Answer:
Plant hormonal regulation differs from animal hormonal regulation in that there are no dedicated hormone-producing organs in plants as there are in animals.
Explanation:
<em>Plant hormones control different functions in plants such as growth and development.</em> These hromones are signal molecules that affect gene expression and transcription levels. What diferentiates them from animals is that in plants there are no dedicated hormone producing organs. For example, that plants and insects produce their hormones differently.
A large assortment of plant dispersal mechanisms.
Explanation:
Pretty much everything can be explained about Australia, as to where it was in the past, with which other large landmasses it was connected, its flora, its isolation from the other continents... One thing that still needs explaining is the large assortment of plant dispersal mechanisms, which is not typical for well established islands.
The reason as to why this is weird and hard to explain is because the well established islands have flora that is well adapted to their living conditions, and also it lacks competition from outside. In other words, they rule the place. The plants in Australia though exhibit dispersal mechanisms that are typical for the plants of the continental masses that are connected, so it causes big problem in explaining it.
Answer:
i think its 1%
Explanation:
if the grass has 100% energy and only 10% gets passed do that two times and you should have 1% since 1 x 10 is 10
Answer:
Due to the cost and resource input (specially the land) required for producing ethanol
Explanation:
In current time most of the ethanol is produced by fermenting corn, sugarcane or other plants at high temperature. In this process of fermentation, liquid bio fuel is produced.
These plants and crops require large area for cultivation and production along with huge inputs of fertilizers and water. As per an estimate , 3 gallons of ethanol require bushel of corn that intakes 800 gallons of water which is a huge cost to any nation or individual
Hence, scientist are finding new ways to create ethanol
Answer:
Blood flow to the liver is unique in that it receives both oxygenated and (partially) deoxygenated blood. As a result, the partial gas pressure of oxygen (pO2) and perfusion pressure of portal blood are lower than in other organs of the body.
