According to the image, X is for attracting pollinators, Y is for the production of pollen, and Z is for the production of eggs

<h3>Parts and functions of flowers</h3>

The image shows the different parts of a typical flower.

X is a petal. Petals are usually colorful and serve to attract insect pollinators to flowers.

Y consists of the anther and the stigma. Both represent the male organ of the flower and produce the male gametes, otherwise known as pollens.

Z consists of the stigma, the style, and the ovary. They all represent the female reproductive organ of the flower. Pollen lands on the stigma, travels through the style, and reaches the ovary. The ovary houses the ovule or the eggs.

a drop of sara’s blood was mixed with anti-a serum. another drop was mixed with anti-b serum. and a third drop was mixed with an

Natali [406]

The blood group from the observation is O negative.

The blood groups can be determined practically with the help of anti-serums.

One of the groups into which people or their blood can be classified based on the presence or absence of particular antigens in the blood (such as those labelled A, B, AB, or O) is called as blood group.

There are 4 main blood groups (types of blood) – A, B, AB and O.

Red blood cells, white blood cells, and platelets are contained in a fluid called plasma, which is the blood. Antibodies and antigens found in the blood help identify your blood group.

Plasma contains proteins called antibodies. They are a component of your body's built-in defenses. They identify alien objects, like bacteria, and notify your immune system, which then eliminates them.

Protein molecules called antigens can be detected on the outer layer of red blood cells.

The ABO system distinguishes 4 major blood types:

Red blood cells with blood group A antigens have anti-B antibodies in their plasma.
B antigens and anti-A antibodies are present in the plasma in blood group B.
Blood group O - has both anti-A and anti-B antibodies in the plasma but no antigens.
A and B antigens are present in blood group AB, however there are no antibodies.

So, as the question tells that Sara's blood doesn't coagulate with anti serum a, b and rh this means that her RBCs have none of the proteins on its surface leading to Blood group O negative.
