So white blood cell’s(WBCs for short) main job is to fight infections.
They do this by swallowing the infection.
You see,WBCs do not have a permanent shape.this means that they enlarge and decrease size of parts of their body.So they grow two long arm like structures called pseudopodia which swallow the infection.(pseudopodia means false feet).
You can see the process in the photo I attached from google
It’s symmetrical if it’s equal on both sides?
Answer:
The correct answer will be- formation of membrane
Explanation:
The three-stage origin of life theory suggests that life on Earth originated in three phases which are:
1. Phase I: The larger molecules formation began during this unsuitable earthly conditions full of volcanic eruptions and harmful gases underwater.
2. Phase II: The self-replicating molecule begins to form during this phase which contained the coding of life. The self-replicating molecule is known as the formation of the membrane.
3.Phase III: The formation of the membrane which help separate the outer environment from the inner environment was observed during this phase.
Thus, the formation of a membrane is the correct answer.
