Answer:
C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.
Explanation:
The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.
The heterozygous plant Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).
- Dr: parental
- dR: parental
- DR: recombinant
- dr: recombinant
To calculate the frequency of each type of gamete, we must use the formula:
Distance (map units) / 100 = frequency of recombination.
18 mu / 100 = 0.18.
The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.
The frequency of parental gametes will be:
1 - frequency of recombinant gametes
1 - 0.18 = 0.82
But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.
Answer:
B.
Organisms use some of the energy they take in for life process... Like respiration, thermoragulation, etc
Answer:
The phosphate head of the phospholipid is hydrophilic because it is polar (having charge), and thus readily dissolves in water which is a polar solvent. The hydrocarbon chain tails of phospholipid are hydrophobic because they are nonpolar (uncharged), and thus remain undissolved by water. These hydrocarbon tails have an affinity for each other, orienting themselves to face each other in water, forming the hydrophobic …

Answer:
basically "building blocks"
Explanation:
Living things are made up of very large molecules. These large molecules are called macromolecules because “macro” means large; they are made by smaller molecules bonding together. Our body gets these smaller molecules, the "building blocks" or monomers, of organic molecules from the food we eat.
Explanation:
During cellular respiration, glucose is broken down and energy is released in the process.
- Cellular respiration is a metabolic process by which energy is produced.
- In this process, chemical energy stored in the chains of the glucose atoms are transformed into heat energy.
- In cellular respiration, glucose combines with oxygen.
- The product is the formation of carbon dioxide and water with the release of energy.
- This energy is stored in form of ATP.
- To be released, one Phosphate is detached to produce ADP.
