Answer:
Dead plant matter
Explanation:
Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.
Answer:
geologists use rock samples and direct evidence to prove what earth's structure is like.
Explanation:
Answer:
There are many green house gases and carbondioxide is one of them. Green house gas has the ability to stop the heat from going to the atmosphere. This heat energy reduces the atmospheric carbondioxide to dissolve in the ocean water so more concentration of carbondioxide is present in the atmosphere which stop the reflected sunlight rays into the space and thus increase the temperature of the earth surface. This increase in temperature called global warming.
Answer:
The creation of the limbs is carried out by AER and ZVP. AER stands for apical ectodermal ridge and ZVP stands for polarising activity line.
Explanation:
- AER is responsible for the developmental progression in the distal to the anterior region and the ZVP is liable for the progressive advancement in the posterior to a backward region.
- AER and ZVP are interconnected on one another in the secretion of a sonic hedgehog, which eventually assists throughout the hox speech to promote the growth of the arm.
- The hypothesis that the new short-arm gene inhibits the effect of FGF (fibroblast growth factors) on AER can be tested and use a template of cultured cells.
- The AER may be disrupted in the model and the impact of the gene encoding on FGFs may be examined. If in the existence of a viral vector, the role of the FGFs is to trigger correct growth, then the hypothesis is incorrect, or else the hypothesis is right. The FGF8 is by far the most powerful of all as the result.
Answer:
They travelled over 2000 miles by sea is exceptional about the role of early Polynesian cultures in exploration
Explanation:
These people have the exceptional talent having the excellency in boat making. And have the ability to sail across the sea with the help of currents, stars and with cloud formation. They have excellency with the highest skill in fishing and farming. Growing of fruit trees, growing of vegetables that also includes the growing of pigs, poultry and dogs. Islanders were having the talent of craftspeople, and cravings of wood, fibre and feathers for creating pieces of power and beauty.
