The most leaching of minerals occurs from the Horizon A(the top layer) into the horizon B(the sublayer) The zone B which is commonly referred to as the subsoil layer is the zone of accumulation where rain water percolating through the soil from the top layer and it is precipitate within the subsoil(horizon B)
Answer:
The option c is partly correct.
Explanation:
None of the statements is completely accurate because:
a. Saurischian dinosaurs include theropod and sauropod dinosaurs, and their common ancestors. Ornithischians comprise neornithischians (ornithopods and ceratopsians), thyreophorans (ankylosaurs and stegosaurs) and heterdontosaurids.
b. Capability to fly has only been documented in fossils belonging to Saurischia (where the birds are also classified in). Feathers, on the other hand, do appear in the two clades. Feathers, however, are not a trait exclusively associated to flight.
c. This is a correct comparison between ornithischians and saurischians in the sense that the attributes do belong to these clades, but when comparing animals there most be a comparison that reflects a pattern. Ornithischians have leaf shaped teeth suited to eat plant material, whereas saurischians have teeth for a carnivore and herbivore diet.
d. Sauropods are saurischians and they evolved herbivory from a meat-eater ancestor.
Answer:
microvilli
Explanation:
having microscopic projections called microvilli. The epithelial cells of the proximal convoluted tubule are adapted.
Answer:
Option (c).
Explanation:
Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and transcription factors. The transcription occurs in 5' to 3' direction.
Post trancriptional modification occurs in the RNA molecule that plays an important role in transcription as well as translation. The introns are removed from the RNA transcript and exons joined together is known as splicing. The alternative splicing occurs in which different protein isoforms are formed by the single exons.
Thus, the correct answer is option (c).
Answer;
The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
Explanation;
-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.
-The process takes place in two phases; light dependent stage and light independent stage.
-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.
-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
