Answer: controls milk production release

Explanation:

Oxytocin is a cyclic peptide containing 9 amino acid residues. In its molecule, we find several amide groups (-CONH), which were formed through peptide bonds between amino acids. It is produced in the paraventricular nuclei of the hypothalamus by the magnocellular neurons but is released only in the neurohypophysis. Oxytocin is a fundamental importance in birth labor and the ejection of milk. Oxytocin acts on labor by stimulating uterine contractions, as well as dilating the vaginal canal and distancing the pubic symphysis. The suction promoted by the babies in the halo of the mother's breast also promotes the release of oxytocin, whose function is to help in the secretion of milk.

What 3 things are necessary for germination to begin
Jlenok [28]

Answer:

water, correct temperature, and a good location.

Explanation:

Seeds wait to germinate until three needs are met: water, correct temperature, and a good location. During its early stages of growth, the seedling relies upon the food supplies stored with it in the seed until it is large enough for its own leaves to begin making food through photosynthesis.

If you place a strong acid in water it will likely ionize. If you put the same acid in oil it will not. Why the difference?
denpristay [2]

Answer

An acid that breaks down completely and gives off many ions, or protons, is considered to be a strong acid. ex H₂SO₄

If you place strong acid into water it dissociate acid into H⁺ ions

Water is polar solvent(H⁺ and OH⁻), which has partial positive charge on one side and partial negative charge on the other side.

Strong acids readily dissociate in polar solvents to give H+ ions.

Where as Oil is a non polar solvent it has same charge all over so no dissociation of strong acid will take place.

A record turntable is rotating at 33 rev/min. A watermelon seed is on the turntable 7.8 cm from the axis of rotation. (a) Calcul
Novosadov [1.4K]

Given data:

● Angular velocity of the turntable ω = 33 rev/min

Therefore,

ω = 33 rev/min

ω = 33rev/min × 2π rad/rev × 1 min/60 sec = 3.45 rad/s

● The distance of the watermelon seed from the axis of rotation r = 7.8 cm = 0.078 m

● μs = the coefficient of static friction

Section a:

The seed is undergoes circular motion and it is been effected by centripetal acceleration.

ac = rω^2

ac = 0.078 × 3.45^2

ac = 0.9284 m/s^2

Therefore,

the centripetal acceleration of the seed is 9.274 m/s^2

Section b:

If the seed is observed not to slip at the course of the circular motion, then the supplied frictional force given by the seed and surface of turntable would at least be equivalent to the centripetal force working on the seed.

Centripetal Force = Frictional Force

mrω^2 = μsmg

μs = rω^2 /g

μs = 0.078 × 3.45^2

------------

9.81

μs = 0.09464

Thus,

the coefficient of static friction is 0.09464.
