There are 20 standard amino acids. Ninhydrin turns yellow when it interacts with proline. Ninhydrin turns purple in the presence of the other 19 amino acids. Can you determine the identity of each of these 19 amino acids using ninhydrin test only? why or why not
Because the ninhydrin test produces the same purple color for all amino acids except for proline, it cannot be used to identify all other 19 amino acids.
What are amino acids?Amino acids are the molecules from which proteins are made.
Amino acids contain an alpha amino and carboxyl group, with a side chain group attached.
The ninhydrin test is used to test for the presence of amino acids generally and for proline specifically.
Since the ninhydrin test produces the same purple color for all amino acids except for proline, it cannot be used to identify all other 19 amino acids.

One function of the poly-A tail on eukaryotic mRNA sequences is to help the mRNA
be transported from the nucleus to the cytoplasm. Prokaryotic mRNA also has a
poly-A tail. Choose the best explanation of the prokaryotic poly-A tail.
A. Prokaryotic poly- A tails aren’t important, because prokaryotes don’t have nuclei
B. Prokaryotic poly A tails have the same functions as eukaryotic poly-A tails, because this process is highly conserved throughout different species.
C. Prokaryotic poly A tails are composed of a different molecular structure compared with eukaryotic poly- A tails
D. Prokaryotic poly- A tails have other functions, because prokaryotes don’t have nuclei
Answer: D
Prokaryotic poly-A tails have other functions, because prokaryotes don't have nuclei.
Explanation: It's an extension of the prokaryotic cell, because of its lack of a nucleus.
If a mineral can scratch fluorite and it can be scratched by a knife what is the hardness of the mineral
Answer:
The hardness rating is 4.
Explanation:
Calcite sits at a hardness rating of 3 and is very easily scratched with a knife and/copper coin. This is where most Marbles, limestones, travertines, rate.
Meanwhile, Fluorite sits at hardness 4 and can be scratched by a knife.

What is DNA?It should be noted that deoxyribonucleic acid, is the hereditary material that is found in humans and all other organisms.
DNA replication is a complex process that involves many enzymes and the complex formed by the enzymes to make an exact copy of the DNA during cell division. DNA replication enzymes are common in both prokaryotes and eukaryotes but the site of DNA replication differs.
The difference between prokaryotic and eukaryotic DNA replication is that the prokaryotic DNA replication takes place through a single origin of replication. In contrast, eukaryotic DNA replication occurs through multiple replication origins.
The nucleus is an organelle that carries the genetic material of the cell. Therefore, DNA replication does not take place in the nucleus but in the cytoplasm.
In conclusion, the label that would change if this DNA process took place in a prokaryotic cell is the nucleus.

The Venn diagram comparing the characteristics of the Sun, Earth and Moon the item in section B would be that the moon and the earth reflect light and have a rocky composition.
The moonThe moon is a natural satellite of planet Earth. She is the only celestial body to receive human beings.
The SunThe Sun is large and contains a lot of hydrogen, being held by strong gravity. As a result, the pressure and temperature inside are very high, causing hydrogen atoms to collide with each other, in what we call nuclear fusion, and generate helium.
Planet EarthPlanet Earth is a group of millions of structures of living organisms that hold the power to preserve life. The Earth formed about 4.5 billion years ago, is located in the middle of the Milky Way, being the third-closest planet to the Sun and the fifth largest among all the planets that make up the Solar System.

Why do we wear white or light coloured clothes in summer?
Why do we wear black or dark coloured clothes in winter?
Answer:
Why do we wear white or light coloured clothes in summer?
We wear white or light coloured clothes in summer because white coloured clothes reflect most of the sun's heat and absorb very little of the sun's heat and keeps our body cool.Why do we wear black or dark coloured clothes in winter?
We wear black or dark coloured clothes in winter because black coloured clothes absorb most of the sun's heat and keep our body warm.Explanation:

[tex]\bold{\huge{\orange{\underline{ Answers }}}}[/tex]
Answer 1 :-In summer we generally prefer white or light coloured clothes because :-
Light or white coloured clothes are bad absorber or a good reflector of heat . So when light rays falls on any white or light coloured clothes. they reflect that rays and absorb negligible of it . Light or white coloured clothes also allow the heat to escape from your body which makes you feel cool for a long day . Light or white coloured clothes are also act as a good absorber of sweat so when people sweat .Then as a good absorber , they absorbs it and you will feel coolAnswer 2 :-In winter we generally prefer dark or black coloured clothes because :-
Black or dark coloured clothes are good absorber and bad reflector of heat. When light rays falls on any black or dark coloured clothes it absorbs all the heat especially black coloured clothes. This happens because different colours have different wavelength. On the other hand, black colour has the ability to absorb all different types of wavelength of visible colour that is why it act as good absorber. The black or dark coloured clothes absorb all the heat and allow negligible heat to escape and due to this our body feels warm It is also act as good soaker of sweat just like white coloured clothes.Which statement is true about wood
