Which structure of a flower releases pollen?

anther
sepal
pistil
ovary

Anther

Explanation:

The anther is the structure within the flower that makes the pollen and later releases it. The sepal is the part of the flower that protects developing flowers; leaf-like. The pistil (aka carpel) consists of the stigma (pollen landing site), style (elevates stigma to aid in pollination; connects ovary), and ovary. The ovary is what surrounds the ovule/seed of the plant.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
