Explanation

Active transport moves molecules against the concentration gradient, which requires energy (ATP).

Passive transport and facilitated (not vacillated) transport do not require energy.

Explanation

mRNA makes up only about 1–2% of the total DNA or genetic material content in a typical cell.

Most of the DNA is non-coding or used for other RNAs like tRNA and rRNA.

Explanation

The cell membrane is composed of roughly 40–50% lipids, primarily phospholipids and cholesterol.

These lipids form the bilayer structure, essential for membrane fluidity and barrier function.

Explanation

Humulin (human insulin) is produced using bacteria through recombinant DNA technology.

Explanation

The cerebellum is responsible for controlling balance, posture, and coordination.

Explanation

The theory that all living cells are of common origin is attributed to August Weismann. 

Explanation

Plants release more Carbon Dioxide (CO2) at night due to respiration.

Explanation

 Bronchial Asthma is a reversible inflammatory condition of the airways

Inflammation:

The primary characteristic of asthma is chronic inflammation within the airways, involving the lining of the bronchial tubes. 

Reversibility:

This inflammation and resulting airway obstruction can be reversed with medication, allowing airflow to improve. 

Triggers:

Asthma symptoms can be triggered by various factors like allergens, exercise, cold air, or viral infections. 

Symptoms:

Common symptoms include wheezing, coughing, chest tightness, and shortness of breath. 

Explanation

Gram-positive bacteria, such as Bacillus and Clostridium, are known for producing endospores.

Explanation

Blood, since family ties are fundamentally based on blood relationships.
