Answer:
The correct answer is: Meiosis makes it possible for a zygote to have the correct number of chromosomes.
Explanation:
Meiosis is a type of cell division used by reproducing organisms to produce the gametes (as sperm or egg cells). It has two rounds of division that results in four cells with one copy of each chromosome.
Before the division, genetic material from each chromosome is crossed over and creates new combinations of code on each chromosome. During fertilization, the cells produced by meiosis will conjoin to create a cell with copies of each chromosome again, the zygote.
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.
