Answer: I think the answer would be (D) because mass and volume are kinda different and If one has a different volume then it would have a different mass right?
Answer:
none of the above
Explanation:
these can all cause air pollution
Answer:
Carbohydrates, particularly glycoproteins act as ligands for cell surface receptors.
Explanation:
Glycoproteins
- Glyproteins are conjugate molecules comprising of carbohydrates conjugated with proteins.
- Glycoproteins play a vital role in cell-cell recognition, pathogen recognition and and cell adhesion.
- Glycoproteins on the surface of pathogens act as prominent antigens for the immune system.
Glycoproteins in Fertilization:
Several glycoproteins are attached to the surface of the zona pellucida, the envelope of the oocyte. In humans, these have been termed as ZP1-4.
Glycoprotein-sperm interaction is one of the most crucial steps in fertilization. This receptor-ligand interaction ensures the entry of the sperm into the zona pellucida, the extracellular coat, covered in glycoproteins that surrounds the oocyte or egg.
Carbohydrate binding proteins present on the surface of the sperm recognize the glycoproteins on the zona pellucida (ZP). This enables them to adhere to the surface of the ZP and also to gain access to the oocyte.
Answer:
Breathing in human on land or during swimming or scuba diving, the human inhales oxygen and exhales carbon dioxide, These carbon dioxide molecules creates "air bubbles" that are then ousted into the water body. The diver at that point draws air from the pressurized air tank, and can inhale or breath. This permits the diver to remain submerged for any longer than only one inhale, and can travel deeper underwater.
Inside this framework, the Oxygen is primary input to the oxygen tanks, which are then utilized by the scuba diver. The diver would draw the oxygen from the tank considered as output in this system.
