Like DNA, RNA contains four nitrogenous bases. Three of them are the same as those found in DNA. The one that is different is called uracil. The five-carbon sugar in RNA is called ribose.
Uracil is a crystalline organic molecule, and a component of the ribonucleic acid (RNA). The RNA molecule is made up of a sequence of nucleotides, which individually contains a five-carbon sugar (ribose), a nitrogenous base, and a phosphate group. Uracil is one of the four nitrogenous bases present in the nucleic acid of RNA. The others are adenine, cytosine, and guanine, and are represented by the letters; A, G, C and U. In DNA (deoxyribonucleic acid), the uracil nucleobase is substituted by thymine.

The best and most correct answer among the choices provided by the question is the third choice "neap"
Neap tides<span> occur twice a month when the sun and moon are at right angles to the Earth. When this is the case, their total gravitational pull on the Earth's water is weakened because it comes from two different directions.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
So naturally, Water loves to be with water. This is just a common knowledge of biology. The side with the least amount of water will recognize that the opposing side has more water. Water molecules in Side A will essentially try and cross the selectively permeable membrane and go onto the crowded side. This will make the Cell in A become lysed and it will shrink. Your answer will be:
C. The Water level will increase on side B and decrease on Side A until concentrations are equalized.
<span>4. The neurons that carry impulses from the eyes to the spinal cord and brain are called the Sensory neurons. Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
5. Motor neurons carry impulses from the brain and spinal cord to and from the Muscles and glands. The motor neurons transmit impulses from the spinal cord to skeletal and smooth muscles, and therefore directly control all of our muscle movements. There are two types of motor neurons, those that travel from spinal cord to muscle (lower motor neurons) and those that travel between the brain and spinal cord (upper motor neurons)
6. The neuron's cell body has short, branched extensions called dendrites. Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface are of the cell body. They receive information from other neurons and transmit electrical stimulation to the soma (cell body). They are also covered with synapses.
7. In most animals and of different neurons are clustered in bundles called nerves Axons and dendrites. Axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal. The larger the diameter of the axon, the faster it transmit information. Most neurons have only one axon, they transmit impulses from the cell body and also may or may not have a myelin covering.
8. The insulating membrane that surrounds a single axon in some neurons is called the Myelin sheath. The myelin sheath is a protective covering that surrounds fibres called axons, the long thin projections that extend from the main body of anerve cell or neuron. It is composed of proteins and lipids. The main function is to protect and insulate these axons and enhance their transmission of electrical impulses.</span>
