Answer:
See explanation
Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.

What do surface current affect !!!!
Answer:
Surface currents affect climate by moving cold and warm water around the globe. In general, currents carry warm water from the tropics toward the poles and bring cold water back toward the equator. A surface current warms or cools the air above it, influencing the climate of the land near the coast.

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.

Select ALL the correct descriptions that help to define luminosity.
A. How much energy is emitted per second
B. How much surface area the object has
C. The amount of brightness of an object
D. The color emitted by the start
The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.
What is the energy content of luminosity?An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.
What factors affect luminosity?A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
What three things have an impact on luminosity?The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

How does a visking tubing differ from a cell membrane
Join the following terms:
Answer:
The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.

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.

True or false. Without wind there would be no weather.
Answer: Absent a gentle breeze or mighty gale to circulate both warm and cold weather around the Earth, the planet would become a land of extremes. Areas around the Equator would become intensely hot and the poles would freeze solid. Whole ecosystems would change, and some would completely disappear.
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!
