Answer: B. The population using long sticks has mostly long sticks in its environment
Explanation:
Going back to the statement that reiterates the hypothesis after observations about the apes in the Introduction. 
Reviewing the findings in this case, on the behavior of using sticks to dig seem to be the focus the experiment and choice length of the stick.
Making a judgment about whether or not the two finding has been supported is next step.
If there are equal numbers of short and long sticks in the environment of each population and the apes chooses one specific we can say their behavior is learned.
 If the chimpanzees using short sticks have made the the sticks short by breaking long sticks then we can say this behavior is learned.
When the Young chimpanzees in both populations start out using sticks of many different sizes we can see that these variables of learning is yet to be perfected.
When individuals in the population that don’t use the common stick length for that population catch fewer termites this reveals a randomness in the behavior of interest.
At this point we can say that if the population using long sticks has mostly long sticks in its environment then there is a biased objective in the study and this does not support the hypothesis that the choice of stick length is a learned behavior.
 
        
             
        
        
        
The slow gradual change is called proposed.
it process organisms w/ favoable traits to survive hope this help meh friend :)
        
             
        
        
        
Answer:
 3) away from the area where it is more  concentrated
Explanation:
A substance that moves across a cell membrane  without using the cell's energy tends to move away from the area where it is more  concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
All other options are incorrect because,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
 
        
             
        
        
        
Answer:
Yes 
Explanation:
An energy pyramid shows the amount of  available at each feeding level in an ecosystem. This energy pyramid shows the amount of energy available at each tropic level showing the food energy progression. The pyramids contain energy starting with the producers (plants) at the bottom to primary consumers, tertiary consumers and so on up to the top of the food chain. The most common units are grams per square meter per year or calories per square meter per year.
