Explanation:
Palaeontologists study the fossil and once they found that the fossil of an organism in layer 2 and 3. The fossil present in layer 3 is very similar to the fossil present in layer 2.
From this, it could be concluded that the layer 3 possible might be evolved from the fossil present in layer 2. The fossil of layer 3 might be a close relative of the extinct fossil of layer 2 as they could have shared a common ancestor.
Many possibilities could be explained but these two are more valid.
The right answer is NADP+.
Ferredoxin is an iron-sulfur protein that effects electron transfer in a large number of redox reactions in cell metabolism through Fe-S clusters whose iron cations oscillate between +2 (ferrous) oxidation states. and +3 (ferric). The first protein of this type was isolated in 1962 from the anaerobic bacterium Clostridium pasteurianum. A chloroplast-specific ferredoxin is involved in the cyclic and noncyclic photophosphorylation reactions of photosynthesis. In non-cyclic photophosphorylation, ferredoxin is the ultimate electron acceptor and reduces NADP + under the action of ferredoxin-NADP + reductase (EC 1.18.1.2) with FAD and a flavin group as cofactors:
2 ferredoxin- [Fe (2+) Fe (3+) S2 (-2)] + NADP (+) + H (+) ==> 2 ferredoxin- [Fe3 (+2) S2 (-2)] + NADPH .
Answer:
True
Explanation:
All living things have more than one cells that help function the organ system
1. Having a sickle cell anemia crisis is a severe condition of reduced red blood cell count.
2. Having sickled red blood cells lead to the symptoms like having pain in the chest and the throbbing of her leg.
3. A person having sickle cell anemia is mostly tired due to reduction in red blood cells, so they cannot do any work with their bodies. There would difference in the personal appearances like yellow eye and skin looks pale and the skeletal system become weak too. There is trouble with breath too.
4. The symptoms are as follows like the patient fall in to anemia condition, urine is dark in color, eyes are yellow, and person looks pale and the body experiences frequent pain and delay in the body growth.
5. Hydroxyurea is the medication used here. The pros of this are the frequent body pains reduces and reduction in need of blood transfusion. the cons are increase of infection and this particular drug may cause tumors and leukemia.
Answer:
Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.
Explanation:
Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.
