Answer and Explanation:
cross: BbTt x bbTt
<u>Cross for B gene</u>
Parental ) Bb x bb
Gametes) B b b b
Punnet square) B b
b Bb bb
b Bb bb
F1) Genotypic proportion: 2/4=1/2 Bb : 2/4=1/2 bb
Genotypic ratio 1:1
Phenotypic proportion: 2/4=1/2 B- : 2/4=1/2 bb
Phenotypic ratio 1:1
<u>Cross for T gene</u>
Parental ) Tt x Tt
Gametes) T t T t
Punnet square) T t
T TT Tt
t Tt tt
F1) Genotypic proportion 1/4 TT
2/4 Tt
1/4 tt
Genotypic ratio 1 : 2 : 1
Phenotypic proportion: 3/4 T-
1/4 tt
Phenotypic ratio 3 : 1
• Offspring are genetically identical to parent-asexual reproduction
Fungi reproduce asexually on different ways such as fragmentation, budding, or producing spores(asexual spores, which are produced by one parentand thus, genetically identical to that parent).
• Offspring genetically distinct-sexual reproduction
Sexual reproduction introduces genetic In fungi, there are two ways(two mating types):both mating types are present in the same mycelium (homothallic) or mycelia require two different mycelia (heterothallic).
Nonpoint source pollution is a greater hazard, because scientists are not able to identify a single location the pollution came from. It is harder to find a solution if they are unable to find the source.

have a great day.
Answer:
Nonrenewable Resources take longer to be replenished, reneweable resources are easily replenished and easily accessible.
Explanation:
If something is Nonrenewable; for example fossil fuels like coal, oil, and natural gas, then that means that the organic matter is limited and not going to grow or be created easily on Earth.
Renewable Resources are usually classified into five categories; Hydro, Solar, Wind, Biomass, and Geothermal. All of these resources are easily accesible and can be used as a natural energy source.
Hope this helped :)
