Answer:
Hemoglobin is an iron-containing protein present in the blood that functions for transportation of oxygen to different body cells..
Each hemoglobin molecule have tetrahedral structure consist of four heme groups surrounded by a globin group. Heme, is composed of porphyrin (ringlike organic structure) which is attched to an iron atom. There are four iron atoms in each molecule of hemoglobin that binds with four oxygen atoms and globin carry two linked pair of polypeptide chain.
The oxygen reversibly binds with the polypeptide chain and the process called oxygenation.
The offspring gets half of the required chromosomes from each parent. Human parents would give 23 chromosomes to their child as 23 + 23 = 46 chromosomes.
Bacteria move using a tail like structure called flagellum .
Answer:
1.) spindle fibers and centrioles form
2.) chromosomes align on metaphase plate
3.) chromosomes move to opposite poles
4.) two identical nucleotides form
Mitosis is important because it is responsible for the growth of is responsible for human development.
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation:
They’ve helped end/calm down pandemics and epidemics and allowed us to go out and start living our life again.
You don’t have to use this word for word just an idea
