Answer:
Cells divide twice
Explanation:
Meiosis may be defined as the process of cell division in which a single cell divides to give four daughter cells and each daughter cells have half number of chromosomes.
Meiosis is also known as reduction division as the chromosome number reduces upto half in the progeny cells as compared with the parent cell. The cells divide twice in meiosis and give rise to four daughter cells.
Thus, the correct answer is option (4).
A) Vibrations
Sounds vibrate the eardrum
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.
