Answer: the correct answer is C
Explanation:
Preventing the formation of spindle fibers makes the mitotic division stop in metaphase, and thus fail to proceed to anaphase.
• Colchicine prevents the polymerization of the microtubule, and thus, prevents the arrangement of the mitotic spindle, which shows the prevalence of another checkpoint in the cell cycle.
• As a result, the activity of the maturation promoting factor remains high, the chromosomes stay condensed, and the nuclear envelope fails to redevelop.
• A toxic effect is exerted on the living cells by the colchicine, which usually results in the arrest of the process of mitosis at an eventual stage, generally the metaphase, with the generation of unusual and bizarre nuclear configurations, and thus, resulting in the death of the cell.
Thus, the correct answer is option C.

Your friend makes a claim that the image to the right shows facilitated
diffusion. You are an educated Honors Biology student, and you believe
that he/she is incorrect in their claim. Make a claim as to which type of
cellular transport is represented in the image (1 point)State TWO pieces of
evidence from the image that supports your claim (2 points).*
Answer:
Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.
Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

Genetic variation is inherited by offspring.
A. Artificial aelection
B. Natural Selection
C. Both
Answer:
Both
Explanation:
A person's skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population. Examples of genetic variation in plants include the modified leaves of carnivorous plants and the development of flowers that resemble insects to lure plant pollinators. Even though in artificial selection, you take which genes are desired it is still passing genetic variation through offspring.
Diffusion is the movement _____.
of molecules to an area of lower concentration
of molecules through the cytoplasm of a cell
of water through a selectively permeable membrane
of molecules to an area of higher concentration
Answer:
of molecules to an area of lower concentration
Which two phases do the chromosomes exist as chromatin (unraveled form of chromosomes)?
Answer:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
Explanation:
Answer:
Prophase is the first step of mitosis. This is when the genetic fibers within the cell’s nucleus, known as chromatin, begin to condense and become tightly compacted together. During interphase, the parent cell’s chromosomes are replicated, but they aren’t yet visible.

Explain what happens to a cell as it enters the cell cycle and goes through the process of
MITOSIS. Tell what happens to the cell at each part of the cell cycle starting at
Interphase, then the stages of Mitosis (PMAT) and ending at Cytokinesis. (This should be
a longer response than one sentence!!)
Answer:
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
