Increasing the stimulation up to the maximal stimulus
Answer:
Plant cells have a cell wall and chloroplasts and the cell wall gives the cell a rectangular shape unlike animal cells which have a round shape because we only have a cell membrane.
Answer:
0.146 g
Explanation:
Given data:
Volume of solution = 100 mL
Molarity = 10 mM
Molecular formula = C₇NH₁₆O₂
Mass of C₇NH₁₆O₂ needed = ?
Solution:
First of all we will convert the mM into M and mL to litter.
Volume of solution = 100 mL
Volume of solution = 100 / 1000 = 0. 1 L
Molarity = 10 mM
Molarity = 10 / 1000 = 0.01 M
Molar mass of C₇NH₁₆O₂ = 146.21 g/mol
For 1M solution we dissolve 146.21 g/mol in one litter
For 0.01 M
146.21 g/mol × 0.01 mol/ L = 1.4624 g/L
while we have to make 0.1 L solution,
1.4624 g/L ×0.1 L = 0.146 g
Answer: Substances that are protein based cannot cross the lipid cell membrane, but can exert their effect by binding to the proteins based receptors present on the lipid bilayer.
Explanation:
Hormones such as calcitonin , Parathyroid hormone and pituatry horomones are proteins and water soluble.They cannot cross lipid bilayer but can bind to ligand binding protein receptors.
These receptors are protein macromolecules that are specific in nature for specific hormones.
After binding to the receptors, these hormone-recpetor complexes activate second messengers and regulate the downstream effects.
