The scenario that supports the "one gene-one enzyme" hypothesis of metabolic disease causation is Phenylketonuria (PKU). This disease (PKU) is caused by the failure to produce a functional variant of an enzyme.
Phenylketonuria (PKU) is a metabolic inherited disorder associated with a decreased metabolism of the amino acid phenylalanine.
PKU is caused by a mutation in the gene responsible for encoding a key enzyme needed to break down phenylalanine.
Untreated PKU may lead to diverse health problems which include brain damage, intellectual disability, seizures, mental disorders, etc.

what is responsible for changes in the state of matter?
and how are
the molecules of a liquid different from that of a solid? PKSS HELOOOÑLPPPP
Answer:
Temperature and pressure are the two factors which are responsible for change in state of matter.
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.

1. The equation representing the equation is ~
[tex] \mathrm{Na + Cl\rightarrow NaCl}[/tex]
The given reaction is a redox reaction because there's a transfer of electron from Sodium (Na) to chlorine (Cl)
where sodium is oxidized (due to loss of electron) and chlorine get reduced (due to gain of electron).
2. Sodium is a highly reactive element which belongs to the 1st group of periodic table, hence it can catch fire if it is kept free in atmosphere. so in order to prevent that it is stored in kerosene oil, which doesn't let Sodium come in contact with air .

What evidence is there to support the theory that strong nuclear force is greater than electromagnetic force?
A: Electrons are attracted to protons.
B: Protons repel other protons.
C:The nucleus holds the protons together.
D:Protons and neutrons are attracted to each other.
Answer:
The electromagnetic force is a long range force which acts of charged particles. Like charges repel and unlike charges attract. ... The strong nuclear force is very short range and can only bind adjacent protons and neutrons. The electromagnetic force is long range.
Explanation:
is it true or false when the there are too many protons making the nuclei unstable, it will undergo a positron decay and a proton will turn into a neutron.
Answer:
True
Explanation:
As the number of protons in the nucleus increases, the number of neutrons needed for a stable nucleus increases even more rapidly.

Explanation:
a person dies, and within hours, the skeletal muscles develop a locked contraction known as rigor mortis. calcium ions leak from the sarcoplasmic reticulum into cytoplasm. from your knowledge of cross bridge cycling, what best explains this rigor?
Rigor mortis is the stiffening of the body after death. After death, the body begins to get cold. From about two to six hours after death, the muscles start to stiffen, probably because the actin and myosin filaments of the muscle slide into each other. The rigor mortis starts at the eyelids, jaw and neck and then slowly spreads to all parts of the body within six hours.
Contrary to popular belief, rigor mortis will occur more quickly in high ambient temperatures than in cold conditions. This is because the underlying chemical reaction occurs faster at higher temperatures.

Which hybrid orbitals overlap to form the sigma bonds between the indicated atoms in xanthine?
Many nitrogen and carbon atoms can be found in the structure of a heterocyclic molecule called xanthine, which is present in many biological systems.
The development of a sigma bond between these atoms is an essential component of its binding. A special example is the sigma bond between the nitrogen atom and the neighboring carbon atom. In the context of this sigma bond, the hybridization state of nitrogen can be either [tex]\rm sp^2[/tex]or [tex]\rm sp^3[/tex], and the hybridization state of carbon can be [tex]\rm sp^3[/tex]. A sigma bond is formed when the hybrid orbitals of carbon and nitrogen, which are each [tex]\rm sp^2[/tex] hybridized and [tex]\rm sp^3[/tex] hybridized, overlap. A strong covalent bond can develop when the [tex]\rm sp^2[/tex] hybrid orbitals of nitrogen and carbon line up. This allows electron sharing.
