Explanation

 7t

First person distance traveled in time t = 28

 laps = 1

4 laps 

 Distance covered by the second person at time t = 38

 laps 

 First-person speed = 14t

 Second-person speed = 38t

 The two  start from A and B respectively, so they  meet  when there is a difference of 78

 laps. 

 Relative velocity of A and B: 

 = (38t-14t) = 18t

 Time  to complete 78

 laps at this speed: 

 = (78 × 8t) = 7t

Explanation

Simple squamous epithelium lines the alveoli, allowing for efficient gas exchange due to its thin, flat cells. 

Explanation

It is the total heat content of a system when the pressure is constant.

It helps us understand energy changes in chemical reactions.

Explanation

 When a stem is cut, water and nutrients may ooze out due to root pressure, a positive pressure in the xylem generated by water absorption in roots.

Explanation

The atomic mass of carbon is defined as 12.01 amu (atomic mass unit).

Since carbon exists as a single element, its molecular mass is also 12.01 amu. 

Explanation

Biology is classified as a natural science.

Because it studies living organisms and life processes through observation and experimentation.

Key Points:

Natural Sciences include:

1. Biology (study of life)
2. Physics (matter/energy)
3. Chemistry (substances/reactions)

Explanation

Green chemistry aims to:

1. Prevent waste creation
2. Maximize atom economy
3. Design safer, less hazardous chemicals and processes

These are all part of the 12 Principles of Green Chemistry outlined by Paul Anastas and John Warner.

Explanation

Bacillus bacteria:

These are rod-shaped, Gram-positive bacteria that can form endospores. 

Pseudomonas:

These are Gram-negative bacteria, not bacilli. 

Clostridium:

These are also Gram-positive bacteria, but they are anaerobic, unlike most Bacillus species. 

Salmonella:

These are Gram-negative bacteria, not bacilli. 

Streptococcus:

These are Gram-positive cocci (round bacteria), not bacilli. 

Explanation

Inner transition elements are the elements located in the f-block of the periodic table.

These elements are divided into two series: lanthanides and actinides

Therefore, both lanthanides and actinides are considered inner transition elements.
