Answer: Option A
Explanation:
The T-cells and B-cells of the immune system are the part of specific immune response.
If the number of T-cells dies then the ability to activate B lymphocytes will also be lost as they help B-cells to secrete antibodies and macrophages to destroy the antigens.
T cells also helps in the activation of cytotoxic T-cells to kill the targeted cell which is affected by antigens.
hence, the correct answer is option A
The gasping respiration, and positive pressure ventilation via face cover should be started with 21 percent oxygen or blended oxygen using a self-inflating bag, flow-inflating bag.
<h3>What should you do if the neonate's heart rate falls below 60 beats per minute?</h3>
If the heart rate drops 60 bpm despite good oxygenation and ventilation, start chest contractions.
If the heart stays drops 60 bpm after 30-45 seconds of cogent chest squeezes, epinephrine 10 mcg/kg should be nursed intravenously.
Thus, positive pressure ventilation via face cover should be initiated with 21 percent oxygen.

The steps to a lab experiment in the correct order are as follows:
- A statement of the experimental question or purpose.
- A hypothesis of the most likely results.
- Detailed sequential procedural steps for performing the experiment, and a list of needed materials.
- Data was collected from the experiment and organized for analysis with charts, graphs, and diagrams.
- A conclusion of the analysis and an explanation of the trends.
<h3>What is a Lab experiment?</h3>
A lab experiment may be characterized as an investigation strategy by which researchers assemble controllable environments to test some hypotheses to reveal some conclusions.
Therefore, the correct order of a lab experiment is arranged above with sequential steps.
