The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle. What is a result of preventing spindle fibers from forming? Answer
A The cell cycle skips G1 phase
B Mitotic division is skipped, and the cell cycle proceeds to cytokinesis.
C Mitotic division stops in metaphase and cannot proceed to anaphase.
D The cell cycle skips S phase and proceeds to G2 phase.
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.

What would happen to the geosphere if there was no hydrosphere? Think of weathering and erosion
Answer:
Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of air temperature between the land and oceans). This rock cutting shows the rocks that have formed on the surface of the Earth. Last of all, without the geosphere, there would be no world to live on!

Which graphic organizer best represents asexual reproduction? Which graphic organizer best represents sexual reproduction? Explain your answers.
The one with one parent and five offspring represents asexual reproduction. Asexual reproduction only requires one parent, so the offspring are genetically identical to the parent. The advantage is that organisms can reproduce much quicker using this method.
The organizer with two parents and one offspring represents sexual reproduction. Again, sexual reproduction requires two parents.

Answer:
1. Plate boundaries are the edges where two of the Earth's plates meet
2. The three types of plate interacts include divergent boundaries, convergent boundaries, and transform boundaries.
3. This is the theory that the Earth's crust is separated into plates that move over the Earth's mantle. As stated, they can move in ways such as coming together, spreading apart, and interacting at boundaries all over the planet, which can cause things such as volcanos and earthquakes. Scientists created this theory as a way to explain why certain events like these are caused.

What can a person do to prevent barriers to exercise? Select three options.
Answer:
Explanation:
Three things that anyone can do to prevent this would be
understand myths about working out
look for inexpensive classes in the area
take a physical education course at school
Most barriers to exercise revolve around becoming discouraged/depressed about the results due to having unrealistic and high expectations. Learning about what you can expect realistically from a set routine will greatly increase motivation and prevent such barriers. The same applies to learning which routines and diets work best and all of this can be learned by taking physical education courses or classes near you.
Answer:
understand myths about working out
look for inexpensive classes in the area
