Answer: Between 8 and 14
Explanation: Ammonia is an inorganic compound of formula NH₃. Also known as ammonium hydroxide, it behaves as a weak base.
pHydrion paper is a chemical test indicator, i.e., it indicates the pH of a substance.
If inserted in Ammonia, pHydrion will indicate a range of 8 to 14 because in pH scale, indication of base is over 8 and up to 14. The exact number depends on the hydrogen ion concentration of the substance.

Measure the mass of an empty container 2. pour the desired liquid in to
this container and wait for it to settle. 3. measure the mass of the
container + liquid 4. subtract the empty container mass to find the
liquid's mass Note: some scales have a tare feature (it defines a weight
of zero), which you measure the container's mass, use the tare option,
and then pour the liquid and wait for it to settle. Also, when you use a
scale, in truth you measure weight. It then divides by the known
gravity field to find a "weight" in kilograms, which we accept to equal
the mass in kilograms. You only truly measure mass when using a balance.
It compares the torque on the balance arm of the object's weight to the
torque on the balance arm of a slide-able weight. A balance will record
the same mass in any gravitational field.</span>
Explanation:
it should be sugar for what nucleotides contains
The correct answer is: cerebral cortex (prefrontal).
Cerebral cortex is the outer layer of cerebrum and it is the neural integration area of the brain. Globally, the role of cerebral cortex is role in memory, attention, perception, awareness, thought, language, and consciousness.
Prefrontal cortex is part of the cerebral cortex (cover the front part of frontal lobe). It is involved in complex social behavior of the human, complex cognitive behavior, decision making.
A challenge to traditional (pre-1860) ideas about species came from embryology, when it was discovered that embryos of dissimilar organisms, such as sharks and humans, resemble each other. Embryology involves the study of the formation and the development of an embryo and the fetus. It is one type of evidence of evolution such that the embryos of many different kinds of animals, mammals, reptiles, birds, fish among others, are similar showing a common ancestry.
