These anatomical structures are the following:
1. The urine itself which serves as an antiseptic, washing potentially harmful bacteria out from the body during normal urination
2. The ureters join into the bladder in a manner designed to prevent urine from backing up into the kidney when the bladder squeezes urine out through the urethra.
3. The prostate gland in men that secretes infection-fighting substance.
4. The immune system defenses and antibacterial substance in the mucous lining of the bladder eliminate many organisms.
5. The vagina of a healthy women, it is colonized by lactobacilli, a beneficial microorganisms that maintain a highly acidic environment (low pH) that is hostile to other bacteria. It also produces hydrogen peroxide, which help eliminate bacteria and reduces the ability of Escherichia coli (E. coli) to adhere to vaginal cells that is the major bacterial culprit in urinary tract infection.

Answer:
<h2>Its true!!</h2>
Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!
Answer:
The given statement is true.
Explanation:
A condition in which uncharacteristically large, unusual and immature RBCs known as megaloblasts gets generated by the bone marrow is known as megaloblastic anemia. The condition can arise due to many causes of which deficiencies of folate or vitamin B12 (cobalamin) are the most general ones. The mentioned vitamins perform an essential function in the generation of RBCs.
The signs and symptoms of megaloblastic anemia are lightheadedness, shortness of breath, pale skin, unusual heartbeat, and dizziness. Some of the other signs of the condition are weakness in muscles, pains and aches, and dyspnea.
By low temperature, it can melt. High pressure will raise the melting point of the rock.
