not be distributed to daughter nuclei. A repeated replication of DNA without any cell division results in the accumulation of DNA inside the cell nucleus, leading to polyploidy.

The principle that the geologic processes that we see today have occurred throughout Earth’s history is called____.
nignag [31]

Answer:

A. Uniformitarianism

Explanation:

The principle of Uniformitarianism was proposed by a Scottish Geologist, James Hutton.

The principle is simply stated as "the present is the key to the past".

The processes that have occurred in geologic past is still in play today. By looking at rock sequences in our present day, we can actually have a firm grasp of the processes they have undergone in the past.

What’s the difference between Food, chyme and bolus?<br> No goggle answer!
djverab [1.8K]

Answer:

Bolus is the food that is mashed up in your mouth. After it is digested in the stomach, the food is called chyme. Bolus is more alkaline than chyme because it is exposed to alkaline saliva.
