When a neuron carries the electrical potential of -70 millivolts, it is in the state called RESTING POTENTIAL. At the resting stage of the neuron, the inside of the neuron is 70 millivolts less than the outside. At this stage, there are more sodium ions outside the neuron and more potassium ions inside the neuron.
Answer: C. Shadow length decreased from sunrise to noon.
Explanation: Think about how the sun is positioned in the sky. If it was noon, the sun is above the stick which means little to no shadow at all. If the sun was rising, its hitting one side of the stick, making the shadow longer.

Answer:
a. Five-Carbon Sugar and Phosphate
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Answer:
Low Enzyme Production is the reason for no breaking down of food.
Explanation:
If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.
