What is the main reason that it takes 2 to 3 minutes for the reaction to occur between sucrose and sulfuric acid in the dehydration of sucrose? the activation energy needs to be overcome in the reaction. the activation energy must be removed from the intermediates. the sulfuric acid has to be consumed before the reaction takes place. the sucrose molecules must rearrange to become the catalyst.

Answers

Answer 1

The main reason for this activity is the activation energy needs to be overcome in the reaction.

What do you mean by Dehydration?

Dehydration may be defined as a process where there is a removal or loss of water takes place from something.

When the reaction between sucrose and and sulfuric acid is carried, it may leads to dehydration of sucrose. As a result of this, activation energy requires to come up in the reaction.

Therefore, the main reason for this activity is the activation energy needs to be overcome in the reaction.

In roan cattle, red (R) and white (W) are codominant. Heterozygous individuals produce both red and white hairs, known as roan. When two roan cattle are crossed, what are the phenotypic ratios of the offspring

Answers

Answer:

1:2:1

Explanation:

To get the phenotypic ratios, first you must figure out the genotype results of the cross. If the two cattle both have RW, then you get 25% RR, 50% RW, and 25% WW.

This means you have 1 fully red cattle, 2 roan cattle, and 1 fully white cattle, or just simplified as 1 (red) : 2 (roan) : 1 white.

The ratio of red to white is 1:1, and the ratio of roan to non-roan is 2:1, which gives the phenotypic ratio of 1:2:1 for red:roan:white.

What is co-dominance ?

Codominance is a type of genetic inheritance in which both alleles of a gene are expressed equally in the phenotype of a heterozygous individual. This means that neither allele is dominant or recessive, and both contribute to the observable traits of the organism

When two roan cattle (Rr x Rr) are crossed, the possible genotypes of their offspring are RR, Rr, and rr. The phenotypic ratios of the offspring will be:

25% red (RR)

50% roan (Rr)

25% white (rr)

This is because both red and white alleles are codominant, meaning they are expressed equally in the heterozygous state (Rr) and produce the roan phenotype. The ratio of red to white is 1:1, and the ratio of roan to non-roan is 2:1, which gives the phenotypic ratio of 1:2:1 for red:roan:white.

Which statement best describes how organisms use DNA and amino acids to synthesize protein?
1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.
2 DNA is translated into mRNA, which is transcribed by the ribosome to produce an amino acid chain
3 Amino acids are transcribed into mRNA, which is translated into the nucleus to produce a molecule of DNA.
4 Amino acids are translated into mRNA, which is transcribed in the nucleus to produce a molecule of DNA.

Answers

Answer:

1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.

Explanation:

The steps of the process are always from DNA to mRNA to amino acids. This is because DNA can't travel out of the nucleus. So, DNA must be converted to mRNA to travel out of the nucleus. Only mRNA can leave the nucleus. The m in mRNA stands for messenger, so think of mRNA as the messenger from DNA to amino acids. Then the mRNA must be converted to amino acids to produce a protein.

So, options 3 and 4 are eliminated.

The process of DNA to mRNA is called Transcription. The act of transcription is called transcribing.

The process of mRNA to amino acid is called translation. The act of translation is translating.

The only option that fits this category is option 1.

The sun is a gigantic thermonuclear reactor that eventually fires huge amounts of concentrated radiation in the form of particles in a constant stream called the "solar wind".

A geomagnetic storm can last just a few minutes, or several hours, but the effects of geomagnetic storms can linger in the Earth's magnetosphere and atmosphere for days to weeks. The storm also results in a rapid drop in the strength of Earth's magnetosphere for a period of between 6 and 12 hours. Then the magnetic field gradually recovers over a few days.
