Explanation:
An extinct species of australopithecine, that is, Australopithecus africanus was the first species to be illustrated. It was of gracile or slender build and was considered to have been the direct ancestor of modern humans. Like modern man, the A. africanus did stood upright and walked upright, and were having free hands to use. However, they were smaller in height and lighter in weight in comparison to modern man.
 
        
             
        
        
        
Answer is: <span>a. True.
</span>The overall effect of insulin is to lower blood glucose and amino acid levels by promoting their cellular uptake and incorporation into glycogen and proteins, respectively.  <span>The net effect of insulin is to decrease blood glucose and amino acids and stimulate the cellular uptake of these molecules and their incorporation into polymers.

Some of the key terms in community ecology are Intraspecific Interaction, interspecific interaction, competitive exclusion, mutualism.
<h3>
What is community ecology?</h3>
- Community ecology aims to provide solutions to these and other community-related concerns.
- An ecological community is a collection of organisms that coexist or may coexist in a given area. Communities are connected by a shared environment and a web of relationships between the many species.
- An ever-expanding and comprehensive area of ecology is community ecology. Ecologists look at the variables that affect species distribution, community structure, and biodiversity. Interactions with the abiotic environment and the wide variety of interactions that take place between species are two examples of these elements.
- The foundation of the majority of community ecology study is species interactions, such as competition, predation, herbivory, parasitism, and mutualism.
