Answer: positive feedback mechanism

Explanation:the body is able to regulate it's internal environment through homeostasis.it usually involves a receptors,an intergration center and an effector.

In positive feedback,the body enhances the initial stimuli and pushes it's level out of a normal range, which is beneficial to the body at the time.this is unlike negative feedback which reduces the stimuli.

During labour,the body releases the hormone oxytocin, which speeds up and increases contractions . this increase in contraction triggers an increase in oxytocin production until the child is born.

This is an example of positive feedback mechanism

Which molecule will undergo only london dispersion forces when interacting with other molecules of the same kind?.
chubhunter [2.5K]

Butane, C₄H₁₀ will undergo only London dispersion forces when interacting with other molecules of the same kind.

London dispersion force:

  • The weakest intermolecular force is called the London dispersion force.
  • When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the resulting transient attractive attraction is known as the London dispersion force.
  • There are instances when this force is referred to as an induced dipole-induced dipole attraction.

     Butane molecules only exhibit London dispersion forces because they are non-polar and have a symmetrical distribution of electron density.

<u><em>Butane:</em></u>

  • It is a covalent non-polar molecule. Every C-C and C-H bond is non-polar. This is because there is little or no electronegativity difference between C and C in C-C bonds and none between C and H in C-H bonds.

Describe the layers of the Sun.
Vikentia [17]
<h2>The layers of the Sun</h2>

There are three inner layers as the Core, Radiative Zone and Convection Zone. The external coatings are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will adjust its research on the Chromosphere and Transition Region. The above three are only the layers of the Sun.
