A cell's ratio of surface area to volume will limit:

most cells are very small, because ____

"As organisms develop, their cells differentiate into specialized cells."

In this sentence, differentiate means:

Which of these is NOT a characteristic of asexual reproduction?

Select the one that is a form of asexual reproduction

Which of these is NOT a characteristic of sexual reproduction?

series of events in which a cell grows, prepares for division, and divides to form two daughter cells

structure found in animal cells that helps reel in spindle fibers to move and separate sister chromatids

the cell grows (G1), replicates DNA (S), and prepares for division (G2)

On average, cells spend _____% of their cell cycle in interphase.

DNA Replication occurs during ____ Phase of Interphase

threadlike structure of DNA and protein that contains genetic information; in eukaryotes, these are found in the nucleus; in prokaryotes, these are found in the cytoplasm

one of two identical copies of a duplicated chromosome

area where two sister chromatids are held together (until separated during anaphase of mitosis or anaphase II of meiosis)

this occurs when cells grow and divide uncontrollably (the cell cycle is out of control)

division of the nucleus

spindle fibers form, genetic material condenses and chromosomes become visible, nuclear membrane breaks down

chromosomes line up across the center of the cell

centrioles reel in the spindle fibers to separate centromere holding sister chromatids together

chromosomes are moved to opposite side of the cell, the nuclear membrane reforms around chromosomes

daughter cells' cytoplasm divides, two identical cells are forms

Which of these is not a result of mitosis?

cellular division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell

a cell with two full sets of chromosomes

a cell with one set of chromosomes

chromosomes that contain the same genes, but not necessarily the same versions of those genes (you received one of these from each parent)

homologous chromosomes find each other and pair up during Meiosis I (Prophase I) to form a _____.

The first phase of Meiosis I where homologous chromosomes pair up and form a tetrad, crossing over can occur

The second phase of Meiosis I where tetrads line up along the center of the cell

The third phase of Meiosis I where spindle fibers move homologous chromosomes to opposite sides of the cell (tetrads are separated)

The fourth phase of Meiosis I where sister chromatids uncoil, the nuclear membrane briefly reforms, and two cells are formed

The first phase of Meiosis II where sister chromatids condense and the nuclear membrane breaks down

The second phase of Meiosis II where sister chromatids line up along the center of the cell, but not in tetrads

The third phase of Meiosis II where sister chromatids are separated from each other

The fourth phase of Meiosis II where the chromosomes uncoil, nuclear membrane reforms, and four haploid cells are formed

At the end of meiosis in females, _____ egg cell(s) is/are produced.

At the end of meiosis in males, _____ sperm cell(s) is/are produced.

Which of these is not a result of meiosis?
