To answer this question, subtract from the total population of 1000 the homozygous dominant (DD) frogs of 280 and the homozygous recessive (dd) frogs of 220, and you are left with 500 frogs that by default are <span>heterozygotes (dD). The frequency of these frogs would be 500/1000 = 0.5</span>
Except Erythrocytes, <u>because insects do not have the Red Blood Cells</u>.
Erythrocytes- Red blood cells, also known as erythrocytes or RBCs, are biconcave, anucleate cells that contain <u>hemoglobin </u>and carry oxygen and carbon dioxide between the lungs and organs. Erythropoiesis, a process in the red bone marrow, is what creates them.
Hemoglobin- The protein molecule known as hemoglobin is found in red blood cells and is responsible for transporting oxygen from the lungs to the body's <u>tissues </u>and carbon dioxide from the tissues back to the lungs. Four linked protein molecules (globulin chains) make up the hemoglobin molecule.
A collection of cells with similar structures and functions is referred to as a tissue.
