Explanation:
The first living organisms.
The right order for the fungi to reproduce sexually is:
<u>hyphae exchange genetic material, a spore forms, and the spore grows into a genetically unique fungus.</u>
<h3>What is fungus?</h3>
- Any member of the eukaryotic group of organisms, which also includes the more well-known mushrooms and microbes like yeast and mold, is referred to as a fungus.
- Some of the examples for Fungi are rusts, yeasts, molds, stinkhorns, truffles, mushrooms
<h3>Where can you find fungi?</h3>
- Fungi can be incredibly sophisticated multicellular organisms or single-celled critters.
- They can be found in almost any location, but the majority of them prefer to dwell on land, primarily in soil or on plant matter, as opposed to the sea or fresh water.
<h3>Reproduction in Fungus:</h3>
- Most fungi have sexual and asexual reproduction abilities.
- This enables them to adapt to environmental changes.
- When the environment is stable, they can spread swiftly through asexual reproduction.
<h3>Asexual reproduction in fungi:</h3><h3>fragmentation </h3>
- Hyphae fragments can sprout new colonies.
- A fungal mycelium fragments as it splits into pieces, with each piece developing into a new mycelium.
<h3>budding</h3>
- Most yeasts and some filamentous fungi engage in budding, which is an additional asexual reproduction strategy.
- This process results in the development of a bud, whose cytoplasm is continuous with that of the parent cell, on the surface of either the yeast cell or the hypha.
<h3>producing spores.</h3>
- The majority of fungi reproduce by producing spores, which can endure harsh conditions including extreme cold and a lack of water.
- Depending on the species and environmental factors, asexual and sexual meiotic spores can both be formed during mitosis.
- A diploid and haploid stage coexist in the majority of fungi's life cycles.
<h3>Sexual reproduction in fungi:</h3>
Plasmogamy, karyogamy, and meiosis are the three successive steps of sexual reproduction in fungi.
<h3>Plasmogamy:</h3>
Plasmogamy unites two compatible haploid nuclei by joining two protoplasts, or the contents of two cells.
<h3>Karyogamy: </h3>
- These haploid nuclei fuse together during karyogamy to form a diploid nucleus (i.e., a nucleus containing two sets of chromosomes, one from each parent).
- The zygote is the name for the cell created during karyogamy.
- In the majority of fungus, the sole diploid cell throughout the whole life cycle is the zygote.
<h3>Meiosis:</h3>
- Meiosis (reduced division) starts the haploid phase, which generates the gametes, and restores the haploid amount of chromosomes.
- With the exception of the zygote, all structures in the bulk of fungi are haploid.
- At the time of zygote formation, nuclear fusion occurs, and meiosis immediately follows.

Answer:
1. air mass -> large body of air with uniform temperature and humidity
2. cyclone -> a severe storm
3. front -> where two different air masses meet
4. source region -> area over which an air mass forms
The HeLa cancer cell lines were first obtained from the cervix of Henrietta Lacks, a patient who had cervical cancer. The HeLa cancer cell lines are known to be the immortal cell line as the cells do not enter cellular senescence and undergo cell death. The HeLa cells can thus be cultured in-vivo for very long time under the controlled lab conditions. The primary reason for their immortality is the activity of the telomerase in restoring the length of telomere (protective end of DNA which gets shortened after every cell division). This process helps the HeLa cell in circumventing the Hayflick limit of cell division.
