What are the processes that change one type of rock into another type in the rock cycle?

Biology

Answer:

  • Crystallization (cooling or solidification)
  • Erosion and sedimentation (lithification, burial and deposition)
  • Metamorphism (Melting due to heat and pressure)

Explanation:

In rock cycle, there are three important processes that changes one type of rocks into another type. Those processes are:

  • <u>Crystallization:</u>  It is a process that takes place under the earth surface where magma cools down and is hardened to form igneous rocks. This process is also called freezing of rocks.
  • <u>Erosion and sedimentation:</u> The rocks on the surface of earth are broken into smaller fragments called sediments that are formed by weathering of rocks. These sediments are then carried either by wind or water to different places and settles at some place to form another type of rock named sedimentary rocks.
  • <u>Metamorphism:</u> Metamorphism takes place under the earth surface where extreme heat changes the mineral texture of the rock but does not melt it. such rocks are named as metamorphic rocks.

The nucleoside analogue acyclovir, which is used to treat herpes simplex virus (HSV) infections, lacks a 3′ hydroxyl group (–OH)
Dima020 [189]

Answer:

There won't be any functional viral DNA synthesis

Explanation:

First of all, you must consider that the HSV has a double-stranded, linear DNA genome. Furthermore, the DNA skeleton is made of the 5'-3' phosphodiester bond. In other words, the 5-phosphat of a nucleotide will bond the 3' OH of the Deoxyribose (see image).

Therefore, if you add a molecule which lacks the 3' OH, such as acyclovir, and has a similar chemical structure to a regular nucleotide, the DNA polimerase will be able to add acyclovir to the main backbone of the viral genome. All in all, you'd be ''cheating'' the DNA pol.

Hence, wherever acyclovir was integrated, there won't be any chance to form a 5'-3' phosphodiester bond. The protomolecule will not be stable and will soon be degradated.

What is an advantage of using nuclear power?
My name is Ann [436]
<span><span>Large nameplate capacity per plant, typically around 1 GW.
</span><span>Typically 90% capacity factor, maximizing output from the nameplate capacity.
</span><span>Small fuel transportation volumes as the fissionable material just isn't that big or heavy compared to equivalent fossil fuel BTU sources.
</span><span>Low CO2 per MWH on a full life cycle basis. ~12 grams which is only slightly more than wind / solar.
This is a reason nuclear is a much better source for one of the major pressing problems of today than fossil fuels: global warming.</span>No particulate matter pollution.No sulfur dioxide or other chemical pollution.<span>Low fatalities per TWH. 
Nuclear is higher than renewables according to current statistics, but much, much lower than fossil fuel generation.</span></span>

Nuclear power generates lots of clean, stable energy.

Llamas have sexual reproduction. Some types of llamas have 74 chromosomes. That is how many chromosomes are in their somatic (bo
Sholpan [36]

Answer: 37 chromosomes.

Explanation: As is typical of mammals, llamas are diploid organisms, meaning that the number of chromosomes in each of their somatic cells is exactly twice of that found in the gametes (the so-called haploid number, referred to as "n"). If a particular species has 74 chromosomes in its somatic cells, we should expect to find 74/2=37 chromosomes in each gamete.

What enzyme places the nucleotides on the dna strand?
stepan [7]

Answer:

What is  DNA polymerase.

Explanation:

DNA polymerase enzyme is the enzyme That reads the code and synthesizes the appropriate nucleotide base pairs according to the matching nucleotide after DNA splits during the replication process.

It helps in making the DNA error-free by proofreading. DNA polymerase III which has 2 molecules that work on both the strand leading and lagging strand.
