The <u>bladder </u>is in the hypogastric region. 
Hypogastric Region- The structures around the pelvic bone are located in the hypogastric area. These include the prostate in men and the womb and ovaries in women, as well as the bladder, a section of the colon and rectum, the anus, and several reproductive system organs.
Bladder- A little above and behind pubic bone in the pelvis, the urine bladder is a muscular sac. The bladder is roughly the size and shape of a pear when it is empty. The kidneys produce urine, which then passes via capillary called ureters and into the bladder. Urination can be restricted and rare because to the bladder's ability to hold pee.

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.
Answer: Option A
<u>Explanation:
</u>
Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.
Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.
 
        
             
        
        
        
Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome. 
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

Most bacteria are heterotrophic decomposers, which means they depend on other organisms for food and feed on dead matter.
