Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.
Answer:
Explanation:
b. Based on the graph, the molar concentration is -0.32 M.
c. When water moves from areas with high water potential to areas with low, the phloem cells accumulate sugars. This results in transpiration.
Answer:
Cell–cell interaction
Explanation:
Based on the scenario being described it can be said that the developmental process that has most likely been affected are known as Cell–cell interaction. These are the direct interactions that exist between cell surfaces that allow them to communicate with one another. Doing so by receiving signals and initiating transduction pathways. Therefore since these are functions that have been disrupted it's safe to say that the Cell-cell interaction has been affected.
Answer:
1. ionic bonds;
2. salt
Explanation:
Ionic bonding is a case of chemical bond that produces two oppositely charged ions, it occurs where there is the complete transfer of valence electron(s) between atoms. In the case of ionic bonds, the metal loses electrons to become a positively charged cation, and the nonmetal receives the electrons to become a negatively charged anion.
While salt is a mineral that is comprised mainly of sodium chloride (NaCl)
Two unicorns with no horns could have an offspring if the horn trait is recessive and the no-horn trait is dominant. There would be a 25% chance of the offspring from these two unicorns having a baby unicorn with a horn.
