The main difference between the nebular and condensation theories is that the condensation theory stresses the importance of interstellar dust to the formation of planets.
Interstellar dust is a significant component of the galaxy. It is produced in many various locations in the universe such as in the cooler outer layers of red giant stars where it is eventually blown off by the solar winds and it can also be produced in the expanding shell of gas residue from a supernova remnant. The central part of the interstellar dust is enclosed by ice and it is made up of either silicates or metals or at times a little of both.

Answer: Canyon
A canyon is a deep, narrow valley that exhibits steep sides. The canyon is usually formed on the mountains or plateaus as V shaped valley, when the rocks are weathered by the water of river and erosion by high speed wind current.
Therefore, on the basis of above information Canyon is a feature which is most likely to be formed by flowing water.

The diagram shows a Circuit as a result of the combination of cells
present in it.
This is referred to a path in which electric current flows through. It is
divided into the following which include:
The diagram above depicts a closed circuit as there is no breakage in the
flow of current.

The male human has a sperm cell and the female has an egg cell. The cells from the male and female that combine to form a zygote are called gametes. The human sperm and egg cells each contain 23 chromosomes. . A combination of gametes forms a zygote with 46 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.
The gametes B and C are the ones that contain one or more recombinant chromosomes, option 4 is correct.
Recombinant chromosomes are formed through the process of genetic recombination, where genetic material is exchanged between homologous chromosomes during meiosis. The exchange of genetic material results in new combinations of alleles on the chromosomes.
The B and C gametes are likely to contain recombinant chromosomes because they are a result of the crossing over and recombination that occurs during meiosis. Gamete B is likely to have undergone genetic recombination, as it carries a combination of alleles from both homologous chromosomes. Similarly, gamete C is also likely to contain recombinant chromosomes due to the recombination process.
The other options may not necessarily contain recombinant chromosomes, as they may have inherited intact, non-recombined chromosomes from the parent cells during meiosis, option A is correct.
