Question

Which type of cell lacks a nucleus and carries oxygen through blood using hemoglobin

A. thrombocytes
B.leukocytes
C.plasma
D.erythrocytes

Answer 1

Red blood cells (erythrocytes) lack a nucleus and carry oxygen through the blood using hemoglobin.

Step-by-step explanation:

Red blood cells (erythrocytes) lack a nucleus and carry oxygen through the blood using hemoglobin. Hemoglobin is a protein that binds to oxygen and transports it throughout the body. White blood cells (leukocytes), on the other hand, are primarily involved in the immune response and do not carry oxygen or have a nucleus. Therefore, the correct answer is Option D: erythrocytes.

Answer 2

D.

Step-by-step explanation:

The type of cell that lacks a nucleus and carries oxygen through blood using hemoglobin is option D, erythrocytes. Erythrocytes, also known as red blood cells, are the most abundant type of blood cell and are responsible for transporting oxygen from the lungs to the body's tissues. Their unique shape and lack of a nucleus allow them to efficiently carry oxygen and navigate through narrow capillaries. The hemoglobin protein inside erythrocytes binds to oxygen and carries it throughout the body.
