A biologist began studying a population of bullfrogs. In 1998, she found that
most of the male frogs croaked, but some did not. A bat species known to
prey on male frogs migrated to the area in 2005. The biologist returned to the
area in 2008 and repeated population counts of male frogs. The table shows
her data
1998
2002

noncroaking males

What factor most likely caused the noncroaking male population to increase
after 2004?
O
A. Extinction of the croakers because of the new predator
O
B. Adaptation of the croakers in the presence of a new predator
O
c. Learning to avoid the new predator
O
D. Selective pressure in the form of a new predator
HELP HELP PLEASE!!

C.The bats response to the croaking behavior of male frogs led to selective pressure against the croaking trait in frogs. Did that help?

Explanation:

the answer is "meiosis ii in the mother".

the procedure of meiosis includes two divisions of the hereditary material. the main division is known as the decrease division – or meiosis i – on the grounds that it lessens the quantity of chromosomes from 46 chromosomes or 2n to 23 chromosomes or (n depicts a solitary chromosome set). in people, the decrease division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one disposed of polar body. the second division – or meiosis ii – is called equational division. the two sperm cells split again creating four sperm cells, each with 23 or n chromosomes. in oogenesis, the egg cell and polar body partition to shape the ovum and two extra polar bodies. along these lines, the posterity are guaranteed to get one portion of the chromosomes from the mother and one half from the dad.
