Answer:
Explanation:
Reactants
Solid 'iron'III'oxide' = Fe₂O₃
'carbon'monoxide'gas' = CO
Product
'iron'metal' = Fe
carbon'dioxide'gas = CO₂
Now
Fe₂O₃
+ 3CO
→ 2Fe + 3CO₂
The reactants are positioned at the left hand side of the equation.
The products are at the right hand side
s = solids
g = gases
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.
Answer:
The correct answer is motion.
Explanation:
Lipids are the important constituents of plasma membrane. For example phospholipid,glycolipid,splingolipid,cholesterol builds most of the structural framework of the cell membrane.
Lipids plays an important role during cell signaling For example the phosphotidy inositol 4,5 bisphosphate one of important component of the inner leaflet of the the plasma membrane undergo hydrolysis to form Diacylglycerol(DAG) and inositol triphosphate(IP3).Both IP3 and DAG act as second messenger.
Lipid act as an insulator of myelein sheath that helps in the saltatory conduction of nerve impulse across the axon of unmyelinated nerve fibre.
Lipid does not involve in motion
Answer:
Paranthropus robustus
Explanation:
2.5 million years ago some autralopithecines were identified by dating fossils from South Africa, meaning they lived a good period of time. Of these, Australopithecus africanus is well known and is a little closer to our species. Other fossils found in excavations in both southern Africa and eastern Africa have been found to be of more recent specimens 2.5 to 2 million years ago. These specimens were classified as Paranthropus robustus and Paranthropus boisei. These australopithecine species became extinct and left no current descendants.
