Homologues are chromosome pairs of the same length, centromere position, and staining pattern with genes for the same characteristics at corresponding locations. One homologous chromosome is inherited from the organism's mother, the other from the organism's father during sexual reproduction. The crossing over, or synapse, occurs during meiosis, which is the process of gamete formation.
Answer:
The correct answer is option C. "arg+leu– or arg–leu+".
Explanation:
This bacteria is not able to growth on minimal medium or minimal medium supplemented with leucine. This means that the bacteria needs external supplementation of amino acids to growth, either arginine or leucine. Therefore, this bacteria can have the genotypes of arg+leu– or arg–leu+, meaning that the bacteria is able to synthesize either of two amino acids, but not both, because if that was the case the bacteria would be able to growth on minimal medium.
Answer:
0.1% will be available at the highest trophic level
Answer:
The correct answer is - A only.
Explanation:
The phospholipid membrane that is hydrophobic layer which permits movement of the molecules with the help of various transport protein or carrier proteins only if they are large or hydrophilic in nature such as water, however small molecules like hydrophobic molecules like lipids move through phospholipid by simple diffusion.
Rapid movement of the lipid is not need specific transport protein to cross phospholipid of the plasma membrane because of their hydrophobic nature. It also allows rapid movement in transport of the CO2 and Oxygen.
Thus, the correct answer is - A only.
