Answer:
A. C4H8C4 - NOT
B. C12H12C4 - NOT
C. CóH1206 - yes
D. C4H2020 - NOT
Explanation:
Carbohydrates are one of macro molecules made up of carbon, hydrogen and oxygen. These are essential molecule as they provide nutrition and makes structural component in plants too.
The ration of carbon, hydrogen and oxygen is similar in almost every sugar or carbohydrate which is 1:2:1, one carbon molecule and one oxygen molecule per two molecule of hydrogen.
In choice A, and B have no oxygen molecule so they can not be carbohydrate, where as D have inappropriate ration in comparison to the carbohydrates.
Thus, the correct answer is :
A. C4H8C4 - NOT
B. C12H12C4 - NOT
C. CóH1206 - yes
D. C4H2020 - NOT
Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.
The answer is C, glacial till soil. Glacial till is a mixture of coarse clay and rock particles according to the reading.
Answer:
Greater on Jupiter
Explanation:
Gravity depends on mass. Jupiter has more mass than Earth so its gravity is two and a half times greater. Therefore a person will weigh more on Jupiter.
