The role of the Golgi body or Golgi apparatus is to package the proteins in vesicles and target it to their respective place of function. Example, the receptor proteins that are synthesised in the Endoplasmic Reticulum will be sent to the Golgi body for its packaging into the vesicles that bind and fuse with the cell membrane. The targeting is done by the special set of markers present on the secreted vesicle. All the eukaryotic cells have a Golgi apparatus. When chemical treatment is done to stop its functioning, the cell stops functioning and eventually dies due to the hampered targeting of proteins to the various organelle. On the other hand, prokaryotic cells lack Golgi body as the cell size is small enough to allow for the synthesised protein to move by diffusion to its target. Hence no effect will be seen when prokaryotic cells are treated with that chemical.
Answer:
The correct answer is : the female chromosome
Explanation:
- According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
- RR is a genotype for Red eyes.
- A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
- In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
- Therefore, XX must represent another trait.
- By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
- Given XX genotype represent a female fruitfly chromosome.
You need two recessive alleles (xx). If even one dominant allele is present, the dominant trait will show (Xx or XX will both result in the dominant trait showing). That’s why they’re called dominant traits, because they overpower the recessive traits. In order for a recessive trait to show you must have two recessive alleles.
Answer:
(B) DNA instructs the building of various carbohydrates that provide energy for the cell (C) The DNA of an organism will dramatically change
Explanation:
Some advantages and disadvantages of growing tall as a plant are as follow: Tall, Growing tall can lead to larger amounts of wind pressure on its stalk so it can not stand up easily. More birds and other flying insects will be driven to land on it and feed on it. It also has less protection from things around it. Some advantages are it will get sun easier, it will be able to spread its offspring easier and it will not get trampled. Some advantages and disadvantages of growing short are as follows: Short, Growing short can lead to less animals able to feed on your fruit and spread your seed. They can be trampled easier and move things tend to hide in its flourish of leaves. It gets eaten by more since it is easier to reach. Some advantages, it will not have very much wind blowing on it at all times, it has protection from other elements because it is close to the ground.
