Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
Answer:
Due to the presence of suitable environment.
Explanation:
Suitable environmental conditions are responsible for the presence of large amount of species in water bodies because suitable environmental conditions provides necessary materials for the growth and survival of organisms. The marine environment that have sufficient amount of food, space, optimum temperature, pH and salt concentrations so in this environment more number of species are present due to increase in population as compared to those ecosystem having harsh environmental conditions.
In a food web grass is a producer because grass isn't a predator or prey it gives energy to herbivores then herbivores transfer energy to predators then carnivores eat both
Confidence interval (CI) mean upper (+) and lower (-) value of z(s/square root of n)
CI + / - z(s/square root of n)
As we known that at 98% CI the z value is 2.054 (see attached tables)
therefore
189 + / - 2.054 (7.3 / square root (9) )
189 + / - 2.054 (2.433)
189 + / - 4.997
Therefore
CI= 189 – 4.997 OR 189 + 4.997
OR
CI= 184.003 to 193.997
According to the question’s requirement CI round to 1 decimal
CI= 184.0 to 194.0
The blood.
Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system so that it can be removed from the body.
