The graph below shows a change in beak depth (beak size) of the medium ground finch over a period of years. Based on the theory of natural selection, which of the explanations best describes the change in the beak depth of the medium ground finch during the dry years?

A.
The beak size of an individual finch decreased during dry years due to the survival and reproduction of finches with beak sizes greater than 9.6 mm.

B.
The beak size of the finch population increased during dry years due to the survival and reproduction of finches with beak sizes greater than 9.6 mm.

C.
The beak size of an individual finch increased during dry years due to the survival and reproduction of finches with beak sizes greater than 9.6 mm.

D.
The beak size of the finch population decreased during dry years due to the survival and reproduction of finches with beak sizes greater than 9.6 mm.

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells

If a cell is placed into a hypertonic environment,what will happen to it ? a)it will shrink or shrivel b)nothing c)it will burst d) it will expand or enlarge

The table above shows five different types of chromosomal abnormalities that can occur during meiosis. they result in either an individual having too many or too few chromosomes in their genome. what is the most likely cause of these chromosomal abnormalities?
