5. If an organism has 5 pairs of chromosomes and no crossing over occurs, how many different
arrangements of chromosomes are possible in the gametic cells? Explain.
Answer:
In spite of the fact that he didn't have any acquaintance with it, Walther Flemming really noticed spermatozoa going through meiosis in 1882, yet he confused this cycle with mitosis. Regardless, Flemming saw that, dissimilar to during standard cell division, chromosomes happened two by two during spermatozoan improvement. This perception, continued in 1902 by Sutton's careful estimation of chromosomes in grasshopper sperm cell improvement, given conclusive insights that cell division in gametes was not simply customary mitosis. Sutton showed that the quantity of chromosomes was decreased in spermatozoan cell division, a cycle alluded to as reductive division. Because of this cycle, every gamete that Sutton noticed had one-a large portion of the hereditary data of the first cell.

Maria wanted to grow a fern in her backyard. Acting on a suggestion from a friend, she collected brown dots from the underside of a fern's leaves and then potted them. After a few days, Maria saw small fern leaves erupting from the pot. Which statement explains this phenomenon? A. The fern transitioned from gametophyte generation to sporophyte generation. B. The fern grew as a result of mitosis. C. The fern transitioned from sporophyte generation to gametophyte generation. D. The fern grew to be genetically identical to its parent plant.
Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.
Explanation:
Ferns undergo an ALTERNATION of GENERATIONS in their reproductive life cycle. That is, they alternate between an incospicuous gametophytic stage and a dominant sporophytic stage. The sporophyte produces haploid spores, which germinates into the gametophyte plant called PROTHALLUS.
The gametophyte produces gametes (male and female) which fuse together to form the diploid zygote, which eventually develops into the SPOROPHYTE plant via mitosis. In this question, the brown dots from the underside of a fern's leaves that Maria collected are the spores.
When she places them in a pot, the spores germinated into gametophyte stage, then formed sporophyte, which is the small leaves she noticed growing from the pot. From this, it can be observed that the fern is transitioning from GAMETOPHYTE generation to SPOROPHYTE generation.
Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.

Which air mass is associated with low relative humidity and high air temperature?
Answer: Continental tropical.
Over continents, continental air masses form. These air masses contain only modest amounts of humidity. Polar or tropical locations can both support the development of continental air masses.
What air mass is low relative humidity, high air temperature?A humid air mass that originates over water is the maritime air mass. Over land, air masses with a continental climate are created.
It is referred to as a continental polar air mass because of how cold and dry the air mass that forms over northern Canada is. An air mass that is warm and humid, known as a maritime tropical air mass, forms over the Indian Ocean.
The relative humidity of the air in the house decreases as cold air, which has less moisture than warm air, enters and is heated.
Therefore, Summer air conditioner use, which takes moisture from the air as it functions, can also contribute to low humidity in arid locations.

The image below shows the process of DNA replication. Identify the components of the process.
Sorry I'm late, God bless!
The given diagram shows DNA replication in mammals. The labelled parts of DNA replication in this diagram are: DNA Polymerase, RNA primase, topoisomerase, Okazaki fragments, and DNA helicase.
What is DNA replication?DNA is the genetic material in human beings. The double-stranded DNA undergoes replication to divide and form daughter strands. The main enzymes required for the replication are: DNA Polymerase, RNA primase, topoisomerase, Okazaki fragments, and DNA helicase.
DNA Polymerase: It is responsible for the polymerization of new strands of DNA
RNA primase: The polymerase requires a primase for the proper attachment on the DNA strand to begin the replication process
Topoisomerase: This class of enzyme is responsible for introducing negative supercoils in the strands of DNA which will open up the DNA double strands
Okazaki fragments: The okazaki fragments are present in the lagging strand of DNA. These are the small fragments of DNA which is not synthesized continuously
DNA helicase: These enzymes are responsible for the separation of the double strands of the DNA molecule.
