Answer:
C. They are carried by motor proteins using the cytoskeleton as a "roadway"
Explanation:
Vesicles hitch a ride on molecular motors such as kinesin or myosin, moving along the cytoskeleton until they reach their intended location, where they then fuse with the target membrane or organelle. Typically, vesicles progress from the ER to the cis Golgi, followed by movement from the cis to the medial Golgi, from the medial to the trans Golgi, and finally from the trans Golgi to the plasma membrane or other cellular compartments. While the predominant direction is forward, there are also vesicles that return from the Golgi to the ER, carrying proteins that should have remained in the ER (e.g., PDI) that were inadvertently enclosed in a vesicle.
Answer:
c. Would not conform to the 9:3:3:1 phenotypic ratio
Explanation:
When two genes are located close together on the same chromosome, the F2 generation's phenotype would not align with the 9:3:3:1 ratio.
Genes that are closely located on the same chromosome are known to be linked, and they exhibit a higher frequency of recombination compared to those that are not linked.
Consequently, while independently assorting genes yield a 9:3:3:1 phenotypic ratio in F2, linked genes do not assort independently, resulting in deviations from the expected standard phenotypic ratio.
The right option is c.
Answer:
Explanation:
Various materials will respond to heat differently, altering their temperature at distinct rates, due to the differing heat absorption capacities of these materials.
Response:
Termites contribute to the formation of mounds which help in soil aeration and moisture retention, aiding the growth of various plants such as shrubs, grasses, and trees.
Their mounds, along with the droppings, supply phosphorus and nitrogen, enriching the soil and promoting the growth of grasses, shrubs, and trees.
Reasoning:
These insects are prevalent in the Savanna regions of Africa and construct mounds from their feces, saliva, and soil.
