Answer:
1. fragmentation- genetically identical
2. budding- genetically identical
3. haploid cells from two different mycelia fuse to form a zygote- genetically distinct
4. one hyphae creates spores through mitosis- genetically identical
Explanation:
1) Fragmentation is a form of asexual reproduction i.e. one parent, employed by certain organisms including fungi in which a FRAGMENT breaks off from the single parent to produce new cells. Since it is an asexual reproduction, the resulting cells will be GENETICALLY IDENTICAL.
2) Budding is another form of asexual reproduction that fungi undergoes e.g yeast. In the budding process, buds develop on the parent cell and later grow into mature cells that are GENETICALLY IDENTICAL to the parent cell.
3) In fungi, two different mycelia can produce haploid sex cells via the process of meiosis, which then fuse to produce a ZYGOTE. This method is a sexual means of reproduction. Hence, the zygote formed will be GENETICALLY DISTINCT from the parent.
4) Hyphae (threadlike filaments) of a fungi can via MITOTIC DIVISION produce spores, which then germinates under favorable conditions and grows into a new fungus. This new fungus cell is GENETICALLY IDENTICAL to the parent hyphae.

Unlike carbon-based fuels like coal, natural gas, and petroleum, nuclear energy does not release greenhouse gases into the atmosphere. Therefore it does not contribute to global warming.
Explanation:
Nonetheless, nuclear energy is not widely adopted for energy because of its safety concerns. Fission energy is harmful to the environment because of nuclear waste it generates. How this nuclear waste is stored is very important because leakage can lead to contamination of an environs with lethal radioactive elements.

Layers of cross-bedded sand can be indicative of a DESERT environment wind is responsible for the formation of these sedimentary structures. Sand dunes preserved in rocks can be quite large. These structures form as a result of the migration of dunes due to the action of the wind. Dunes are not often preserved but a few can be observed in thick sandstone units.
