Answer:

When you eat food the body’s digestive system breaks down the protein into the individual amino acids, which are absorbed and used by cells to build other proteins and a few other macromolecules, such as DNA. Let’s follow the specific path that proteins take down the gastrointestinal tract and into the circulatory system.

A dihybrid cross produces 30 recombinant offspring out of a total of 1,000 offspring. What is the recombination frequency of the
uranmaximum [27]

The recombination frequency of the two gene pairs is 3%.

The number of recombinant offspring(r.o.) / total number of offspring x 100% = recombination frequency(θ):

r.o./total x 100% = θ

30/100 x 100% = 3%

Recombinant offspring are children that have a different allele combination to their parents.

For example, say a mother has a haploid cell with the alleles AB and the father has a haploid cell with the alleles ab. These combine to make a diploid cell with the sequence Aa+Bb.

Formation of Recombinant Offspring :

Recombination can happen in two different ways; independent assortment and crossing over.

  • Independent assortment is when the maternal and parental DNA are mixed during meiosis, creating a new gene sequence.
  • Crossing over happens during the first stage of meiosis when the two homologous chromosomes are paired and a portion breaks off on the same loci then reconnects to a different end. Crossing over can only happen when there isn't a physical linkage of the parental alleles.

Recombination frequency (θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis. A centimorgan (cM) is a unit that describes a recombination frequency of 1%. In this way we can measure the genetic distance between two loci, based upon their recombination frequency. This is a good estimate of the real distance. Double crossovers would turn into no recombination. In this case we cannot tell if crossovers took place. If the loci we're analysing are very close (less than 7 cM) a double crossover is very unlikely. When distances become higher, the likelihood of a double crossover increases. As the likelihood of a double crossover increases we systematically underestimate the genetic distance between two loci.

When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

2. What is needed from fermentation to restart glycolysis?​
Shalnov [3]
How cells extract energy from glucose in the absence of oxygen. In yeast, anaerobic reactions produce alcohol, while in your muscles, they form lactic acid.





Both processes can happen thanks to alternative glucose degradation pathways that occur when normal cellular respiration that uses oxygen (aerobic) is not possible, that is, when there is no oxygen available that acts as an acceptor at the end of the transport chain of electrons. These fermentation pathways include glycolysis with a few extra reactions at the end. In yeast, the extra reactions produce alcohol; in the muscles, lactic acid.
Fermentation is a widespread route, but it is not the only way to obtain energy from fuels anaerobically (in the absence of oxygen). Some living systems use a different inorganic molecule instead of

How did the number of organisms change between 1900 and 2010
elena55 [62]

Answer:

the number of prey and predators has decreased

Explanation:

this is because of increased rate of hunting .the prey such as elephants and rhinos are being hunted for their horns while predators are also being hunted because of their skin.

also due to man and wild animal conflicts which happen in areas nearing the forests ,both prey and predators are killed.
