The answer for the question is Migraine<span>. Migraines Headaches are extremely, nearly paralyzing headaches that are located on one side of the head and are sometimes accompanied by dizziness, nausea, or vomiting. They normally develop in two phases; The first phase, in which blood vessels in the brain narrow (vasocontsriction), such that the flow of blood to arts of the brain is reduced. Second phase; occurs when the blood vessels expand, such that blood flows through them rapidly, thus stimulating many neuron endings and causing pain. </span>
Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).
Answer: The following which is not true is letter A.
Explanation: Because microtubules require GTP hydrolysis. The process requires energy from GTP hydrolysis. It occurs at the beta- tubulin subunit after incorporation of the tubulin dimer into the microtubule lattice.
Answer:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.
