Answer:
The biologist is studying about the ecological community.
Explanation:
The ecological community refers to the community in which population of different types of species survives together. As the biologist is observing about the interaction of different populations of Pennsylvania region, it can be inferred that the he is studying about the ecological community of Pennsylvania region.
The population surving in the community interact with each other through different modes of interaction. It may either parasitic, or mutual, or competitive or predication or commercialism.
It is very true that masculinity and femininity are very strongly dependent on the society in which these terms are used. While there are genetic differences underlying the phenotype of being more masculine (having a bigger jaw, more hair on the body), there are also a lot of societal factors determining what is considered to be masculine and what feminine in a society.
Answer:
four haploid cells.
Explanation:
meiosis is a reduction division where the contents are equally divided in two cells and so the genetic material becomes half.
during mitosis he genetic material doubles first and then the cell divides
but for meiosis the cell divides first and the genetic material replicates later in the second phase of cell division,because two divisions take place in one cycle the result is four cells.
This is called the myelin sheath.
Answer:
Discover the volume of a balloon.
Explanation:
Get a balloon and a piece of paper. Cut the paper to make a line, and make sure it is 100 cm x 2 cm Take on of the balloons and inflate it several times so you are sure you can inflate the balloon with only one breath. Take a deep breath and inflate the balloon. Use a binder clip to hold the neck so no air escapes. Make a measurement of the circumference of the balloon using v = c3/6(pie)2 - the formula is c cubed divided by 6 times pie squared equals volume. Create a graph for them to answer, and then give questions for them to turn in.
