Let's solve both questions step by step.

Question 3: Complete the asexual reproduction in amoeba by drawing the figure.
Explanation:
Amoeba reproduces asexually through
binary fission, which is a process where the nucleus divides first (mitosis), followed by the division of the cytoplasm, resulting in two identical daughter cells.
The sequence of events in binary fission in amoeba:
1.
Parent cell (amoeba) with one nucleus.
2. The
nucleus divides into two nuclei (karyokinesis).
3. The
cytoplasm divides (cytokinesis), forming two separate cells.
4. Two
daughter amoebae are formed.
So, we need to complete the diagram:
- Box 2: Should show the
amoeba with divided nucleus (two nuclei inside the same cell).
- Box 3: Should show the
two separate amoebae, each with one nucleus.
####
✔ Completed Diagram (Description):
```
Step 1: One amoeba with one nucleus
→
Step 2: Same shape, but nucleus splits into two (still one cell)
↓
Step 3: Cell pinches in the middle, dividing into two parts (cytokinesis)
←
Step 4: Two separate amoebae, each with one nucleus
```

Drawing Instructions:
>
> - In
Box 2: Draw the same amoeba shape as in Step 1, but draw
two nuclei inside it.
> - In
Box 3: Draw the amoeba starting to split into two, with
one nucleus in each half, and the cytoplasm separating.

Question 4: Label the following figure and also identify the figure.
Observation:
The figure shows a
pair of ovoid structures connected to a central Y-shaped structure, with tubes leading from the ovaries to a central cavity. This is the
female reproductive system in humans.
#### 🔍 Identify the Figure:
➡️
Human Female Reproductive System
####
✔ Labels (from top to bottom, left to right):
1.
Ovary – small oval structure on each side; produces eggs (ova) and hormones.
2.
Fallopian Tube (Uterine Tube) – tube connecting ovary to uterus; site of fertilization.
3.
Uterus – pear-shaped organ; where embryo develops.
4.
Cervix – narrow neck of the uterus; connects to vagina.
5.
Vagina – muscular canal leading to outside.
> But since the diagram has
arrows pointing to three parts and one blank line below, here’s how to label:
Assuming the arrows point to:
-
Top arrow: Ovary
-
Middle arrow: Fallopian Tube
-
Bottom arrow: Uterus
And the
line below is for naming the whole figure.
####
✔ Final Answer:
Labels:
- Arrow 1 (top):
Ovary
- Arrow 2 (middle):
Fallopian Tube
- Arrow 3 (bottom):
Uterus
Figure Name: Female Reproductive System

✔ Summary:
Q3 Answer:
- Box 2: Amoeba with
two nuclei (after nuclear division)
- Box 3: Two
separate amoebae, each with one nucleus (after cytokinesis)
Q4 Answer:
- Labels:
- Top:
Ovary
- Middle:
Fallopian Tube
- Bottom:
Uterus
- Figure:
Human Female Reproductive System
