Which is the correct sequence of the transfer of information in most organisms?

2 answers:

7 0

The formation of DNA is a sequential process. First, the DNA molecule is transcribed on to an RNA molecule. This RNA molecule carries the information from the DNA from the nucleus to the cytoplasm, where it encounters ribosomes. The ribosomes then read the information on the RNA molecules and construct a chain of amino acids corresponding to the codons on the RNA molecule. The amino acids combine to form a protein.
Therefore, the correct sequence is C, DNA to RNA to protein.

A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature

VMariaS [17]

Answer: The new pressure of the gas is (A) 854.46 kPa.

The pressure of a given mass of gas at the absolute temperature 110 degrees K is 400 kPa.

The temperature is raised to 235 degrees K with constant volume.

Therefore,

Initial pressure $P_{1}=400kPa$

Initial temperature $T_{1}=110K$

Final temperature $T_{2}=235K$

Final pressure $P_{2}=?$

According to pressure law of gas,

$\frac{P_{1} }{T_{1} }=\frac{P_{2} }{T_{2} }$ ( at constant volume) $P_{2}=\frac{P_{1}T_{2} }{T_{1} }$

$P_{2}=\frac{400X235}{110}$

$P_{2}=854.46kPa$

Thus, the required new pressure of the gas is 854.46 kPa.

marta [7]

Answer:

If temperature drops, it is negative feedback whereas if the temperature increases, it is positive feedback.

Explanation:

When the temperature drops from 98.30 °F, it means it is a negative feedback because its response is negative while if the temperature increases from 98.30 °F, it means it is a positive feedback because its response is positive. From 12 am to 3 am which represents negative feedback, temperature decreases whereas from 3 am to 6 am, the temperature increases which indicates positive feedback. From 6 am to 9 am, again the temperature drops and this fall represents negative feedback and so on.

Which processes are part of the fast carbon cycle?

wariber [46]

Carbon cycles from the atmosphere into plants and living things. For example, carbon is a pollutant in the atmosphere as carbon dioxide.
...
Photosynthesis. Plants pull in carbon dioxide out of the air through photosynthesis. ...
Decomposition. ...
Respiration. ...
Combustion.

I hope that this one is correct - C

Since transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

A plateau is made of sandstone of varying densities. How is the plateau likely to change over time? PLZZ ANSWER

il63 [147K]

First let me say this, i may be wrong. I think it would change over time because first of all the sandstone has different densities. Different kinds off rocks erode and get broken down by the wind at different rates. If its density is higher, it will take longer to erode

Besides lacking enzymes for rna editing describe how the lack of compartments in a prokaryotic cell results in a difference in g

777dan777 [17]

The first major difference between prokaryote and eukaryote gene expression is the location. Due to lack of compartments (nucleus) prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm (genetic material is located within the cytoplasm). So, transcription and translation in prokaryote occurs simultaneously. Gene expression in eukaryote occurs in both the nucleus (transcription) and cytoplasm (translation).

The steps of regulation of gene expression are also dissimilar, in prokaryotic cell, transcription is mostly the main point of regulation (eukaryote have transcription, post-transcription, translation, and post-translation regulation together with epigenetic regulation).
