The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum primum and the septum secundum that partially overlap.
What is septum primum and septum secundum?
- The septum primum, which divides the right from the left, is a structure inside the primitive atrium.
- In the direction of the endocardial cushions, this septum descends.
- The foramen primum, a hole in this septum, keeps the blood flowing through the heart.
- The foramen secundum develops as the foramen primum shrinks in size.
What is the purpose of septum secundum?
- A muscular flap called the septum secundum plays a significant role in heart growth.
- It has a semi-lunar form and develops from the atrium's upper wall to the right of the septum primum and ostium secundum.
- It is crucial for the foramen ovale to close after birth.

<u>The correct question is -</u>
The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum ______ and the septum ______ that partially overlap.
Answer:
A-B-C-D
Explanation:
PROPHASE; 1. chromosomes become thicker
2. nuclear membrane disintegrates
3. centrosome divide to form centrioles
4. centrioles move to the opposite polls of the cell
METAPHASE; 1. chromosomes get arranged at the equator
2. centrioles produce spindle fibre that attach to the middle of the chromosomes
ANAPHASE; 1. shortest stage of mitosis
2. spindles will pull apart each chromosomes to form chromatids
TELLOPHASE; 1. each chromatid moves to opposite polls of the cell
2. nuclear membrane appears around both of them
3. the centrioles sill stop producing spindles
4. centrosomes will then form again
cytokinesis then divides by the cleavage furrow to form the two daughter cells
Given:
The solution decreased by 
ounces every hour for 5 hours.
Remaining solution at the end of the experiment = 
ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by ounces every hour for 5 hours.
Total decreased amount 
Initial amount = Remining amount + Decreased amount of solution.
Therefore, the initial amount of solution is 18 ounces.
Because the energy is going to decrease to also nothing and the animals at the top have to hunt more than those closer to the bottom of the food web
