Answer:
The recombination frequency between two genes can not be more than 50 percent due to the independent and random assorting of the genes that are linked generating 50% recombination.
* Genes should be located far enough from one another so that crossover points can be made.
Example: Genes present at the 2 extreme ends of the chromosome.
* There should not be the linkage between the two genes due to linked genes go together. So no recombination happens.
It may be more than 50% if selected parents are heterozygous. But Mendel took homozygous parents. So, the maximum is 50%. There will be no recombinant if the two genes are linked.
Answer:
1. <u>Phosphoribosyl</u> amine
2. <u>glycinamide ribonucleotide (GAR), a formyl group</u>
3. F<u>ormylglycinamide ribonucleotide (FGAR), an amino group</u>
4. C<u>arboxyaminoimidazole ribonucleotide (CAIR), an amino group.</u>
Explanation:
1. <u>Phosphoribosyl</u> amine will accumulate in bacteria that lack glycine.
2. The intermediate <u>glycinamide ribonucleotide (GAR)</u> will build up in the absence of tetrahydrofolate.
N10‑Formyltetrahydrofolate donates <u>a formyl group</u> to the substrate
3. F<u>ormylglycinamide ribonucleotide (FGAR) </u>will accumulate in the absence of glutamine.
Glutamine donates <u>an amino group</u>
4.<u> </u>The intermediate <u>carboxyaminoimidazole ribonucleotide (CAIR)</u> will accumulate when aspartate is lacking.
Aspartate donates <u>an amino group.</u>
All 3 farming techniques are methods of soil conservation.
Contour plowing is used to stop water from flowing directly down slope to prevent gullying.
Terracing is used to slow the amount of runoff, and prevents rapid soil erosion.
Strip Cropping is when farmers plant plants in alternating bands to stop soil erosion.
The answer would be D) The growing population is taxing Earth’s resources which could lead to the extinction of many species (I just got this right)
A. And B.
Maltose or as known as malt sugar is a disaccharide combined by a dehydration reaction with two glucose molecules.
The most known disaccharide is sucrose or commonly known as table sugar which is made of the monomers glucose and fructose.
