There are no choices but the reason why we tend to value
friends as we grow older is because these are bonds that we create on our
own. These are people who have been
there for us throughout our lives. They are our link with the outside world
since they are not our family members.
The longer we are friends with others, the deeper that bond becomes.
Typically blue is to represent A-adenine, yellow is T-thymine, green is G-guanine, and red is C-cytosine.
They communicate with smells, sounds, visual messages, and touching.
<h3>Vocal Communication in Primates:</h3>
Animals frequently communicate through voice. In order to trace the evolutionary roots of our sophisticated communication system, researchers frequently study vocal communication in nonhuman primates (primates) with the goal of detecting similarities and differences between human language and speech. Listeners appear to comprehend the meaning of the sounds made by primates in response to particular occurrences, such as the discovery of a particular predator. Although this form of communication and human referential words appear to be similar on the surface, the mental processes that underpin them may be extremely different.
There is far more disagreement regarding whether the production of ape vocalizations and language share any similarities, despite the fact that generally speaking, the flexibility displayed by primate receivers may exhibit some similarities with humans. It is generally acknowledged that primates, unlike humans, cannot produce novel vocalizations.

Answer:
The current answer is b) bacteria need for proper growth and cannot make themselves.
Explanation:
An essential nutrient is one which is required to the cell for the proper growth from the environment because it cannot be synthesized by the cell itself.
Some essential nutrients that bacteria require for their growth are carbon, nitrogen, water, iron, inorganic salts, and many other molecules.
These nutrients should be given from an easily available source to the bacteria for their proper growth because these nutrients are required to perform essential metabolic activities and can not be synthesized by bacteria on their own.
