I want to know full answer about ecoregion vs. ecosystem.
Answer:
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point).

Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Secondly, ecoregion boundaries rarely form abrupt edges; rather, ecotones and mosaic habitats bound them. Thirdly, most ecoregions contain habitats that differ from their assigned biome. Biogeographic provinces may originate due to various barriers, including physical (plate tectonics, topographic highs), climatic (latitudinal variation, seasonal range) and ocean chemical related (salinity, oxygen levels).
packaging methods of watermelon
Answer:
The packing process consists of:
The workers remove the watermelons from the bulk cardboard bins and place them onto the packing line.
The watermelons pass through three different brush steps (without the use of any wash water)

Tell me three things that you know about controlling microbial growth - think about how you handle certain foods in you home. Why is it so important to learn about how we can control microbes
1. Cooking food properly. Undercooked foods may still contain microorganisms that are harmful.
2. washing raw foods properly. It can remove thermophilic microorganisms which can't be inhibited by temperature.
3. Hands should be clean. Handling affects the most.
Its important to learn about controlling microbes because
microbes are everywhere and many are really harmful for other living beings. so,

Identify the effects of the vagus nerve on the following components of the digestive system Salivary glands Pyloric sphincter (gastric emptying) Smooth muscle in the gallbladder Smooth muscle in the duodenal papilla (sphincter of Oddi)
Answer:
Vagus nerve is the 10th cranial nerve. It is long start from brain and distributed over head, thorax and abdomen.
Explanation:
1. In the salivary gland the secretory and vasodilator effect on afferent nerve is mediated mainly by parasympathetic reflex which is given by vagus nerve.
2. Pyloric sphincter is the part present between the stomach and small intestine which regulate the flow of food particles from stomach to the intestine. Vagus nerve control the activities of pyloric sphincter. Vagus nerve help the pyloric sphincter to relax.
3. Efferent nerves of vagus nerve help the gall bladder to contract. Vagus nerve is stimulating the gastric tract to contract. So the vagus nerve stimulation promotpromotprthe production of CCK hormone and it will lead to the contraction and secretion of hormones from the gallbladder. Those contractions will help the gallbladder to empty the hormones from gallbladder.
4. The efferent nerves of vagus nerves act on the smooth muscles of duodenal papila. As above says it lead to the contraction of smooth muscles and also promote the production of CCK.

-an organ system
-multipotent.
-a tissue.
Answer:
The answer is B an Organ system
Answer:
an organ system
Explanation:
The correct answer is organ system. A tissue is a group of cells working together to achieve a common function. An embryo is a fertilized egg that has developed from a zygote. Multipotent merely refers to a type of stem cell that has limited specialization capabilities relative to the capabilities of totipotent and pluripotent cells.

ATP is a storable form of energy, while glucose is a usable form of energy.
o Glucose is a storable form of energy, while ATP is a usable form of energy.
Answer:
Glucose is the carbohydrate produced by photosynthesis. Energy-rich glucose is delivered through your blood to each of your cells.while glucose is a usable form of energy.
ATP is the usable form of energy for your cells.ATP is a storable form of energy
Explanation:
The difference between ATP and glucose, is glucose is a storable form of energy, while ATP is a usable form of energy. Thus, option D is correct.
What is ATP ?ATP or Adenosine triphosphate principal energy currency of the cell.
It is the byproduct of photophosphorylation, cellular respiration, and fermentation process. It is highly soluble in water.
Beside energy source, ATP have a role in signal transduction pathways and DNA synthesis.
Structurally ATP is a nucleotide which made up of adenosine molecule and three phosphate molecules.
The three phosphate molecules are connected by two phospho-anhydride bonds which releases huge amount of energy upon hydrolysis.
After hydrolysis of ATP is converted into adenosine diphosphate (ADP) energy is released.
In ATP hydrolysis, removal of one phosphate group releases 7.3 kilocalories per mole, or 30.6 kilojoules per mole.
Thus, option D is correct.

what is adaptation give any four characters of aquatic plants
Explanation:
Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.
1] Aquatic plants have leaves that float on the surface of water.
2] Thier leaves are rarely have stomata.
3] Thier leaves can perform all the work without xylem.
4] They are usually lack cuticle layer in order to avoid excessive dryness.
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.
Four characters of aquatic plants are as given below:
1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.
2) aquatic plants keep their stomata always open for they do not need to retain water.
3) on each side of their leaves are a number of stomata.
4) aquatic plants have less rigid structure since water pressure supports them.
