what is found in the molecule dna?

Answer:

A: petal

B:stigma

c: stamen

Explanation:

A flower is considered as a complete one if it has petals, stamen, carpel and sepals. Sometimes pistil is present. Here in the structure part A is Petal, B is Stigma and C is stamen.

The calyx, corolla, androecium, and gynoecium are found to be the four whorls of a modified leaves which constitute the flower. One of the flower parts in each of the whorl contains sepals, petals, stamens and pistils.

Here A is petal. This part is the bright coloured region which attracts bees and birds. This part help us to differentiate one flower from another. Some petals are dark coloured whereas some other are pale coloured.

Here B is stigma. The stigma is the sticky part of a flower. It is the specially adapted portion of the pistil modified for the reception of pollen. It has a feathery, branched elongated structure.

Here C is stamen - The male reproductive part of a flower is called the stamen. The stamen has long slender stalk called the filament with a two -lobed anther at the tip.

Thus the given parts are petal, stigma and stamen.

The melanin provides protection against skin cancer by absorbing harmful UV light from the electromagnetic spectrum.

The electromagnetic spectrum consists of radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Answer:

When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.

So I think its C

You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

Hope This Helps :)
