You observe two populations of chimpanzees using sticks to dig termites out from nests for food. One population uses long sticks
icang [17]

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.

What kind of bond is broken and reform to release energy from food molecules
Andreas93 [3]

Answer:

    Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products.

Explanation:

Hope this helps!

Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. ... Breaking chemical bonds absorb energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
