Answer: Affiliative behavior
Explanation:
Affiliative behavior is the behavior in which social interaction is seen between two animals through cohesion, meeting, hugging, involvement with each other, playful acts etc. They try to display emotional and social bond between them.
According to the question, chimpanzees displaying embracing behavior , ticking and little wresting shows that they have social and emotional link with each other.
Thus, they have affiliative behavior rather than aggressive and anger-based behavior.

• When the cue ball contact the other ball, momentum is transferred causing then to gain momentum and speed
• Less than 3m/s
Explanation
According to the law of momentum conservation, when two objects in an isolated system collide, the total momentum of the two objects before and after collision is equal .Momentum is directly proportional to both the mass of the objects and velocity. In this collision, the objects interact with each other thus they stick together after collision and move with a similar velocity. I.e. an elastic collision.

Answer:
Endospores Staining
Endospores are substances that are formed inside of specific bacterial cells which boost their survival rate in times of harsh conditions.
Gram staining alone is not sufficient to observe the endospores, which seems apparently clear when Gram-stained cells are observed.
Endospore staining employs two stains to identify endospores from other cell components.
•The Schaeffer-Fulton method employs heat to promote the primary stain (malachite green) into the endospore. Rinsing with water will well wash away the colour from the cell, as the endospore still appears to be green stained. Counterstaining pink with safranin will show the shape and location of endospores, if they are a part of the cell. The green endospores will be seen inside the pink vegetative cells or it will appear distinct from the pink cells in total. If no endospores are seen, only the pink vegetative cells will be observable.
The attached image shows a stained preparation of Bacillus subtilis revealing the endospores as green and its vegetative cells in pink coloration.
Endospore-staining procedures are essential for observing Bacillus and Clostridium, two genera of endospore-forming bacteria, production of bioterrorism agent from B. anthracis (which causes anthrax.
Answer:
1600cm³
Explanation:
The volume of a cuboid can be calculated as follows;
V = L × B × H
Where;
L = length (cm)
B = breadth or width (cm)
H = height (cm)
However, in this question, the area of the book is said to be 400cm². Since area of a rectangle or rectangular-shaped object like the book is L × B, this means that the length and breadth has been combined in the area. Hence;
Volume of the book = area of the book (L × B) × Height of the book (H)
Volume = 400cm² × 4cm
Volume = 1600cm³
Therefore, the volume of the book is 1600cm³.
