Answer:
The correct answer is-ER Golgi plasma membrane
Explanation:
Rough endoplasmic reticulum contains the ribosomes on it which helps in the formation of proteins from the mRNA by the translation process. The proteins chains synthesized are pushed in the cisternae of the RER where the primary modification of proteins takes place.
Then these proteins are released towards closely associated Golgi apparatus where the further modifications and processing of proteins takes place like glycosylation, sulfation, etc.
After the modification, the proteins are released from the Golgi in enclosed vesicles to their destination like they can be sorted in plasma membrane or lysosomes. So the correct answer is-ER > Golgi > plasma membrane.
Answer:
D. Sterility Locus
Explanation:
Angiosperms have several mechanisms to prevent self-pollination due to the advantage of cross-pollination. One of such mechanisms is self-incompatibility genes present on the sterility locus.
These genes determine the germination of the pollen on the stigma. If both the pollen and stigma carry the same allele of the gene present at the sterility locus, the germination of pollen is prevented.
The sterility locus has multiple alleles and the presence of the same alleles at the same locus in both pollen and stigma prevents the pollen germination.
For example, pollen from S1S2 individuals can not germinate on the stigma with the S1S3 genotype. Here, the pollen does not obtain water as required for germination from the stigma and are unable to germinate.
Radiology is the filed that includes CAT (computerized axial tomography) scans and MRI (magnetic resonance imaging) scans as diagnostic tools.
Radiology is the science that uses x-rays or other forms of energy to create images for diagnosis. It can also be used for therapeutic intent. It has a variety of techniques such as x-ray imaging, ultrasound, MRI, CT scan and PET imaging. The acquisition of images is done by the radiographer or also known as radiologic technologist. These images are then interpreted by a diagnostic radiologist, a doctor who is trained to read or interpret the images and produce a report of their findings and impression or diagnosis.
One characteristic of life is that living things have different levels of organization
-They have both molecular and cellular organization
- They must have the ability to organize simple substances into complex ones.
- They organize cells at several types of levels, namely:
(a) Tissue- a group of cells that perform a common function
(b) Organ - A group of tissues that perform a common function.
(c) Organ system- a group of organs that perform a common function.
(d) Organism- any complete living thing.
